Kevin L. Hartman, Ph.D. is a patent agent in the firm’s Chemical Patent Prosecution group, focusing on patent preparation and prosecution for domestic and international clients in a wide range of technical areas including materials, nanotechnology, bioengineering, and medical devices.

Prior to joining the firm, Dr. Hartman worked at Seoul National University in Korea as a researcher to investigate various biosensing applications of nanotechnology. In his doctoral work at the University of California, Berkeley, Dr. Hartman used synthetic lipid membranes to study the binding properties of a classical cell adhesion protein, E-cadherin, and a part of the project was carried out in the Mechanobiology Institute at the National University of Singapore. In the multidisciplinary environment of the institute, Dr. Hartman’s research efforts led to the discovery that active cell processes are required to nucleate E-cadherin junctions.

Throughout Dr. Hartman’s international graduate and post-graduate career, he has additionally assisted scientists from a range of cultures and backgrounds in forming strong, clear arguments backed by their original research data.
