Professor Deblina Sarkar leads a research group at the MIT Media Lab developing microscopic technologies that work inside the human body. Her team creates ultra-small sensors and antennas, with some able to operate inside cells, to help detect disease early and enable low-power, smart health devices. This work blends biology, electronics, and AI, and has powerful implications for women’s health, where conditions are often underdiagnosed. Professor Sarkar explains how these nascent technologies are enabling earlier detection and more personalized care with Carol Massar and David Gura on Bloomberg Businessweek Daily.
