Research

Some areas I'm currently excited about. If you want to chat about research or are interested in interning at MSR, feel free to reach out over email :)

🔎 Interpretability. I'm interested in rethinking interpretability in the context of LLMs

augmented imodels - use LLMs to build a transparent model
explanation penalization - regularize explanations to align models with prior knowledge
adaptive wavelet distillation - replace neural nets with simple, performant wavelet models

🚗 LLM steering. Interpretability tools can provide ways to better guide and use LLMs (without needing gradients!)

tree prompting - improve black-box few-shot text classification with decision trees
attention steering - guide LLMs by emphasizing specific input spans
interpretable autoprompting - automatically find fluent natural-language prompts

🧠 Neuroscience. Since joining MSR, I've been focused on leveraging LLM interpretability to understand how the human brain represents language (using fMRI in collaboration with the Huth lab at UT Austin).

explanation-mediated validation - build and test fMRI explanations using LLM-generated stimuli
qa embeddings - build interpretable fMRI encoding models by asking yes/no questions to LLMs
summarize & score explanations - generate natural-language explanations of fMRI encoding models

💊 Healthcare. I'm also actively working on how we can improve clinical decision instruments by using the information contained across various sources in the medical literature (in collaboration with Aaron Kornblith at UCSF and the MSR Health Futures team).

clinical self-verification - self-verification improves performance and interpretability of clinical information extraction
clinical rule vetting - stress testing a clinical decision instrument performance for intra-abdominal injury

Across these areas, I'm interested in decision trees and how we can build flexible but accurate transparent models. I put a lot of my code into the imodels and imodelsX packages.
