Dr. Wozniak is an assistant professor in CEOE's School of Marine Science and Policy. As a marine organic geochemist, he is interested in research that addresses questions related to carbon cycling, climate, air and water quality, and marine ecology. Andrew specializes in the characterization of organic matter that exchanges between the land, ocean, and atmosphere using traditional and advanced analytical techniques (e.g., Fourier transform ion cyclotron resonance mass spectrometry, nuclear magnetic resonance spectroscopy, gas chromatography mass spectrometry, isotope ratio mass spectrometry). In particular, he uses these tools to: 1) characterize source-specific organic matter compositions and understand how they relate to the impact or fate of that organic matter in the environment; and 2) determine the provenance of organic matter in environmental mixtures (e.g., sediments, aerosols, water, biological tissues).

The Wozniak lab has ongoing projects examining the relationships between oceanographic conditions and surface seawater, sea surface microlayer, and sea spray aerosol organic matter molecular compositions, controls on the quantities and molecular composition of soluble pyrogenic organic matter released from biochars, the use of multiple chemical tracers to evaluate bluefin tuna movements, and the impacts of anthropogenic activities on the molecular composition of organic aerosols. Dr. Wozniak is always looking to add graduate students and post-doctoral researchers to his group. Interested applicants or collaborators are encouraged to contact him directly (awozniak@udel.edu).
