About me

I am a Lecturer (Assistant Professor) in Data Science/Artificial Intelligence at the University of Stirling. I received the Ph.D. degree in physics with a specialisation in radar remote sensing and data analytics from the UiT—The Arctic University of Norway, Tromsø, Norway, in 2013.

I receieved a MSc. degree (with Honors) in Earth Observation at University of Tehran, 2006-2009.

Since 2014, I continued my research in radar remote sensing and machine learning as a Post-Doctoral Research Fellow with the UiT—The Arctic University of Norway, the Norwegian Institute of Bioeconomy Research, and the University of Stirling.

I have been a Visiting Scientist with the Signal Processing and Telecommunications Laboratory, Department of Electrical, Electronic, Telecommunications Engineering and Naval Architecture, University of Genoa, Genoa, Italy, in 2011, and a Visiting Researcher with the German Geoscience Center (GFZ), Potsdom, Germany, in 2008. I was an Assistant Professor with the University of Tehran in 2015.

I am also a Council Member of the Remote Sensing and Photogrammetry Society (RSPSoc), U.K.

My primary research interests revolve around the intersection of radar remote sensing and statistical modelling/machine learning, with a particular focus on the applications in environmental monitoring.

Research (1)

My research interests lie at the intersection between machine learning and Earth Observation for environmental monitoring. Specifically, I have focused on the applications of Interferometric SAR (InSAR) for land subsidence monitoring and Polarimetric SAR (PolSAR) for target detection, change detection, and land cover classification. Additionally, my work involves developing novel methods in machine learning, signal and Image processing, and data analytics for multidimensional SAR data. Furthermore, I am actively engaged in the field of big Earth data analytics with SAR for forestry, glaciology, and agriculture monitoring. In summary my research is focused on the following area:

• Artificial intelligence for Earth Observation (AI4EO)

• Big EO data analytics

• Advanced InSAR and PolSAR techniques for environmental monitoring.

I am a member of the Data Science and Intelligent Systems (DAIS) Earth and Planetary Observation Research Groups. I am also a member of the Stirling Vision and Image Processing Group (SVIP).
