🌱 My main postdoc projects are:- Measuring consumption of opiods following surgery, and reducing overprescribing through prescription guidelines and provider interventions.
- Deep learning for surgical videos and operative notes to evaluate surgical skill and risk of complications.
-
✨ My three dissertation projects are:- Constructing interval variables via faceted Rasch measurement and multitask deep learning, applied to hate speech
- A new targeted learning method for causal inference of multiple treatments (mixtures), applied to chemical exposures
- A nested ensemble clinical model for heart attack risk prediction in electronic health records
