Dr. Rezvantalab specializes in complex fluids, heat transfer, mechanical testing, material characterization, and mesoscale modeling. He has an interdisciplinary background in mechanics, materials, and surface chemistry, and has applied his expertise to projects involving hydraulic fracturing, latex coatings, and composite foams. Dr. Rezvantalab has extensive experience in designing tests for measurement of mechanical/transport properties including compression modulus, electrical conductivity, and thermal resistance; manufacturing methods such as photolithography and metal forming; as well as imaging techniques including optical and scanning electron microscopy. He has analyzed the dynamics of polymers in lubricants and water-borne coatings, developed light-weight functional nanocomposites, and optimized the performance of industrial turbines and combined power and refrigeration cycles.

Dr. Rezvantalab has broad hands-on experience, from machine shop environment using lathes, welding and milling machines, to cleanroom environment working with microfabrication equipment, optical testing machines, and spin coaters. He is familiar with laser interferometry and compositional and microstructural analysis techniques such as Raman Spectroscopy. Complementing his hands-on skills, he has extensive experience with technical computing languages, and is proficient with a number of data analysis, image processing, and computer-aided design (CAD) software packages including Matlab, ImageJ, and SolidWorks. 

Prior to joining Exponent, Dr. Rezvantalab was a post-doctoral research fellow at the University of Michigan, where he conducted research on polymer migration under steep stress gradients and multi-scale modeling of colloids with rheology modifiers. He received his Ph.D. from Rutgers University in 2015, where his work involved a combination of experimental and computational projects concerning microfluidics, foams and emulsions, surface coatings, and interface stabilizers. Dr. Rezvantalab’s thesis dealt with computer simulation of the hydrodynamics and transport of amphiphilic particles at liquid interfaces. He also developed a low-cost aqueous-based process for fabrication of electrically-conductive foams suitable for EMI shielding and electrostatic discharge protection. His earlier work involved experimental investigation of heat transfer enhancement from an array of pipes using flow diverters.

While at Rutgers University, Dr. Rezvantalab served as the instructor for several courses including Fluid Mechanics, Thermodynamics, and Heat Transfer. He also contributed to the graduate student mentorship program and supervised multiple students on design/manufacturing projects.
