My research focus is on plant eco-physiological responses to changes in water availability (spatially, temporally, or driven by climate changes). Particularly, I'm interested in the mechanims of drought tolerance by grassland and savanna species (structure / function) as well as the theory of competition/ facilitation for water between trees and grasses. Thus, I enjoy spending my time addressing questions linking resource availability - physiology - patterns of productivity, with the goal of improving our ability to scale energy dynamics and hydrological processes from the plant- to ecosystem-level.

I love spending time outdoors in the grasslands. These systems exist within an interface of climatic variability and frequent disturbance (fire and grazers). Grass species are deceptively simple, but their unique physiology and form is adapted to environmental stress and disturbance. Despite abiotic and biotic pressures, grasses are masters of growth efficiency and develop dense canopies and high biomass. The environmental and biotic complexity of grasslands provides a challenging (mentally and physically) and enjoyable system to study. For me, there is nothing better than spending a day in the sun of the Konza Prairie.

I would like to call myself an isotope hydrologist interested in understanding the hydrological processes in the soil-vegetation-atmosphere interface from the critical zone to the catchment and river basin scale. I employ stable isotopes (δ18O and δ2H) along with several other tools to trace the movement and transport of water in different hydrological compartments. I am from Kerala, the southernmost state of India blessed with the tropical vegetation cover of Western Ghats, a biodiversity hotspot. The vegetation was supported by copious rainfall (≈3000 mm annually), but with every passing year, the monsoon rainfall patterns have been witnessing drastic change- both in the form of extreme floods and drought events. This made me wonder about the water cycle changes associated with these extreme events. Hence, during my PhD, I studied the changes in surface water and groundwater circulation processes associated with weather fluctuations and the role of moisture recycling in producing rainfall. Soon, I wanted to explore how the water uptake strategies of plants are affected by these extreme events. For this, I have worked at the prestigious Physical Research Laboratory, India with a National Post-doctoral Fellowship.

I look forward to working at KSU to understand the impact of woody encroachment on the hydrological cycle and the response of woody and herbaceous plants toward extreme events.

I was born and grew up in Iran. As a person who spent lots of her childhood in prairies with great enthusiasm to study plants, Kansas State University, with its magnificent environment in every aspect, is an academic place that I always wanted to join one day. I’m here to extend my knowledge in Ecophysiology and fill the gap between this field of study and Plant Biochemistry. Isn’t it great?! Based on my background in Plant Science, I have investigated the signaling transduction pathway of abiotic stress responses in plants. I'd like to dedicate my time to do more research on physiochemical mechanisms in plants subjected to drought and oxidative stresses to understand the biochemical basis of resistance in the context of Ecophysiology. Moreover, I am interested in unravelling the functions of particular byproducts regulating abiotic stress tolerance in C4 grasses. So, my PhD project would be a breathtaking linkage between Ecophysiology and Plant biochemistry. I’m already excited about it.

I'm a military child that decided to continue living here in Kansas for my undergraduate! I am currently pursuing my degree in Biology on the Animal Biology track, with plans to apply for vet school in the near future. I enjoy working with animals and would like to do animal physiology research to benefit animals in the future.
