Management

Sergey Ermilov, Ph.D.

CEO

Dr. Ermilov is an entrepreneur and a co-founder of PhotoSound. As a CEO of PhotoSound Technologies, he oversees the strategic business development and company operations. Dr. Ermilov has received Master of Biomedical Engineering degree in 1998 from Bauman Moscow State Technical University (Russia), followed by two years of formal business education through the President of Russia Program in Professional Management at BMSTU with a graduate work focused on commercialization of an innovative therapeutic system. For his scholastic achievements Dr. Ermilov was awarded a summer business internship at the Manchester Business School (UK), sponsored by the European Management Training Program (TASIS). In 2014 he was leading the team from Tomowave Laboratories, Inc. in the pilot NIH I-Corps business training program learning the aspects of efficient commercialization for biomedical startups.

Dr. Ermilov is also a scientist with 20 years of experience in biomedical optics and 14 years of experience in biomedical photo- (opto-) acoustics. In 2006 he was awarded a Ph.D. in Bioengineering from Rice University (USA) where he was using Nobel Prize winning technology of optical tweezers to study biomechanics of specialized inner-ear cells as a part of the global effort to understand the fundamentals of human hearing, hearing loss, and develop efficient therapeutic strategies. During his subsequent startup employment at Fairway Medical Technologies and TomoWave Laboratories, Dr. Ermilov got introduced to photoacoustics and eventually became a world-class research expert in the field. He participated and later was leading the successful development of several biomedical photoacoustic technologies including real-time imaging systems based on a hybrid combination of photoacoustics and ultrasound and a 3D photoacoustic tomography. Dr. Ermilov’s scientific expertise and interests in the field of biomedical photoacoustics include system development, imaging algorithms, computer modeling, and theory. He is a Principal Investigator of two active and one completed NIH SBIR Phase I projects. Dr. Ermilov is an author of 22 peer-reviewed publications and 5 U.S. patents related to the field of photoacoustic imaging. At PhotoSound Technologies he is also leading the R&D on preclinical in vivo imaging instrumentation.

Hans Peter Brecht, Ph.D.

COO

Dr. Brecht, earned his M.S. in applied laser technology in 2002 from the University of Applied Sciences Oldenburg-Ostfriesland-Wilhelmhaven, and his Ph.D. in biomedical sciences in the Department of Cellular Physiology and Molecular Physics at the University of Texas Medical Branch (UTMB) at Galveston in 2007. For his thesis, he specialized in the non-invasive optoacoustic detection of blood oxygenation in large blood vessels. He designed custom optoacoustic transducers and fabricated them. He developed new data acquisition and signal processing for the project. After receiving his Ph.D., he worked for Fairway Medical Technologies where he led the design of a small animal optoacoustic imaging system for research in drug delivery and blood distribution monitoring. He then started working at Physical Optics Corporation, in Torrance, Ca where was involved in the development of an acousto-optic imaging system, Raman‑based Lidar systems, and led the development of animated articulated flame test manikins for the testing of protective clothing, specialized tools for the Joint Strike Fighter program, as well as non-lethal weapons and crowd control devices. At Photosound he is responsible for the daily operations as well as the mechanical design aspect of the product development.

Vassili Ivanov, Ph.D.

​CTO, Systems Architect

Dr. Ivanov obtained his PhD in physics at the University of California, Los Angeles in the area of single molecule microscopy and statistical physics of biopolymers. His research at the National Institute of Diabetes and Digestive and Kidney Diseases spanned the area of in vitro reconstruction of minimal biological systems. At the University of Texas Health Science Center in Houston, Vassili developed a fluorescence lifetime correlation spectroscopy system used for measurement of receptor protein intrinsic motion on a sub-microsecond time scale. After transition from academia to industry Vassili specialized on parallel multichannel acquisition of small signals at the signal to noise level close to the thermodynamic limit of electric noise in the presence of strong EMI sources (for example, high power pulsed lasers used for opto- / photo-acoustics). At Tomowave he was developing data acquisition, power and motion control systems for preclinical and clinical research. He also worked on optimization of the products for certification and manufacturability. At PhotoSound Vassili is developing new analog and digital stages for data acquisition, motion control, power distribution and control systems.

Mark Little Ph.D

CCO, Chief Commercial Officer

Dr. Little is an application scientist and marketing director with 17+ years of experience in scientific instrumentation and tunable laser system design and sales. Dr. Little obtained a Ph.D. in Analytical Chemistry investigating fundamental processes and novel applications of tunable and fixed laser systems using mass spectrometry for the analyses of biomolecular samples. He used this experience to acquire NIH government funding to develop new optical parametric oscillator (OPO) devices for a variety of scientific fields including mass spectrometry imaging, hyperspectral imaging and photoacoustic imaging at OPOTEK, LLC in Carlsbad, CA. At OPOTEK, Dr. Little also promoted OPO products in the scientific community as the sales and marketing manager for the company. As the Chief Commercial Officer for Photosound Technologies, he will use his expertise to market novel photoacoustic imaging instrumentation using OPO laser sources. Dr. Little will help find new applications and increase the awareness and worldwide acquisition of Photosound products by research scientists with high technological backgrounds.
