Our group uses microfluidic technology to build point-of-care diagnostic platforms and to address certain problems at the physics/biology interface. We work with both traditional microfluidic devices and alternate substrates like paper and fabric to develop affordable lab-on-a-chip platforms. Some of our translational projects include developing a DNA-based screening platform for tuberculosis, detection of sickle cells in blood and building a portable cell sorter using the principles of deformability cytometry. We are also interested in understanding how mammalian and bacterial cells respond to their physical environments. Microfluidics allows us to modulate the local environments of cells both spatially and temporally. Our translational projects are funded by the Department of Biotechnology (Govt. of India), the Bill and Melinda Gates Foundation, the Tata Centre for Technology and Innovation, IIT Bombay, and the Wadhwani Research Center for Bioengineering, IIT Bombay.
