Faculty Profile: Prof. Alex Lew — Yale CS

Position: Assistant Professor (joining Fall 2025) Institution: Yale University, Department of Computer Science Lab: Probabilistic and Differentiable Programming at Yale Report date: 2026-06-12


Research Focus

Probabilistic programming, Bayesian inference automation, LLM controlled generation/sampling. Member of GenLM consortium (multi-university): improving controllability, composability, and interpretability of language models via probabilistic programming and Bayesian inference.

Academic Profile

  • PhD: MIT CSAIL
  • POPL Distinguished Paper, LICS Distinguished Paper
  • COLM Outstanding Paper (LLM inference acceleration via sequential Monte Carlo steering)
  • Facebook Research Award
  • Joining Yale Fall 2025 — lab is brand new, no student placement data

Fit with Weijia Zhang

DimensionAssessment
LLM agents / agentic AI❌ Not primary focus
Post-training (SFT / RL)❌ Not his area
RAG / retrieval❌ No
LLM inference / controlled generation✅ Adjacent (SMC steering of LLMs at COLM)
VLM / GUI agents❌ No

Verdict

Low relevance for Weijia’s core interests (SFT, RL, agentic AI). His work is primarily theoretical probabilistic programming with some LLM inference applications. Lab is brand new — no placement data. Not a recommended advisor or committee member for Weijia’s goals.
