Ashis research group at IIT Madras works on the fundamentals and applications of microfluidics. The group takes great deal of interest in the identification and demonstration of unique and interesting microscale phenomena. The team is focused on unraveling the underlying mechanisms and developing understanding of such phenomena. Moreover, effort is put towards exploiting these phenomena for the development of technologies for various applications. The group’s fundamental research activities falls in the broad areas of behavior of particles at fluid-fluid interface, interaction of acoustics, electric field and magnetic field with fluid interfaces, capillarity, wetting and elastocapillarity.
The group is equally committed towards developing microfluidic platforms and lab on chip technologies for healthcare and other related applications. The team has been working on developing low-cost and portable blood-plasma separation devices and an optofluidic platform for identification and isolation of rare cells in single-cell format. The group is striving to develop microfluidic platforms for early diagnosis of sepsis, isolation and genomic profiling of CTCs and rapid detection of dengue.
We may have Post-Doc and Project/Research Associate positions open in the area of microfluidics, if interested please send your CV and arrange to send two reference letters to Email: firstname.lastname@example.org
