I am a plant developmental geneticist interested like most biologist in the diversity of life. My current work focuses on how plants sense and respond to the ever changing environment. This is essential in allowing plants to adapt to new niches. I am particularly interested in exploring what facilitated the niche transition of grasses, which originated in the tropics to the temperate zone.

I am currently a Howard Hughes Medical Institute Postdoctoral Fellow of the Life Sciences Research Foundation, 2018-2021.


Research Interests

            A fundamental question in biology is to understand how the information encoded within a genome interfaces with the environment to create a range of possible phenotypes, and our understanding of this is in its infancy. The long-term goal of my research is to understand the molecular mechanism by which environmental cues are perceived and translated into various phenotypes. Given the sessile lifestyle of plants, evolutionary adaptation has favored plasticity in growth and development so that plants can thrive in changing environments. Therefore, plants are an excellent group of organisms in which to study the molecular basis of how environment influences phenotype, which will be vital to understand as global climate changes.

The transition from vegetative to reproductive development is a key decision for which the timing is often directly influenced by the environment. This critical life history trait has been shaped over evolutionary time to maximize the ability to flower at a time that optimizes reproductive success, and it has a profound influence on the appearance of plants. In global crops, such as wheat, the timing of this transition has been modified multiple times as wheat expanded through multiple environments across the globe. Furthermore, timing of flowering is one of many traits that have been manipulated by humans for increased crop productivity. Thus, the study of flowering-time is not only a fascinating topic from a basic research standpoint, but also has relevance for crop improvement particularly in a changing global climate and a growing human population. I aim to focus my flowering-time studies in Poaceae (grasses), a group of plants that dominate many ecologically important habitats throughout the world, provide for most of our species caloric intake with crops such as rice, wheat, corn, oats, barley, sorghum, and rye and, in the future, may provide a major part of a sustainable biomass energy portfolio.

            During my graduate work, I focused on establishing the temperate grass Brachypodium distachyon as a flowering-time model and I plan to continue to use this model grass to accelerate gene discovery. B. distachyon is a useful model grass because of its small, completely sequenced diploid genome, simple growth requirements, large collection of accessions, inbreeding nature, ease of transformation, and high rate of recombination. The focus of my post-doctoral studies will be to expand my work into crops with a focus in wheat.

            Broadly, I aim to understand how day-length and temperature influences time to flower; i.e., how these environmental signals are sensed and how this information is integrated to direct development. The long-term goal of this project is to provide a better understanding of the regulatory gene networks responsible for the integration of both photoperiod and temperature signals in the temperate cereals by doing comparative work between B. distachyon and wheat.
