      May 2026 - Aug 2026 · 4 mos

      Researched Bayesian optimization and machine learning techniques for catalyst design in CO2 conversion. Implemented a model-based reinforcement learning framework using PPO for non-myopic Bayesian optimization. Explored non-myopic Bayesian optimization using low-fidelity rollouts to address model misspecification.

    Worked on Software Factory, creating agentic systems to redefine software creation. Built custom systems around AI agents to improve reliability and performance in agentic coding workflows. Developed 3 full-featured modules for a full-cycle SDLC platform, covering requirements tracking, project management, and QA workflows, each delivering complete end-to-end functionality across multiple features and user flows. Contributed across product and engineering by defining product requirements, writing high-level engineering blueprints, building full end-to-end features, and shipping improvements throughout the codebase.

    Sep 2025 - Mar 2026 · 7 mos

    Co-authored “DermArt: A Human-Annotated Dataset and Contrastive Distillation Framework for Artifact-Robust Dermatological AI,” submitted to MICCAI 2026 (second author). Contributed to developing a contrastive distillation framework integrating contrastive representation learning and self-distillation to improve skin cancer diagnosis robustness and reduce disparity between clean and artifact images. Benchmarked CLIP-based vision-language models and multimodal LLMs for zero-shot artifact annotation on the Fitzpatrick 17k dermatological dataset, evaluating model robustness across diverse artifact types.
