My research interests are in carbon metabolism of algae and plants with an emphasis on CO2 fixation and respiration and how their interaction impacts secondary metabolism. I prefer to take a holistic approach to studying photosynthetic function by conducting measurements of CO2 and O2 exchange concurrently with electron transport, enzyme kinetics, metabolite pool sizes, and trace gas emissions. At UNM, I have focused my efforts on fast, automatable approaches that can be used to disentangle complex physiological processes in vivo, both to study dynamic processes and to create new tools for screening physiological function in genetically modified organisms. I am now advancing the automation of approaches in controlled environments for following function over diurnal cycles and also taking my methods into field settings to generate an unprecedentedly detailed picture of photosynthetic and respiratory function in natural and artificial ecosystems.
