I was born and brought up in India where I earned my Bachelors in Agricultural Sciences from Punjab Agricultural University (2008-12). During my M.S. in Plant and Environmental Sciences from New Mexico State University, NM (2012-14), my research was mainly focused on the physiology of chile pepper plants under drip irrigated partial root zone drying (water management practice). I worked with various soil moisture sensors and meteorological sensors for irrigation management. My current project in Dr. Reinhardt’s lab is to quantify the carbon and water fluxes in three dominant tree species (juniper, Douglas fir, aspen) in the Reynolds Creek Critical Zone Observatory and in different species and subspecies of sagebrush along an elevation gradient using sap flux sensors, litter fall traps and automated dendrometers. This will allow us to quantify aboveground inputs of carbon to the soil at leaf to ecosystem scales.
My research focuses on measuring water and carbon fluxes from leaf to ecosystem scales in three sagebrush communities situated along an elevation gradient at Reynolds Creek Critical Zone Observatory in Southwestern Idaho. Sagebrush steppe ecosystems are one of the most extensive ecosystems in western North America, consisting of several different types of sagebrush communities. These communities survive under various climatic conditions based on their locations using different mechanisms to control carbon and water fluxes. With changes in climate, these communities will also have different responses to such perturbations. Thus, my focus will be to observe fluxes of three different sagebrush communities under varied microclimate conditions and dominant vegetation caused by an elevation gradient. I will also quantify how carbon and water fluxes vary at leaf, plant and ecosystem scales.
