    Expertise

    David Becker employs biochemical and biophysical methods to study extreme temperature effects on photosynthesis and mechanisms that plants employ to tolerate them. In particular, he studies a local desert plant, the creosote bush (Larrea tridentata), that is particularly well adapted to tolerate high temperatures.

    In addition, he collaborates with a colleague at Canisius College in Buffalo, NY, on a project that examines the photosynthetic properties of some plants with altered steroid contents.
