Symposia

I spent 26 and a half years at Sandia National Laboratories in Livermore, CA where I retired at a level designated as "Distinguished Member of the Technical Staff" immediately before beginning at MSU in the fall of 2007.

During my 29 years work experience at the national labs, university and industry, I was able to manage and secure external funding up to $104.75 million (projected in 2009-11). Some of my funding agencies include National Science of Foundation (NSF), US Department of Energy (DOE), US Department of Transportation (DOT), Oak Ridge National Lab, US Department of Defense, and US TACOM.

I have been involved in the application of these types of material models to manufacturing processes such as forging, forming welding, heat treatment and distortion and in particular the importance of accurate physically based modeling in predicting the material evolution during a multi-stage series of manufacturing processes of these types. My interests also include the utilization of differential geometry in the description of crystal defects to develop generalized continuum models capable of describing processes at the micro and nano level. My first major assignment was to develop and implement a temperature and strain rate dependent plasticity model to predict material state and failure in the B83 energy mitigating nose cone. This analysis was the first large scale three dimensional finite element simulation and appeared on the cover of �Discover Magazine� and the cover of John Zukas �Impact Dynamics� book. This was also the birth of �the Bammann Plasticity Model� that later became �the Bammann-Chiesa-Johnson (BCJ) Plasticity/Damage Model� that is the core foundation of research at the Center for Advanced Vehicular Systems (CAVS) at Mississippi State University (MSU).

I organized four major international symposiums on various topics related to metals and polymers at Sandia National Labs. I also organized symposia and was chair/co-chair as part of more than 100 international conferences. I have been reviewer for more than 15 international journals and I am on editorial board of prestigious journal the Archive of Mechanics. Apart from this, I have given numerous invited lectures at various universities, national labs, and industries. At the later part of my career at Sandia, I was invited to give the plenary lecture at the 2005 combined meeting of the ASME, ASCE and SES. In 2008, I was bestowed with the honor of a Fellow of the ASME and am currently nominated to become a Fellow of the American Academic of Mechanics.
I have taught graduate courses in �Continuum Mechanics�, graduate courses in �Inelasticity�, and developed and taught a graduate level course in �Advanced Inelasticity�, which I will teach again in Spring of 2010. I continue to advise undergraduate (1), graduates (2 MS, and 4 PhD), post-doc fellows (2), and research professors (4) in various projects. I have been interacting with various other research faculties, post-doc fellows, and PhD. Graduate students at CAVS. Also, I have had the privilege of continued consulting with Sandia National Lab.

In the year 2000, I led a team that won the prestigious R&D 100 research award on microstructure based modeling of manufacturing processes.
