Robert S. Cargill, PhD: Bob is the President and CEO of PDT. He holds undergraduate degrees in electrical engineering and biochemistry and a PhD in molecular biology and neuroscience. In his prior semiconductor industry experience at Maxim Integrated Products, he introduced a family of cable modem amplifiers as well as three families of ISM-band wireless transceivers, launching two successful product lines. He performed project management, product definition, circuit design and simulation, mask design, laboratory characterization, and production test.

Seeking opportunities to commercialize biotech intellectual property, he earned a certificate in Technology Entrepreneurship from a joint OHSU/University of Portland business training program. Working with Ken Ward, he co-founded PDT. Bob also serves as a senior electrical engineer and is principal investigator for two PDT federal grants.



W. Kenneth Ward, MD  Ken is a scientist who specializes in biosensors. He is Chief Science Officer, Board Chairman, and co-founder of PDT. He has been deeply involved in development of percutaneous glucose sensors (iSense, Bayer), a lactic acid sensor, and developed a subcutaneous oxygen sensor for the US Department of Defense for the purpose of detecting occult blood loss. Dr. Ward has had research grants from JDRF, NIH, CDC and DoD and, with his colleagues, developed a very effective bihormonal artificial pancreas algorithm. In his academic role, he was for many years a member of the JDRF artificial pancreas consortium, but has now left academia and is employed full time at a company he cofounded, Pacific Diabetes Technologies (PDT). In the spirit of simplifying the life of people with diabetes, PDT’s first goal is to develop a subcutaneous catheter that can be used not only as an insulin conduit but also to measure glucose continuously.

Dr. Ward has published 75 original articles, 7 book chapters, and 11 review articles, mostly on the topics of diabetes technology and biosensing. He has been awarded 22 patents and has 8 patents pending.



Gregory S. Herman, PhD   (Associate Professor, Oregon State University)   Dr. Herman was awarded a PhD in Chemistry from University of Hawaii in 1992. During his work at Hewlett-Packard and Sharp laboratories, he developed expertise in various automated printing techniques and in flexible circuits. One of his current specialties at OSU is the use of specialized printing methods for depositing a variety of compounds, including proteins. He is a member of the American Chemical Society and the American Vacuum Society (AVS). He is also an Elected Member of Executive Board for the Nanometer-Scale Science & Technology section of the AVS. Dr. Herman is currently the co-director of the Oregon Process Innovation Center for Sustainable Manufacturing.

Dr. Herman, his graduate students, and one post-doctoral fellow have worked closely with the team at Pacific Diabetes Technologies for over 18 months. They optimized a procedure for printing of glucose oxidase on to a small platinum electrode.



John F. Conley, PhD   (Professor, Oregon State University): Dr. Conley holds a PhD from Pennsylvania State University (1995) in Engineering Science and Mechanics. He has five years of industry experience (Sharp Labs) and six years of academic experience (OSU) in atomic layer deposition (ALD). He is experienced in designing and developing general semiconductor processes, in particular (a) ALD thin films and nanolaminates for Si CMOS devices, and (b) conformal coating and surface modification of nanostructured materials. He has more than 10 ALD related patents, more than 30 ALD related publications, and numerous ALD related presentations including many invited talks. His wealth of technical experience will be leveraged to accelerate the development of this proposed project and help ensure its success.

To date, Dr. Conley and his team have carried out the work of applying Pt and Ag electrodes for the PDT sensing catheter. By exploring various adhesion layers and other methods, they have optimized the method of applying adherent films to flat polymer substrates. Dr. Conley and his graduate students/post-docs have worked closely with Drs. Ward and Cargill at PDT for over 18 months.




Kristin Morris, MEng:  Kristin is an accomplished computer engineer with a Master’s Degree in Engineering from Portland State University (2012). Her responsibilities at PDT include development of electronic boards and telemetry systems for pre-clinical studies and for bench top biosensor testing. She is also deeply involved in the development of a body-worn electronics module that will be used in humans in the future — it will acquire, store and transmit biosensor data.
