Postdoctoral Scholar Marine Science Institute, University of California, Santa Barbara, Santa Barbara, CA (Feb 2013–Dec 2015). Advisor: David Valentine. Study oil slicks from natural oil seeps in the Santa Barbara basin to learn about the differential effects of evaporation and dissolution on polycyclic aromatic hydrocarbons (PAHs) and unsaturated alkanes. Design and build sampling devices for collection of sediment, gas, oil and microbial samples from natural oil seeps. Perform scientific sample collection from natural gas and oil seeps using scuba (AAUS certified diver). Apply for permits to perform sampling within several national marine sanctuaries. Participated in 2011 three-week SEEPS cruise on the R/V Atlantis off the coast of southern California (see Field Experience).
Postdoctoral Scholar Marine Chemistry Department, WHOI, Woods Hole, MA (August 2012–January 2013). Advisor: Christopher Reddy. Studied natural oil seeps in the Santa Barbara basin. Examined effects of evaporation, dissolution and biodegradation on petroleum polycyclic aromatic hydrocarbons (PAHs) in the absence of photodegradation. Studied the Deepwater Horizon spill and examined changes in oil washed up on beaches before and after Hurricane Isaac, 2012. Ran and maintained laboratory GC-MS for PAH analysis. Led collection efforts of samples from beaches impacted by the Deepwater Horizon spill and trained students/scientists in sample collection techniques. Performed sample extractions (soxhlet, liquid-liquid).
Graduate Student Marine Chemistry Department, WHOI, Woods Hole, MA (March 2008–May 2012). Advisor: Christopher Reddy. Studied the impacts of weathering on oil released from the 2007 M/V Cosco Busan oil spill in San Francisco Bay, San Francisco, CA. Examined effects of environmental processes Lemkau, p.2 including evaporation, dissolution, biodegradation and photodegradation. Used computer simulations and comprehensive two-dimensional gas chromatography (GC×GC) of field samples to tease apart the distinct effects of evaporation and dissolution to gain a more accurate understanding of spill toxicity. Provided a first look at the effects of environmental weathering on the high molecular weight fraction of this heavy fuel oil in the three years following the spill using ultrahigh resolution Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS). Participated in the 2009 two week SEEPS cruise on the R/V Atlantis off the coast of southern California (see Field Experience).
