Professor Asaph Cousins Asaph is Associate Professor of Plant Metabolism. His research couples plant physiology and mathematical modeling of photosynthesis to understand the mechanisms controlling plant-environment interactions. The research uses a variety of techniques, including field experiments, leaf and whole plant gas exchange, biochemistry, and metabolite analysis to elucidate the mechanisms influencing the efficiency of C4 photosynthesis in response to changing environmental conditions.

GerryProfessor Gerry Edwards Gerry is Regents Professor of Plant Biology. His primary research focus is on photosynthesis, including investigations into the effects of environmental stress and potential global climate change. Studies range from the cellular to the whole plant level and include research into the mechanisms and evolution of carbon assimilation in C4, C3 and CAM plants. Gerry is an elected Fellow of the American Association for the Advancement of Science.

RitaDr. Rita Giuliani Rita is currently a postdoc in the Cousins Lab at WSU. She received her PhD in Ecophysiology from the University of Bologna, Italy. She has experience in plant physiology, biochemistry, photosynthesis and CO2 isotope exchange. Her current research involves photosynthetic, physiological and enzymatic characterization of transgenic rice lines which have had various C4 traits introduced into them.

Allison KolbeAllison Kolbe Allison got her undergraduate degree from Ohio Wesleyan University and is now a PhD student in the Cousins lab. Her research focuses on the enzymatic components of the C4 pathway that contribute to overall resource-use efficiency. Specifically, she is investigating the role and function of carbonic anhydrase in the C4 pathway. Prior to joining the Cousins lab, she worked at the Donald Danforth Plant Science Center studying the evolution of carbonic anhydrase across the grasses.  Her role in the C4 rice project is to characterize photosynthetic traits in transgenic rice lines.
