    Chemical engineering majors Elli Brna (from left) Jack Kilduff, Ethan Kutner and Brandon Hudson competed in the ChemE Sports spring competition with teammates (not pictured) Avery Baker and Nitin Elavarasu.

    The University of Virginia Department of Chemical Engineering fielded two teams in the recent ChemE Sports spring competition, and both finished with impressive performances.

    The team of fourth-year Brandon Hudson, third-year Ethan Kutner and second-year Avery Baker placed third among a total of 17 teams, while fourth-year Jack Kilduff, first-year Elli Brna and second-year Nitin Elavarasu finished in sixth place.

    Professors Eric Anderson and George Prpich coached the teams.

    ChemE-Sports is a simulation-based competition hosted by PetroSkills twice a year – each coinciding with American Institute of Chemical Engineers events, the organization’s annual meeting in the fall and regional student conferences held in the spring. This spring’s virtual competition occurred during the mid-Atlantic region’s student conference and drew participants from around the world.

    During the competitions, teams work together on a plant operation task, such as separating chemical compounds using a distillation column, all the while reacting to programmed failures in the system, such as pump failures or steam valves shutting off. Teams earn points for producing the most product that meets purity specifications while minimizing the number of alarms and time in alarms.

    “ChemE Sports competitions are great events for chemical engineering majors across all four years to get together and practice weekly for a competition that enhances knowledge in industrial operations and safety in the chemicals industry,” Kilduff said. “The competition was quite a lot of fun this year, and the team is looking forward to next fall!”

    CHEERS 2022, UVA’s annual Chemical Engineering Research Symposium, took place Friday, March 11, bringing together graduate students, faculty, alumni and industry experts to showcase research in the department and create networking opportunities for students.

    This year’s keynote speaker was Tucker Norton, Cyrel Solutions general manager at Dupont. Norton, a Louis Rader Award recipient and 1997 chemical engineering Ph.D. alumnus, also received his MBA from the Darden School of Business.

    In addition to students’ oral presentations and poster sessions highlighting research ranging from battery technology to tissue engineering, the daylong symposium included an industry panel in which CHE alumni shared experiences, insights and advice for Ph.D. students preparing to enter the workforce.

    Alan Hunter (Ph.D. 2002), a senior director at AstraZeneca, kicked off the panel with a short presentation. He was then joined by Erica Hui (Ph.D. 2021), an investigator in downstream process development at GSK; Tara Tibbs Jones (M.S. 2001, Ph.D. 2003), vice president drug substance manufacturing at Amgen; and Rob Kasprow (M.S. 1997, Ph.D. 2000), an executive director at Merck.

    CHEERS is organized by members of the Chemical Engineering Graduate Board, led by this year’s coordinator Tori Vigil.

    “CHEERS not only showcases the great research coming out of our department, but also the supportive community that we have built,” said Vigil, a Ph.D. student in her second year. “Seeing our awesome alumni is a reminder that at the end of the day, a CHE Ph.D. from UVA not only represents a rigorous education, but also great personal and professional growth.”

    Other Graduate Board members who were instrumental in organizing the symposium were Greg Grewal, the CHEERS 2020 coordinator, and president Rhea Braun, Vigil said, adding, “Our department first-year students were a tremendous help in day-of behind-the-scenes support.”

    CHEERS 2022 was sponsored by GSK.


    Lazzara Lab Wins Presenter Awards at Commonwealth of Virginia Cancer Research Conference

    February 22, 2022

    Brooke McGirr Brown and Karl Kowalewski, Ph.D. students in associate professor of chemical engineering Matt Lazzara’s lab at the University of Virginia, recently won breakout session presentation awards at the Commonwealth of Virginia Cancer Research Conference.

    Brown earned the breakout session award for presenting, “Signaling regulation of epithelial-mesenchymal transition in the hypoxic tumor microenvironment of pancreas cancer.” Kowalewski won for “Cancer-associated fibroblast signaling regulation of epithelial-mesenchymal transition in pancreas cancer.”

    Cancer of the pancreas is one the most deadly cancers, in large measure because the tumors don’t respond well to standard therapies. Both Brown and Kowalewski focus on the mechanisms that cause the tumor cells to resist therapy, with the goal of identifying what processes to target with cancer-killing drugs to overcome the resistance and improve outcomes. Kowalewski specifically homes in on how fibroblasts, cells that form connective tissue and scarring, contribute to therapy resistance.

    The annual Cancer Research Conference, hosted by Virginia Commonwealth University’s Massey Cancer Center, invites cancer research trainees, such as graduate students and postdoctoral and clinical fellows, to present their work in oral sessions. A goal of the conference is to promote collaboration and networking among clinicians and researchers interested in basic, translational and clinical cancer research.
