Experience
-
2026 - 2026 Research Intern — RL for LLM reasoning
IBM Research
- Ran ablations and reproductions of existing self-distillation pipelines and uncovered failure modes of OPSD and SDPO.
- Ran a prefix-advantage study across Qwen3-1.7B/4B/8B characterizing where privileged-teacher signal localizes in a rollout. Submitted to the NeurIPS 2026 workshop on Transitioning from Pre-Training to Post-Training.
- Investigating other uses of distillation — whether privileged information can be used in a helpful, non-cheating way.
-
2025 - 2026 Cambridge, MA
Researcher — RL for generative models
MIT-IBM Watson AI Lab
- Investigated RL fine-tuning of flow models for molecule and crystal generation.
- Co-author on Tailored primitive initialization is the secret key to reinforcement learning (ACL 2026); built the embedding-similarity pipeline used for the paper’s diversity analysis, showing Tailor’s warm-start data is more reasoning-diverse than the Standard-CoT and 4-STaR baselines.
-
2026 - 2026 New York, NY
WITTI Wintern — quantitative finance
Hudson River Trading
-
2025 - 2025 Software Engineering Intern — multi-agent systems
Talkdesk
- Prototyped agentic user memory for a multi-agent system and a multi-agent evaluation framework for a production RAG pipeline.
-
2024 - 2025 Cambridge, MA
Researcher — AI security & agents
MIT Media Lab
- Built attestation for AI agents negotiating inside GPU-backed trusted execution environments; wrote circom circuits producing zkSNARK proofs that the negotiation ran as specified.
- Built tool-using agents (Gmail, Google Calendar, Shopify APIs) and an evaluation harness for multi-agent negotiation.
-
2025 - 2025 Cambridge, MA
Researcher — generative AI for design
MIT DeCoDE Lab
- Built the sketch-to-3D retrieval pipeline (2D sketch → nearest 3D car mesh) and benchmarked retrieval models and similarity metrics; co-author on the resulting ASME IDETC-CIE 2025 paper.
-
2023 - 2024 Researcher — network science
MIT PRIMES-USA
- Proposed and evaluated an algorithm combining path-based link prediction with influence-maximization heuristics to identify future vital nodes in weighted collaboration networks.
- Introduced RA-2 and quasi-local RA-2, new link-prediction similarity metrics; built the simulation and evaluation pipeline (7 link-prediction metrics × 12 centrality measures × 8 selection algorithms, under simple and complex contagion); wrote the initial manuscript.
- Co-author (alphabetical order) on papers in Physica A (2026) and on arXiv (2024).
