Stephen Pfohl

I am a PhD student in Biomedical Informatics at Stanford, advised by Nigam Shah. My work broadly focuses on the use of machine learning to guide clinical decision making. Recently, I have focused on understanding how to design such systems to be fair and robust. Before coming to Stanford, I worked with Cassie Mitchell at Georgia Tech on developing models of disease progression in Amyotrophic Lateral Sclerosis. In the summer of 2019, I was a research intern at Google Health.
