- My
research interests are in the area of theoretical
and experimental population biology. I am involved
in a collaborative research program that uses insect
populations to test predictions of nonlinear population
dynamics, including chaos. I am also working with
Dr. Robles and his students on computer models of
intertidal community dynamics. For more details

My
research focuses on molecular studies of natural populations
and the application of results to the conservation and
management of endangered marine mammals. I investigate
genetic differentiation on an evolutionary scale, among
populations, within social groups and between the sexes.
I currently study populations of spotted dolphins, Stenella
attenuata, that are affected by the tuna purse-seine
fishery in the Eastern Tropical Pacific Ocean.

My
research activities are designed to investigate the
effects of sunlight on pollutants at the air-water
interface. For example, sunlight may react with elevated
nitrate concentrations in watersheds to change the
oxidation capacity of the water and the air. In addition,
many pesticides in air and water are decomposed by
sunlight; however, little is known about the decomposition
products. My research group investigates these types
of fundamental questions using ion chromatography
and LC/MS/MS.

My
background is in plant ecophysiology, and my interests
lie in understanding patterns of photosynthetic function
and plant productivity in nature. Recently, I have
been applying optical methods (reflectance and fluorescence)
to explore photosynthetic processes, both in the lab
and in the field. My lab group also studies the impacts
of ozone on plant physiology, and is using remote
sensing to examine global change impacts and the interactions
between fire and vegetation. For more details on the

I
am an environmental engineer interested in the fate
of pollutants and nutrients in the natural environment.
Our goal is to understand how the physiochemical properties
of particles affect chemical fate and transport in
air and water. Processes studied include: sorption/desorption,
atmospheric transport and deposition and aquatic cycling
and transformations of chemicals. For more details

am interested in the ecology and evolution of marine
invertebrates, with particular emphasis on planktonic

species in the sea. For more details on my lab research,

- Using
controlled experiments in the rocky intertidal zone,
my students and I test hypotheses about the forces
shaping marine communities. Our most recent experiments
demonstrate that variation in the recruitment of prey
species influences the activities, and hence, the
regulatory role of keystone predators. Future studies
will consider the impact of global climatic change
on the dynamics of marine communities. For more details
on the work in my lab, please click here.

I
am interested in the interactions between microbes and
the environment. As a molecular microbial ecologist,
I use classical microbiology and molecular biology techniques
to study the diversity of bacteria in a variety of environments
such as soils, natural waters, plant surfaces, and the
hindgut of termites. By observing bacteria both in their
natural niches and in the test tubes of the laboratory,
I hope to better understand the chemistry carried out
by these microscopic organisms and their role in the
biogeochemical cycling of the elements.
