This image is a typical microfluidic channel used in Pennathur Lab. Chemical and biological analytes are electrokinetically driven through the channel, and by monitoring the flow, information about the analytes (such as charge, size, and zeta potential) can be deduced.
The research in the Pennathur Laboratory is focused on novel studies of chemical and biological species using fabricated micro- and nanoscale devices. The scope of the research program is broad, spanning the fields of Physics, Biology, Chemistry, and Engineering. The research goals are also broad, focusing on the fundamental science of nanoscale systems, while also exploring exciting technological possibilities. Major efforts include, general electrokinetics, creating and developing enabling micro- and nanofluidic tools to identify and characterize chemical and biological compounds, improving current bionalaytical devices, and designing/engineering entire systems for point-of-care usage.
Pennathur began at UCSB in the Mechanical Engineering department in July 2007. Her research group focuses on using fundamental fluidics knowledge at both micro- and nano -scales to create novel devices for practical applications. Prior to coming to UCSB, Pennathur taught at University of Twente and held multiple positions at various companies and schools such as Sandia National Laboratories, Stanford University, National Institute of Standards and Technology, Tigris Corporation, Lockheed Martin, and MIT. She is the co-author of one textbook and general audience textbook on Nanotechnology, and has won multiple awards including the DARPA Young Faculty award and the PECASE (Presidential Early Career Award for Science and Engineers).
