Jim Coe received his B.A. with Honors in 1980 from Swarthmore College, and his Ph.D. in 1986 from The Johns Hopkins University (advisor Kit H. Bowen) where he was awarded the Roseman Award for excellence in research. Postdoctoral work was done at the University of California, Berkeley (advisor Richard J. Saykally). He has been a faculty member at The Ohio State University since 1989, being promoted to Associate Professor in 1995 and Full Professor in 2007. He was given the Outstanding Service Award in 1999 by the ACS Columbus Section for work as Program Chair of the 31st ACS Central Regional Meeting, was elected a Fellow of the American Physical Society in 2008, and has been on the Editorial Board of the journal Plasmonics since 2005.

Research Overview

The Coe Group has been developing applications of Plasmonics in Chemistry, Physics, and Biology.  Our biggest application involves placing inhalable dust particles into the holes of a plasmonic metal mesh in order to record scatter-free infrared absorption spectra of subwavelength size particles.  This has led to a program in Environmental Chemistry to identify the chemical components of the dust that is breathed into people's lungs.  We are creating a library of single particle dust spectra, as well as calibranting materials that are known to be in dust, in order to better understand respirable dust.  In applying plasmonics to detection of cancerous liver tissues, e now have a program detecting Cancer.  We have joined a team of oncological surgeons, pathologists, and spectroscopists at the Ohio State Universy in order to develop spectroscopic probes for detecting cancer in surgically rsected tissues.
