Dave is a world leading expert in the bioenergetics of photosynthesis. His research aims to understand how the biophysical and biochemical machinery of photosynthesis works in living systems, how it powers and shapes life, and how it might be altered to increase productivity in a changing environment. To approach this goal, his lab has invented and developed a series of next-generation high-resolution and high-throughput spectroscopic tools to characterize photosynthetic processes as they occur in vivo, and has pioneered an approach known as phenometrics, employing transformative phenotyping technologies to gain a far greater understanding of photosynthesis in vivo. Dave has developed a novel phenotyping system that provides an unprecedented level of detail for phenotyping photosynthetic mutants under fluctuating environmental conditions. This work has led to the identification of multiple novel genes involved in photosynthesis. Recently, his work led to the establishment of Michigan State University’s Center for Advanced Algal and Plant Phenotyping (CAAPP), a large-scale multi-disciplinary and multi-user facility to phenotype photosynthetic processes under natural environmental conditions. Dave received his B.S. in Biology from the University of Dayton and his Ph.D. in Biophysics from the University of Illinois at Urbana-Champaign with Antony Crofts, followed by post-docs at the Institute de Biologie Physico-Chimique, Paris with Pierre Joliot and the University of Freiburg, Germany with Wolfgang Nitschke. He was a faculty member at the Institute for Biological Chemistry at Washington State University from 1996 until 2010 and currently holds the title of Hannah Distinguished Professor at the MSU-DOE Plant Research Lab at Michigan State University.
