Dr. Dipjyoti Das is a native of Abhayapuri, popularly known as the “Devodaru Nagari,” situated in the Bongaigaon district of Assam. He completed his Bachelor of Engineering from Assam Engineering College and pursued his Ph.D. from IIT Guwahati. His doctoral research focused on solution-processed OLEDs for solid-state lighting.
Following his Ph.D., Dr. Dipjyoti Das worked as a postdoctoral researcher at KAIST, South Korea, where he began working on ferroelectric memories and energy storage capacitors. He later moved to Georgia Institute of Technology as a postdoctoral fellow, focusing on FeFETs and ferroelectric flash memory technologies. After his tenure at Georgia Tech, he joined NIT Silchar as an Assistant Professor, where he continued his research and academic activities in semiconductor devices and emerging memory technologies.
Dr. Dipjyoti Das has received several prestigious recognitions and awards, including the BK21PLUS Fellowship, the IEDM 2023 Highlight Paper recognition, and the Haedong Best Paper Award (Academic Category) in 2024. He also received the Certificate of Proficiency from the Assam Higher Secondary Education Council in 2007 and the Anundoram Borooah Award from the Government of Assam in 2005.
