Additionally, the war in Ukraine introduced further financial and social complexities. Despite these obstacles, Dr. Roy guided the department through these crises with resilience and innovation, ultimately strengthening its position within the university and beyond.

Dr. Roy's expertise encompasses acoustical oceanography, the physical and biological effects of ultrasound, high-intensity focused ultrasound for medical therapy, sonochemistry, and the interaction of sound and light for imaging and therapy. He is widely recognized for his pioneering research on bubbles and cavitation in ultrasonic fields, with significant contributions to biomedical and industrial acoustics.

Following his retirement from Oxford, Dr. Roy relocated to Maine, where he volunteers part-time at the University of Maine. He collaborates closely with the dean of engineering, providing feedback on program development and promoting engineering initiatives throughout southern Maine. From 2025 to 2026, he also served part-time as director of research and strategic partnerships at the Maine College of Engineering and Computing.

Dr. Roy's international influence is reflected in his concurrent appointments as visiting fellow at Durham Institute of Research, Development and Invention since 2025; honorary professor of biomedical engineering at The Hong Kong Polytechnic University since 2016; professorial fellow at Harris Manchester College at Oxford from 2013 to 2025; principal investigator at Oxford Suzhou Centre for Advanced Research from 2018 to 2022; interim theme lead for imaging with sound and light at Rosalind Franklin Institute from 2017 to 2019; associate head of department (research) at Oxford from 2016 to 2019; concurrent professor of acoustics at Nanjing University from 2017 to 2025; adjunct professor at Boston University from 2013 to 2016; and the 62nd George Eastman distinguished visiting professor at Balliol College, University of Oxford from 2006 to 2007. Dr. Roy is the first engineer to be named Eastman Professor in its 96-year history.

A notable highlight in Dr. Roy's consultancy work was his involvement with First Light Fusion in Yarnton, England—an Oxford spinout focused on shock wave-induced cavity collapse for nuclear fusion. Serving as a consulting engineer, non-executive director, and, later, external advisory board member between 2012 and 2025, he played a pivotal role in helping the company raise nearly £100 million in funding. He contributed technical expertise during its formative years.

Prior to his time at Oxford, Dr. Roy spent 17 years at Boston University, beginning in 1996 as an associate professor before advancing to full professor of mechanical engineering. He chaired the department from 2007 to 2013, where he shepherded the merger of the Mechanical Engineering and Manufacturing Engineering departments and led research efforts in high-intensity ultrasonics and acousto-optics for medical and industrial applications and bubble acoustics for Navy projects.

From 1991 to 1996, Dr. Roy held several positions at the University of Washington in Seattle: senior physicist and physicist IV at the Applied Physics Laboratory—a Navy-affiliated university lab—where he researched underwater acoustics, biomedical ultrasound and sonoluminescence; research associate professor in bioengineering; and affiliate associate professor in mechanical engineering.

Earlier roles included research assistant professor of engineering at the University of Mississippi from 1988 to 1991; research scientist at the National Center for Physical Acoustics during that same period; research associate and instructor at Yale University from 1987 to 1988; and director of research and development at Apfel Enterprises in 1987.

Dr. Roy's academic foundation is equally impressive. He received a Ph.D. in engineering and applied science from Yale University in New Haven, Connecticut, in 1987 after completing a Master of Philosophy there in 1985. He received a Master of Science in physics from the University of Mississippi in Oxford, Mississippi, in 1984, following a Bachelor of Science in engineering physics from the University of Maine at Orono in 1981. Finally, in 2006 he was awarded the Oxford MA ad eundem as part of his appointment as Eastman Professor.

His early fascination with laboratory work began during undergraduate studies when an opportunity led him to summer research under mentor Larry Crum at the University of Mississippi—a pivotal experience that introduced him to physical acoustics through hands-on experimentation with bubbles. This formative mentorship inspired his master's thesis on bubble dynamics and set him on a lifelong path exploring complex acoustic phenomena.

Throughout his career, Dr. Roy has been recognized for both technical innovation and leadership excellence. He holds fifteen patents related to acoustic technology and has authored more than 165 peer-reviewed articles spanning physical acoustics, biomedical ultrasound therapy, and related fields.
