Lisa McElwee-White is currently the Colonel Allen R. and Margaret G. Crow Professor of Chemistry at the University of Florida.

Career

Lisa McElwee-White received her B.S. degree in Chemistry from the University of Kansas in 1979, and completed her Ph.D. degree at the California Institute of Technology under the supervision of Dennis A. Dougherty. After two years of postdoctoral work at Stanford University with James P. Collman, she joined the Stanford faculty as an assistant professor in Chemistry in 1985.

She moved to the University of Florida as an associate professor in 1993 and was promoted to Professor in 1997. Following a term as Associate Dean for Administrative Affairs in the College of Liberal Arts and Sciences, she returned to full-time conducting research and teaching in 1998. She currently serves as director of the UF Beckman Scholars Program and recently served as the Director of the NSF-CCI Center for Nanostructured Electronic Materials. Professor McElwee-White's current research interests center around the applications of organometallic chemistry in materials science.

Her work has been funded by a variety of federal agencies, foundations, and private companies including NSF, DOE, ARO, ONR, NASA, ACS-PRF, the Beckman Foundation, HHMI and FEI. She has authored more than 140 peer-reviewed publications and has presented more than 180 invited lectures. Her Editorial Board service includes Organometallics, the Journal of Organic Chemistry, Letters in Organic Chemistry and Current Organic Chemistry. She has recently served as Chair of the Division of Organic Chemistry of the American Chemical Society and was named as a Fellow of the American Chemical Society in 2010. Her recent awards include the Florida Award (2015) and the Charles H. Stone Award (2012).

Research

Chemical Vapor Deposition

Chemical Vapor Deposition (CVD) is a technique that produces materials by depositing solid films. It has been a very attractive process because it is chemically selective process, the material produced is high-quality and high-performing, and the thickness of the film can be easily controlled.

McElwee-White has studied the various complexities of CVD on tungsten nitride and carbonitride films (WN_xC_y films), exploring tungsten nitrido complexes as precursors and analyzing the effect of ligand structure on the reaction. She has also expanded her research scope to the metallization of organic thin films. For the process of metallization of organic thin films, normal thermal CVD processes which require high temperatures usually destroy organic films. McElwee-White introduced photochemical CVD processes as an alternative, and employed ruthenium-based precursors.

Electron Beam-Induced Deposition

Electron beam-induced deposition (EBID) uses a high energy, focused electron beam to deposit nanomaterials onto a surface using organometallic precursors. It is useful because it is able to produce three-dimensional nanostructures with well-controlled size, shape and interparticle distance. McElwee-White has explored EBID using a variety of organometallic precursors, such as cis-Pt(CO)₂Cl₂ to make pure platinum nanostructures and (η3-C₃H₅)Ru(CO)₃Br to make Ru-based nanostructures and to study the effects of ligands.
