Sprigle teaches design-related classes in both the Schools of Industrial Design and Mechanical Engineering.

Physiological and biomechanical mechanisms underlying fine motor skills and their adjustments and adaptations to heightened sympathetic nerve activity, aging or inactivity, space flight or microgravity, neuromuscular fatigue, divided attention, and practice in humans. He uses state-of-the-art techniques in neuroscience, physiology, and biomechanics (e.g., TMS, EEG, fMRI, single motor unit recordings, microneurography, mechanomyography, ultrasound elastography, and exoskeleton robot) in identifying these mechanisms.

 In August 2023, Krishnendu Roy joined Vanderbilt University as the Bruce and Bridgitt Evans Dean of Engineering and a University Distinguished Professor in Biomedical Engineering, and Pathology, Microbiology, and Immunology, with a secondary appointment in Chemical and Biomolecular Engineering.

Previously, Roy served as Robert A. Milton Endowed Chair for the Coulter Department of Biomedical Engineering at Georgia Tech. He is also the former Director of the NSF Engineering Research Center (ERC) for Cell Manufacturing Technologies (CMaT), Center for ImmunoEngineering at Georgia Tech, and Marcus Center for Therapeutic Cell Characterization and Manufacturing. 

His overall research interests are in developing novel concepts for stem cell engineering as well as polymer controlled delivery of biological factors, especially for nucleic acid therapeutics (DNA, SiRNA and oligos) and immunoengineering. Currently, his group is involved in the following major areas of research; (a) Developing novel concepts to produce biodegradable surface functionalized micro-and nanoparticles for targeted and sustained delivery of nucleic acids, proteins, peptides and other immune modulators. In particular he is interested in developing multi-agent vaccine delivery systems for cancer and infectious diseases as well as immunotherapies for autoimmune diseases. (b) Creating spatio-temporally patterned polymer scaffolds for directed compartmental differentiation of stem cells into multiple lineages. (c) Engineering an artificial thymic niche for directed differentiation of stem cells into functional, antigen- specific T cells. (e) The development of novel nanoimprinting techniques to generate shape specific, environmentally triggered drug nanocarriers.

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.
