Ashis research group at IIT Madras works on the fundamentals and applications of microfluidics. The group takes a 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 and droplets in microchannels, interaction of acoustics, electric field and magnetic field with fluid interfaces and particles, capillarity and wetting.
The group is equally committed towards developing microfluidic platforms and lab on chip technologies mainly for healthcare applications. The team has been working on developing a rapid and sensitive opto-microfluidic platform for detection of dengue antigens in blood. The group is also developing a generic microfluidic platform for continuous and real-time monitoring of gasotransmitters in blood. The group is striving to develop a microfluidic platform isolation and genomic profiling of CTCs.
