Postdoctoral Researcher

Background

Received PhD in 2017 from Indian Institute of Technology-Madras (IIT-M) in the Department of Chemical Engineering and subsequently pursued postdoctoral research in rapid and low-cost diagnostic sensor development in IIT-M (2017 – 2018 and 2020 – 2023). Received Research Associate fellowship from Indian Council of Medical Research under Innovation and Translational Research Division for a period of 1.5 years (Mar 2022 to Jul 2023).

Interested in translation research which has a potential technology transfer opportunity. Research expertise includes development of smart sensor technologies for healthcare and environmental application. Worked on microfluidic paper-based analytical device (µPADs) fabrication techniques to build affordable and sensitive diagnostic kits, developing colorimetry-based sensing methodologies. Other expertise includes nanomaterial synthesis in batch and continuous flow system, material characterization, surface modification strategies and application of nanomaterials in heterogenous catalytic reaction.
