Professor

Professional Summary

Dr. Albert M. Bobst is a Professor of Chemistry and Biological Chemistry at the University of Cincinnati. After receiving his PhD at the University of Zurich in 1965, where he synthesized, and characterized Tetrahydropterins by nuclear magnetic resonance, he studied for one year Quantum Biochemistry as a postdoctoral fellow with Professor Pullman at the Institut de Biologie Physico-Chimique in Paris, France. Subsequently he was awarded a Swiss National Science Fellowship to study Photosynthesis and Nucleic Acid Chemistry under the guidance of Professors Calvin and Tinoco, at Berkeley, CA. In 1968/69 he worked at Princeton University as a Research Associate before joining the Chemistry faculty as an Assistant Professor at the University of Cincinnati in 1969, where he was promoted to Professor of Chemistry in 1978. In 1975, he was appointed Adjunct Associate Professor of Biological Chemistry at UC’s College of Medicine, and promoted to Adjunct Professor in 1982. He was a visiting scientist at the National Institutes of Health in 1975/76, 1983/84, and at the ISREC in Lausanne, Switzerland, in 1979. In 2007/08 he was a visiting scholar at OSU.

His research interest is focused on the application of electron spin resonance (ESR) to: 1) Study the dynamics of nucleic acids and nucleic acid – protein complexes, and 2) Detect genes by PCR/ESR. In 2006 he was awarded US Patent 7,126,665 for “Detection of Nucleic Acid Target Sequences by ESR.” Presently, he has ongoing collaborations to design Micro – ESR sensors for magnetic resonance – based gene detection in personalized medicine.
