    UVA ChemE Professor’s Agricultural Biotech Startup Reaps Competitive Grant from Virginia Catalyst

    January 13, 2020

    Lytos Technologies, an early-stage startup company co-founded by chemical engineering associate professor Bryan Berger, and its UVA and Virginia Tech partners, have received a $500,000 grant from Virginia Catalyst to continue work on safe, effective alternatives to chemical pesticides for agricultural applications.


    Virginia Catalyst is a non-profit corporation funded by the Virginia General Assembly and several of the state’s leading public universities, including the University of Virginia. Its competitive Grant Funding Program supports collaborative life- and bioscience research and commercialization of new innovations with the potential to address large, unmet needs for improving human health; create high-value jobs in Virginia; and strengthen the state’s competitive advantage in life science technologies, according to a news release from the Office of the Governor.

    The project Lytos is working on with its university partners, “Design and implementation of green, enzymatic biofungicides for pre- and post-harvest crop protection,” is one of six collaborations to win a grant in the organization’s 10th and latest round of funding. This round’s grants total $3.3 million.

    Berger co-founded Lytos with his former student, Evan Eckersley, at UVA. The award will support their ongoing efforts to develop and commercialize effective “green” biocides as well as targeted applications for pre- and post-harvest crop protection. Lytos works with Virginia wine grape growers, Berger said, to find organic biopesticides that outperform traditional chemicals.

    “In working directly with local wineries, we will be able to deliver products that will contribute to the growing sustainable, organic wine movement,” he said.

    Graduate Student From Lazzara Lab Wins Presentation Award

    October 23, 2019

    Evan Day, a student in Associate Professor Matt Lazzara’s lab, is the 2019 winner of the W.H. Peterson Oral Presentation Award given by the Division of Biochemical Technology of the American Chemical Society. The award is for his presentation on work that led to the creation of a new tool to evaluate the in vivo (taking place in a living organism) efficacy of targeted inhibitors for cancer. Evan presented the research, titled “Engineering a bioluminescence-based protein kinase reporter for in vivo, longitudinal studies of receptor tyrosine kinase inhibitor response,” at the division’s annual meeting in Orlando, Fla., last spring. The award will be presented at the American Chemical Society Biochemical Technology Division 2020 annual meeting, which will be held in March in Philadelphia.

    “The deployment of this tool will lead to better preclinical in vivo data, and greatly reduce the numbers of animals needed to evaluate drug efficacy, at least for a particular class of drugs,” Professor Lazzara said. “The basic design principle behind it may eventually be adapted for use with other types of drugs.”

    Nate Sallada, a Ph.D. student in Associate Professor Bryan Berger’s lab, recently received a National Science Foundation Non-Academic Research Internships for Graduate Students INTERN award. INTERN opportunities provide supplemental funding for students already supported by an active National Science Foundation grant, allowing them to pursue activities and training that complements their academic research experience.

    The funding will support collaborative work with researchers at Merck & Co., which follows up on previous work with the pharmaceutical company that is pending publication. The research involves developing new, protein-based formulating agents to improve drug delivery for the treatment of diseases. Nate will work at Merck in winter and spring of 2020 with Matthew Lamm, director of preformulation at Merck, to further investigate the mechanism of improved drug delivery using the designed proteins developed at UVA.

    Chemical and Biomedical Engineering Students’ Summer Work Aims to Prevent Spread of Infection

    August 22, 2019

    This summer, rising third-year chemical engineering major Molly Caveney (right) and Allie Boboltz, a biomedical engineering major, worked on using engineered proteins to break down biofilms and prevent the spread of infection, with chemical engineering associate professor Bryan Berger.

    “The benefit of engineered proteins is that they are both effective in breaking down biofilms and organically derived, meaning that they won’t contribute to antimicrobial resistance,” Allie said. “We have been working this summer to isolate, express and purify proteins in E. Coli bacteria that could potentially be used against biofilms. This involves cloning my gene of interest into a bacterial plasmid, then using the plasmid to over-express my target protein in E. Coli. My next step is to apply these proteins to biofilms and observe the protein’s activity on the biofilm.”

    When they were not in the lab, Molly and Allie went on ice cream tours throughout the Charlottesville area.

    ChemE Undergrad Kevin Bahati Named American Chemical Society Scholar

    August 22, 2019

    Kevin Bahati, a fourth-year chemical engineering major and undergraduate research assistant in Assistant Professor Geoff Geise’s lab, has been named an American Chemical Society Scholar. Kevin, who spent the summer working as a facilities engineering intern at Southwestern Energy in Texas, joined Professor Geise’s lab as a first-year student because of the group’s polymer-based water purification research.

    Kevin was raised in Africa and lived in Congo, Zambia and Uganda before immigrating to the United States through a refugee program in 2014. He has experienced first-hand living without reliable access to clean water. It is motivation to use his education and research background to make contributions that will help improve living conditions in the developing world.

    “My end goal is not just about providing clean water,” he said. “I want to contribute to the progress taking place in the developing world.”


    ChemE Undergraduates Spend Summer Combating Harmful Algal Blooms

    August 14, 2019

    Rising third-year chemical engineering majors David Lee of Yorktown, Va., and Geoffrey Burns of Concord, Mass., spent the summer at UVA Engineering in the lab with Associate Professor Bryan Berger working on finding a more effective and environmentally friendly way to treat harmful algal blooms.

    “The most common treatment is copper sulfate, which is super toxic and essentially kills the algae and everything else living in the lake or other body of water,” Geoffrey said. “So we developed an enzyme that works to specifically target the algae and kill it without harming the other organisms in water.

    “We’ve spent this summer researching the effects of the enzyme on different types of algae and finding ways to increase the enzyme’s buoyancy so that it can better target the algae that grow mainly on a body of water’s surface.”

    When they were not doing research, their activities included picking peaches at Carter Mountain with friends.
