The City Labs Team is comprised of a diverse group of scientists and engineers. The team has more than 30 years of experience interacting with various branches of the military and adheres to strict and discrete information control and exchange.

Peter Cabauy, PhD
Chief Executive Officer

Dr. Cabauy co-founded City Labs, Inc. in 2005, applying his diverse experience in technology, entrepreneurship, and experimental/theoretical physics to the structuring of the company and development of its product line.

In 2003, he founded and directed the Office of Entrepreneurial Science at Florida International University, advising in intellectual property matters, and laying the groundwork for its technology incubator program.

He received his Ph.D. from the University of Michigan in Applied Physics, with thesis work in Quantum Information Physics at Argonne National Laboratories (ANL). He co-authored a Physical Review A journal publication "Cyclic Networks of Quantum Gates" with thesis advisor, Dr. Paul Benioff, a seminal pioneer in the field of Quantum Computing. While completing his doctorate, Dr. Cabauy was also involved in microelectronics research at a Department of Defense (DOD) Laboratory. Dr. Cabauy also received his MS in Physics from University of Michigan and a BS in Physics from Florida International University.
Denset Serralta, MSEE
Chief Technology Officer

Denset Serralta co-founded City Labs, Inc. in 2005, after 27 years of professional experience in the embedded hardware/software design field. Since 1984, he has worked as a consultant for various defense, biotech and aerospace firms. His work includes compliance with military and other government standards and he holds Six-Sigma certifications at client sites.

Mr. Serralta's areas of concentration lie within the development of military, aerospace, and biotech systems. His specific skills sets include the utilization of Digital Signal Processing (DSP) and Object Oriented Design in various computer languages, several Real Time Operating Systems (e.g. vxWorks, Solaris, VDK), and various hardware platforms. Mr. Serralta has also assisted companies with analysis for the selection and integration of Commercial-Off-the-Shelf (COTS) components for development and production phases, as well as for sensor applications including radar, sonar, and communications & control DSP, network hardware/software, avionics, and biotechnology.

Larry Olsen, PhD
Director of Research

Dr. Olsen was instrumental in the development of City Labs' high efficiency, Tritium betavoltaic battery. He now leads the next generation development of City Labs' betavoltaic product lines.

Dr. Olsen is a pioneer in the area of betavoltaic technology and led the team that developed the first betavoltaic batteries (BetaCel) for cardiac pacemakers at Donald Douglas Laboratories (McDonnell Douglas Corp.). The Tri-Cities of Washington State named Dr. Olsen as the Tri-Citian of the year (1970) for this ground-breaking work.

Dr. Olsen was previously a scientist at the Department of Energy's Pacific Northwest National Laboratory (PNNL), where he developed programs in photovoltaics, thermoelectric energy conversion, and radiation detectors.

Prior to that, he was a professor in the Materials Science department of Washington State University, where he carried out research and development in Si-based solar cells, GaAs, and CuInSe2 (CIS). He received his Ph.D. in Solid State Physics from the University of Kansas and has published nearly 100 articles in his area of expertise. Recently, Dr Olsen was awarded R&D Magazine's R&D 100 award in 2009 for his collaborative work leading to the development in the Thermoelectric Ambient Energy Harvester.

Bret Elkind PhD
Senior Scientist

Dr. Elkind serves as the Senior Scientist and Radiation Safety Officer for City Labs, Inc., providing support over a broad range of areas including research and development, materials science/characterization, laboratory facilities and processing, regulatory guidance, radiation safety, and quality control. Prior to joining City Labs, Dr. Elkind served as Chief Scientist and Radiation Safety Officer for The Protective Group—an armor manufacturer for the U.S. Army.

Dr. Elkind's diverse technical background includes Nondestructive Evaluation [UT, XRD, optical, radiography], Environmental Scanning Electron Microscopy, mechanical testing, microstructural analysis, failure analysis, and ballistic testing. His career history spans commercial, government, academic, and start-up endeavors including armor design and manufacturing, Anti-Submarine Warfare systems analysis, structural engineering, construction materials testing, oceanographic sciences, and medical devices.

Dr. Elkind earned his BES, MSE, and Ph.D. degrees in Materials Science and Metallurgical Engineering from The Johns Hopkins University in Baltimore, Maryland, where he was also a Post-Doctoral Research Associate and member of the Alpha Sigma Mu Materials Science Honors Society.
