Matthew McDowell joined Georgia Tech in the fall of 2015 as an assistant professor with a joint appointment in the George W. Woodruff School of Mechanical Engineering and the School of Materials Science and Engineering. Prior to this appointment, he was a postdoctoral scholar in the Division of Chemistry and Chemical Engineering at the California Institute of Technology. McDowell received his Ph.D. in 2013 from the Department of Materials Science and Engineering at Stanford University.

McDowell’s research group focuses on understanding how materials for energy and electronic devices change and transform during operation, and how these transformations impact properties. The group uses in situ experimental techniques to probe materials transformations under realistic conditions. The fundamental scientific advances made by the group guide the engineering of materials for breakthrough new devices. Current projects in the group are focused on i) electrode materials for alkali ion batteries, ii) materials for solid-state batteries, iii) interfaces in chalcogenide materials for electronics and catalysis, and iv) new methods for creating nanostructured metals.

The Strategic Energy Institute is excited to welcome Scott McWhorter as a 2023 Distinguished External Fellow. Scott will co-lead the concept development, visioning, partnership, and preliminary capture activities for Georgia Tech on the Department of Commerce Tech Hubs (“Hubs”) and expand Georgia Tech’s hydrogen activities and stature.

Scott is not new to the Georgia Tech campus and has previously worked with Dan Campbell of the Georgia Tech Research Institute (GTRI) on developing trace organic optical sensors based on evanescent waveguides. More recently, Scott worked with David Sholl (professor in the School of Chemical and Biomolecular Engineering at Georgia Tech through 2021), to develop the RAPID (Rapid Advancement in Process Intensification Deployment) Institute and then through his work with Southeast Hydrogen Energy Alliance (SHEA), started working with Comas Haynes of GTRI on hydrogen, where they brought together the ecosystem that was responsible for at least three hydrogen hub efforts in the South East.

Scott's work related to energy in his own words: 
My career has always related to energy even when I didn’t notice it. I started out in DNA microchips where we tried to understand the various aspects of fluidics (mass transport, thermal, and surface science) that influenced efficient separations. Using the tools from those efforts I transitioned into optical sensor development to monitor trace gases from the gas-solid catalyst interface in a fuel cell electrode to an unknown-unknown contaminant that might cause a failure mode in a weapons system. Over the past decade, my work in energy has focused namely on building partnerships in industrial manufacturing consortia (ManufacturingUSA Institutes) where I helped form both CESMII and RAPID and then focusing on developing technologies to solve the hydrogen storage and delivery challenges through either more efficient, energy dense solid-state storage or using electro magnetics to efficiently provide heat to catalysts to decompose a hydrogen carrier or plastic.

Bojan Petrovic joined Georgia Tech in 2007 as a Professor. Prior to that he acquired industrial experience as a Fellow Scientist in Westinghouse Science and Technology where his primary responsibility was as the project Deputy Director on the development of the advanced, modular IRIS reactor.

Dr. Petrovic's current research focuses on advanced reactor design, nuclear fuel cycle and waste management, and related modeling and simulation methods.

Over the past ten years, he has been involved in the development of the IRIS Reactor, within an international team of 19 organizations from ten countries. IRIS is an advanced medium power (335 MWe) integral-type PWR, based on proven light-water technology, but incorporating many innovative solutions that improve its operation, safety, security, and economics. Advanced reactors have the potential to offer full benefit in synergy with advanced fuel cycles. Recently, the focus of this research is shifting to judicious selection of fuel cycle, reprocessing, and partition and transmutation options, which  may significantly reduce the radiotoxicity of spent nuclear fuel and enable its safe and economical ultimate disposal.

Novel reactor designs and advanced fuel cycles pose new challenges and require improved, more accurate methods of modeling and simulations. Dr. Petrovic's interest is in developing approaches for using Monte Carlo and hybrid deterministic-Monte Carlo methods (for eigenvalue as well as shielding applications) in a way that will be practical and relevant for analysis of complex nuclear systems.

Dr. Petrovic has a strong interest in interdisciplinary areas, and his research projects have included collaboration related to industrial and medical applications of nuclear technology. His recent research in computational medical physics focuses on proton therapy. His research has been sponsored by the Department of Energy, industry and utilities.

Dr. Kotlyar profoundly believes in education through research and thus integrates practical reactor system design into his lectures.

Materials for membranes, sorbents, and barrier packaging applications rely upon the same fundamental principles. Thermodynamically controlled partitioning of a penetrant, such as carbon dioxide into a membrane, sorbent or barrier packaging layer is the first step in the transport process. If the material is a polymer, cooperative motions of the matrix enable diffusive motion by the penetrant. In highly rigid carbon molecular sieves and zeolites, motion of the matrix is negligible, and penetrant transport is governed by the relative size of pre-existing pores and the penetrant molecule.

Koros’s group is a leader in developing advanced materials for membranes, sorbents, and barrier applications by optimization materials to either promote or retard transport of specific components. For instance, for a chosen penetrant such as carbon dioxide, the Koros group can create a barrier, a selective membrane, or a sorbent by materials engineering. Work is also underway in the Koros group to form “mixed matrix composite” materials comprised of blends of metal organic framework or other specialty components within the matrix of a conventional polymer. This approach allows further optimization of transport properties without sacrificing the ease of processing associated with conventional polymers.

Effects due to non equilibrium thermodynamic and non-Fickian transport phenomena are additional topics his group studies. Long lived conditioning effects due to exposure of membranes and barriers to elevated concentrations of certain penetrants are typical of such non equilibrium phenomena. Protracted aging of glassy polymers, carbons, and inorganic membranes after formation or conditioning treatments also are of interest to his research group. In many cases, these effects seem to defy logic—until one realizes that an expanded set of rules governs these out-of-equilibrium materials.
