Miles Greiner received his Ph.D. in 1986 from MIT where he helped develop the concept of hydrodynamic resonance. He joined the faculty of the University of Nevada, Reno (UNR) that same year and is currently Professor and Interim Chair of Mechanical Engineering. Professor Greiner served as the Interim Director of the University's Renewable Energy Center July 2011 to March 2013, and the Interim Chair of Mechanical Engineering July 2012 to June 2013. He received the Lemelson Award for Innovation from the College of Engineering in 2008, and was promoted to Fellow of the American Society of Mechanical Engineers (ASME) in 2006.

Dr. Greiner has taught graduate and undergraduate thermal science courses, engineering mathematics, freshman design, and has developed innovative, low-cost methods of teaching instrumentation and experimentation. He received educational funding from the US Nuclear Regulatory Commission (NRC) for the enhanced development of ME 475/675 Introduction to Combustion. He is currently developing a unique Graduate Certificate in Nuclear Packaging with funding from the US Department of Energy (DOE). He is a principal educator, along with Professor Dev Chidambaram, of the University of Nevada, Reno Graduate Fellowship Program on Thermal and Material Science for Nuclear Power, funded by the NRC. Professor Greiner was recognized by the University of Nevada, Reno Alumni Association as the Outstanding College of Engineering Senior Mentor in 1989 and 2001.

Professor Greiner has written extensively about channel topographies and flow conditions that enhance single-phase heat transfer at low Reynolds numbers without increasing pumping power. His experiments and simulations have documented the development and decay of normally-dormant two-dimensional Tollmien-Schlichting waves, and the subsequent development of three-dimensional mixing. These works have led to a basic understanding of flows in which heat transfer augmentation is not coupled with increased pumping power. The National Science Foundation, the Gas Research Institute, the United Technologies Research Center, and the US DOE have funded this work.

Professor Greiner and his students are currently developing and experimentally benchmarking computational fluid dynamics models of the conduction, convection and radiation transport within the interior of used nuclear fuel packages. The models will be used to assure the fuel cladding temperatures within these packages do not exceed safe limits under the pressurized conditions used during fuel storage and transport, and the rarefied conditions used during fuel drying and transfer operations. This work is funded by the US Department of Energy.

Dr. Greiner has also performed large-scale experiments and computational studies of heat transfer to massive objects engulfed in pool fires. This work has focused on the interaction between fires, the surrounding wind conditions and engulfed objects. It has led to an understanding of the thermal radiation properties of fires as well as the accuracy of inverse-conduction techniques used to measure heat flux in fires. He has used this work as a basis to estimate the response of truck- and railcar-sized used nuclear fuel transport packages under severe accident conditions. The DOE, Sandia National Laboratories, the Nevada Nuclear Waste Project Office, and Innovative Technologies Solutions Corporation have funded this work. Argonne National Laboratories has also funded Dr. Greiner to develop models of polyurethane foam under fire accident conditions. Based on work he performed in this area he received an award for co-authoring the Outstanding Operations, Applications, and Components Technical Paper at the 2003 ASME Pressure Vessel and Piping Conference, and the G.E.O. Widera Literature Award for co-authoring the Outstanding Technical Paper in the 2004 ASME Journal of Pressure Vessel Technology.

In addition to these topics, Dr. Greiner has performed proprietary research in the areas of gas turbine engine film cooling for Pratt Whitney, and advanced hydrogen reformer design for Hydrogen Burner Technologies Corporation.

Professor Greiner has performed extensive government service by assessing the adequacy of Federal Relations that specify the performance of used nuclear fuel transport packages in severe accidental fires. This service has been funded by the US Nuclear Regulatory Commission and the Nevada Nuclear Waste Project Office.
