Dr. Valla has won recognition for her work on cleaner fuels while working in industry and academics and is the leader of the iKnowGreen Team. iKnowGreen at the University of Connecticut, is a place for students, teachers, and UCONN engineers to explore green energy together.

Grad Student Spotlight: Andrea Kadilak

By Jayna Miller

andrea1The Chemical Engineering graduate program at UConn provides the opportunity for students to obtain a thorough understanding of the principles of chemical engineering and gain the practical skills needed to succeed in the workplace. Students have the chance to get involved in a number of useful research and teaching opportunities to better prepare for their future.

Grad student Andrea Kadilak has taken advantage of many of the programs and activities that UConn had to offer. Her most rewarding experience during her years at the university was her involvement with the NSF GK-12 Fellowship Program, where she worked with high school students to inspire an interest in science.

“I worked with students at Windham Tech to raise awareness of career options in physics, chemistry, and engineering – I also showcased the fun side of science through experimental demonstrations,” she says.

In addition to the NSF GK-12 Fellowship, Andrea was also involved in a number of on-campus engineering groups. She is currently the Chairperson for the CBE Grad Student Association, and is the Activities Director for the local chapter of AIChE.

“These leadership positions provide an opportunity for me to plan events, network, and organize meetings that bring together all of the engineering programs at UConn, to create a collaborative atmosphere and provide a wide variety of research opportunities for students,” she says.

These positions were not Andrea’s first leadership and work experiences. Prior to attending UConn, she worked as a Process Engineer at Solutia for two years, but decided that she wanted to return to research in a university setting.

Andrea’s research currently focuses on the NSF EFRI Termite Grant, which involves working with a team of engineers, including CBE professor Leslie Shor, to simulate the termite digestive tract in a micro-fluidic device. Termites are able to efficiently break down cellulose and other woody materials into biofuels to use as a food source. Through this research, the team hopes to culture the digestive bacteria in the micro-fluidic device in order to observe it, and perhaps recreate the biofuels, which will have an environmental benefit because it can reduce fuel needs.

Andrea has received multiple accolades for her research at UConn.  She received the Women’s Initiative Committee Travel Award at the Minnesota AIChE Meeting in 2011, and earned 2nd place in the Poster Presentation Competition. In addition, she was the recipient of an ACS Meeting Certificate of Merit in 2012.

In the future, Andrea hopes to work in industry, but also to continue her personal research. She enjoyed working in a chemical plant in the past, but would like to achieve a balance and bridge the gap between research and the implementation of research practices in a process.

Leslie Shor Named a DuPont Young Professor

Dr. Leslie Shorshor caption of Chemical & Biomolecular Engineering specializes in recreating very small habitats – smaller than the width of a human hair in some cases. Building from scratch a simulated habitat that might sustain up to a thousand different organisms that each need different conditions to survive is no easy trick.

But the potential payoffs can be huge – more sustainable agriculture, better ways to fight infection, or more sustainable energy production from biofuels.

One particular project in her lab prompted DuPont to name her a 2014 Young Professor. The annual program recognizes professors engaged in innovative research that addresses global challenges regarding food, energy and production. Shor, one of 10 professors to receive the appointment, will receive $75,000 over the next three years to support their research.

The project that won DuPont’s attention is the same one that won a Grand Challenges Exploration grant of $100,000 from the Bill and Melinda Gates Foundation in 2012.

Hunger and poverty affect 1 billion people. Population growth, changing consumption habits, and a shifting climate will only magnify the problem. So developing new ways to increase food production is crucial. To that end, Shor and other researchers in her lab hope to find a new way to increase crop yields. For this research, she teamed up with Daniel J. Gage (Molecular & Cell Biology), a microbiologist with expertise in the rhizosphere. That’s the region of soil around a plant’s roots where crucial nutrients are absorbed. Beneficial bacteria in the rhizosphere can help plants by inhibiting pathogens and producing antibiotics. The rhizosphere is also home to protozoa – a kingdom of single-celled animals with the ability to move efficiently in soil. That’s where Shor comes in, with her knowledge of artificial microbial habitats and how protozoa migrate in micro-structured environments.

With her collaborators and students, Shor seeks to increase crop yields by using protozoa to distribute bacteria along growing roots. Currently, applications of biologicals or agrichemicals are not targeted, leading to inefficiency and adverse environmental impacts. Solving one problem might lead to the creation of several more. In Shor’s lab, they’re trying to use the environment as part its own solution.

“The soil system is an incredibly complex habitat, and it’s home to organisms from all five kingdoms – plants, animals protista fungi and archae – are all present in the soil,” she said. They interact with each other, and with the air, water, organic matter and soil grains in complex ways. Typically, microbiologists will take organisms out of their natural habitat and put them into an overly simplified lab habitat.

“There’s no microstructure in those habitats, typically,” she said. “Our microhabitats are not the same thing as real soil, but they do contain some of its features. Our microhabitats offer a window into the microworld.”

Senior Design Day 2014

By Sydney Souder

team1The excitement was evident as more than one thousand visitors entered Gampel Pavilion for UConn School of Engineering’s Senior Design Day on Friday, May 2, 2014. The mezzanine of the Pavilion was lined with posters and displays outlining the projects of sixteen teams of senior class Chemical & Biomolecular Engineering majors.

Friends and family visited each team’s display to view the results of a year of hard work. Faculty and industry judges stayed longer, asking probing questions and listening carefully as the students explained the intricacies of their projects.

“It’s rewarding to get positive feedback on the work you’ve done all year,” says William Hale whose project sponsored by Aero Gear won second place in the department.

“Besides your grades and resume, nothing is more powerful than a strong story. An in-depth design experience sounds great to companies hiring our students,” says Prof. Jeffrey McCutcheon, a mentor for several capstone design projects.

The Department of Chemical & Biomolecular Engineering prides itself on its ability to provide students the critical tools necessary for their future successes. The rigorous four-year CBE curriculum provides students in-depth skills in science, technology, engineering and math (STEM). As the last step before graduation, the department requires that students work in teams and showcase their proficiencies in a final challenge: capstone design.

“Capstone design has been retooled by our talented faculty, and is now a truly unique experience for our seniors and industry sponsors alike,” says Doug Cooper, Head of the CBE department.  Students, guided by faculty and industry mentors, are tasked with analyzing a chemical system, process, or component, subject to economic, environmental, and health and safety considerations.

“Our students worked on 14 different projects ranging from developing an artificial kidney using advanced manufacturing techniques, to developing a continuous process for producing coffee,” says Prof. Leslie Shor, this year’s Capstone Design faculty leader.

One group led by Prof. McCutcheon collaborated with KX Technologies, a Marmon Water/Berkshire Hathaway Company.  During the design team’s journey of discovery and invention, they visited the company headquarters in West Haven, CT, to present their work. Technology experts from the company were in attendance and engaged the students with questions and advice.

“Capstone design has allowed me to put technical knowledge to use in a real world situation. I am grateful for the opportunity to work hands-on with a company, and I think that I will take away valuable time management and interpersonal skills,” says Diva Evans, one of the three group members to visit KX Technologies.

Beyond adding a substantial boost to a resume, this comprehensive program gives students the early experience to think, work and act as an engineer. “You’re not just doing problems out of a book,” says James Cioffi, another member of the second place team, “you’re getting real-world results, and it’s a new thing to be impressed with the work you’ve done.”

The number and diversity of projects in this year’s program made this a challenging, but exciting year for the seniors, and the outcome has no doubt been of benefit to the students, and will be to their future employers.

Students are faced with challenges in planning, prioritizing and communicating, even adapting should something go wrong. “I think many students are also learning something about themselves, about their own strengths and weaknesses, likes and dislikes, and maybe what sort of work they would like to do next year,” says Prof. Shor.

By Sydney Souder

Picture of Donald VictoryThe University of Connecticut’s Academy of Distinguished Engineers inducted two Chemical Engineering alumni in a day of celebration on May 1, 2014. Donald J. Victory (Cheg ’81) and John Wyatt (Cheg ’73) returned to their alma mater to receive the prestigious acknowledgment. They both took the opportunity to reengage with the faculty and students from Chemical & Biomolecular Engineering during their day of honor. The Academy grants membership to truly outstanding alumni for distinguished professional achievement contributing to engineering and engineering management in the highest tradition of the School. To be eligible, candidates must have graduated from the University at least ten years prior, and must have made meritorious engineering, managerial or policy contributions throughout their career.

Picture of John Wyatt

Mr. Victory is Process & Risk Engineering Manager for ExxonMobil Development Company in Houston, TX. He leads a global team responsible for process design, process safety, and facilities layout for major upstream projects. The UConn alumnus began his career with Exxon Production Research Company as a facilities engineer in 1981 and advanced through a series of engineering design, operations, and project management positions in the U.S., Malaysia, Indonesia, Russia, Qatar and Japan. His contributions include the development of the Controlled Freeze Zone (CFZ) process for more efficient CO2 removal from natural gas. Mr. Victory led the conceptual design of an offshore platform that provided one-third of the domestic gas supply to peninsular Malaysia, and he is listed as an inventor on over a dozen U.S. patents.

John Wyatt, Ph.D., is a Senior Advisor for Carmagen Engineering with expertise in the areas of reactor engineering and exothermic reactor safety. Dr. Wyatt retired from ExxonMobil Research and Engineering Company (EMRE) as Team Leader for the Photobioreactor Development team. During his 32 year career with EMRE, he was involved in many core refining processes and cutting-edge technologies. Dr. Wyatt was the Commercial Technology Leader for fixed bed reactor technology and is co-inventor on seven reactor engineering patents. He was instrumental in the development of experimental capabilities and testing protocols to assess the exothermic potential of new catalysts and chemical processes. He also identified the lead cause of temperature non-uniformity in exothermic hydroprocessing reactors and led the implementation of a solution that improved safety and saved ExxonMobil millions of dollars. Dr. Wyatt was an adjunct professor at The Stevens Institute of Technology from 1996-2000.

“These individuals bring lasting honor to their alma mater as practitioners and as citizens,” said Dean Kazerounian during their formal induction ceremony.

Students Design Artificial Kidney with 3-D Printing

Three-dimensional printing has garnered coverage in the popular press for its application in the custom manufacturing of tools and mechanical parts. But six School of Engineering seniors have recently taken the application of the technology into the medical field, using 3-D printing to create body parts.

Under the direction of Anson Ma, assistant professor in the Department of Chemical and Biomolecular Engineering and the Institute of Materials Science, two three-person teams of chemical engineering students were tasked with creating an artificial kidney for their Senior Design Project using 3-D printing technology. 3-D printing is an additive manufacturing method capable of creating complex parts that are otherwise impossible or extremely difficult to produce.

The students participating were: Derek Chhiv, Meaghan Sullivan, Danny Ung, Benjamin Coscia, Guleid Awale, and Ali Rogers. They are one of the first classes of students to partner with a commercial 3-D printing company, ACT Group, to create a prototype.

The challenge the teams set out to tackle is rooted in a very real problem.

The United States Renal Data System reports that, as recently as 2009, End-Stage Renal Disease (ESRD) resulted in over 90,000 deaths. Options for treatment of renal disease are essentially limited to either an organ transplant or dialysis. However, there is a limited supply of transplantable kidneys, with demand far outstripping the supply; and dialysis is expensive and is only a temporary solution.

According to data from the National Kidney Foundation, there are currently nearly 100,000 people awaiting kidney transplants in the United States, yet only 14,000 kidney transplants took place in the country this year. An additional 2,500 new patients are added to the kidney waiting list each month. Faced with these challenges, the two UConn teams set out on a year-long effort to design and develop a prototype of a cost-effective, functional artificial kidney using chemical engineering principles and 3-D printing technology.

“The objective of the design project is to get these students to combine the latest technology and their chemical engineering knowledge, learned over their four years at UConn, to solve a technical problem where we can make a difference,” notes Ma. “Can they push the technology further?”

Guleid Awale, one of the seniors, said the two design teams each took a slightly different approach to the problem. “While the other team utilized techniques such as electrodialysis and forward osmosis in their prototype, our group opted for mainly hollow fiber membrane technology commonly found in traditional hemodialysis treatments.”

Benjamin Coscia ’14 (ENG) explains the hollow fiber membrane technology: “Because 3D printing resolutions are not currently low enough to print a structure which will actually filter blood, the file is of only the shell of the kidney. Hollow fiber membranes will be installed on the inside to do the filtration function. The kidney will then be sealed together using the threads and sealing o-rings. A fluid called dialysate will be circulated on the outside of the membranes, inside of the shell, which will cause flux of components from the blood. A waste stream maintains the person’s ability to urinate. The outside of the shell can be used as a substrate for growth of biological material for ease of integration into the body.”

After undertaking the research and development of the design, the teams designed the prototype using AutoCAD software. Then each team collaborated with UConn technology partner ACT Group of Cromwell, Conn. to select the appropriate polymers, as well as the right printer to use in printing the particular prototype design.

The two teams presented their projects on May 2 at the School of Engineering Senior Design Demonstration Day.

“The biggest challenge in approaching the project was applying the engineering knowledge we’ve gained during our undergraduate years to a more complex biological application,” Awale notes. “This forced us to come out of our comfort zone and rely on our problem-solving skills in order to come up with viable solutions.”

Chemical Engineering Student Garners National Recognition

By Sydney Souder

Fischer

Chemical Engineering junior Ari Fischer has been named a 2014 Udall Scholar. Fischer is UConn’s fifth Udall Scholar and the Department of Chemical and Biomolecular engineering’s second recipient of the competitive scholarship in four years.

The Morris K. Udall and Stewart L. Udall Foundation is one of five federal foundations established by Congress. Since 1996, the program has awarded almost $7 million in scholarships to students dedicated to conserving the environment. “It’s different compared to other scholarships because everyone unites over one passion, even if they come from different backgrounds,” says Fischer.

Of 489 eligible applicants from 47 states and Puerto Rico, the Foundation chose 50 scholars and 50 honorable mentions. This summer, the 2014 Scholars will assemble and meet in Tuscan for an educative leadership orientation.

This scholarship is one in a long run of honors Fischer has accumulated in his three years at UConn. He is the recipient of the John & Carla Augustyn Scholarship, the Connecticut Space Grant Consortium Undergraduate Research Fellowship, the UConn IDEA Grant, an Office of Undergraduate Research (OUR) Travel Grant, and the UConn Academic Excellence Scholarship. Although academics and research have traditionally been Fischer’s strengths, this latest tribute recognizes his service and leadership in a compelling discipline.

Fischer has been empowered by Chemical Engineering since his freshman year at UConn. Despite his love for the field, he acknowledges that Chemical Engineering contributes to many of the problems facing the planet, and he has made it his mission to reverse these effects.

“This is probably the first time I’ve considered myself an environmentalist,” says Fischer, “I’ve been passionate about nature and the environment for a long time, but I didn’t feel a part of the environmentalist community until I came to UConn.”

Fischer has already initiated his own projects committed to the environment. Using his IDEA Grant, Fischer has addressed the oil drilling and waste problems facing the planet by recycling spent coffee grounds into a means for fuels, chemicals and commodities production. Through another recent accolade, a CT Space Grant Consortium award, he is designing an oxygen generator used in carbon dioxide removal. “The frontiers of research offer an exciting new age in energy production,” said Fischer in his application, “and I am committed to designing revolutionary technologies that harness materials and processes in novel ways which enable today’s theories to be implemented on an industrial scale.”

Fischer believes he especially strengthened his environmental outlook last spring as an exchange student in South Korea. He says he will never forget hiking at Bukhansan National Park where he glimpsed the compatibility of the modern city with mountain serenity. It was during this moment of harmony with nature that Fischer was inspired to conserve as much as he could.

Fischer has one year left at UConn, but ultimately plans to earn a PhD in Chemical Engineering. Currently excited by green startups, Fischer hopes to lend his abilities to engineer clean energy alternatives in the future.

UConn hosts 2014 Northeast Regional AIChE Conference

By  Sydney Souder

The Department of Chemical & Biomolecular Engineering was the proud host of the 2014 Northeast Student Regional Conference for the American Institute of Chemical Engineers on April 4-5, 2014. The event attracted more than 300 undergraduate chemical engineering students from 21 schools, traveling from as far as McGill, Cornell and Maine, to as near as UMass and the University of New Haven.

After one and a half years of preparation, the UConn planning committee was excited to see the conference come to life. The day’s success was a remarkable feat considering UConn’s initial plans were to accommodate no more than 200 guests. “I was pleased by the support of our committee and the dedication of our volunteers,” says Nathan Kastner, UConn undergrad (Cheg ’14) and chair of the regional conference.

Each year, the AIChE conference consists of several signature events including the Student Paper Competition, the Chem-E Car race, the Student Poster Competition, and the Chem-E Jeopardy challenge.

ChemECarTestSaturday kicked off with the paper competition where students delivered technical talks on their personal research, followed by a question and answer session led by a panel of faculty judges. Contestants were evaluated on the execution of their designs and results, in addition to their delivery and interaction with the audience. “The quality of the papers and the poise of the students were very impressive this year,” commented Prof. Dan Burkey of the University of Connecticut. Michelle Teplensky of MIT authored the winning paper presentation, “Controlled Release of Type-2 Diabetes Systems.”

Next, twenty-two ambitious students participated in the Poster Competition. Each student’s poster was visited by four judges who assessed the overview of their research findings and approaches. Christina Bailey of WPI took top honors with her project entitled, “Gold Nanoparticle Interactions with Model Biological Membranes.” UConn’s Abbey Wangstrom (Cheg ‘15) took second honors.

ChemECarTakeOffThe Chem-E car race was an intense day-long affair. Leading up to the competition, students designed model-sized cars powered by a chemical reaction. Their machines were required to stop after a specific distance, either by exhausting their fuel supply at just the right moment, or by the triggering of a different chemical reaction.

The 14 competing teams spent the morning preparing the proper mixtures and formulas for their cars, and then held their breaths in anticipation, hoping that their machines would halt at the precise distance—25 meters—revealed just hours before. Cornell’s “Battery Car” entry was the most successful, stopping within inches of the mark. “Each teams’ spirit was contagious, and their focus to rise to the challenge made it a thrilling event and a great day overall,” said Kastner.

ChemEJeopardyThose not involved in the car competition cheered their teams on in the Chem-E Jeopardy challenge. With trivia categories including kinetics, thermodynamics, heat transfer, and more, 12 teams of four proved who was savviest in chemical engineering related topics. During a thrilling Final Jeopardy round, WPI knocked Clarkson University out of first place by betting it all and coming out on top.

The winners of each regional competition will compete on the national stage in Atlanta this November.

The conference concluded with an awards banquet and a keynote speech by UConn alumnus Mark Vergnano, executive vice president of DuPont. Vergnano shared his career journey with the attendees, and the personal values driving both him and DuPont. He also detailed the exciting future in store for the world of chemical engineering and how he would approach starting a career if he were to do so in today’s world.

Vergnano ended with an extended question and answer period, giving students the opportunity to draw on his extensive achievements from their own perspective. “Based on my interaction with the students at this event, I feel very good about the future of Chemical Engineering,” he said afterwards.

 

Faculty Spotlight: Prof. Kristina Wagstrom

By Sydney Souder

Wagstrom CaptionProf. Kristina Wagstrom, through work in her Computational Atmospheric Chemistry and Exposure Lab, strives to improve the science and functionality of computational approaches in air pollution. Her overarching objective is to develop improved regional and global air pollution models for use by the Environmental Protection Agency (EPA) and other state agencies.

Prof. Wagstrom’s current projects here in the Chemical and Biomolecular Engineering Department at UConn include tracking the global transport of particulate matter, and high resolution modeling. One of her goals is to determine the impact of particulate matter generated in different regions and continents on air pollution throughout the globe. Her research group is improving air pollution exposure estimates by coupling local and regional scale models. The overall intention is to create an efficient means of assisting policymakers in their decisions.MapCaptionWagstrom

“I want to be doing something that makes a difference in both the short and long term,” she says, “I enjoy working on projects where I can see the impact in five, six, seven years.”

Prof. Wagstrom’s outlook is strongly influenced by the Science and Technology Policy Fellowship she was engaged in directly before coming to UConn in 2013. This highly competitive fellowship, administered by the American Association for the Advancement of Science (AAAS), immerses outstanding scientists and engineers into federal policymaking to gain a stronger understanding of the intersection between science and policy.

As a fellow, Prof. Wagstrom worked at the EPA and, as a consequence, was able to observe the research grant funding process from an insider’s perspective, as well as how larger government decisions influence what science is funded and therefore carried out.

One outcome from her experience is discovering how to structure research proposals so they will be of use in future policy decision making, and how to organize a project for potential maximum impact. “There are often minor ways to change a project to make it more accessible to policymakers,” she says.

Prof. Wagstrom’s experience will undoubtedly benefit her research and contributions to the department. More information on Prof. Wagstrom’s research is available on her website here.
