Independent Scientific & Technical Consulting
for Advanced Materials, Devices, and IR Systems
Helping startups, research teams, and SBIR programs translate deep materials chemistry and physics into sound technical decisions, credible proposals, and executable development plans.
How I work with teams:
Most of my work sits at the boundary between theory, experiment, and program execution. I’m typically brought in when my expertise in materials and infrared sensors or my experience in government funding, research execution, or engineering management can assist teams with their programs.
Sean Keuleyan, Ph.D. is an independent scientific and technical consultant with 17 years of experience in materials science and engineering, semiconductor and infrared optoelectronics, optical modeling, device fabrication, and experimental characterization. He partners with industry, startups, and research teams to solve complex technical problems, develop credible R&D strategies, and translate materials science research into launchable results. His work emphasizes clear assumptions, quantified risks, and decision-ready deliverables, with particular strength in proposal development, data analysis, and advanced technical writing.
