Michael Shopshire, Ph.D.

Michael Shopshire is a substance abuse treatment researcher at the University of California, San Francisco (UCSF) Department of Psychiatry. He started working at UCSF while he was working on his Ph.D. in Psychology at the University of California, Berkeley and decided to stay at UCSF. As an undergraduate at the University of

Southern California, he spent most of his effort preparing to study clinical psychology rather than enjoying the study of statistics. Statistics was not his favorite subject and he viewed it as merely something he had to endure to become a psychologist. But his first part-time teaching offer was to teach Introductory Statistics, and so he spent his spare time learning how to teach statistics, and discovered that statistics could be fun.

He has taught statistics part time for the past 20 years throughout the Bay Area, and hopes that he shows his students that statistics is fun.
