Vijay Singh is a statistical physicist interested in Physics of Living Systems. Vijay joined A&T Physics in August 2019. He has a BS in Physics from St. Stephens College, Delhi University, India, and an MS in Physics from Indian Institute of Technology, Kanpur, India. He got his Ph.D. in Physics from Emory University, Atlanta, USA. He was an independent postdoctoral fellow at the Computational Neuroscience Initiative (CNI) at the University of Pennsylvania, Philadelphia.

Research Interests

Vijay studies information processing in biological systems using theoretical and computational approaches. He is currently interested in identifying the principles behind processing of complex mixtures in cellular and olfactory systems. He also works on visual signal processing and is currently focusing on human color perception using computational and psychophysics methods. In the past, he has worked on phase transitions in complex hierarchical networks. His work is funded by NSF-BCS-2054900 and NIH-SC2GM140945.
