Bradley Brennan

Bradley J. Brennan

2015 Resnick Postdoctoral Scholar

Brad obtained his undergraduate degree in chemistry and biochemistry-cell-molecular biology at Drake University. There he became interested in renewable energy and sustainability. This led to internships at the National Renewable Energy Laboratory and Texas A&M University on projects relating to solar energy and biorenewable materials. He later obtained his doctorate in chemistry at Arizona State University, focusing on mimicking plant photosynthesis to harness solar energy. The energy research theme continued at Yale University's newly-minted Energy Sciences Institute where he interfaced light-absorbing dyes and catalysts to couple solar energy to chemical reactions (solar-to-fuels). At Caltech, his research focused on preparation of new catalysts for solar-to-fuels devices. Brad explored linking multi-metal systems capable of substantial charge density to solar-derived electricity for the production of energy-rich chemical products. These could be used for energy storage or as starting materials for production of fossil-fuel replacements.

Sonja Francis

Sonja Francis

2015 Resnick Postdoctoral Scholar

Sonja was born in the twin island republic of Trinidad and Tobago. She graduated from the University of the West Indies, St. Augustine with first class honours in a BSc chemistry and management. For her graduate studies, she moved to Canada where she earned a PhD in chemistry at the University of Alberta in 2013 under the supervision of Steven Bergens. Her research focused on the development of alkaline alcohol fuel-cell catalysts. Sonja joined Caltech in 2014 and worked in the Lewis research group developing catalysts and product analysis methods for light driven and dark electrochemical carbon dioxide reduction. This reaction is important as it is a potential source of carbon neutral fuels and/or commodity chemicals.

Michael Haibach

Michael Haibach

2015 Resnick Postdoctoral Scholar

Michael did his undergraduate study at the University of Chicago and got his PhD in chemistry from Rutgers University in 2014. At Rutgers, he worked on breaking carbon-hydrogen and carbon-oxygen bonds using transition metal catalysts under Prof. Alan S. Goldman. This included the discovery of a greener method for the synthesis of alcohols from an unreactive type of molecule found in biomass. At Caltech, Michael worked on improving the catalytic dehydrogenation process. Catalytic dehydrogenation is a green chemical reaction that can transform an otherwise useless chemical using only non-toxic and abundant materials such as natural gas. His research explores ways to use this method to make chemicals that are relevant to human health.

Jing-Shun Huang

Jing-Shun Huang

2014 Resnick Postdoctoral Scholar

Jing-Shun worked in organic photovoltaics employing plasmon-enhanced long-distance energy transfer. Prior to arriving at Caltech, he spent two years at Yale University as a postdoctoral associate investigating Förster resonance energy transfer to improve the quantum yields of incident photons in polymer solar cells —and achieved a 38% increase in power conversion efficiency. Prior to arriving at Yale, he received his PhD in photonics and optoelectronics from National Taiwan University, where his work involved the invention of transition metal oxide inks for optical spacers in polymer solar cells, the development of organic-inorganic hybrid solar cells, and the design of ZnO nanostructures.

Deep Jariwala

Deep Jariwala

2015 Resnick Postdoctoral Scholar

Deep was born and brought up in India and completed his bachelor's degree in metallurgical engineering at the Indian Institute of Technology in 2010. As an undergraduate, Deep was a visiting summer student at Rice University for two consecutive summers where he worked on CVD synthesis of nanomaterials. He then joined Northwestern University as a graduate research assistant where he completed his PhD in materials science and engineering in 2015. At Northwestern, the focus of his research was investigation of opto-electronic properties and electronic circuit applications of heterostructure devices from two-dimensional (2D) materials. At Caltech, he developed nanophotonic architectures to enhance light absorption in 2D semiconductors and explored the efficiency limits in ultrathin photovoltaic cells from 2D materials.

Deep is currently an Assistant Professor of Electrical Engineering at the University of Pennsylvania.

Justin Jasper

Justin Jasper

2015 Resnick Postdoctoral Scholar

Justin researched sustainable water treatment technologies that conserve water resources while protecting the natural environment. He earned his PhD developing a novel open-water wetland cell that enhances the removal of nutrients and pharmaceuticals from wastewater effluent at UC Berkeley. This treatment technology has since moved from pilot-scale to the demonstration scale at the Prado Wetlands in Orange County. At Caltech, Justin worked on developing an off-the-grid electrochemical wastewater treatment system that generates bleach to disinfect wastewater, allowing water to be recycled for toilet flushing. System prototypes are currently deployed in regions where the infrastructure for conventional wastewater treatment is lacking, including locations in India, China, and South Africa. In 2015, Justin won the Dow-SISCA Runner-up Prize along with Cody Finke for the project, "Electrochemical+UV On-Site Wastewater Treatment".

Moureen Kemei

Moureen Kemei

2014 Prize Postdoctoral Scholar

Moureen completed her PhD at UC Santa Barbara (UCSB), where she studied the structure-property relationships in functional materials in the group of Professor Ram Seshadri. Her research has demonstrated that exchange interactions often couple strongly to the structure of magnetic materials, giving rise to long-range structural distortions. She has resolved the ground state structure of several spinel oxides—and these results are now guiding the prediction and interpretation of the properties of these magnetic materials. At Caltech, Moureen systematically investigated the electrochemical processes that occur in solid oxide fuel cell (SOFC) cathode materials. Her aim was to develop an accurate thermodynamic model of defect chemistry in SOFC cathode materials that would provide a framework for understanding transport mechanisms and cathode performance. The ultimate goal of her research was to establish universal guidelines for designing efficient SOFC cathode materials.

Allegra L. Liberman-Martin

Allegra L. Liberman-Martin

2016 Resnick Postdoctoral Scholar

Allegra obtained her undergraduate degree in chemistry from Scripps College. She completed her PhD in chemistry at UC Berkeley with Profs. T. Don Tilley and Robert G. Bergman. At UC Berkeley, she developed a strategy to reversibly control the reactivity of platinum complexes by addition of zinc, silicon, or boron Lewis acids. These studies suggested ways to improve catalyst design for hydrocarbon functionalization reactions. At Caltech, Allegra worked with Prof. Robert H. Grubbs to increase the efficiency of Grubbs olefin metathesis catalysts with nitrogen-containing substrates. These approaches require fewer reagents and result in fewer byproducts than conventional industrial processes, which may help create sustainable methods for the construction of polymers.
