Upon completion of my Bachelor’s degree in power engineering, I embarked on a career in the cement industry, where I spent more than four years to deepen my academic knowledge and gain experience in designing power and control systems.

As I did not feel quite satisfied with my theoretical knowledge, I started a Master’s degree at Shahid Beheshti University, Tehran, and I researched the various aspects of bipolar-type DC microgrids.  In 2015, I finalised my Master’s thesis and submitted several peer-reviewed papers on the voltage regulation and small-signal stability of bipolar DC microgrids.

I joined the InnoDC project in Spring 2018 with the research topic that revolves around the advanced control system design for multi terminal DC grids (MTDC).  I work on the control system of multilevel converters (MMC) while considering the dynamics of DC grid, AC grid, cables, DC-DC converters, and other components of MTDC. My supervisors are Oriol Gomis-Bellmunt and Eduardo Prieto Araujo.
