ARLINGTON, VA, September 05, 2025 /24-7PressRelease/ -- Peter N. Mikhalevsky, PhD, has been selected for inclusion in Marquis Who's Who. As in all Marquis Who's Who biographical volumes, individuals profiled are selected on the basis of current reference value. Factors such as position, noteworthy accomplishments, visibility, and prominence in a field are all taken into account during the selection process.

Dr. Mikhalevsky has dedicated over five decades to advancing the field of oceanic engineering, underwater acoustics and maritime systems, spanning the military, academia, and private industry, starting with his commissioning in the U.S. Navy in 1972, then as a professor on the faculty of the Massachusetts Institute of Technology (MIT) and finally joining Science Applications International Corporation (SAIC) now Leidos. He made important contributions to national security in sonar, and array signal processing and is an expert in acoustic remote sensing applications for sampling ocean temperature and currents. His recent work is focused on underwater navigation and improving our sampling of the ocean in time and space at the scales needed to support global climate models and improve their forecasting skill.

Dr. Mikhalevsky served on active duty in the U.S. Navy from 1972 to 1984, and in the U.S. Navy Reserve from 1984 to 1993 retiring with the rank of Commander focusing on Anti-Submarine Warfare (ASW). While on active duty he was instrumental in the introduction of tactical towed arrays for surface ships in the Navy in the mid-1970's. He was the ASW officer on the first destroyer in the fleet to get an experimental towed array in 1973, demonstrated breakthrough operations in the Mediterranean that led to the operational SQR-18 and 19 towed array systems. In 1976 as a lieutenant (junior grade), he received a Letter of Commendation from the Chief of Naval Operations "for exceptional professionalism," for his work on "an in-depth study regarding aircraft carrier defense in the Mediterranean… that contributed greatly to our body of knowledge in anti-submarine warfare." While in the Navy, Dr. Mikhalevsky was stationed on ice camps in the Arctic conducting research and gathering data for improving sonar performance. He received the Navy Achievement Medal in 1981 for "substantial contributions to anti-submarine warfare research by his efforts toward Arctic Programs which provided meaningful results and expanded knowledge in this critical surveillance area."

He joined SAIC in 1985, (now Leidos since 2013). Leidos is a Fortune 500 company focused on solving complex health and national security challenges. Shortly after joining the company, he started a new division and rose to senior vice president, building a successful $200 million per year business in advanced ocean undersea systems, providing high technology science, engineering, and systems development services from basic research to fielded systems supporting our national security. Highlights include the development of the 140 ton MDUSV (Medium Displacement Unmanned Surface Vessel), under contract with the Defense Advanced Research Agency, and christened Sea Hunter by the U.S. Navy, advanced undersea acoustic trainers, and supporting the design, construction, and installation of 5 of the 6 hydro-acoustic stations of the Comprehensive Test Ban Treaty Organization (CTBTO) global International Monitoring System (IMS). Dr. Mikhalevsky's 50 years' experience in Arctic acoustics, oceanography, and experimentation, included being on seven ice camps in the high Arctic, 2 as Chief Scientist. He was Chief Scientist and Principal Investigator of many ocean acoustics experiments worldwide. In 1994 he transmitted the first trans-Arctic, 2,600 kms, coherent acoustic spread-spectrum waveforms, validating sonar equation terms for Arctic Ocean acoustic propagation and detected basin scale warming in the Arctic Intermediate Water caused by warming Atlantic water entering the Arctic in the West Spitzbergen Current. He repeated that experiment in 1998-99 and measured continued warming. These results were subsequently confirmed by ice breaker and submarine transects. He created the triad design for the hydro-acoustic stations of the CTBTO/IMS, significantly improving each station's localization capability, false alarm rejection, and improved use of reflected phases enabling applications beyond ocean nuclear testing deterrence. He has a patent for GPS denied underwater navigation, 24 published papers in books and peer reviewed journals and 66 papers in conference proceedings.

Dr. Mikhalevsky's academic journey includes a Bachelor of Arts and Master of Science jointly awarded from Harvard University, followed by a doctorate from Massachusetts Institute of Technology. In 1984-85 he was Associate Professor at MIT in the Department of Ocean Engineering, teaching Marine Data Systems, a graduate course on the acquisition and analysis of acoustic, oceanographic, and seismic data, the fundamentals of spectral estimation, and conventional and adaptive array processing. His education laid a strong foundation for his technical expertise in the propagation of sound in the ocean and acoustic data processing. Looking back on his accomplishments, he is immensely grateful for the unwavering love and support of his wife, Litsa, who provided strong insightful advice throughout his career.

Professionally, Dr. Mikhalevsky acknowledges the support of Prof. Ira Dyer, his Ph. D. committee chair at MIT (deceased), and Prof. Emeritus Arthur Baggeroer at MIT, both of whom provided invaluable technical and career advice, mentorship and friendship. Dr. Mikhalevsky also thanks Leidos/SAIC for the tremendous opportunities, resources and trust invested in him to pursue his technical vision over his now 39 years with the company.

To commemorate his numerous contributions to maritime systems' advancement, Dr. Mikhalevsky has been honored with numerous accolades throughout his career. He received the Distinguished Technical Achievement Award from the Institute of Electrical and Electronics Engineers (IEEE) Oceanic Engineering Society in 2017, the Executive Science and Technology Council Publication Prize from SAIC in 1999 and Leidos in 2024, the Decibel Award 1981 from Naval Undersea Warfare Center, New London, CT, the A.B. Wood Medal and Prize 1983 from Institute of Acoustics, U.K., and the R. Bruce Lindsay Award 1984 from Acoustical Society of America. Dr. Mikhalevsky is a Leidos Technical Fellow, Fellow of the Acoustical Society of America (1993), and Fellow of the IEEE (2008).

Happily married, a proud father of two children and grandfather to four, Dr. Mikhalevsky cherishes spending quality time with his family, playing golf, traveling, and wine tasting in his spare time. Looking to the future, he aims to advance acoustic remote sensing technology for ocean measurements and data collection, enhancing infrastructure for deep-sea sampling to address gaps in climate models. His continued passion for collaboration with colleagues and sponsors drives his commitment to operationalizing these capabilities for global benefit, cementing his legacy of making a positive impact on others through all he does.
