Seeking superhuman explanations

I'm a staff research scientist at Voyage AI, working on training large embedding models. Before that, I spent ~4 lovely years at Microsoft Research (Deep learning group) using LLMs to build & interpret healthcare data, brain models, and LLMs themselves. I completed my PhD with the brilliant Bin Yu in 2022, working on AI interpretability.

Research

Some recent work I'm excited about! I put a lot of my code into the imodels & imodelsX packages.
๐Ÿ” Interpretability methods, especially LLM interpretability.

Augmented imodels - build a transparent model using LLMs
Agentic imodels - evolve agent-facing interpretability tools via autoresearch
Attention steering - mechanistically guide LLMs by emphasizing specific input spans
Explanation penalization - regularize explanations to align models with prior knowledge
๐Ÿ’Š Clinical decision rules,ย can we improve them with data?

Human-AI co-design of clinical models - build clinical rules by using LLMs to analyze EHR, vetted by clinicians
Greedy tree sums - build accurate, compact tree-based clinical models
MINT - forecast EHR with a minute-scale foundation model
Clinical rule bias assessment - evaluate biases in popular clinical decision instruments
๐Ÿง  Semantic brain mapping, mostly using fMRI responses to language.

Generative causal testing - causally test fMRI explanations with LLM-generated stimuli
QA encoding models - model fMRI language responses to verbal theories using LLM annotations
Summarize & score explanations - generate natural-language explanations of fMRI encoding models
