Molly O’Brien

Research Interests:

Automated skill assessment from surgical tool motion data

I am a second year Ph.D. student in Computer Science working with Austin Reiter, Greg Hager, and Russ Taylor.  I work on automated skill assessment from surgical tool motion data. My current project focuses on skill assessment for Septoplasty data using Machine Learning and Deep Network approaches.  Specifically I am continuing work in our lab that identifies “strokes” in the surgical data and determines the surgeon’s skill using statistics from these strokes. I am also using Convolutional Neural Networks (CNNs) to identify the surgeon’s skill from a fixed window of tool motion data. The goal for this work is to 1) identify the surgeon’s skill, and 2) give interpretable feedback to trainee surgeons.
