My primary research interests are in the physiological and
molecular mechanisms of plant interactions with the physical environment. Past research subjects have included air
pollutant injury, root cell plasticity in response to nutrient deficiency,
plant behavioral movements in response to light and temperature, and plant
response to global change (elevated CO2). Currently my program is focused on understanding
the physiological and genetic basis for within-species variations in
phenological traits such as spring bloom.
Despite being one of the most dramatic landscape and ecosystem events of
the annual cycle, very little is known about the physiological and genetic
regulation of dormancy in perennial species. My group has employed classical
genetics and modern genomics to uncover important regulators of the
developmental events associated with growth cessation, bud formation and
endodormancy development. Our approaches
have made use of recent advances in high-throughput sequencing technology for
global gene expression and molecular marker development.
