Our research group is advancing the understanding and control of the light-matter interface. We are housed in the Department of Chemistry at the University of Illinois, Urbana-Champaign with affiliations in Physics and the Beckman Institute on campus. We perform a portion of our experimental work at the Materials Research Lab and are also are a part of the UC Berkeley-UIUC Energy and Biosciences Institute. Our theoretical work uses facilities of the National Center for Supercomputing Applications and XSEDE.

Light-matter interactions are central in nature, life, and in technology. There are three aspects of the light-matter interface that we study using spectroscopy, microscopy, and theory:

i) We employ the rich interplay between visible light and metal catalysts for selective formation of energy-dense chemical bonds.

ii) We image with unprecedented resolution chemical reactions on surfaces or in nanoparticles and uncover their mechanistic pathways.

iii) We design materials and coax them into exhibiting non-natural optical or optoelectronic phenomena

In summary, we are learning how to control and harness light as a source of energy and as a means to control the attributes and function of advanced materials.

We are always looking for graduate students from our Chemistry, MatSE or Physics graduate programs to join us. If you are already admitted to one of these programs, please contact Prof. Jain by emailing jain (at) illinois (dot) .edu for openings. For prospective students who have not yet been admitted to a UIUC graduate program, please contact the program of your interest for information about admissions. Students are admitted into a department or a program and not into a group

Currently there are no openings for postdoctoral scholars, but typically candidates with experience in electrochemistry, catalysis, surface science, and optical microscopy may write to Prof. Jain by emailing jain (at) illinois (dot) edu with a CV, one selected representative publication, and a 1-page-or less research statement. Please arrange to have three recommendation letters sent to Prof. Jain.

Our research is at the intersection of chemistry, materials science, and condensed matter physics, areas in which UIUC has programs ranked in the nation's top 5 and has been home to 20 Nobel laureates & discoveries/ inventions such as the LED, MRI, and theory of superconductors. UIUC also houses the world-class Materials Research Laboratory, where we perform a lot of our work.

Our group is diverse in several respects. We value inclusiveness and support and cherish the successes of all of our group members link. In our science, we value quality over quantity.
