Dennis Matthews's is an expert in developing optically based biosensors and medical devices. Dr. Matthews is Principal Investigator and Director of the UC Davis National Science Foundation?s Center for Biophotonics Science and Technology. He is also the Associate Director and Biomedical Technology Program Leader for the UC Davis Cancer Center that received NCI designation in 2002. In addition, Dr. Matthews is responsible for the development of industrial and medical applications of Lawrence Livermore National Lab (LLNL) technology, especially for the prevention, screening, diagnosis and treatment of diseases such as diabetes, stroke, brain trauma, chronic pain and cardiovascular disease.
Dr. Matthews leads a multi-directorate center within Livermore whose mission is to develop medical devices in collaboration with industry. Current projects and those already successfully transferred to industry include: an opto-acoustic recanalization device for treating ischemic stroke; a miniature x-ray source which is mounted on a microcatheter and used to treat coronary artery restenosis; micropower impulse radar for numerous medical diagnostics, including: differentiating hemorrhagic vs. ischemic stroke; an implantable, continuous-glucose monitor; and ultra-short-pulse laser microsurgery devices.
Dr. Matthews is widely acknowledged to have invented and developed the x-ray wavelength lasers. Among many other applications of that technology, he continues to collaborate with biologists in order to use x-ray lasers to generate x-ray images of living subcellular material, and with materials scientists to develop new methods of studying materials properties and defects. Finally, Dr. Matthews is extremely active in commercializing technologies developed at the national laboratories. He specializes in helping investors or small companies obtain the technologies needed to capture profitable new markets. He has already helped investors put together several start-up companies based on Livermore and other national lab technologies. He has broad scientific management and marketing skills, having managed programs as large as $30M/year while at Livermore and having successfully garnered project funding from both government and private sources.
