The Bohn Research Group
Welcome to the Bohn Group homepage!
The Bohn Research Group is composed primarily of chemists and chemical engineers; we have also previously hosted visitors from the fields of materials science, physics, electrical engineering, mechanical engineering, and even psychology. Our research interests lie in using the tools of molecular nanotechnology to define the state-of-the-art in chemical analysis of mass-limited samples. Relying on a strong background in nanofabrication, high sensitivity molecular spectroscopy, and electrochemistry, we focus on problems in the areas of (1) low-dimensional analytical electronics and photonics, and (2) sensors and imaging.
​
Demographically, we are a diverse microcosm of the world, with researchers and group alumni from the US, India, Korea, China, and Germany.
We have strong connections to both the Department of Chemical & Biomolecular Engineering (College of Engineering) and the Department of Chemistry & Biochemistry (College of Science) at Notre Dame. Our group thus brings together researchers across disciplinary boundaries, departments, and colleges. In addition, we are closely associated with Notre Dame's Berthiaume Institute for Precision Health, one of the inaugural strategic research initiatives started by the University in 2008. With its sights set on treating diseases with personalized medication in the future, the BIPH actively seeks out ways in which various diseases can be identified at the molecular level. With this information, one's personalized treatment will have the best chance at success, lower trial-and-error rates, fewer side effects, and more precision. The group is also closely connected with the Center for Bioanalytic Metrology, partially led by Dr. Bohn. This center brings together researchers from Purdue University, Indiana University, the University of Notre Dame, and those from about 15 life science and biotechnology partners and approximately 6 analytical instrumentation partners, creating an ecosystem for innovation.

Congratulations to Julius Reitemeier on passing his ARP on October 12; onward and upward! Well done, Julius.
-
After a busy summer and start to the new academic year, Dr. Bohn travels this month to the University of Texas, Austin, to present a fall seminar, and he will close out the month with the Midwest Universities Analytical Chemistry Conference 2022 in Cincinnati. Several papers are forthcoming from our group; stay tuned!
June 2022
-
June witnessed the departure of our esteemed assistant research professor, Vignesh Sundaresan, as he moved to the University of Mississippi to assume an assistant professorship. Even though he is gone, Dr. Sundaresan continues to collaborate with several of our researchers on projects, and we enjoy our continued partnership.
