Abstract: Smart materials possess the ability to change their intrinsic physical properties in a specific manner in response to certain stimulus input and in a functionally useful manner. The stimuli could be pressure, temperature, electric and magnetic fields, or chemicals, and the associated changeable physical properties could be shape, stiffness, viscosity or damping. The field of smart materials has received great attention in the last decade due to an increasing awareness in materials capabilities, development of new transducer design, and increasingly stringent specifications in aerospace, automotive, biomedical and nano systems. Equally important for the advancement of the field are the development of models, numerical approximation techniques and control design that incorporate the nonlinear behavior of these materials.

Short Bio: Anirban Chaudhuri received his PhD from the University of Maryland at College Park in 2008. His doctoral dissertation focused on compact smart material based actuators and was supported by the US Army and Office of Naval Research. He has 14 journal papers and several conference presentations on topics ranging from parameter estimation in magnetorheological fluids to modeling of magnetostrictive driven actuators, and regularly reviews papers for leading publications on smart materials. Dr. Chaudhuri is currently a Research Scientist at the Los Alamos National Laboratory where he is developing ultrasonic sensors and vibration energy harvesters for the oil and gas industry. His patent on a two-phase fluid composition sensing was licensed to Chevron Inc. and has been implemented in an industrial meter. In addition to smart materials, he also has research interests in mechatronics, alternative energy, flow modeling, and nonlinear control theory.
