Facilities

My lab is well equipped for the isolation of organic compounds from seawater, and their subsequent purification and chemical characterization. Small instruments include an HPLC with various detectors, a gas chromatograph with several detectors and inlets, a TOC/TON analyzer, several ultrafiltration and solid phase extraction systems. We are also well equipped to perform DNA purification and simple molecular biological analyses. In addition, we have one lab that is dedicated to preparing samples for natural abundance radiocarbon measurements, which, thanks to Roman and Roberta, has a state-of-the-art vacuum line for sealing and quantifying gas samples. As part of the various research projects we also culture both bacteria (on purpose) and phytoplankton, so we have dedicated areas of the lab for this purpose, including artificially-lit incubators.


In addition, my students use a variety of different instrument throughout SIO and UCSD, including state-of-the-art microscopes, NMR spectrometers, Elemental analyzers, an Isotope Ratio Mass Spectrometer, a MALDI-TOF Mass Spectrometer, Flow Cytometers, a LC-ES (with Ion Trap) mass spectrometer, and a single particle TOF mass spectrometer. In general, the community at SIO and UCSD is very generous with their equipment and time to graduate students and together with unlimited access to seawater ­ this makes SIO a great place for graduate students. In addition, I also collaborate with several outside investigators and facilities including LLNL-CAMS, Ellen Druffel and the Keck AMS Facility at UCI, Chris Reddy at WHOI, Ann Pearson at Harvard and Silvio Pantoja at UDEC, Chile.
