Jon R Kirchhoff

Dr. Jon R. Kirchhoff is the Chair of the Department of Chemistry & Biochemistry at the University of Toledo's College of Natural Sciences and Mathematics, holding the title of Distinguished University Professor. His research integrates electrochemistry, analytical chemistry, and materials science to develop advanced solutions for environmental challenges, neurochemical analysis, and metal extraction.

His work focuses on electrochemical sensor development using modified electrodes (gold nanoparticles, graphene composites), conductive polymers like poly(caffeic acid), and composite sorbents for water treatment. Recent publications highlight applications in critical rare earth element extraction, precious metal recovery, and toxin removal via biochar and nanocomposite materials.

His scientific awards include a 2023 patent for pyrrole-based polymers in metal extraction and the Distinguished University Professor title, reflecting his contributions to

• environmental chemistry,
• bioanalytical methods,
• and nanomaterials engineering.
