Trevor Cohen, MBChB, PhD

Associate Professor

A native of South Africa, Dr. Cohen practiced medicine in a rural hospital setting in his home country. When dealing with patients with mental illness or behavioral issues, Cohen often found that essential patient information was not available when needed. This issue, along with a longstanding interest in computer technology, led Cohen to leave medicine and pursue a new career in informatics. Cohen’s research interests focus on distributional semantics, which involves using computers learn how things are related from electronic text. He is also interested in the thought processes of clinicians that relate to the commission of, and recovery from, medical errors. Cohen works in the SBMI facility for the National Center for Cognitive Informatics and Decision Making in Health Care. He joined the SBMI in 2009, after teaching at Arizona State University.
