Course Information

At Pacific University, all faculty teach a variety of different courses. Typically, we do not use graduate teaching assistants, which means that your classes will be taught by professors and that you will have plenty of opportunities to get to know the faculty in your discipline.

Below I have listed some of the courses that I teach. We are always developing and trying out new classes, so the list may change now and then.

CHEM 300L  Fundamentals of Organic Chemistry Lab

CHEM 450 | ST: Chemistry of Mind-Altering Drugs

CHEM 486 | Capston Research

CHEM 495 | Research


Postdoctoral Researcher in Chemistry and Material Sciences, Lawrence Livermore National Laboratory, Calif., from 2005-2007

Ph.D. in Organic Chemistry, University of California at Santa Cruz, Santa Cruz, Calif., in 2005

Bachelor of Arts in History and Special Honors Curriculum with a Minor in English Literature, Hunter College, Park Avenue, N.Y. in 1990

Areas of Research & Specialization

Fluorescent chemosensors and biosensors, organic methodology, catalysts and methods for asymmetric synthesis, materials science, science education, philosophy and history of science, art & science and the science of art materials

Our research collective is currently conducting research in two areas: organic chemistry methodology and fluorescent chemosensors.  A few intrepid students are beginning to explore new photographic printing methods, but these studies are only beginning.

Project I: Organic Chemistry Methodology

This project involves developing new and selective methods for reduction of various functional groups. Our initial research focused on palladium-catalyzed reduction of alkenes and alkynes using sodium borohydride and was later modified to provide a method for the selective 1,4-conjugate reduction of unsaturated carbonyl compounds. This initial work developed into a systematic project and resulted in a publication in Tetrahedron Letters naming four students as co-authors.  Organic Methodology Research Poster (student poster)

Project II: Fluorescent Chemosensors 

This project involves the synthesis of fluorescent nanoparticles called quantum dots. The research is directed towards modification of these quantum dots to prepare chemical sensors for various analytes such as iron, vitamin C, and sugar. In such sensor systems, the degree of fluorescence, or brightness, of the analyte-sensitive quantum dots can be correlated with the concentration of the particular analyte. Quantum Dot Sensor Research Poster (student poster)

I have been fortunate to receive institutional support from Pacific University and additional funds from the Murdock Foundation for the support of this research.

Project III:  An Organic Chemistry Art Show, “100 Years of Organic Chemistry”

This is a series of oil paintings (pdf) featuring key personalities in the development of the science of organic chemistry.
