Overview

Our expertise is in the microfabrication technology and in microfluidics. We are interested in developing fabrication and integration processes for new materials in microdevices. We are also interested in developing components such as micropumps, microvalves, micromixers and microfluidic nozzles that could be used in a number of applications. We apply this expertise to build innovative micro and nanoscale devices for use in environmental and medical diagnostics, drug discovery, drug delivery and as artificial organs.

He then obtained his M.S and Ph.D in electrical engineering (2002) from University of Michigan, Ann Arbor. He was a postdoctoral fellow at Sandia National Laboratories from 2003-2004 and joined McMaster University in 2005. His research interests are in the development of microfluidic devices for drug discovery, drug delivery, diagnostics and artificial organs. He has more than 20 years of extensive experience in the micro/nano fabrication and microfluidics in the areas of medical and environmental diagnostics, drug delivery and drug discovery which has resulted in ~120 publications, in the top journals in the field. In addition he has published more than 60 refereed conference papers and has presented 35 invited talks at conferences, universities and other forums. His research has won a number of best paper awards and has been selected as cover articles for journals. He has written 6 invited book chapters and been issued 7 US patents related to MEMS/microfluidic devices. Three of his technologies has been licensed for commercialization and he has consulted with a number of leading companies in the field. Some of his research has been featured in scientific media such as Popular Mechanics as wells as in mainstream media such as CBC News, and in newspapers across Canada.
