His research program explores the use of nanostructured material architectures for solar energy conversion. From 1996 to 2006, he was a research staff member at the IBM Thomas J. Watson Research Center in Yorktown Heights, New York investigating using polymer self-assembly for fabrication of high-performance semiconductor electronics. During his career, he has also performed experimental research in low-temperature scanning tunneling microscopy, single-electron tunneling devices, superconductivity in metal nanoparticles, nanocrystal-based electronic devices, and ferroelectric non-volatile memories. He earned his doctorate in physics from Harvard University and bachelor’s in physics and mathematics from Vanderbilt University. He is a fellow of the American Physical Society, a member of the Board of Directors of the Materials Research Society, and a senior member of the Institute of Electrical and Electronics Engineers.
He has been a Scientist at Los Alamos National Laboratory since 1999, starting as a post-doctoral researcher in 1994. Rod is the Los Alamos Program Manager for the Fuel Cell and Vehicle Technologies Programs. He has worked on fuel cells for transportation at both Los Alamos and General Motors. He has 13 U.S. patents, authored over 100 papers related to fuel cell technology with over 8300 citations and an H-factor of 34. He has led projects on hydrogen production, water transport and PEM fuel cell durability. He was the Principal Investigator for the 2004 Fuel Cell Seminar Best Poster Award, was awarded the 2005 DOE Hydrogen Program R&D Award for his team's work in fuel cell durability, received the U.S. Drive 2012 Tech Team Award for the Fuel Cell Technical Team, was recently selected as the 2014 winner of the Research Award of the Energy Technology Division of the Electrochemical Society and PI for the 2015 Fuel Cell Seminar Best Poster Award. He received a 2016 DOE Fuel Cell Technologies Office Annual Merit Award for Fuel Cells. He is a member of the DOE/US Drive Fuel Cell Technical Team, and is co-chair of the DOE Fuel Cell Technologies Office Durability Working Group and Director for the multi-lab consortium for Fuel Cell Performance and Durability (FC-PAD). As PI/co-PI, he has directed over $50M of funding at Los Alamos.
He is responsible for the development of science-based simulations for use in accelerating energy technology development. He was architect of the widely used, open-source multiphase CFD code, known as Multiphase Flow with Interphase eXchanges (MFIX), and led the development of software for linking process- and device-scale simulations and the C3M chemical kinetics software. As a fellow of the American Academy of Chemical Engineers, he specializes in multiphase flow, computational fluid dynamics (CFD), fluidization, and various energy processes. He is a founding technical director of National Energy Technology Laboratory’s Carbon Capture Simulation Initiative (CCSI). He has received numerous awards, such as the Energy Secretary’s Achievement Honor Award and American Institute of Chemical Engineers (AIChE) Fluidization Process Recognition Award. His many publications address topics, such as gasifier advanced simulation models; multiphase hydrodynamics of gas-solids flow; modeling coal gasification processes; hydrodynamics of particle segregation in fluidized beds; and simulation of granular layer inversion in liquid fluidized beds. He has a bachelor’s in chemical engineering from the Indian Institute of Technology (BHU) Varanasi, and a master’s and doctorate from the Illinois Institute of Technology in Chicago.
He is the technology manager of National Energy Technology Laboratory’s (NETL) Natural Gas and Oil Research and Development (R&D) program. In this capacity, he manages an R&D portfolio encompassing advanced technology projects ranging from basic energy science (modeling, materials development, sensors, controls) through large-scale field demonstrations and includes natural gas (shale gas), enhanced oil recovery, deepwater oil and gas production, and methane hydrates. He has 17 years of diversified engineering and management experience that spans a broad spectrum of technology areas including electric power generation, advanced greenhouse gas control, process control, coal conversion processes (oxycombustion, gasification and chemical looping), thermoelectric water management, and simulation/systems analysis.
Previously at NETL, he served as director of the Office of Coal and Power R&D Program and technology manager of the Carbon Capture Program and Engineering Systems Analyst. Prior to joining NETL, he worked as a chemical engineer for Science Applications International Corporation (SAIC) and as a research/process engineer for Calgon Carbon Corporation. He has a bachelor’s and master’s in chemical engineering from the University of Pittsburgh.
His research explores novel approaches for rational fabrication of designed nanoscale architectures through self-assembly. He developed methods for creating crystalline and cluster structures based on a programmable assembly of DNA-encoded, nano-objects. His interests include structural aspects of soft matter at nanoscale and at the interfaces, material transformation under environmental factors, and use of novel designed nanomaterials for optical, biomedical, and energy harvesting applications. He received a doctorate in physics from Bar-Ilal University (Israel) and performed his postdoctoral work at Harvard University.
His research spans battery research, protonic conductors, and fuel cells. He supervises the daily operation of the Battery Manufacturing Facility (BMF) at Oak Ridge National Laboratory (ORNL). His recent work at ORNL focuses on material processing and characterization, roll-to-roll manufacturing, electrode engineering, and cell manufacturing for low-cost, high energy and power density lithium-ion batteries with long calendar life. He developed novel techniques for electrode manufacturing, such as aqueous processing and electron beam curing, to reduce processing cost and environmental effect. He also developed several techniques for quality control to reduce scrape rate in cell manufacturing. He holds a doctorate degree from University of Florida and bachelor’s and master’s degrees from University of Science and Technology of China. All are in materials science and engineering.
