Michael Barnes

Michael Barnes is a Professor in the Department of Chemistry at the University of Massachusetts Amherst, where he also serves as the Graduate Program Director. He is affiliated with the Materials Science and Engineering Interdisciplinary Graduate Program, reflecting the interdisciplinary nature of his research. His work is conducted in the Physical Sciences Building and the Lederle Graduate Research Tower.

• Ph.D., Rice University (1991)
• B.S., California State University, Sonoma (1985)

His research focuses on the chemical physics of nanoscale systems, particularly the relationship between structure and optoelectronic function in polymeric and inorganic composite nanostructures. He employs a technique known as “Chemical Microscopy,” which integrates single-molecule imaging, spectroscopy, and scanning probe methods like atomic force microscopy (AFM). His work spans quantum dot-organic hybrids, polythiophene nanostructures, and chiral molecules, with implications for energy harvesting and advanced optical technologies.

The available publications, both from 2012, center on exciton dynamics and structural properties in conjugated polymer systems such as polythiophenes and P3HT nanofibers. These studies utilize advanced optical techniques to probe inter- and intrachain interactions, solvation effects, and regioregularity at the nanoscale, revealing insights into charge transport and photophysical behavior relevant to organic photovoltaics.

While no formal scientific awards are listed in the provided text, his research has been published in high-impact journals such as Science and the Journal of Physical Chemistry Letters. He advises a research group comprising graduate students and researchers, and collaborates with prominent faculty including Prof. Todd Emrick and Prof. Latha Venkataraman.

Dr. Barnes leads the Barnes Research Group, which investigates single-molecule photophysics, chiroptical responses, and nanostructure functionality. The lab focuses on systems such as CdSe-organic composites, polythiophene nanoparticles, and chiral fluorophores, aiming to bridge molecular structure with macroscopic optoelectronic behavior.
