Pauling Fellows Recipients

2015 Pauling Fellows

Garrett Goh

Garrett Goh graduated from the University of Michigan with a Ph.D. in Chemistry, where his doctoral research was supported by the Howard Hughes Medical Institute (HHMI) fellowship. At Michigan, he worked with Dr. Charles L. Brooks III on developing next-generation explicit solvent constant pH molecular dynamics capability for the CHARMM molecular dynamics program. His work in modeling pH effects in molecular simulations led to the discovery of pH-regulated transient conformational states and how they control the properties of pH-sensitive fluorescent proteins and the mechanism of RNA catalysis.

At PNNL, Garrett is part of the Computational Biology group in the Earth & Biological Sciences Directorate, where he will be working with Dr. Bill Cannon and Dr. Nathan Baker to develop new simulation capability for modeling cellular metabolism. His long-term scientific goal is to integrate metabolic simulations with his doctoral work in molecular simulations, for developing computational tools that will enable rational engineering of microorganisms relevant to biofuels research.

Kaathe Todd-Brown

Kathe Todd-Brown received her Ph.D. in Earth System Science from University of California Irvine. Her dissertation examined the representation of soil carbon in Earth system models used to inform the IPCC report. Previously, she worked at Massachusetts General Hospital in bioinformatics and obtained her BS in Mathematics from Harvey Mudd College.

In the Earth and Biological Sciences Directorate, her research will focus on linking microbial mechanisms mediating soil decomposition to ecosystem fluxes linked to climate change. Under the mentorship of Drs Vanessa Bailey, Nancy Hess, and Timothy Schiebe, Kathe will investigate new data streams to improve soil carbon models, as well as link models across spatial scales and various levels of process representation.

2014 Pauling Fellows

Luis Estevez

Luis Estevez received his B.S. in Mechanical Engineering at the University of Maine at Orono in 2007, graduating magna cum laude. A summer internship working under Dr. Anthony Puckett at the Los Alamos Dynamics Summer Session (2006), inspired Luis to realize his full potential by pursuing a Ph.D. in Materials Science and Engineering at Cornell University. At Cornell, Luis worked under the mentorship of Dr. Emmanuel Giannelis on projects spanning polymer based nanocomposite actuators, macroporous PEM fuel cell electrodes and eventually high surface area porous carbon materials for energy storage devices such as Li-S battery and supercapacitor applications. Luis is a member of the Phi Kappa Phi, Pi Mu Epsilon and Pi Tau Sigma Honor Societies and is a member of the Society of Hispanic Professional Engineers. While at Cornell, he was awarded a Sloan Fellowship, a GK-12 fellowship and the 2011 Zellman Warhaft Commitment to Diversity Graduate Student Award.

At PNNL, Luis has joined the Energy Processes and Materials Division in the Energy and Environment Directorate and is working with Dr. Jiguang (Jason) Zhang. Luis intends to continue his focus on advancing energy storage research by synthesizing novel hierarchical porous materials to be used as electrodes in battery and supercapacitor devices; particularly with applications towards electric vehicles.

Jeff Katalenich

Jeff Katalenich recently earned a Ph.D. in nuclear engineering and radiological sciences from the University of Michigan while researching the production of cerium oxide, sol-gel microspheres as a dust-free nuclear fuel fabrication technique. His Ph.D. research was supported by a National Defense Science and Engineering Graduate Fellowship, a National Science Foundation Graduate Research Fellowship, the Center for Space Nuclear Research, and the University of Michigan's Department of Nuclear Engineering and Radiological Sciences. Earlier, Jeff received a B.S. in mechanical engineering from Michigan Technological University where he managed a student satellite project for two years.

Jeff is expanding on his sol-gel microsphere doctoral research under the direction of Andrew Prichard within the Nuclear Engineering & Analysis Group and Signatures Science & Technology Division in the National Security Directorate. His project, titled "Solving the Plutonium-238 Problem," aims to demonstrate the fabrication of dust-free plutonium microspheres suitable for producing heat and electricity sources for space exploration applications.

2013 Pauling Fellows

Hans Bernstein

Hans Bernstein received his Ph.D. and B.S. in chemical and biological engineering from Montana State University. His Ph.D. work was supported through the National Science Foundation's Integrative Graduate Educational and Research Traineeship (IGERT-fellowship) in geobiological systems. Hans' research focuses on both applied and fundamental chemical reaction kinetics and transport in biofilms and microbial communities.

In the National Security Directorate, Hans is working under the mentorship of Helen Kreuzer on a project titled; "Exploring and Engineering Phototrophic-Heterotrophic Partnerships," which aims to identify controllable, cooperative ecological phenomena employed by phototrophically driven microbial communities for conceptualizing and engineering multispecies biocatalytic platforms.

Ryan Comes received his Ph.D. in Engineering Physics from the University of Virginia in 2013. Prior to that, he received a B.S. in Physics and a B.S. in Electrical and Computer Engineering from Carnegie Mellon University in 2008. His doctoral research focused on the directed self-assembly of epitaxial complex oxide thin films and was supported by the National Defense Science and Engineering Graduate Fellowship.

At PNNL, his research will continue to focus on epitaxial oxide films grown via oxide molecular beam epitaxy under the mentorship of Dr. Scott Chambers in the Fundamental & Computational Sciences Directorate and the Environmental Molecular Sciences Laboratory.

Patrick El Khoury

Patrick El Khoury received a B.S. in chemistry from the American University of Beirut in 2006, a Ph.D. in Photochemical Sciences from Bowling Green State University in 2010, and postdoctoral training at the University of California, Irvine.

In the Fundamental & Computational Sciences Directorate, Patrick combines surface-and-tip enhanced Raman spectroscopy with static and dynamic quantum chemical simulations to understand the behavior of a single molecule in its local environment. Under the mentorship of Wayne Hess, he plans to use the fundamental understanding gained from such studies to construct plasmonic devices with various functionalities.
