DL RobertsonDeborah Robertson, PhD
Associate Professor |
Research Interests: 
My research program investigates the physiological ecology and the evolution of nitrogen metabolism in marine diatoms and other ecologically important groups of marine algae. In many marine environments, nitrogen availability is an important factor regulating primary productivity. By characterizing the enzymes and regulatory pathways involved in nitrogen metabolism, this work should contribute to our understanding of the coupling between nitrogen metabolism and productivity.

Sohini Ghoshroy, PhD
Post-doctoral Researcher |
Research Interests: Sohini has been examining the molecular evolution of nitrogen assimilating enzymes in select algal lineages.  Her work has identified several instances of endosymbiotic and horizontal gene transfer events that have created chimeric enzymatic pathways in these lineages.  She is also working to characterize RNA binding proteins in diatoms that may be involved in the regulation of nitrogen assimilation.  More information regarding Sohini’s research and teaching interests can be found on her  webpage.

Katie Minnix, ClarkU ’12
Research Interests:  Katie was an ES&P major at Clark and is in the accelerated BA/MS program.  Working in collaboration with Prof. McGraw (Chemistry), Katie is looking at the impact of pH and dissolved inorganic carbon on the growth of marine diatoms.
