Postdocs and Visitors


Dr. Thomas M. Brenner

tmbrenner at

Thomas received his B.A. in physics from Carleton College in Northfield MN in 2009. He completed his PhD in Applied Physics at the Colorado School of Mines in 2014, with a thesis exploring monolayer modification of metal oxide contacts in organic solar cells. Following his PhD, Thomas joined the groups of Gary Hodes and David Cahen at the Weizmann Institute of Science, Israel under an Alternative and Sustainable Energy Initiative (AERI) post-doctoral fellowship. At Weizmann, Thomas studied charge transport and formation chemistry in halide perovskite semiconductors. Thomas is now continuing his AERI fellowship at the LESC, which he joined in August 2016. He is focusing on interface effects in all-solid- state batteries. Interface effects, such as chemical reactions between the electrode and electrolyte, can for example limit ion transport through the interphase layer or reduce capacity in cases of an extended reaction and are therefore potentially critical to battery performance.

XuefengDr. Xuefeng Wang

email: xuw079 at

Xuefeng obtained his M.S. in 2013 and Ph.D. in 2015, both from the Institute of Physics, Chinese Academy of Sciences (IOP, CAS). His interests are focused on the high-energy storage beyond Li-ion batteries, such as Li-S batteries, Na-ion batteries, Li-air batteries and Li-metal. His research in the IOP, CAS involved in exploring new electrode materials, designing nano-architecture, clarifying atomic structure, investigating intercalation mechanism and improving electrochemical performance of the Li-S and Na-ion batteries. He is also interested in the two-dimensional materials for the rechargeable batteries, such as graphene, layered oxides, transition metal dichalcogenides, Mxenes and so on. Currently, he is focusing on the understanding of catalytic mechanism for Li-air batteries as well as the growth mechanism and protection of Li metal.

Cyrus RustomjiDr. Cyrus Rustomji

email: crustomji at

Cyrus received his B.S. in Physics from UC Los Angeles in 2007 and completed his Ph.D in Materials Science from UC San Diego in 2015. His PhD and post-doc research involves novel electrolytes for both Li-ion and electrochemical double-layer capacitor devices capable of low temperature and high voltage operation for increased energy density. He has also previously held R&D positions in the super capacitor device and thin film electronics industries.

Mahsa SinaDr. Mahsa Sina

email: sina.mahsa at

Mahsa obtained her undergraduate degree in Materials Science and Engineering from Iran University of Science and Technology. She completed her Ph.D. at Rutgers University with major in characterization of renewable energy materials. Her research at Rutgers involved investigating the structural, morphological, and compositional changes of iron fluorides and oxyfluoride materials in Li-ion batteries using TEM/STEM. Her research focused on the understanding of operation and degradation mechanisms that occur on the nanoscale in Li-ion battery materials upon cycling. She received several awards such as Presidential Scholar Award from Microscopy Society of America (MSA) in 2013 and John M. Cowley Award in 2012. Her current research interests include developing new type of battery materials and characterizing their charge/discharge dynamic changes on the atomic-scale using in-situ TEM.

email: ayoda at

Akira Yoda is a visiting scholar from Denka Co., Ltd. He received his Master degree from Kyushu University. His research at Denka involved tailoring of conductive agent (Acetylene Black) for various positive electrode material and synthesis and electrochemical performance of positive electrode material / carbon composite as well as optimized conductive agent for high-voltage system. His current interest is research for conductive agent for the negative electrode in sodium-ion batteries.
