B.S. in Chemistry — Furman University (2018)
Ph.D. in Chemistry — Stanford University (2023, Advisor: Justin Du Bois)

Clay works on developing small molecule inhibitors of agr quorum sensing in gram positive bacteria. After obtaining a B.S. in chemistry from Furman University in Greenville S.C., Clay completed graduate work in the laboratory of Justin Du Bois at Stanford University studying the total synthesis of bis-guanidinium neurotoxins. Outside of lab, Clay enjoys rock climbing, running, and watching bad science fiction.

B. A. in Chemistry — Carleton College, 2022

Isabel grew up in San José, CA, and moved to MN to attend Carleton College, where she majored in chemistry and worked on organocatalysis mechanism research with Prof. Gretchen Hofmeister. She also spent a summer at Virginia Tech with Prof. Emily Mevers working on natural product discovery. In the Blackwell lab, her research focuses on synthesizing AHL-like probes to understand the structure-activity relationship between AHLs and quorum sensing agonism and antagonism in LuxR-type receptors. Outside of lab, she enjoys spending time being active outdoors, playing board games and tabletop roleplaying games, and playing the piano.

B.S. in Chemistry and Cellular & Molecular Biology — Belhaven University, 2023

Madison is originally from Arkansas and she attended Belhaven University in Jackson, Mississippi, where she double majored in Chemistry and in Cellular and Molecular Biology. As an undergraduate, she worked with Professor Reid Bishop to study the thermodynamics of Warfarin binding to human serum albumin. She also participated in an REU at the University of Mississippi synthesizing near-infrared fluorophores for biological imaging. Now, Madison synthesizes novel Gram-negative quorum sensing modulators and studies their activities. When she’s not in lab, Madison loves spending time with friends, reading, and playing sports.

B.S. in Biochemistry – Beloit College

Kamila grew up in Medellín, Colombia, and the suburbs of Chicago. She earned her bachelor’s degree in Biochemistry from Beloit College, a liberal arts institution in Wisconsin. During her undergraduate studies, she completed a summer research internship at Drexel University with Professor Priscila Sato, investigating G-protein–coupled receptor kinases and their roles in cardiac physiology. She later interned at Caltech in Professor Frances Arnold’s laboratory, where she explored carbene and nitrene-transfer reactions. Outside of the lab Kamila likes to read, draw, and weightlift.
