Aref Yadollahi, Ph.D.

Assistant Professor of Mechanical Engineering

Aref Yadollahi


Aref Yadollahi is an assistant professor in the Department of Mechanical and Civil Engineering. His research and teaching interests include additive manufacturing, fatigue and fracture mechanics, solid mechanics, and materials science.

Research Overview

My main research focus during the past few years has been on investigating the microstructural and mechanical properties of additively manufactured materials, quantifying their reliability, and developing tools for predicting their performance under monotonic and cyclic loading. My work in this area has been involved with a variety of laboratory tests and computational modeling techniques.

Just as a talented composer “hears” a sound before writing it down on the score, a good engineer should be able to visualize structures and processes – through a combination of rules, models, and instincts – where there’s nothing apparent. It’s not only about what one sees; it’s also about the unseen!

Previous Roles

Assistant Professor of Mechanical Engineering at the University of South Alabama (2020-2022).

Why I Became an Engineer

I became an engineer because an engineering degree can provide you with a career that has lots of freedom and excitement. As an engineer, you can work virtually in any field, even non-engineering fields!

What Engineers Can Do to Make a Difference

The real world is full of constraints that make or break potential. Engineers can bring dreams one step closer to fruition by finding the best possible solution under the given constraints. Taking this one step forward makes a huge difference!
