Bio

Dr. Venkataraman, Professor of Aerospace Engineering is an expert in the Analysis and Design of Aerospace Structures, Structural Optimization, Uncertainty Quantification, and Risk Assessment. His current research investigates models for failure prediction in aerospace composite structures, techniques for design optimization; design approaches for damage tolerance and predictable failure, use of surrogate models for multi-level optimization, reliability based design optimization, and quantification of variability and model uncertainty in complex multi-scale problems. His research is funded by NASA, Air Force, Navy, and Northrop Grumman.

Dr. Venkataraman teaches graduate and undergraduate level courses in solid mechanics, aerospace structural analysis and optimization. Courses taught in recent years include Statics, Aerospace Structural Analysis, Structural Vibration Analysis, Finite Element Structural Analysis, Mechanics of Composite Materials, Theory of Elasticity, Structural Optimization, & Theory of Elastic Stability. He has mentored several doctoral, masters and undergraduate students.
