Kunal Mukherjee
Assistant Professor of Materials Science and Engineering
BioKunal Mukherjee is an assistant professor in Materials Science and Engineering at Stanford. He has been an assistant professor in the Materials department at UC Santa Barbara (2016-2020), held postdoctoral appointments at IBM TJ Watson Research Center (2016) and MIT (2015), and worked as a transceiver engineer at Finisar (2009-2010).
The Mukherjee group specializes in semiconductors that emit and detect light in the infrared. Our research enables better materials for data transmission, sensing, manufacturing, and environmental monitoring. We make high-quality thin films with IV-VI (PbSnSe) and III-V (GaAs-InAs/GaSb) material systems and spend much of our time understanding how imperfections in the crystalline structure such as dislocations and point defects impact their electronic and optical properties. This holds the key to directly integrating these semiconductors with silicon and germanium substrates for new hybrid circuits that combine infrared photonics and conventional electronics. -

Physical Science Research Scientist, Psychology
Current Research and Scholarly InterestsDr. Vaidehi Natu is a developmental neuroscientist. Her research program aims to study how the human brain matures from infancy to adulthood, as it acquires new life skills and behaviors: What are the origins of the cellular and molecular mechanisms of brain development during infancy? How does the trajectory of neural mechanisms unfold during development, as school-aged children acquire complex skills such as reading or face recognition? What are some of the parallels in brain development across primate species? What changes occur in the brain in developmental disorders such as autism, multiple sclerosis, and dyslexia?
She uses a multi-modal approach by combining various neuroimaging techniques including functional magnetic resonance imaging (fMRI), quantitative MRI (qMRI), and diffusion MRI (dMRI) as well as behavioral observations, histology, comparative methods across humans and macaques, and intracranial electroencephalography. Combining complementary techniques provides a unified understanding of how the brain’s anatomy, function, and behavior co-develop to achieve complex human skills. -
