Joshua D. Rhodes, Ph.D. is a Research Fellow at the Energy Institute and the Webber Energy Group at the University of Texas at Austin. His current research is in the area of smart grid and the bulk electricity system, including spatial system-level applications and impacts of energy efficiency, resource planning, distributed generation, and storage. He is also interested in policy and the impacts that good policy can have on the efficiency of the micro and macro economy, especially policy that utilizes market forces to increase efficiencies. He consults on a broad range of energy topics as well as vetting for novel technologies -- often sitting on vetting committees for companies looking to enter Austin's technology incubators. He holds a double bachelors in Mathematics and Economics from Stephen F. Austin State University, a masters in Computational Mathematics from Texas A&M University, a masters in Architectural Engineering from The University of Texas at Austin and a Ph.D. in Civil Engineering from The University of Texas at Austin. He enjoys mountain biking, rock climbing, and living it up in ATX. 

My research interests lie primarily in technical and systems-level analysis of resource consumption, generation, and efficiency. Most recent projects include estimating power generation costs, grid modeling, and storage analysis in the bulk electricity grid.
