POSTDOC	Jeffrey M. Canfield
	B.S., Engineering Physics, 1990; M.S., Physics, 1991; Ph.D., Physics, 1997; University of Illinois at Urbana-Champaign. Postdoctoral Research, Ohio State University, 1997-2000; Postdoctoral Research, Emory University, 2000-. Jeff is engaged in experimental and computational investigations of the mechanism of radical-mediated catalysis in B12 enzymes. He has most recently developed the orientation-selection analysis for determining the 3D structure of reactant centers in ethanolamine deaminase reaction intermediates. Visit his personal web page.

GRADUATE STUDENTS
	Amos P. Kennedy
	B.S., Physics (Indiana University, 2000); M.S., Physics (Emory University, 2005). Amos' EPR studies of cryotrapped radical pair states in the ethanolamine deaminase enzyme has led to the successful completion of a M.S. degree. He is seeking a laboratory research position.

	Li Sun
	B.S., Physics (University of Science & Technology, Hefei, PRC, 2003) Li's experimental work involves application of electron-nuclear double resonance (ENDOR) spectroscopy to the determination of active site structure and dynamics in the ethanolamine deaminase enzyme. For the computational component of his Physics PhD/Computational Science MS degree, he is developing novel structural proteomics approaches to predicting protein structure.

	Miao Wang
	B.S., Applied Physics (Tsinghua University, Beijing, PRC, 2001); M.A., Physics (Univ. of Massachussetts, Amherst, 2002). Miao is using novel conditions to manipulate the reactions in the ethanolamine deaminase enzyme, in order to characterize the structure and dynamics of catalytic intermediates by using EPR spectroscopic techniques.

	Chen Zhu
	B.S., Biophysics (Nankai University, Tianjin, PRC, 2003). Chen is using a combination of kinetics studies and EPR spectroscopy to study the catalytic mechanism of the ethanolamine deaminase enzyme.

GRADUATE
ROTATION STUDENTS	Jessica Hernandez-Guzman
	B.A., Physics, Mathematics minor (Hollins University, 2004). Jessica's Summer 2005 rotation project involves characterizing the structures of complexes of copper(II) and the beta-amyloid protein, by using EPR and electron spin echo envelope modulation spectroscopy (ESEEM).

	Wesley Robertson
	B.S., Physics (University of Tennessee, 2001); M.S. Physics (University of Tennessee, 2003). For his Summer 2005 rotation project, Wesley is building a transient absorption spectrometer, with operating software. The instrument will be used to characterize the alkyl-cobalamin photolysis reactions in model and enzyme systems.

RESEARCH ASSISTANT	Mia Terashima
	B.S., Biology (Haverford College, 5/06). Mia is working in the lab this summer (2005), purifying the ethanolamine deaminase enzyme from bacterial cells. At the end of the summer, she will return for her senior year at Haverford College.
