Robert Elliott
A master instrument designer with over 45 years of experience bridging organic chemistry and advanced engineering. As the founder of J-KEM Scientific, he has deployed one-of-a-kind robotics and precision control systems for entities ranging from Oak Ridge National Laboratory to Abbott Labs (COVID-19 response). He specializes in custom automation, holding multiple patents in process control and sensor technology.
Jon Marsh
A physicist and "intuitive toolmaker" with over 30 years of cross-disciplinary experience, Dr. Marsh integrates deep learning, signal processing, and hardware design. Formerly a Senior Scientist at Washington University School of Medicine, his expertise spans from developing AI models for clinical pathology to designing hardware for airborne pathogen sampling and acoustic microscopy. He excels at solving complex problems at the intersection of engineering, medicine, and basic physics.
Gabriel Wade
A lead developer and designer at J-KEM Scientific, specializing in laboratory automation and mechanical engineering. His work is primarily centered on creating hardware that automates complex or manual laboratory tasks. In his capacity at J-KEM, his expertise is reflected in the categories of automated liquid handling in systems designed for high-throughput screening and synthesis, robotic integration of the physical components that allow software to control chemical reactions, and custom instrumentation development for "one-off" solutions for research labs that have unique physical constraints or material requirements.
Rajan Chakrabarty
A professor of Environmental and Chemical Engineering at the McKelvey School of Engineering, Dr. Chakrabarty leads the Aerosol Interdisciplinary Research (AIR) Laboratory, focusing on instrumentation development and engineering techniques for rapid detection of pathogens and biomarkers in complex environments including air.
Joshin Kumar
A leading innovator in environmental and chemical engineering, specializing in aerosol technology and biosensor development. He earned a B.Tech. in Chemical Engineering from the Indian Institute of Technology Bombay (2020) and a Ph.D. in Energy, Environmental, and Chemical Engineering from Washington University in St. Louis (2025). He pioneered the first single-target ECS-based biosensor for bioaerosol monitoring, and further advanced this field by designing BioAeroPlexN for multiplexed airborne pathogen detection. He is a named inventor on multiple patents related to rapid, label-free bioaerosol detection.
