LINDSEY "LES" SHAW, B.Sc. (Hons), Ph.D. When Les was 13 he had major surgery to implant pins in his hip, correcting a growth defect. Unfortunately, as with a lot of surgeries, this resulted in a S. aureus biofilm infection caused by the indwelling pins that was not fully resolved until they were removed 5 years later. As such, Les has been in and/or around hospitals, bacteria, and antibiotics for a good portion of his life. This lead him to pursue a B.Sc. (Hons) degree at the University of East Anglia (Norwich, UK), which he obtained in 1999. For his honors thesis, he worked in the laboratory of Dr Richard James (now at Nottingham University, UK) performing a structure-function study of E. coli colicins. From there, he conducted his doctoral work in the laboratory of Dr Simon Foster at the University of Sheffield (Sheffield, UK). Here he focused on the role of secreted proteases in the virulence of S. aureus - the bacterium that caused him so many problems early on in life. As part of his doctoral training he spent the winter of 2001 studying in the laboratory of Dr Jan Potempa at the Jagellonian University in Krakow, Poland. Upon returning from Poland, and completing his PhD studies, he moved to the laboratory of Dr James Travis at the University of Georgia in fall 2002. Here he worked on the proteolytic enzymes of S. aureus, as well as those from a number of other pathogenic bacteria. In the summer of 2006, Les left UGA and moved to the University of Missouri-Columbia as a research assistant professor in the laboratory of Dr George Stewart, working on the quorum sensing systems of S. aureus. The following summer, in 2007, Les departed UMC, and joined the faculty of USF as an Assistant Professor in the Department of Cell Biology, Microbiology & Molecular Biology. He served as departmental director of graduate studies from 2009 - 2018, was promoted to Associate Professor with tenure during the summer of 2012, and became a Full Professor in summer 2016. Les was appointed departmental Associate Chair in the fall of 2019, and served as Department Chair for AY 2021 - 2022, before returning to his role as Associate Chair. He was named the Richard & Patricia Wood Endowed Chair in Natural Sciences in the Summer of 2023. Les holds joint appointments in the Division of Infectious Diseases at the USF Morsani College of Medicine as well as in the Department of Global Health at the USF College of Public Health Professionally, he became a permanent member of the NIH Bacterial Pathogenesis (BACP) study section in 2018, and the Microbiology & Infectious Diseases (MID) study section in 2022. Les was elected as a AAAS Fellow in 2019. In 2024 he was named Director of the USF Center for Antimicrobial Resistance (CAMRA). As a result of those early years spent dealing with a S. aureus infections, and taking endless antibiotics, the Shaw lab appropriately works on the virulence mechanisms of this dangerous pathogen, whilst at the same time seeking to develop new antibiotics for the treatment of drug resistant bacterial infections.
