Biography

Rodolphe Chabreyrie, Ph.D. is a technical advisor in the firm’s Electrical Patent Prosecution practice group where he is involved in drafting patent applications, providing technical support for patent prosecution in front of the USPTO, including analyzing Office Actions, prior art and drafting responses to Office Actions.

Dr. Chabreyrie advises and works closely with US patent attorneys on patent applications and freedom-to-operate opinions relating to the fields of automotive, aerospace, energy, medical devices, consumer products, oil and gas industry, packaging, semiconductor processing equipment.

In addition to providing technical support, Dr. Chabreyrie also uses his bilingualism (i.e. fluency in French and English) and biculturalism (French and American) to aid with communications as well as to garner and strengthen relationships with French speaking clients.

Prior to joining the firm, Dr. Chabreyrie held positions as a postdoctoral researcher at the George Washington University, the University of California San Diego as well as Carnegie Mellon University.

Through his journey from theoretical to applied nonlinear sciences, Dr. Chabreyrie actively committed his efforts to transferring powerful abstract ideas and mathematical tools to diverse concrete real world problems in engineering, oceanography and biology such as microfluidic mixers, mechanical and electrical oscillators, ocean transport, dynamics of fetuses, and breathing mechanisms of small insects.

Through these diverse research activities Dr. Chabreyrie established numerous collaborations and strong interactions with researchers from diverse technical backgrounds, e.g. applied mathematics, engineering, oceanography, biology and industry, and cultural backgrounds from top leading American and European universities and laboratories, e.g. Carnegie Mellon University, University of California San Diego, Woods Hole Oceanic Institute (WHOI), Centre National de la Recherche Scientifique (CNRS), Commissariat à l'Energie Atomique (CEA), and Saint-Gobain S.A.

Dr. Chabreyrie has written several grant proposals, scientific journal articles and done technical presentations at several international conferences as well as universities and R&D laboratories. He has also been a peer reviewer and performed numerous reviews for leading scientific journals. In addition, he has mentored/advised several graduate and undergraduate students through hands-on teaching activities dealing with applications of nonlinearity and chaos in engineering.
