2019 Graduates

Kevin MlynekKevin Mlynek

Kevin received his BS in environmental and marine biology from Millersville University, PA, where he developed a fondness for research.  Using nothing more than a few PVC pipes, zip ties, petri dishes and maybe some duct-tape he studied population dynamics of zooplankton in a small pond focusing mainly on the freshwater cnidarian Hydra.  Spending a lot of time using a microscope, Kevin decided to switch the focus of his studies to microbiology and began studying pathogenic bacteria. He earned a MS in biology from American University, DC, while researching the effects of low-dose antibiotics on MRSA biofilms under Jeffrey Kaplan’s mentorship.  Kevin’s current research interests focus on the regulation of virulence in microbes and how that relates to biofilm formation and antibiotic resistance, focused on Staphylococcus in Shaun Brinsmade's lab.

Congratulations to Kevin for the successful defense of his dissertation!
