Charlie Clark is a Ph.D. candidate studying under Professor James Landers, whose lab is dedicated to addressing clinical and forensic needs through microfluidics and bioanalytical chemistry. Charlie’s primary research encompasses acoustic separation of sperm cells from sexual assault samples, with the goal of expediting the DNA profiling process for human identification. This work has resulted in field-testing of prototype instrumentation, and Charlie continues to address challenges regarding sample composition and feedback monitoring of the acoustic trapping process. Charlie’s research has received support from the National Institute of Justice, as well as multiple government-run forensic biology labs, and has the potential to significantly reduce the current backlog of sexual assault samples that await DNA testing. Charlie received his M.S. in chemistry with a minor in biochemistry at the College of William and Mary. At U.Va., Charlie was awarded the Outstanding Graduate Teaching Assistant Award, the Dr. Frank Finger Graduate Fellowship for Teaching, and won first place in the 2018 Three Minute Thesis Competition.
