Dr. Sadegh's early research work was in the field of robotics and automation. His major contribution to this field was the development of a class of adaptive and learning controllers for nonlinear mechanical systems including robotic manipulators. This work, which evolved from his doctoral research, enables a robot to learn a repetitive task through practice, much like a human being, and without requiring a precise model. He later demonstrated that implementing this learning controller can significantly improve the performance of industrial robots without significantly increasing their cost or complexity, and has the potential to improve the accuracy, autonomy, and productivity of automated manufacturing systems. In addition to robotics, he developed a similar learning controller for speed regulation of copier photoreceptors as part of a project sponsored by the Xerox Corporation. Dr. Sadegh began at Tech in 1988 as an Assistant Professor.

H. Jerry Qi is a professor and the Woodruff Faculty Fellow in the George W. Woodruff School of Mechanical Engineering at Georgia Institute of Technology. He received his bachelor degrees (dual degree), master and Ph.D. degree from Tsinghua University (Beijing, China) and a ScD degree from Massachusetts Institute of Technology (Boston, MA, USA). After one year postdoc at MIT, he joined University of Colorado Boulder as an assistant professor in 2004, and was promoted to associate professor with tenure in 2010. He joined Georgia Tech in 2014 as an associate professor with tenure and was promoted to a full professor in 2016. Qi is a recipient of NSF CAREER award (2007). He is a member of Board of Directors for the Society of Engineering Science. In 2015, he was elected to an ASME Fellow. The research in Qi's group is in the general area of soft active materials, with a focus on 1) 3D printing of soft active materials to enable 4D printing methods; and 2) recycling of thermosetting polymers. The material systems include: shape memory polymers, light activated polymers, vitrimers. On 3D printing, they developed a wide spectrum of 3D printing capability, including: multIMaTerial inkjet 3D printing, digit light process (DLP) 3D printing, direct ink write (DIW) 3D printing, and fused deposition modeling (FDM) 3D printing. These printers allow his group to develop new 3D printing materials to meet the different challenging requirements. For thermosetting polymer recycling, his group developed methods that allow 100% recycling carbon fiber reinforced composites and electronic packaging materials. Although his group develops different novel applications, his work also relies on the understanding and modeling of material structure and properties under environmental stimuli, such as temperature, light, etc, and during material processing, such as 3D printing. Constitutive model developments are typically based on the observations from experiments and are then integrated with finite element through user material subroutines so that these models can be used to solve complicated 3D multiphysics problems involving nonlinear mechanics. A notable example is their recent pioneer work on 4D printing, where soft active materials is integrated with 3D printing to enable shape change (or time in shape forming process). Recently, his developed a state-of-the-art hybrid 3D printing station, which allows his group to integrate different polymers and conduct inks into one system. Currently, his group is working on using this printing station for a variety of applications, including printed 3D electronics, printed soft robots, etc.

bojan.petrovic@gatech.edu

Bojan Petrovic joined Georgia Tech in 2007 as a Professor. Prior to that he acquired industrial experience as a Fellow Scientist in Westinghouse Science and Technology where his primary responsibility was as the project Deputy Director on the development of the advanced, modular IRIS reactor.

Dr. Petrovic's current research focuses on advanced reactor design, nuclear fuel cycle and waste management, and related modeling and simulation methods.

Over the past ten years, he has been involved in the development of the IRIS Reactor, within an international team of 19 organizations from ten countries. IRIS is an advanced medium power (335 MWe) integral-type PWR, based on proven light-water technology, but incorporating many innovative solutions that improve its operation, safety, security, and economics. Advanced reactors have the potential to offer full benefit in synergy with advanced fuel cycles. Recently, the focus of this research is shifting to judicious selection of fuel cycle, reprocessing, and partition and transmutation options, which  may significantly reduce the radiotoxicity of spent nuclear fuel and enable its safe and economical ultimate disposal.

Novel reactor designs and advanced fuel cycles pose new challenges and require improved, more accurate methods of modeling and simulations. Dr. Petrovic's interest is in developing approaches for using Monte Carlo and hybrid deterministic-Monte Carlo methods (for eigenvalue as well as shielding applications) in a way that will be practical and relevant for analysis of complex nuclear systems.

Dr. Petrovic has a strong interest in interdisciplinary areas, and his research projects have included collaboration related to industrial and medical applications of nuclear technology. His recent research in computational medical physics focuses on proton therapy. His research has been sponsored by the Department of Energy, industry and utilities.

Oliver Pierron joined Georgia Tech in summer 2007. Prior, he was a senior engineer at the R&D center of Qualcomm MEMS Technologies, Inc. in San Jose, California. Pierron's research group investigates the mechanical properties of small-scale materials with emphasis on the degradation properties (fracture, fatigue, creep). The scientific contribution of this research is to develop a fundamental understanding of the degradation mechanisms at the nanoscale while the engineering motivation is to assess and predict the structural reliability of devices and systems fabricated with emerging technologies. An underlying challenge is to develop experimental techniques that permit to accurately measure these properties. Pierron's research is currently sponsored by the National Science Foundation.

Neu's research involves the understanding and prediction of the fatigue behavior of materials and closely related topics, typically when the material must resist degradation and failure in harsh environments. Specifically, he has published in areas involving thermomechanical fatigue, fretting fatigue, creep and environmental effects, viscoplastic deformation and damage development, and related constitutive and finite-element modeling with a particular emphasis on the role of the materials microstructure on the physical deformation and degradation processes. He has investigated a broad range of structural materials including steels, titanium alloys, nickel-base superalloys, metal matrix composites, molybdenum alloys, high entropy alloys, medical device materials, and solder alloys used in electronic packaging. His research has widespread applications in aerospace, surface transportation, power generation, machinery components, medical devices, and electronic packaging. His work involves the prediction of the long-term reliability of components operating in extreme environments such as the hot section of a gas turbine system for propulsion or energy generation. His research is funded by some of these industries as well as government funding agencies.
