Joshua Spurgeon, PhD, is the Theme Leader for Solar Fuels research at the Conn Center and is focused on economically viable approaches to solar fuels, electrosynthetic fuel formation, and novel, low-cost solar cell technologies.

He received his doctorate in Chemical Engineering from the California Institute of Technology in 2010. He also holds an MS in Chemical Engineering from Caltech (2006) and a BS in Chemical Engineering from the University of South Carolina (2004). He conducted research on proton exchange membrane fuels cell at the University of South Carolina (2000 – 2004), before pursuing research into scalable and inexpensive nanostructured photovoltaics at Caltech (2004 – 2009). As a post-doctoral scholar at Caltech (2010), he worked on multifunctional membranes for solar fuels applications and demonstrated the viability of solar-driven water vapor electrolysis. He then became a Research Scientist at the inception of the Department of Energy’s solar fuels innovation hub, the Joint Center for Artificial Photosynthesis (JCAP, 2011 – 2013), where his research involved photoelectrochemical studies of the interfaces between catalysts and semiconductors. He became Project Lead for the Interface group and Processing, Materials, and Integration Team at JCAP (2013) before leaving for the Conn Center at the University of Louisville in 2014.

Josh’s research includes the study of novel photoelectrode materials for solar fuels generation, earth-abundant electrocatalysts for water-splitting, and the design and innovation of novel catalysts and electrolyzer systems for fuel formation through the reduction of carbon dioxide.

Sudesh Kumari, PhD, is currently a post-doctoral researcher at the Conn Center for Renewable Energy Research. She has previously worked on the development of organometal halide perovskite solar cells as well as hydrogen production through the electrolysis of ambient water vapor. Currently her research focuses on the investigation of plasma-synthesized electrocatalysts for water oxidation. She is also developing a plasma-assisted electrochemical synthesis of ammonia from nitrogen and water. Sudesh received her undergraduate degree from Panjab University Chd. in India before completing her PhD in Chemistry from the University of Kentucky in 2014. At UK, she studied electron and ion spectroscopy of metal hydrocarbon complexes.

Jacob Strain is a graduate student at the Conn Center for Renewable Energy research. He is studying the electrochemical reduction of carbon dioxide to liquid fuels such as ethanol. His work involves the design of heterogeneous cascade catalysis systems to increase the selectivity of desirable multicarbon products. This work involves the design of multistage electrolysis reactors as well as characterization of the reactions which lead to ethanol and other multicarbon species.
