Education and career
Mulholland has a B.S. from the University of Notre Dame (1984), and an M.S. in biological oceanography (1986) and an M.M. in marine affairs (1992) from the University of Washington.[1] In 1998 she earned her Ph.D. in biological oceanography from the University of Maryland.[2] As of 2022 she is a professor at Old Dominion University.[1]
Research
Mulholland's early research examined the oxidation of amino acids[3] and nitrogen cycling by the marine bacterium Trichodesmium.[4][5] Her subsequent work investigated nitrogen cycling in harmful algae including Aureococcus[6][7] and Karenia brevis.[8] She has examined how phytoplankton will respond to an ocean enriched in carbon dioxide,[9] the impact of climate change on the Chesapeake Bay,[10] and the contribution of nitrogen-fixing organisms to nutrient cycling.[11][12] Her research tracks organic compounds in seawater, for example cyanate[13] or compounds produced by phytoplankton.[14] In coastal environments she has researched the impact of coastal flooding and the movement of pollution during floods.[15][16] As of 2022 she has an h-index of 46 and has publications that have been cited more than 7000 times.[17]
