Ben Hawkins currently works on dielectrophoretic particle manipulation. Specifically, on developing dielectrophoresis-based high-throughput screening techniques for phenotypic variation in cell membrane composition in Mycobacteria.

More generally, Ben's interests lie in the development of integrated microfluidic systems and biological applications. As microfluidic techniques mature, with a wide range of proven assays and applications, the development of robust, repeatable fabrication and integration techniques will be needed in order to bring the advantages of microfluidic technology into common laboratory practice.


Biography

Ben Hawkins joined the Micro/Nanofluidics Laboratory in October of 2005. From 2000-2005, Ben studied Electrical Engineering at California State University, Fresno. While studying, he developed a loosely coupled inductive power transfer system for battery charging as part of the Bulldog Bot autonomous vehicle project. In 2004, Ben started consulting, working for Signet Systems -- with high-frequency battery charging systems -- and Biomimetic Connections -- examining biological systems and their applicability to engineering problems.

While working at Cornell, Ben has worked on electroosmotic pumping techniques for analyte delivery, continuous flow dielectrophoretic particle separation techniques, theoretical and experimental characterization of bacterial dielectric properties, and numeric simulation of electrothermal flow phenomena.

Ben is a member of the Cornell Biomedical Engineering Society, American Institute of Chemical Engineers, American Society of Mechanical Engineers, Tau Beta Pi, Eta Kappa Nu, IEEE, and Phi Kappa Phi.


Current Projects

Current projects include the development of rapid particle sorting systems using insulative dielectorphoresis and electrode-based dielectrophoretic mobility assays.
