    Speaker information:
    In 1995, Dr. Sukesh Roy received his B. Sc. degree in Mechanical Engineering from BUET and, in 2002, Ph.D. from Texas A&M University. He has an exemplary record of accomplishments as a leading scholar in aerodynamic measurement technologies, and a co-founder and CEO of Spectral Energies, LLC, a small business with a portfolio of over $15M per year focused on research, development, and commercialization of these technologies. He is a Fellow of the Optical Society of America (OSA), the American Society of Mechanical Engineers (ASME), and an Associate Editor of Optics Express.​

    Dr. Roy’s numerous and groundbreaking contributions to laser-based spectroscopy and imaging have focused on understanding the complex structure of turbulent flames, detonations, supersonic and hypersonic flows, and plasmas. His leadership has led to major advancements in three specific areas: (1) the introduction of ultrafast-laser based spectroscopy and imaging for temperature, velocity, and key chemical species concentrations in reacting and non-reacting flows; (2) the advancement of burst-mode laser-based spectroscopy, imaging, and complex data analytics for high-speed multi-dimensional flows; and (3) the development of robust instrumentation for ground testing, including fiber-coupled spectroscopy and imaging for harsh environments with limited optical access. He has led the research community for innovations in fs and ps coherent anti-Stokes Raman scattering (CARS), fs two-photon laser-induced fluorescence, and ps molecular tagging velocimetry. ​

    Dr. Roy’s leadership in burst-mode laser diagnostics and laser systems has transformed a very complex and limited capability into a broadly applicable approach by (i) increasing the burst energy by orders of magnitude for sustained MHz imaging in high-speed flows, (ii) expanding the pulse-width range from only nanoseconds to span nine orders of magnitude from femtoseconds to microseconds for a wide variety of spectroscopic approaches, (iii) expanding its use from planar imaging to 3D tomography, and (iv) developing a compact, portable, and turn-key system that could be used in academic and national laboratory ground test facilities. These developments have led to numerous “firsts” in measurement technologies.​
