My passion for learning inspires me to continually take steps out of my comfort zone.”
Arman Moussavi
PhD Candidate in the Department of Civil and Environmental Engineering

Arman Moussavi is a PhD candidate in the Department of Civil and Environmental Engineering in the McCormick School of Engineering. He uses simulated nanoscopic models to research and identify the factors that determine a material’s properties like strength and elasticity. Arman is the recipient of the International Institute for Nanotechnology (IIN) Ryan Fellowship.
How would you describe your research and/or work to a non-academic audience?
My research focuses on understanding the fundamental principles of material properties: Why do materials behave like they do? Why are they strong, weak, tough, or brittle?
I use computer code and simulators to design models of materials at the nanoscopic level to provide a theory that explains the building blocks that determine their mechanical properties, such as strength and toughness.
Tell us what inspired your research and/or work.
My passion for learning inspires me to continually take steps out of my comfort zone. As a civil engineer, I’ve tackled projects that push me into unfamiliar fields, from polymers to artificial intelligence. I also draw inspiration from the evolving challenges of society stemming from my upbringing in a family full of civil engineers. From a young age, I developed a deep desire to contribute to a better and more sustainable future. Whether through educating future generations of engineers or designing innovative materials, I am inspired by the needs of my community to drive progress, foster sustainability, and develop creative solutions for the future.
Whom do you admire in your field and otherwise, and why?
I truly admire my PhD adviser, Dr. Sinan Keten. He is not only an outstanding academic mentor but also a role model in many aspects of life. His continuous care and support inspire me and his many students, constantly encouraging us to strive for excellence and make the best choices for our future.
Why Northwestern?
From my first Zoom call with the professor who would become my PhD adviser to the new people I meet every day, I have always felt a strong sense of community and support. I was initially drawn to Northwestern's strong interdisciplinary research and quickly realized that its success is made possible by the collaboration and dedication of its students and faculty.
How do you unwind after a long day?
I unwind by skateboarding, surfing, and playing sports like tennis and volleyball with friends. I also enjoy creative pursuits, such as playing the drums and piano, painting and pretty much anything else that sparks inspiration.
What advice would you give your younger self or someone considering a similar path?
Find what makes you happy, keep pushing towards that goal, and never give up on yourself. Although times can get tough, there would be no good without bad. Even if you are struggling, there is always a silver lining and an opportunity to grow.
What are you most proud of in your career to date?
I am most proud of the scope and breadth of my research. I never imagined studying the topics I do now, let alone publishing impactful articles based on my research. Giving my work to society in this way and knowing the positive impact makes me very proud.
