Biography: 

Dr. Jafar Razmi’s research focuses on engineering structures and infrastructural design and behavior under different types of load including transportation, environmental and other dynamic loads. He is interested in behavior of materials, fatigue and damage. He received his BS in Mechanical Engineering, MS. and PhD in Civil Engineering from University of Maryland at College Park. His work experience spans between academia and more than 12 years of industry in the areas of mechanical design, industrial construction and management, power station, Quality Assurance and Environmental Management Systems (EMS) auditing in industrial design and process. He is also interested in Additive Manufacturing (AM) and its applications in design and fabrication of new materials and structures, Process optimization for additive manufacturing of metals and experimental evaluation of thermal characteristics of metallic powder at different temperatures.
