Interests

Responses of plants to flooding

  • Environmental factors influencing species zonation in estuaries and wetlands
  • Physiological, biochemical, and anatomical factors influencing flooding tolerance in plants
  • Effects of low oxygen levels on respiration and nitrogen assimilation in plants
  • Roles of flooding tolerance in the success of wetland invasive species
  • Novel capabilities of plants beneficial to agriculture and phytoremediation

Effects of environment on photosynthesis in plants

  • Effects of drought and salinity on stomatal conductance, photosynthesis, and transpiration
  • Physiological, biochemical, and anatomical factors influencing drought and salinity tolerance in plant
  • Roles of latent, sensible, and radiative heat exchange under changing environmental conditions
  • Physiological and biochemical responses to oxidative stress in plants
  • Carbon and hydrogen isotope discrimination in photosynthesis and transpiration
  • Effects of chilling on photosynthetic light harvesting, gas exchange, and carbon metabolism

 

My research involves investigating physiological, biochemical, anatomical, and biophysical adaptations that enable plants to live under conditions of environmental stress. Much of my earlier work focused on responses of wetland and estuarine plants to conditions of flooding and salinity. During my graduate research, I studied how estuarine Spartina grasses (Poaceae) tolerate coastal mudflat conditions. I identified several physiological and biochemical features that contribute to flooding tolerance and estuarine zonation, including internal oxygen transport, anaerobic respiration capacity, aerobic demand, and oxygen affinity. Since then, my students and I have expanded my work to investigate processes in other systems. My students are now working on projects to characterize species zonation in freshwater wetlands, mechanisms of flooding tolerance in freshwater plants, effects of drought on prairie grasses, effects of creek drying on riparian plants, effects of oil well brine on plant productivity, and nitrate assimilation in wetland plants. Our work is helping to characterize general mechanisms of drought or waterlogging tolerance across plants, including other economically important crop species or ecologically relevant systems like wetlands.

Student Involvement

My work is well-suited for student involvement, and I have always involved students in my work. Students can gain valuable lab/field experience and ″hands-on″ learning, and I am happy for the help in the lab or field. If you are a current FHSU student and are interested in work similar to what is described here, feel free to contact me to discuss the possibility of work in my lab. Feel free to get in touch to discuss possibilities.
