I. Joga Rao
Dr. I. Joga Rao is the Chair of the Department of Mechanical and Industrial Engineering. He joined the MIE department in 2000 after obtaining his Ph.D. in Mechanical Engineering from Texas A&M University. Prior to that, he obtained his M.S. from the University of California, Berkeley and B.Tech from the Indian Institute of Technology, Bombay. His research focuses on continuum mechanics and constitutive modeling. This includes the mechanics of fluids and solids, the modeling of non-linear phenomenon observed in mechanics with an emphasis on applications in polymers, manufacturing processes and biomechanics. Specific areas of research are: Shape Memory Polymers, Multi-Physics Polymer Systems, High Temperature Materials and Growth in Biological Tissues. His research has been supported through grants from the National Science Foundation, Department of Energy and the Air Force.
Prof. Rao has received numerous awards for his teaching. He has received the College of Engineering’s Excellence in Teaching Award and NJIT’s Excellence in Teaching Award. In addition he has received the Robert Van Houten Award from the Alumni Association of NJIT. Prof. Rao has been an Air Force Summer Faculty fellow twice.

My research focuses on continuum mechanics and constitutive modeling. This includes the mechanics of fluids and solids, the modeling of non-linear phenomenon observed in mechanics with an emphasis on applications in biomechanics, manufacturing processes and polymers. Specific areas include Shape Memory Polymers, High Temperature Materials and Growith in Biological Tissues.
- Modeling the mechanics of shape memory polymers. Shape memory polymers (SMP’s) are novel materials that can be easily formed into complex temporary shapes, retaining memory of their original shape even after undergoing large deformations. They can be made to return to their original shape through a suitable trigger. These triggers can range from heating, to change in pH, to exposure to light. We are currently developing models for glassy, crystallizable and light activated shape memory polymers. This research is funded by the National Science Foundation
- Modeling the inelastic behavior of single crystal Nickel based superalloys at elevated temperatures. Our work focuses on modeling the temperature dependent anisotropic creep response of single crystal superalloys within a full thermodynamic framework. This works is funded by the Department of Energy.
- Modeling of growth in biological tissues. The main thrust of this work is on developing mathematical models that can describe the process of growth and remodeling of biological tissues in response to different stimuli.
