Principal Investigator

Abhijeet L. Sangle

Abhijeet L. Sangle, Ph.D.

Assistant Professor

Bio: Abhijeet did his B.Tech. and M.Tech. (5-year dual degree) in Metallurgical Engineering and Materials Science with specialisation in Ceramics and Composites from IIT Bombay. After his graduation from IIT Bombay in 2011, he joined the Department of Materials Science and Metallurgy at the University of Cambridge for his doctoral studies in Professor Judith L. MacManus-Driscoll's research group. He worked on nanostructured SrTiO3 thin films, tuning their properties for tunable high frequency devices and photoelectrochemical water splitting.

Following his doctoral studies, Abhijeet worked in Professor Sohini Kar-Narayan's group, researching aerosol-jet printed flexible thermoelectric films for energy harvesting and temperature sensing applications. He developed bespoke inks of various thermoelectric materials.

Later, Abhijeet returned to India and in 2018 joined Applied Materials India Pvt. Ltd. in the CTO office to work on developing large area deposition of piezoelectric films. Following his over three-year stint at Applied Materials India, he joined IIT Goa as an Assistant Professor in April 2021.

Abhijeet returned to his alma mater, IIT Bombay, in March 2022, as an Assistant Professor and has since been working in this role. He is interested in developing nanostructured thin films of functional materials using the techniques of pulsed laser deposition and sputter deposition. He is working on various VAN thin films for various electronic applications such as ferroelectric memories, energy storage devices, piezoelectric/thermoelectric sensors and energy harvesters. Additionally, he is working on developing printed electronic devices from the inks of functional materials such as thermoelectrics.

In his spare time, Abhijeet enjoys listening to music, watching movies and playing badminton.
