个人简介

Christine Thomas was born in 1980 in Cinnaminson, NJ, a suburb of Philadelphia. She graduated from Cinnaminson High School in 1998 and went on to recieve her bachelor of science degree in chemistry from Lafayette College (Easton, PA) in 2001. As an undergraduate, she worked with Professor Chip Nataro on the synthesis and electrochemistry of inorganic complexes, including phosphine-crown ethers and mixed valent ruthenium dimers. In the fall of 2001, Christine began her doctoral studies in inorganic chemistry at the California Institute of Technology (Pasadena, CA). Christine's research with Professor Jonas C. Peters focused on a wide range of synthetic projects related to inorganic and organometallic chemistry, including the examination of C-H activation by platinum complexes, the design of new ligands, the examination of the reactivity of coordinatively unsaturated tris(phosphino)borate iron complexes towards small molecule activation, and the synthesis of the first well-defined and structurally characterized Fe(IV) imido complex. After recieving her Ph.D. in inorganic chemistry in 2006, Christine went on to pursue postdoctoral work under the direction of Professors Marcetta Y. Darensbourg and Michael B. Hall at Texas A&M University (College Station, TX). Her postdoctoral research concentrated on the experimental and theoretical investigation of small molecule models of the dinuclear active site of [FeFe]-Hydrogenase, an enzyme that catalyzes the reversible production of hydrogen from protons. In 2008, Christine accepted a position as an Assistant Professor of Chemistry at Brandeis Univeristy (Waltham, MA). Professor Thomas's research program focuses on synthetic inorganic and organometallic chemistry with the underlying goals of exploring fundamental design principles used by Mother Nature in catalyst design for renewable energy and sustainable technological applications. In 2010, Prof. Thomas was selected for the U.S. Department of Energy's Early Career Research Program and in 2011, Prof. Thomas was named a 2011 Alfred P. Sloan Fellow. Christine is also the recipient of a 2012 National Science Foundation CAREER award and was selected as a 2012 Organometallics Fellow and a 2013/2014 Chem. Commun. Emerging Investigator. Christine's dedication to teaching was recognized with The 2012 Michael L. Walzer '56 Award for Excellence in Teaching at Brandeis. In 2012, she joined the Editorial Advisory board for Chemical Communications. Prof. Thomas was promoted to Asssociate Professor with tenure in May 2013. As of May 2014, she is an Associate Editor for Dalton Transactions.

研究领域

Synthesis of new ligands and transition metal complexes with the ultimate goal of uncovering new approaches to the catalytic activation and functionalization of small molecules and organic substrates.

My research plans entail the synthesis of new ligands and transition metal complexes with the ultimate goal of uncovering new approaches to the catalytic activation and functionalization of small molecules and organic substrates. These types of processes are critical for the development of sustainable energy technology and for the catalysis of organic transformations. Although I am interested in a number of different projects, the underlying theme for my research program is to examine the ways in which different components of a transition metal complex work together and how this cooperation affects the reactivity of the complex as a whole. Specifically, I am interested in examining the cooperation between two metal centers in bimetallic frameworks metal centers and non-innocent ligands Although the primary focus of my research is synthesis, the research pursued my group also entails a large variety of characterization techniques including multinuclear NMR, IR, UV-Vis and EPR spectroscopies, as well as magnetic and electrochemical measurements. In addition, theoretical investigations into the electronic structure and reactivity of particularly interesting transition metal complexes synthesized in my research group are studied using density functional theory (DFT) calculations.
