Travis Sawyer, PhD

Biography

Dr. Travis Sawyer received his Bachelor's Degree in Optical Sciences and Engineering from the University of Arizona before pursuing an MPhil in Physics at the University of Cambridge in the UK supported by a Churchill Scholarship. He then returned to the University of Arizona as a National Science Foundation Graduate Research Fellow to complete his PhD in Optical Sciences, focused on ovarian cancer screening. He started his laboratory immediately after completing his doctoral training, where his team focuses on developing optical imaging technologies to inform diagnosis and management of cancer.

Cancer Focus

One of Dr. Sawyer's primary research focuses is using optical imaging for improved screening of gastrointestinal cancers including gastric and esophageal cancer. He is particualrly interested in developing technology that is accessible to underrepresented communities. Another research focus of his is developing surgical localization tools for pancreatic cancer resection. He also has broad interest in using optical imaging to better understand the causatic mechanisms of disease through advanced microscopy.
