Research in the Lopatkin lab focuses on understanding how bacterial metabolism contributes to the spread of antibiotic resistance. We do this using a combination of systems and synthetic biology: predictive mathematical modeling with experimental validation. The ultimate goal is to elucidate key underlying principles that govern the spread of resistance in microbial populations so that we can leverage these dynamics to develop effective therapeutic strategies.

According to their recent publication, the Lopatkin Lab determined that because plasmid conjugation is a major mechanism that underlies the spread of antibiotic resistance, and because plasmid fitness costs are known to impact long‐term growth dynamics of microbial populations, the hours immediately following conjugation may be critical for plasmid prevalence as they demonstrated in silico. Today, Hannah Prensky (BC '22) joins us to discuss her contributions to research on this important topic as well as what it's like to work as a research assistant under the guidance of Professor Allison Lopatkin.
A roundup of the latest research achievements by the College’s faculty members.
This year, U.S. Antibiotic Awareness Week takes place Nov 18–24. Dr. Allison Lopatkin, who investigates the mechanisms underlying the evolution of antibiotic resistance and joined the Department of Biological Sciences at the start of this year, joins us today to discuss her work, computational biology more broadly, and mentoring in the lab.
