Osasere Evbuomwan

Assistant Professor and Faculty Director of Engineering Summer Zero Program

Full-Time Faculty
Harney Science Center, 370


Professor Evbuomwan received her BS in Chemistry with a minor in Mathematics from Lewis-Clark State College in Lewiston, Idaho in May 2006. Later that year, she joined the chemistry program at the University of Texas at Dallas where she received her PhD in Chemistry under the supervision of A. Dean Sherry. Evbuomwan spent an additional year at UT Dallas as a postdoctoral research associate after which she was selected as one of ten Madrid-MIT M+Vision Postdoctoral Research Fellows at MIT. In 2015, she began a tenure-track faculty position at Gonzaga University where she taught a variety of upper and lower division courses in Chemistry and performed research with undergraduates in the field of Biomedical Imaging.

At USF, Evbuomwan’s research endeavors are primarily focused on the development of Magnetic Resonance Imaging (MRI) and Optical Imaging agents for prostate cancer diagnosis, and image-guided tumor resection. All projects span inorganic chemistry, organic chemistry, analytical chemistry, and biomedical imaging, and introduce students to the interdisciplinary nature of research. In addition to synthesizing multi-dentate ligands and their corresponding lanthanide complexes, students will become familiar with common analytical techniques such as NMR, HPLC, MS, Luminescence, and UV-Vis Spectrophotometry.
