the only representative from George Luthers lab, and thus
primarily responsible for all of the voltammetric analyses, which
allow us to measure different important chemical species from the
waters surrounding the vents.
What kinds of questions will you try to answer, and why?
We collect our data to attempt to better understand how the chemistry
of the vent systems affects biological distributions and processes.
We are especially interested in utilizing in situ voltammetric
techniques to determine real-time redox transition zone chemical
speciation. Dr. Luthers lab group has already successfully
used such measurements to characterize vent chemistry on previous
Alvin cruises, and more recently to characterize the chemistry
of the Black Sea oxic-anoxic transition zone on board the R/V Knorr.
Undoubtedly, the research we perform on Extreme 2001 will continue
to provide valuable information regarding relationships between
the chemical environment and the biological ecology associated with
What is your educational background? What lured you into marine
I have been interested in the oceans for as long as I can remember,
and I came to the University of Delaware College of Marine Studies
(CMS) after completing a bachelors degree in biology with
a minor in marine science at Pennsylvania State University. Since
then, I have completed a masters degree at CMS with an emphasis
in marine biology-biochemistry, while researching estuarine ecology
with Dr. Kent Price. Having always been curious about interactions
between organisms and their chemical environments, deciding to work
toward a Ph.D. with Dr. Luther as an adviser was an easy choice.
Since beginning the Ph.D. program, I have had great experiences
and we have had much success with redox transition zone studies
in various environments including salt-marsh microbial mats, coastal
bay sediments and water columns, hydrothermal vents, and the suboxic
zone of the Black Sea.
