Machine Learning Systems, Alignment, and Evaluation

I am a research-oriented machine learning systems engineer working on foundation model infrastructure, alignment, and evaluation. I build efficient and reliable systems for large language models while studying the algorithms and data choices that make them more useful, controllable, and cost-effective in real applications.

  • 🧐 My central research interest is model-system co-design: understanding how model architecture, inference algorithms, data curation, hardware utilization, scheduling, and distributed runtimes interact.
  • 💼 I work on Model-as-a-Service platforms and high-performance LLM inference, developing production serving infrastructure with vLLM and SGLang.
  • 🎓 My recent research includes distributed disaggregated inference, preference optimization, instruction-tuning data selection, multimodal evaluation.
  • 🌱 I investigate alignment and evaluation methods that connect measurable model behavior with real-world usefulness, controllability, reliability, and serving cost.
  • 📚 My systems work spans model runtime integration, scheduling and continuous batching, KV-cache and memory management, distributed execution, observability, and reliability.
  • ⛵ I am interested in collaborating on open research and infrastructure that make frontier AI systems faster to experiment with, more rigorous to evaluate, and dependable at scale.
  • ✍🏻 I share technical writing on machine learning systems, infrastructure, and software engineering through my personal blog.
