SUMMARY Ray has over 25+ years of experience at science & engineering, program development, project execution, and identification of business strategic opportunities in aerospace and commercial industries. After 18 years with United Technologies Research Center (UTRC), in 2017 he retired as an Associate Director of R&D in thermo-fluid science, with a focus on delivering innovation, customer requirements, advancing market differentiating technologies, and mentoring young talents leading to technical excellence. Prior to joining UTRC, he spent 8 years at NASA Langley Research Center (LaRC) as a senior scientist. In this role, he made significant advancements to laminar flow control supporting national High Speed Civil Transport (HSCT) program. Ray is regarded as an expert in boundary-layer stability and laminar-to-turbulent transition. In addition to fluid mechanics, he has extensive experience in areas including: laminar nacelle/fan/turbine design, axial compressors, aeromechanics, combustion dynamics, noise & vibration, rotorcraft, flight dynamics, two-phase flow, airfoil bearings, and advanced numerical methods.
