Oakes Faculty Fellows

The Oakes College faculty represents a wealth of expertise from the natural sciences to the humanities, and we are proud to have some of the top scholars in the world among our faculty. Our students major in nearly every discipline at UCSC—from economics and computer science, to theater arts and Latin American and Latino studies—and they are well supported by the depth and breadth of the Oakes College faculty and the extensive knowledge of our advising team.

TBA is Oakes's faculty chair!

The Chair of the Faculty is an Academic Senate member, other than the Provost, who is elected by the college Faculty to serve a two year term, and will serve as a member of the Executive Committee.

Roger Anderson is interested in both experimental and theoretical aspects of chemical reactions, energy transfer and gas phase chemical processes that produce solid or liquid phase products.
Some members of his research group study the reaction mechanisms of light-activated chemical vapor deposition processes with particular emphasis on deposition of low dielectric constant materials. This work includes the photolysis and pyrolysis of inorganic and organometallic molecules, the kinetics of thinfilm growth, and the properties of thinfilm materials. Rates for elementary reactions and energy transfer processes are also measured with a variety of laser based techniques. Point-of-use synthetics of CUD reactants is another active interest.

He is starting a new research program in focusing of neutral polar molecules. Focusing provides an effective separation method that has important applications in analytical chemistry, isotope separation, lithography, and spectroscopy. However many of these applications have not been used because existing electrostatic lenses have severe spherical and chromatic aberrations. But Anderson has discovered methods to correct these aberrations, and the corrected lenses will have wide application. Equipment is being built to test the corrections.

Other group members study the kinetics of homogeneous nucleation and cluster growth. Large clusters of metals and dielectrics are grown in the laboratory. An important goal of this work is the characterization of the structure of protein-sized molecules with two or three parameters that are derived from small angle X-ray scattering experiments. Clusters are also grown on computers to provide tests of the meaning of the structural parameters that can be obtained.

Anderson also conducts research on the use of discrete representations in molecular quantum mechanics. Discrete polynomials that are orthogonal with respect to summation are very useful, and have some important advantages over the use of polynomials that are orthogonal with respect to integration.
