Wagner joins Stubbins’ lab as post-doc

OLYMPUS DIGITAL CAMERASasha Wagner is a new post-doc in Aron Stubbins’s lab.

Sasha recently earned her doctorate in environmental chemistry from Florida International University. Her research interests include the reactivity and transport of fire-derived carbon (“black carbon”) in freshwater systems.  Initially considered to be a stable and refractory component of the organic matter pool, black carbon is actually quite dynamic and can be readily mobilized to surface waters where it is highly susceptible to photodegradation.  Sasha also characterizes dissolved organic matter on the molecular level using ultrahigh resolution mass spectrometry.  This method reveals unique molecular “fingerprints” which allow for the assessment of environmental effects on dissolved organic matter composition.

Sasha likes to decompress outside of the lab by running or cooking or trying a new type of beer. “ I am also on a quest to find a decent bagel in Savannah,” she says. “Suggestions are welcome!”
