Dr. Chaitanya Nutakki, received his Ph.D. in computational neuroscience from Amrita School of Biotechnology. His research has primarily focused on mathematical modeling of neurovascular coupling and reconstructing fMRI BOLD signals from the cerebellum and interconnected circuits. This work led to the development of a tool called BOLDsim, which is part of the Human Brain Project. Additionally, Dr. Nutakki is actively engaged in a DST-funded project, where he contributes to the design and development of a low-cost wearable device for analyzing human gait. Also, worked in EU-funded WeNet project will develop the technology to empower deeper social interactions through diversity-aware AI.
