معرفی
Petra Levin is the George William and Irene Koechig Freiberg Professor of Biology and Associate Chair of Faculty Research and Development in the Department of Biology at Washington University. She holds a PhD from Harvard University and leads the Levin Lab, which investigates fundamental processes in bacterial systems including cell growth regulation, antibiotic resistance mechanisms, and cell division dynamics. Her research bridges microbiology, biophysics, and molecular genetics.
Education includes:
- PhD in Biological Sciences, Harvard University
Her research explores how bacteria adapt to environmental stressors such as nutrient limitation, with implications for antibiotic resistance and persistence. Key areas include:
- Coordination of cell size and growth rate with nutrient availability
- ppGpp-mediated antibiotic tolerance during starvation
- Regulation of FtsZ assembly for spatial/temporal control of division
- Membrane composition's role in determining cell envelope capacity
Her recent publications demonstrate strong focus on bacterial stress responses, cell wall plasticity under varying pH conditions, and mechanistic insights into persister cell formation. Article themes consistently address microbial physiology under environmental constraints.
Dr. Levin's laboratory employs genetic, biochemical, and advanced imaging approaches to study bacterial systems. She mentors graduate students and postdoctoral researchers while collaborating widely on antibiotic resistance initiatives.
