I am an AI researcher and engineer with a track record spanning healthcare AI, computational neuroscience, embodied intelligence, and AI-driven manufacturing, deploying machine learning across high-stakes healthcare, industrial, and research settings, and currently working at the frontier of world model learning. Along the way I've worked directly with clinicians, hospital leadership, government funders, startups, CROs (Contract Research Organizations), and non-profits, translating stakeholder needs into AI systems deployed across manufacturing, neuroscience, and healthcare.
Over the past three years I built medication-recommendation and precision-health pipelines for neurodivergent populations at Holland Bloorview Kids Rehabilitation Hospital, then deployed regulatory-compliant, EHR-integrated ML in production at Waypoint Centre for Mental Health Care. I now bring that same rigor to embodied intelligence research as a Research Associate at SUTD (Singapore University of Technology and Design).
At SUTD, my research builds AI pipelines for real-time estimation of learners' internal world models from motion-capture kinematic data, modelling movement exploration as a Markov Decision Process, running Bayesian inverse RL to recover reward structure and state-transition dynamics, and using inferred world models to scaffold open-ended embodied creativity in real time. This work connects foundational questions in world model learning and generative modelling to the physical, embodied setting.
Career timeline
Looking ahead, I want to extend this embodied AI work toward robot learning, robot foundation models, and world model architectures that generalize across tasks and embodiments. My interpretability background also points toward a direction I care about deeply: AI safety and security. Building evaluation frameworks for explanation faithfulness under DARPA/AFRL gave me a concrete foothold in mechanistic interpretability of LLMs, understanding what circuits and features actually encode rather than just what outputs look like, and I want to bring that same rigor to trustworthy, verifiable AI systems.
Research interests
My work runs along two tracks that share a common thread: rigorous modeling of behavior and reward under uncertainty, whether the agent is a robot or a clinical care pathway.
Current research at SUTD (Singapore University of Technology and Design) on real-time world model estimation from motion-capture data and Bayesian inverse RL-driven scaffolding of embodied creativity, pointed toward robot learning and robot foundation models.
Three years of production-facing clinical AI: deploying AI systems in pediatric care at Holland Bloorview Kids Rehabilitation Hospital, followed by regulatory-compliant, EHR-integrated ML deployment at Waypoint Centre for Mental Health Care.
Throughline The connective thread is interpretability. Building evaluation frameworks for explanation faithfulness under DARPA (Defense Advanced Research Projects Agency) / AFRL (Air Force Research Laboratory) gave me a concrete foothold in mechanistic interpretability of LLMs, and years of clinical deployment gave me a grounded sense of what "trustworthy" actually has to mean when the stakes are real.
