DEEP LEARNING & COMPUTATIONAL NEUROSCIENCE
Srajan Agarwal
I’m a Data Science student at IISER Thiruvananthapuram working at the intersection of deep learning and computational neuroscience.
My research focuses on graph representation learning applied to brain networks. I explore how structural and functional connectivity govern neural information passing to support cognitive function, aiming to discover robust computational biomarkers for neurological diseases.
