I build machine-learning and computer-vision pipelines that turn ordinary video into quantitative motor biomarkers — detecting and classifying gait abnormality in cerebral palsy, grounded in clinical biomechanics.

About

Who I am

I work at the seam between clinical biomechanics and brain-inspired machine learning.

An MS researcher in Medical Science and Technology at IIT Madras, in the Computational Neuroscience Lab under Prof. V. Srinivas Chakravarthy. My research extracts biomechanical motor biomarkers from video — knee asymmetry, trunk lean, pelvis sway — and uses them to detect and classify gait abnormality in children with cerebral palsy.

The throughline across everything I build is one clean pipeline: raw movement → pose → signal → decision, with oscillator-based neural networks (DONN / ResHopf) as a recurring tool.

Objectives

  • Develop machine-learning and computer-vision systems for clinical movement analysis and neurological disorders.
  • Advance video-based motor-biomarker extraction and gait-abnormality classification for pediatric cerebral palsy.
