Overview

I have an appointment in the School of Plant and Environmental Sciences that includes 70% research, 20% teaching and 10% service. My research program is centered on elucidating the molecular and physiological mechanisms that regulate plant growth and development under normal and stressful environments and utilizing that knowledge to enhance crop productivity. I teach courses in plant biology and plant stress physiology.

Limited water availability is the major environmental factor constraining plant performance and crop yields. Therefore, feeding a growing human population requires collaborative efforts among plant biologists to harness plant genetic diversity for the targeted development of plants with improved drought tolerance and increased productivity under water deficit conditions. The over-arching goal of my research program is to elucidate the molecular and physiological mechanisms that regulate plant growth and development under normal and stressful environments and to utilize that knowledge to enhance crop productivity. I am applying modern molecular genetics and functional genomic approaches and establishing interdisciplinary and transdisciplinary collaborations to develop transformative approaches to study plant growth and development under water deficit stress.

My research focuses on the following specific questions:

  1. How is root growth regulated by changes in cell wall structure and composition, and how does water limitation impact these processes?
  2. What physiological mechanisms regulate sugar movement from source to sink tissues in plants grown under normal and water deficit conditions?
  3. What are the physiological processes involved in root-rhizosphere interactions, and how do these interactions benefit (or sometimes hinder) plant development and crop productivity under normal and stressful environmental conditions?
  4. How do plants integrate environmental signals with developmental programming to modify their structure and functions?
  5. How can we harness the power of plant genetic diversity to improve plant growth and crop productivity under normal and stressful environments?

To address these questions, I work with model and non-model plant and crop species, and the research is conducted across cellular, tissue and whole-plant scales. In the long-term, knowledge from these integrated studies will pave the way to promote stress-responsive growth and development in plants and optimize them for sustainable food and energy production.
