I am currently a Postdoctoral Scholar at University of California, San Diego working with Prof. Joseph Wang on wearable sensors. Previously I was a PhD student in the Department of Chemical and Biomolecular Engineering at North Carolina State University working under Dr. Orlin Velev, Dr. Michael Dickey and Dr. Michael Daniele. My main area of research lied in developing a non-invasive, long term, self powered, osmotically driven wearable paper microfluidic sweat sampling platform that can function under low sweating conditions without requirement of any active perspiration. Our technology can also be combined with microneedles for ISF (interstitial fluid) sampling and glucose analysis. This research was funded by ASSIST (Advanced Self-Powered Systems of Integrated Sensors and Technologies) , which is a National Science Foundation sponsored Nanosystems Engineering Research Center (NERC) center at NC State since 2012.
