Dr. Roesler specializes in the engineering analysis and experimental testing of thermal and flow processes and equipment. He consults in the areas of fire and explosion investigation, computational fluid dynamics (CFD) analysis, and alternative energy safety and performance. 

Dr. Roesler's work at Exponent includes the evaluation of fire and explosion incidents, including origin and cause investigation, and equipment failures. He also has expertise in evaluating industrial facilities, such as natural gas distribution equipment, for compliance with federal, state, and local regulations. He has broad experience in laboratory and field testing, including the design, construction, and instrumentation of customized experimental apparatus for project-specific problems. Dr. Roesler also has CFD modeling experience with commercial software such as ANSYS Fluent and Star-CCM+, computer-aided design (CAD) experience with SolidWorks, and scientific computing experience in MATLAB and Python.

Prior to joining Exponent, Dr. Roesler completed his Ph.D. research at Dartmouth College, where he conducted model-scale experiments on a novel ship propeller design, and CFD modeling work for cross-flow propellers and hydrokinetic turbines. Dr. Roesler built a software design tool in MATLAB for cross-flow devices using a Vortex Lattice Method (VLM) model, and performed detailed studies using ANSYS Fluent commercial CFD software for model validation. He developed this tool in collaboration with the Ocean Renewable Power Company (ORPC) and researchers at the Penn State Applied Research Laboratory (ARL) to design a commercially viable cross-flow turbine. Dr. Roesler's research furthered the understanding of the unsteady forces acting on cross-flow devices due to hydrofoil vortex shedding and non-linear wake interaction.
