Tequila A. L. Harris is a Professor in the George W. Woodruff School of Mechanical Engineering, and is the director of the Highly Advanced Roll-to-Roll iManufacturing Systems (HARRiS) group. Her research focuses on investigating the fundamental science associated with manufacture of polymer thin films from fluids (e.g., solutions, dispersions, slurries, etc.) as they are coated onto permeable or impermeable surfaces to make components or devices. She explores the connectivity between thin film functionality, based on their manufacture or structure, and their life expectancy, to elucidate mechanisms by which performance or durability can be predicted. In addition to conducting computational analysis, developing analytical models and running experiments, Harris also develops new manufacturing technologies to fabricate thin films, in wide area or discrete patterns. Target applications are well-suited for a variety of industries including food, energy, electronic, and environmental systems to name a few. In conjunction with her research activities, she is committed to the education, mentoring, and advisement of students towards scholarly achievements. She has published over fifty peer-reviewed articles. Harris has several awards including the National Science Foundation's young investigator CAREER Award and the Lockheed Inspirational Young Faculty Award.

Julien Meaud joined Georgia Tech as an Assistant Professor of Mechanical Engineering in August 2013. Before joining Georgia Tech, he worked as a research fellow in the Vibrations and Acoustics Laboratory and in the Computational Mechanics Laboratory at the University of Michigan, Ann Arbor. 

Dr. Meaud investigates the mechanics and physics of complex biological systems and the mechanics and design of engineering materials using theoretical and computational tools. 

One of his research interests is auditory mechanics. In this research, he develops computational multiphysics models of the mammalian ear based on the finite element method. The mammalian ear is a nonlinear transducer with excellent frequency selectivity, high sensitivity, and good transient capture. The goal of this basic scientific research is to better understand how the mammalian ear achieves these characteristics. This research could have important clinical applications as it could help in the development of better treatment and the improvement of diagnostic tools for hearing loss. It could also have engineering applications, such as the design of biometic sensors. This research is truly interdisciplinary as it includes aspects of computational mechanics, structural acoustics, nonlinear dynamics, biomechanics and biophysics. 

Dr. Meaud is also interested in the mechanics, design and optimization of composite materials, particularly of their response to cyclic loads. Tradtional engineering and natural materials with high damping (such as rubber) tends to have low stiffness. However, the microarchitecture of composite materials that consist of a lossy polymer and a stiff constituent can be designed to simultaneously obtain high stiffness and high damping. Using computational tools such as finite element methods and topology optimization, the goal of Dr. Meaud's research is to design composite materials with these unconventional properties. One of his future goal is to extend the design of these materials to the finite strain regime and high frequency ranges, in order to obtained materials tailored for the targetted application. This research includes aspects of mechanics of materials, computational mechanics and structural dynamics. 

In Dr. Meaud's research group, students will learn theoretical and computational techniques that are used extensively to solve engineering problems in academic research and industry. Students will develop knowledge and expertise in a broad array of mechanical engineering areas. The knowledge that students will gain in computational mechanics, nonlinear and structural dynamics, structural acoustics, dynamics and composite materials could be applied to many domains in their future career.

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.

Valeria Tohver Milam joined the School of Materials Science and Engineering at Georgia Institute of Technology as an assistant professor in July 2004. She received her B.S. in Materials Science and Engineering with Honors from the University of Florida in 1993. After completing her M.S. degree (1997) in MSE at the University of Illinois, Urbana-Champaign, she interned at Sandia National Laboratories. She then completed her doctoral work at UIUC studying the phase behavior, structure and properties of nanoparticle-microsphere suspensions. Experimental results suggested a novel colloidal stabilization mechanism known as nanoparticle “haloing” in which otherwise negligibly charged microspheres become effectively charge-stabilized by their surrounding shell of highly charged nanoparticles.

After finishing her Ph.D. in 2001, her postdoctoral studies at the University of Pennsylvania focused on DNA-mediated colloidal assembly. The degree of specific attraction between DNA-grafted microspheres was found to vary with sequence length, sequence concentration and ionic strength. A variety of structures such as colloidal chains, rings and satellites were formed by varying the particle size ratio and suspension composition.
