B.Sc. Azad University, Science and Research Branch, Tehran, Iran (2010)

M.Sc. Shahid Beheshti University, Tehran, Iran (2013)

Ph.D. University of Bonn, Germany (2018)


I was born in Gorgan, Iran and completed my bachelor's degree in physics at Azad University, Science and Research Branch, Tehran, Iran. Then, I pursued my master's studies at Shahid Beheshti University in Tehran, Iran, graduating in 2013. Seeking further academic growth, I embarked on a journey to Germany in 2014 to pursue a PhD in theoretical physics at the University of Bonn. Throughout my PhD, I studied the implications of low reheating temperature scenarios on the production of dark matter. Upon completing my PhD in October 2018, I started a postdoctoral research position at Goethe University Frankfurt. This experience allowed me to delve deeper into my field and expand my scientific contributions. Then for my second PostDoc I joined the Univeristy of Padua, Italy, in December 2020. Presently, I am a Postdoctoral Researcher at the University of Oklahoma, having joined in April 2023. Throughout my research, I have explored various topics within particle physics and cosmology including dark matter, gravitational waves, axions, and primordial black holes, etc.
