MS by Research, IIT Madras · advised by V. Srinivasa Chakravarthy
Previously AI Engineer & Researcher at Neurogati
I work on representations that carry structure — dynamics, prediction, geometry — rather than capacity alone. Right now that mostly means oscillators: models of neural computation where the dynamics, not the weights alone, carry the representation, tested against EEG and fMRI responses to naturalistic stimuli. The applied side is clinical — Parkinson's biomarkers from video, audio, and gait, and markerless 3D pose running in a physiotherapy clinic.

Jun 2025 — Jun 2026
Founding engineer on the AI team, building clinical measurement systems from research prototype through to deployment in partner clinics.
QuamonPD — a digital biomarker platform for Parkinson's disease that quantifies motor and speech symptoms from phone video and audio. Built the vision and audio pipelines and the local-first mobile capture architecture for use in clinical settings with unreliable connectivity.
StereoPose3D — markerless 3D motion capture for physiotherapy, recovering metric joint positions from a calibrated stereo camera pair. Deployed and in ongoing use at a partner clinic.
Spatial navigation and memory — extended the grid-world graph work into a scene-graph memory system, pairing a Neo4j graph store with vision-language models so an agent could answer questions about an environment it had explored.
IIT Madras
May — Jul 2024
Developed a system that uses Graph Database, Graph Neural Networks and Large Language Models(LLMs) to navigate a grid world, answer user queries, and provide relevant information about the environment.
Processed the dataset to store it in a Neo4j graph database and for other downstream tasks.
Used the LLM(Llama3) to question the graph database and generate Cypher queries for the questions asked by the user. The prompts were dynamically tuned using Langchain to improve query generation.
Implemented Q-learning method to explore the grid world. Used the explored data to query the graph neural network using the LLM(Llama3).
Presented this work at the 5th Annual Research Showcase, IIT Madras.

Tools & Domains
Outside the Lab
Mostly available light: architecture, long exposures, cities at hours when they aren't performing. The discipline is subtraction — deciding what stays out of frame.
Blender and Unreal. Modelling and lighting a scene is the one place I think spatially instead of symbolically, which turns out to transfer more often than expected.
Pencil, ink, tablet. Mostly figures and linework. It's the slowest feedback loop I have, and the only one I can't debug my way out of.
Classically trained pianist, Trinity Grade 8, working in orchestration and Carnatic music. Most of what I understand about frequency, resonance, and phase I met here before I met it in a paper.
