Dr. Arias is a mechanical engineer in Exponent's Thermal Science Practice, consulting primarily in the areas of thermo-fluid processes, aeroacoustics, and failure analysis. His areas of expertise encompass computational fluid dynamics, sensitivity analysis, aeroacoustics, and statistical analysis. Dr. Arias has worked in simulating industrial processes such as ventilation systems in confined spaces, stirred vessels, and gas dispersion, using commercial packages including Star-CCM+.

During his time at Exponent, Dr. Arias has utilized multi-dimensional modelling to assist in failure analysis for investigations related to fire, explosion, and gas dispersion, as well as the characterization of newly designed devices, including specialized catheters and fans for consumer electronics. Prior to joining Exponent, Dr. Arias graduated with his Ph.D. from the University of Maryland, where he developed a new methodology to aid in shape optimization and uncertainty quantification. This new method allows the use of high-fidelity models, like the large eddy simulation (LES), to predict the change in a quantity of interest when a design parameter changes. Dr. Arias graduated with his M.Sc. from the University of Campinas, Brazil, where he designed and analyzed numerical experiments to characterize aerodynamic noise around wings. Before graduate school, Dr. Arias worked as a Reliability and Project Engineer where he helped in determining the integrity and reliability of physical assets for clients in the oil & gas and power generation industries.

Dr. Arias is proficient at coding in Fortran, C++, Python, MATLAB, parallelized programming languages like MPI (Message Passing Interface) and Open-MP.
