Employed By

UCLA / JIFRESSE

Biography

My research focus is on improving our understanding of important ecosystem processes such as gross production in response to changes in temperature and water cycle.

Education

  • PhD of Systems Ecology, University of Montana, USA
  • MA of Environmental Planning and Management, University of Tehran, Iran
  • BA of Natural Resource Engineering-Environment, University of Allame Mohades Noori, Iran

Professional Experience

  • Assistant researcher. UCLA Joint Institute for Regional Earth System Science & Engineering (2022-present).
  • Postdoctoral fellow. NASA- Jet Propulsion Laboratory (2018-2022).
  • Research scientist. NASA SMAP L4C product validation and maintenance. NTSG- University of Montana (2016-2018).
  • Graduate Research Assistant. NTSG, University of Montana (2011-2015).

Research Interests

The focus of my research is improving our understanding of important ecosystem processes such as gross primary production in response to changes in temperature and water cycle at global scales. Accelerated climate change including changes in temperature and precipitation patterns and extreme weather events are affecting ecosystems processes, leading to shifts in species distributions, changes in phenology, productivity, composition of plant communities, and other biogeochemical processes. Using remote sensing observations, modeling, ecological and biophysical measurements, my research goal is to understand the response of ecosystems to changes in water availability and temperature.
