Sean joined the EDC in 2008 to study the design process of medical devices with Dr. Digby Symons. He is interested in applying big picture design concepts as well as developing individual products in the medical devices field. One focus area is using engineering approaches such as computational fluid dynamics (CFD) to model passive dry powder inhaler (DPI) drug break-up and delivery mechanisms, in order to expedite design cycles and increase efficiency.
After receiving a Bachelor of Science in Biomedical Engineering from Johns Hopkins, Sean worked for the U.S. FDA's CDRH Office of Science and Engineering Laboratories to investigate hemolysis (blood damage) in blood flow devices with Dr. Richard Malinauskas. Sean earned a Master of Philosophy in Engineering degree from Cambridge in 2007 for his work on the artificial heart pump project with Dr. Richard McMahon. For his Master's thesis, he designed a human circulatory system analogue for in vitro testing of heart pumps.
In 2009, Sean was awarded a FDA Medical Device Fellowship Program grant to investigate the early detection of medical device adverse events during device postmarket surveillance at the USFDA CDRH Office of Surveillance and Biometrics.
Sean has supervised for the following undergraduate module:
-3G2 Mathematical Physiology
Sean has demonstrated for the following undergraduate modules:
-4A2 Computational Fluid Dynamics
-3G2 Mathematical Physiology - Speech Production Lab
-1A Drawing and CAD
Sean's research is supported by the EDC, the Whitaker International Fellows and Scholars Program, and the Clare Hall Mellon Bursary. He is a member of Clare Hall college, where he served as the Graduate Student Body (MCR) President in 2008.
