Personal Overview

Dr. Mirmilad Mirsayar is a tenured Associate Professor of Aerospace Engineering in the Department of Aerospace, Physics, and Space Sciences at the Florida Institute of Technology (FIT). He has co-authored over 50 peer-reviewed journal publications and several conference proceedings papers. He has received several awards and recognitions to date, including World's Top 2% Researchers by Stanford University & Elsevier (2021 - 2026), Faculty Excellence Award for Research, Department of Aerospace, Physics, and Space Sciences (2024), and Outstanding Reviewer Awards from many prestigious journals in the field of solids and structures. His research has been supported by several federal agencies, including the National Science Foundation (NSF), the National Aeronautics and Space Administration (NASA), and the U.S. Department of Transportation (DoT). Before joining FIT, he served as a Postdoctoral Researcher and then as a Research Scientist in the Aerospace Engineering Department of Texas A&M University, working on several funded projects on advanced materials and structures, fracture mechanics & fatigue, and composite structures. He earned his Ph.D. degree from Texas A&M University in 2017.
