Professional Summary

First-author paper at a NeurIPS 2026 workshop Sole-author ICLR 2027 submission Founding team, a16z AI startup

Experience

  • 2026 - Present

    Remote

    RL Intern (Founding Team)
    Delightful AI (a16z speedrun-backed)
    • Built bioinformatics agent RL environments (Chimera) end to end that hold GPT-6 Astra, Claude Opus 5.5, and Fable 5.1 to <0.5/1.0 reward: a synthetic generator of verified-solvable tasks, Docker/Harbor execution, and reward grading.
    • Sped up task generation 6x by adding caching and parallelism to the generator pipeline.
    • Analyzed agent trajectories with an LLM-as-a-judge that checks each run against expected milestones.
  • 2026 - Present

    Urbana, IL

    Undergraduate Researcher
    BLENDER Lab, UIUC (with Alexi Gladstone)
    • Led research extending Energy-Based Transformers to multi-token prediction through Explorative Modeling (XM).
    • Implemented the full training stack and compared candidate energy formulations against block-diffusion LLMs.
  • 2026 - Present

    Remote

    ML Research Contributor
    MedARC
    • Drove 37% of the gain over baseline on NanoPath v1 (26% on v2) by building an LLM autoresearch agent with dual-branch search and anti-overfitting cycles (3rd-author paper, accepted at a NeurIPS 2026 workshop).
    • Cut config errors 80% and token use 15x by designing agent infrastructure (knowledge graphs, SLURM, worktree isolation).
    • Raised mean PathoROB robustness 0.726 to 0.891 and improved downstream AUC across 7 pathology foundation models by introducing SPECTRA, label-free contrastive LoRA fine-tuning (first-author paper, accepted at a NeurIPS 2026 workshop).
  • 2024 - 2026

    New York, NY

    Pathology AI Research Intern
    AI in Medicine & Computational Biology Lab, Weill Cornell Medicine
    • Found that error doubles out of distribution (MAE ~0.10 to ~0.20) by benchmarking 12 vision foundation models for tumor-purity regression on TCGA and internal cohorts in PyTorch.
  • 2024 - 2026

    New York, NY

    Computational Oncology Research Intern
    Advanced Computing & Oncology Lab, Memorial Sloan Kettering
    • Engineered a CPU-only LLM pipeline that classified 370 clinically annotated lung-cancer CT reports, optimizing prompts for Llama 3.1-8B and Qwen3-4B with DSPy MIPROv2 (3rd-author abstract, accepted at ACRO 2026).
    • Applied Cox regression and survival analysis to 230 patients’ clinical and demographic records to identify correlations between percent thymic tissue and NSCLC outcomes.
  • 2025 - 2026

    Stony Brook, NY

    Simons Summer Research Fellow (Computational Genomics)
    Yurovsky Lab, Stony Brook University (Simons Foundation)
    • Predicted survival of 185 glioblastoma patients with a DNABERT-based Cox model on non-coding DNA mutations.
    • Identified significant age-related survival signals and racial disparities in mutational scores.

Projects

  • Which State Should Prediction Read?

    August 2026 - September 2026 Sole-author paper, under review at ICLR 2027
    • Trained State–Prediction Separation (SPS) LMs, which split a Transformer into separate state and prediction streams; ablations showed the two divide the work: state tracks context, prediction retrieves from it.
    • Reached a FLOP-matched Transformer’s loss on 2.1x fewer tokens and ended 0.064 nats/token lower after 20B tokens by designing Sequential, a final-state-read architecture, from these ablations (92M non-embedding params).
  • Qwen3.6-27B ExpThink

    July 2026 - August 2026 LLM Post-Training, GRPO
    • Cut thinking tokens 52% in-domain / 34% OOD and truncation 6.0% to 2.6% while mean OOD accuracy rose 84% to 86% by post-training Qwen3.6-27B with a length-adjusted GRPO reward.
    • Trained with PyTorch FSDP on 8xH100 in verl, with rollouts from tensor-parallel SGLang.
  • speedLM

    July 2026 - August 2026 OpenAI-Compatible LLM Serving, Speculative Decoding
    • Built a custom vLLM server that fine-tunes EAGLE-3 draft models on captured local traffic during idle GPU time.
    • Raised tokens accepted per verification step 13.4% over the stock draft on held-out Qwen3-8B data.
  • micro-DINOv3

    February 2026 - April 2026 Pure Python, Computer Vision
    • Implemented DINOv3 in dependency-free Python with hand-written reverse-mode autograd and a ViT, EMA teacher-student distillation, DINO + iBOT objectives, KoLeo regularization, axial RoPE with register tokens, and Gram anchoring.
  • DeepMoE Reproduction

    July 2024 - November 2024 PyTorch, Computer Vision
    • Recreated the main CIFAR-10 results of “Deep Mixture of Experts via Shallow Embedding” (100+ citations) in PyTorch, recovering its accuracy-vs-compute tradeoff.
    • Identified a gate-scaling failure that destabilizes training at the paper’s learning rate.
