Principle Investigator

Bryan Davies, PhD

Bryan completed his BSc in Biochemistry at McMaster University, PhD in Molecular Biology at MIT, and postdoctoral fellowship in infectious diseases at Harvard Medical School. He is an Associate Professor in the Departments of Molecular Biosciences and Medical Education. His research interests include antimicrobial discovery and development, bacteria-host interactions, and microbe engineering.


Research Scientist

Jennifer Parker, MSc

Jennifer completed her MSc in Environmental Health at the University of Washington. She has conducted research in diverse disciplines including environmental microbiology, plant pathology, and public health microbiology. Her current work is focused on discovering novel naturally-occurring antimicrobial peptides (microcins), elucidating their role in modulating the host microbiome, and engineering bacterial delivery systems to provide microcin-based therapeutics.

Postdoctoral Fellows

Renee Fleeman, PhD

Renee earned her PhD from the University of South Florida where she worked discovering novel small molecule antimicrobials. Her current work focuses on obtaining a better understanding of the innate immune system evasion strategies used by K. pneumoniae and using these interactions as targets for adjunctive therapeutics.

Justin Randall, PhD

Justin earned his PhD at the University of Michigan studying bacterial DNA repair. He joined the Davies lab to pursue more translation research and is now developing peptide therapeutics targeting Vibrio cholerae.

Jeff Cole, PhD

Jeff earned his PhD from East Carolina University where he worked on developing bioinformatics and deep learning implementations to identify and characterize the molecular evolution of venom proteins in wandering spiders. He is now be using deep learning techniques to characterize and design antimicrobial peptides and proteins.

Graduate Students

Xun Wang

Xun received her BSc in biology from Tsinghua University in Beijing, China. Since joining Davies lab, she developed an interest in using microbiology to pave a way towards drug development. She studied how A. baumannii survive on dry surfaces for extended periods and spread within hospitals. Her current focus is on screening and engineering of novel antimicrobials. 

Greg Knauf

Greg received his BSc in Biology with emphasis on microbiology at the University of Texas at Austin. His previous work studied the mechanism of action of the antimicrobial benzalkonium chloride. His graduate work focuses on bacterial pathogen strategies for host colonization and species specific biologic approaches to addressing pathogen colonization and infection.

Sun-Young Kim

Sun-Young received his BSc in Microbiology from Pusan National University in Pusan, South Korea. His interest in microbiology includes host-microbe interaction, synthetic biology, and biotechnology. Currently, he is working on the elucidation and application of the secretions system in Escherichia coli for heterologous peptide production. His future goals are improving the secretion system, and showing applications such as bacteria-based peptide delivery to hosts.

Kyra Groover

Kyra received her BSc in Biology from Texas A&M University in College Station, Texas. Her research interests broadly include developing novel therapeutics targeting infectious diseases. In the Davies Lab, her focus will be centered around developing and implementing novel antimicrobials.

Angela O’donnell

Co-advised with Howard Ochman. Angela graduated with a bachelor’s degree in Biology from Smith College in Northampton, Massachusetts. She is broadly interested in discovering and engineering new antimicrobials. She is also interested in exploring how the study of antimicrobial evolution can inform and guide research. 

Research Associates

Jessica Selim

Jessica received her BSc in Human Biology at the University of Texas at Austin. She joined the Davies lab to focus on microbiome-based peptide delivery with a broader goal of developing therapeutics targeting chronic pain. 

Gillian Davidson

Gillian received her BSc in Biochemistry from the University of Texas at Austin. She joined the Davies lab as an undergraduate student her sophomore year. Her research interests include drug development against multi-drug resistant pathogens. As a research associate, she will continue studying novel peptide antibiotics and antimicrobials.
