Sayak Dutta Gupta

Sayak, born and brought-up in Kolkata, is presently a DST INSPIRE Research Fellow in DESE, IISc Bangalore. His primary research interest involves development of reliable normally-OFF GaN HEMTs for power applications. His work involves design, fabrication and characterization of e-mode HEMTs with a view to develop reliable gate oxides.

Sayak obtained his bachelor’s degree in Electronics and Communication Engineering from Institute of Engineering and Management (IEM) Kolkata in 2014, post which he did his master’s in Materials Science and Engineering from Indian Institute of Engineering Science and Technology (IIEST) Shibpur in 2016. During his master’s, he worked on silicon nanoparticles-polyaniline nano-composites for optoelectronic and thermoelectric applications, a collaborative work of IIEST Shibpur and UGC-DAE CSR, Kolkata centre. He also worked in MSDLab, IISc Bangalore as a project assistant for a year before joining the doctoral program. Sayak enjoys cooking, swimming and is an ardent gallivanter.
