- Studying the variation in populations of fungal pathogens of plants in natural and agricultural settings.
- Arsenic tolerance in the tropical fern Pteris vittata.
Dr. Lehman is a plant pathologist who studies the
ecological/epidemiological interactions between plants and their
pathogens (e.g., floral-infecting fungi and their hosts). He teaches
biology, plant biology, genetics and tropical ecology courses. His
research interest is in studying the variation in populations of fungal
pathogens of plants in natural and agricultural settings. In addition to
providing a better understanding of the biology of the pathogen
(population genetics and dynamics), information from such studies could
be applied to develop resistant host varieties. A second area of
research is arsenic tolerance in the tropical fern Pteris vittata. His
objective is to understand the role that arsenic hyperaccumulation plays
in the growth and reproductive biology of fern gametophytes. In
addition, he is interested in how arsenic hyperaccumulation might reduce
rates of herbivory and pathogen attack.
