B.S, Agronomy, Penn State University, 1978
Research Areas Detail:

Sucrose trafficking with respect to growth and fitness of Populus

Sucrose partitioning and diurnal rhythms are orchestrated to maximize tree fitness. I am interested in the orchestration process and its plasticity in the face of environmental challenges.
