During my undergraduate studies, I worked at the Multidisciplinary Design Optimization Lab (later Space Launch Research Centre) at K. N. Toosi University of Technology from 2007 to 2010, working on developing optimization tools and system models for preliminary sizing of space launch systems. I did an internship at the Space Systems Research Center (SSRC) at KNTU, where I worked on the preliminary sizing of liquid propellant rockets. This led to my undergraduate thesis on the preliminary sizing of launch vehicles, titled "A Computational Model for the Conceptual Design and Preliminary Sizing of Multistage Expandable Space Launch Vehicles".
