Matthew Sandlin, PhD

Mechanical Engineer


Matthew Sandlin is a mechanical engineer working in the Concentrating Solar Technologies program. Prior to working at Sandia National Laboratories, Matthew performed experimental testing and numerical validation of falling particle receiver concepts at the Georgia Institute of Technology. During his post-doctoral appointment at Oak Ridge National Laboratory, he performed experimental and numerical work in the areas of boiling heat transfer, heat exchanger analysis, and advanced heat exchanger design using additive manufacturing techniques. Matthew also was employed by a commercial concentrating solar power company and was responsible for research and development (R&D) of all thermal system components across multiple heat transfer fluids, including solar receivers, heat exchangers, and thermal energy storage systems. Prior to graduate school, he worked at a coal fired power plant tracking plant thermal performance and performing boiler inspections.
