Jennifer MarleyJennifer Marley is originally from Raleigh, North Carolina.  She earned a B.S. in Electrical Engineering with a concentration in Renewable Electric Energy Systems from North Carolina State University in 2012. At UM, she worked with Ian Hiskens.  Her research focused on modifying traditional optimal power flow formulations and solution methods to integrate both storage devices and renewable generation sources into power systems. 
Jonathon MartinJonathon Martin grew up in Lancaster, Pennsylvania and received his Bachelor’s Degree in Engineering from Messiah College in Mechanicsburg, PA.  While there, he had the opportunity to gain hands-on experience in the energy field working on electrification projects in developing regions around the world with the Collaboratory.  Before moving to Michigan in 2012 to pursue a Ph.D. in Electrical Engineering: Systems, he also spent a summer working with PPL, an electric utility in eastern Pennsylvania.

Jonathon’s interests involve the reliable integration of renewable energy and storage into existing electrical networks.  His past work has included the study of reactive power capabilities of wind-farms and the application of optimal corrective control decisions to large electric power system networks following system contingencies.
David ReedDavid Reed was in the Electrical Engineering: Systems program at the University of Michigan in Ann Arbor, and worked under the supervision of professors Jing Sun and Heath Hofmann. He received his Bachelor’s and Master’s degrees in Electrical Engineering from Pennsylvania State University (University Park) in 2007 and 2009, respectively. From 2009 to 2011, he was an associate staff member at MIT Lincoln Laboratory, where he worked on a variety of projects ranging from power supplies for satellite payloads, to controls for airborn optical sensor platforms. As an undergraduate and master’s student, he spent summers working part-time as a sound engineer for a small Pittsburgh-based audio production company, as well as two summers interning at Bechtel Bettis Atomic Power Laboratory working on power electronics for naval power systems.

His research focused on the development of adaptive control methodologies for simultaneous identification and control of over-actuated systems, with application to AC drive systems. Other research interests include applications of nonlinear and adaptive control to electromechanical systems, optimization-based control of energy storage systems, as well as control-theoretic approaches to understanding human locomotion and learning.
