Experts in Subject: Chemistry

Biology, Chemistry, Community Based Learning, DNA, Gene Therapy, HIV-AIDS

Karl Haushalter

Karl Haushalter, PhD, researches DNA repair processes. Double strand breaks or chemically modified bases in DNA arise from exposure to ionizing radiation, environmental toxins, or mistakes during DNA replication. DNA repair enzymes scan the genome and fix DNA damage to maintain genomic integrity.  Studying the details of DNA repair provides an entry point into understanding the […]

Air Pollution, Atmospheric Chemistry, Chemistry, Climate Change, Photochemical Smog, Pollution

Lelia Hawkins

Lelia N. Hawkins, PhD, conducts research in the field of atmospheric chemistry. She studies how atmospheric particles in urban settings (like smog) are transformed as they age, specifically in fog and cloud water. These particles impact the temperature of the earth. Her work is largely concerned with organic compounds in atmospheric particles which (in Los […]

Asymmetric Catalysis, Chemistry, Education, Organometallics, Pedagogy

Adam Johnson, professor of chemistry, Harvey Mudd College

Adam Johnson conducts research in the field of asymmetric catalysis and organometallic coordination chemistry. His research group studies the conversion of straight chain organic molecules (aminoallenes) into nitrogen containing rings (pyrrolidines). These products and their synthesis are of potential interest for medical applications, as many pharmaceuticals have these nitrogen containing rings. The undergraduate students in […]

Chemical Sensors, Chemistry, Faculty Development, Mentoring of Women Science Faculty, Nanostructures

Kerry Karuktis

Kerry Karukstis, PhD, Ray and Mary Ingwersen Professor of Chemistry, researches classes of molecules that have the ability to self-assemble into complex three-dimensional structures when placed in water and other solvents. These 3-D configurations form using transient intermolecular forces (temporary interactions between molecules) and not permanent chemical bonds. Karukstis is interested in those chemical building […]

Chemistry, Environment, Metals in Biology

Katherine Van Heuvelen

Have you ever read the label on a bottle of vitamins and wondered why people need cobalt, zinc, iron and manganese? In nature these metals perform a remarkable array of chemical transformations that include water oxidation in photosynthesis, oxygen transportation by iron in red blood cells, and nitrogen fixation by bacterial nitrogenase enzymes. These reactions […]

Chemistry, Low-cost Photovoltaics, Pollution, Solar Energy

Hal Van Ryswyk

Hal Van Ryswyk, PhD, John Stauffer Professor of Chemistry, researches thin film photovoltaics, devices that convert sunlight to electricity. Examples include dye-sensitized solar cells utilizing nanostructured zinc oxide and bulk heterojunction cells constructed by printing or spraying inks made of lead sulfide quantum dots. The goal is to create low-cost photovoltaics that can be produced easily […]

Biosynthesis, Chemistry, Green Chemistry, Natural Products, Organic Synthesis, Religion

David Vosburg

David A. Vosburg, PhD conducts research on the preparation of medicinal compounds and the use of environmentally friendly methods in organic chemistry. He uses a variety of synthetic methods to construct complex molecular architectures. He has published extensively in organic synthesis, natural product biosynthesis, and chemical education. Before becoming a faculty member at HMC, Vosburg […]
