I received my BSc and MSc in Mechanical Engineering with a strong focus on Urban Science from two prestigious universities in Iran (KNTU and TMU), and now, I am deeply honored to pursue my PhD at À¦°óSMÉçÇø, worldwide renowned as a leading university. My PhD research focuses on the interactions between thunderstorm winds and urban environments using computational fluid dynamics and/or the climatology of winds. In addition, an experimental campaign in Montreal using wind profilers and other weather observing instruments will be a part of the project. Highlighting the importance of my project, I should indicate that our world is dramatically moving towards urbanization. Therefore, the aspect of Atmospheric Science that concentrates on the Urban Environment plays a pivotal role in providing humans with a more sustainable living environment and in making a brighter tomorrow for our exquisite planet. Hence, I am genuinely enthusiastic about following my ambitions and broadening my background knowledge in computation-based Urban Science by benefiting from this PhD program.

Brief research description

• . My research interest lies in mountain meteorology, on how terrain influences the atmosphere. I am currently working on differentiating the organization of shallow orographic convection.

I am a Ph.D. student in the department of AOS since 2020, supervised by Prof. Daniel Kirshbaum. My current project focuses on understanding the key physical processes of convection initiation forced by mesoscale boundary-layer convergence lines (CLs). I'm trying to answer the scientific question of what makes CL more effective at triggering deep convection than ordinary boundary-layer turbulence. My research combines analysis of both observations and idealized/realistic modeling.

I am currently a PhD student in Atmospheric Sciences at À¦°óSMÉçÇø, working under the supervision of Professor Ariya. I began my doctoral studies in Fall 2023, focusing on air pollution, aerosols, and black carbon. My research involves using ground-based and satellite-based measurements, along with machine learning techniques, to analyze particulate matter (PM2.5) and aerosols in urban environments. In my first year, I conducted a comparative study of PM2.5 and aerosol data, leveraging both ground-based and satellite measurements to understand their behavior in different environmental conditions.

I earned my Master’s degree in Meteorology from the University of Tehran, where I graduated with distinction for my thesis work. During my Master’s, I was funded by À¦°óSMÉçÇø as a graduate trainee in Professor Ariya’s group, working on the observation of PM2.5 and co-pollutants in both warm and cold climate urban settings using a variety of machine learning algorithms. Prior to that, I completed my Bachelor’s degree in Physics at the University of Guilan.

Outside of my academic work, I enjoy cooking, walking, playing the piano, and riding my scooter. I am also passionate about communication and always excited to engage with others about science and research.
