Expert has an earned PhD in Civil and Environmental Engineering and is currently research professor at a major water research lab. His primary focus is Fluid Mechanics and Hydraulics with other interests in Hydrology. His expertise includes physical modeling of dams and spillways, open channel flows, testing of valves, pipelines, and flow meters. He has developed hydraulic structures for energy dissipation including baffled hoods for Howell-Bunger valves. He is a licensed professional engineer and is regarded as a hydraulic engineering subject matter expert.

Provided consulting for hydropower development on multiple hydroelectric power installations. Expert's services included water hammer analysis and cavitation analysis. He provided consulting services for an energy dissipating hood to be used in conjunction with a Howell-Bunger valve. In fact, he developed the design of the hood and it has been installed in multiple location. Expert provided hydraulic analysis of a canal bypass to be used for hydroelectric power development. The analysis included a computational fluid dynamics simulation. He provided hydraulic analysis of pipeline that was re-lined with mortar in which the mortar was placed too thick. The analysis showed that the losses were relatively minor. Expert also provided flood investigation for homeowners suffering from damage related to a cloudburst rainstorm.

Expert may consult nationally and internationally, and is also local to the following cities: Logan, Utah - Salt Lake City, Utah
