My long-term research interests lie in the field of environmental analytical chemistry, specifically, aquatic chemistry. Water is a central theme that ties together many of my past and current publications. In graduate school, my research involved using electrochemistry to understand metal speciation in aquatic systems, and this interest continued during my postdoctoral studies, where I studied iron speciation in the ocean. My current research projects involve studying the chemistry of urban runoff and its impacts on stream sediment chemistry and drinking water quality. At Dickinson, my students and I collaborate with Dr. Tom Arnold in the Biology Department on the development of new analytical methods for studying plant secondary metabolites.

2021-2022 Academic Year

Fall 2021

CHEM 141 Accelerated General Chem w/Lab
A one-semester introductory course for students who are especially well-prepared for general chemistry, replacing CHEM 131, 132 as a prerequisite for more advanced courses in the major. Topics include atomic structure, chemical bonding, thermodynamics, kinetics, equilibrium, electrochemistry, acid/base chemistry, solubility, and transition metal chemistry. The laboratory experiments will relate directly to topics covered in lecture, and will include statistical analysis of data, molecular modeling, instrumental methods of analysis, and quantitative analytical and inorganic chemistry. Admittance into this course is based on a placement exam. Three hours of classroom and three hours of laboratory per week.

CHEM 490 Environ. Chem. & Tox.
This course will examine the occurrence and fate of naturally-occurring and anthropogenic chemicals in the environment, especially those with bioactive properties. Topics will include how chemicals enter the environment, how they react once they are in the environment, and impacts on human and non-human organisms. This course is suitable for students having completed organic chemistry II.
