    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.


    Sean Bannon Is Going to NAMS 2022 with Assist from Travel Award

    February 08, 2022
    Sean-Bannon_7524_brief.jpg

    Sean Bannon, a Ph.D. student in associate professor Geoff Geise’s polymer membrane lab, has been selected for an Elias Klein Founders’ Travel Supplement, which is given by the North American Membrane Society. The award will reimburse Bannon up to $500 for travel expenses to attend NAMS 2022, the society’s annual meeting, to present his research, “Salt transport in sulfonated polysulfone membranes exposed to high salinity.”

    The research will provide insight into how desalination membranes work and into how membranes could be further improved to facilitate water purification and address growing global demand for clean water.

    Congratulations, Sean!


    UVA Team Advances to Semifinal Round of $4 Million Clean-Energy Technology Competition

    January 06, 2022

    A research team led by members of the Department of Chemical Engineering faculty at the University of Virginia has advanced to the second phase of a three-phase, $4 million competition sponsored by the U.S. Department of Energy. The DOE’s American-Made Geothermal Lithium Extraction Prize is designed to speed development of technologies and techniques for direct extraction of lithium from geothermal brines found in California’s Salton Sea. Lithium – of which all but 1% of the U.S. supply is imported – is a critical material in batteries for electric vehicles and grid-scale electricity storage.

    Associate professors Geoffrey Geise and Gary Koenig and assistant professor Gaurav “Gino” Giri, with industry partner PowerTech Water, make up Team TELEPORT, named for the project’s title, Targeted Extraction of Lithium with Electroactive Particles for Recovery Technology. The team’s concept is one of 15 selected for a $40,000 award and eligibility for the competition’s second phase.

    Bev Miller (left, with fellow ChemE Ph.D. student Ashley Conley), a chemical engineering Ph.D. student in assistant professor Steven Caliari’s biomaterials lab at the University of Virginia School of Engineering and Applied Science, recently attended the American Institute of Chemical Engineers Annual Meeting in Boston with support from a 2021 Women in Chemical Engineering Travel Award.

    The award included Miller’s registration for the meeting, an $800 stipend for travel expenses and complimentary membership in AIChE for the 2021 and 2022 calendar years. Earning the award allowed her to present during a poster session for postdoctoral candidates and give a talk on her research, “Guest-Host Supramolecular Assembly of Injectable Hydrogel Nanofibers for 3D Cell Encapsulation and Pelvic Organ Prolapse Repair,” during the conference.
