The North American shale gas boom has stimulated renewed interest in producing value-added products from light hydrocarbons. Unfortunately, the traditional industrial approaches to produce chemicals and liquid fuels from shale gas components are energy-intensive and have severe environmental consequences. The primary challenges include: (i) selective activation of light, saturated hydrocarbons such as methane and ethane is very difficult; (ii) the production of high-enthalpy products or intermediates, such as hydrogen, requires significant external energy inputs. The push for improved, less polluting, more efficient energy conversion technologies has spurred increased interest in catalyst development. In my career, I hope to further the use of catalyst characterization techniques to applied catalysis to expand both fundamental knowledge, as well as tools for the rational design of energy-conversion catalysts. I have significant research experience in the fields of: redox catalyst for chemical looping; selective oxidation of light hydrocarbons; heterogeneous catalysis (Synthesis, Reaction testing, Characterization); platinum group catalyst formulation; surface/catalyst characterization techniques; ultra-high vacuum (UHV) system operation and maintenance; research scale reactor design, optimization, and operation.
I have a strong interest in teaching fundamental chemical engineering subjects in addition to graduate and undergraduate courses closely related to my field (e.g. kinetics, catalysis/surface science). I also greatly enjoy training, mentoring, and collaborating with all levels of researchers down to undergraduates. In my postdoctoral work I have:
- Mentored Ph.D. students that, to date, has led to one peer review publication, two articles under review, and two nearing submission;
- Overseen interactions with facilities and environmental health and safety, and trained graduate students in best practices for laboratory safety and hazardous waste handling;
- Assisted collaboration between graduate students in the Chemical Engineering and Mechanical and Aerospace Engineering Departments;
- Successfully collaborated with graduate researchers in the Chemistry Department, leading to two high quality publications;
- Directly trained and supervised multiple undergraduates in the lab and supervised experimental plans for three masterâ??s students.
Research and Funding Successes: I have 14 authored and co-authored refereed articles across a variety of catalytic reactions. I have supervised multiple research projects, mentoring over 12 graduate and undergraduate researchers, and have participated in writing proposals, SOPOâ??s, and reports leading to project successes. I co-invented a novel chemical looping ODH technology, which was awarded $3.8 million overall ARPA-E funding and licensed to a commercial partner (EcoCatalytic LLC).
