Since my high school days I have developed strong interests for the issues regarding my living environment and planet earth, especially conservation of the natural resources, as I advocate the opinion ‘’ Earth is the only livable planet; just save it’’.  That is why I enrolled myself at the Ferdowsi University, where I graduated first in my class, with distinction at the program BA in watershed and rangeland management. I finished my master studies in University of Belgrade in Environmental engineering- Water and soil resources protection based on the research that I have conducted on the Erosion and torrential flood control in Iran. As I finished my master studies on hydraulic and hydrology systems and their interaction with the erosion. I moved to Vienna and started my research on weather radars and dynamic models for investigating the surface runoff behaviour and deriving thresholds for flood and debris flow with it. 
I have been working within Alpine studies department of Vienna, as an active researcher. Since April 2014 I started working on radar data analyses with ZAMG (meteorology department of Austria), where I gained precious experience in the field of estimating surface fluxes (especially latent fluxes in my case). This experience enabled me to be familiar with the energy balance calculation and to determine evapotranspiration in Palten valley. 
During my studies at the University of Belgrade, I have developed special interest for hydrology and simulation models. However, I wanted to combine those interests of mine as a Junior Researcher at the Alpine studies Institute, where I was doing my research. 

In October 2015 I started my project with EU comission in C-CASCADES project, working on the representation of lateral transfer of DOC from land to river system in JULES model, Primary Supervisor: Prof. P. Friedlingstein (UNEXE); Secondary Supervisors: Dr. B. Guenet and Prof. P. Ciais(CNRS-IPSL)

The current version of JULES, the land surface model of the Met Office Hadley Centre Earth system model does not account for export of carbon from terrestrial ecosystems to the aquatic environments. Runoff is represented in the model as river routing to the ocean, without including transfer of carbon. The aim of the project is to include a representation of DOC production in terrestrial soils, due to incomplete decomposition of organic matter, and its export to the river network by leaching. The model will be evaluated using river discharge DOC data for large rivers across the world, with a focus on a specific region (Arctic or Tropics). Simulations will be performed with the major historical forcing (climate, atmospheric CO2, nitrogen deposition, and land-use changes) in order to estimate the changes of DOC export and their attribution to anthropogenic activities.
