David Flaherty, PhD is a Professor in the School of Chemical and Biomolecular Engineering at Georgia Tech since June 2023 (starting Summer 2023, previously at the University of Illinois, Urbana-Champaign). His research focuses on developing the science and application of catalysis in the pursuit of sustainability. In recent years, his group’s contributions have been featured in Science, Nature Catalysis, Journal of the American Chemical Society, ACS Catalysis, Journal of Catalysis and other prestigious journals. Dr. Flaherty has received several recognitions for excellence and innovation in catalysis including the Eastman Foundation Distinguished Lecturer in Catalysis, Department of Energy Early Career Award, and the National Science Foundation CAREER Award. Dr. Flaherty engages frequently with industry to translate the groups scientific achievements from the lab into practice. Through university-industry partnerships, the group has filed multiple patents disclosing synthesis of catalytic materials and development of processes. Beyond his research activities, Dr. Flaherty enjoys teaching topics in chemical engineering in the classroom (kinetics, separations, transport, reaction engineering) and mentoring the next generation of research leaders and educators.

Prof. Flaherty received his B.S. in Chemical Engineering from the University of California, Berkeley and his Ph.D. in Chemical Engineering from the University of Texas at Austin under the direction of Prof. C. Buddie Mullins. He conducted postdoctoral work at the University of California, Berkeley with Prof. Enrique Iglesia.

During my research career I have observed “new” material systems develop and offer promise of wondrous device performance improvements over the current state of the art. Many of these promises have been kept, resulting in numerous new devices that could never have been dreamed of just a few short years ago. Other promises have not been fulfilled, due, in part, to a lack of understanding of the key limitations of these new material systems. Regardless of the material in question, one fact remains true: Without a detailed understanding of the electrical and optical interaction of electronic and photonic “particles” with the material and defect environment around them, novel device development is clearly impeded. It is not just a silicon world! Modern electronic/optoelectronic device designs (even silicon based devices) utilize many diverse materials, including mature dielectrics such as silicon dioxide/nitrides/oxynitrides, immature ferroelectric oxides, silicides, metal alloys, and new semiconductor compounds. Key to the continued progress of electronic devices is the continued development of a detailed understanding of the interaction of these materials and the defects and limitations inherent to each material system. It is my commitment to insure that new devices are continuously produced based on complex mixed family material systems.

Colton's research interests are in the areas of design and manufacturing, focusing on polymers and polymer composites. Processing techniques, such as micro-molding, injection molding, filament winding, resin transfer molding and the like, are studied and used to fabricate these devices and products, such as smart composite structures.

The design of processing techniques and equipment for metamaterials also are being studied with applications being dielectric materials for electromagnetic applications. Due to the small-scale physics associated with their engineering, nano-scale metamaterials exhibit superior properties and enhanced performance.

Colton has a strong passion for the application of engineering for the common good – "humanitarian design and engineering" and "design that matters," - such as in developing countries and other resource limited environments. To be successful, multidisciplinary teams must work together to produce products that function as well as delight, that exceed customer's expectations, regardless of where the product is used. Along these lines, product design and role that the interactions between engineering and industrial design forms another research interest.

The main focus of Collard's research is the molecular self-assembly in polymers which allows for the formation of new supermolecular architectures that take on new functions and promise potential benefits and novel applications. Currently, his group is studying surfactants, spontaneously assembled monolayers, and liquid crystals. Materials under study include conjugated electronically conductive polymers and new functional polyesters. Techniques used to construct and probe the structure of our supramolecular assemblies including: synthesis, electrochemistry, thermal analysis, X-ray diffraction and microscopy.

Baratunde A. Cola is a professor in the George W. Woodruff School of Mechanical Engineering and the School of Materials Science and Engineering at the Georgia Institute of Technology. He received his degrees from Vanderbilt University and Purdue University, all in mechanical engineering, and was a starting fullback on the Vanderbilt football team as an undergrad. Cola has received a number of prestigious early career research awards including the Presidential Early Career Award for Scientist and Engineers (PECASE) in 2012 from President Obama for his work in nanotechnology, energy, and outreach to high school art and science teachers and students; the AAAS Early Career Award for Public Engagement with Science in 2013; and the 2015 Bergles-Rohsenow Young Investigator Award in Heat Transfer from the American Society of Mechanical Engineers. In addition to research and teaching, Cola is the founder and CEO of Carbice Corporation, which sells a leading thermal management solution for the global electronics industry.

Professor Citrin earned a B.A. from Williams College (1985) and a M.S. (1987) and a Ph.D. (1991) from the University of Illinois, all in physics, where his dissertation was on the optical properties of semiconductor quantum wires. Subsequently, he was a post-doctoral research fellow at the Max Planck Institute for Solid State Research, Stuttgart, Germany (1992-1993) and Center Fellow at the Center for Ultrafast Optical Science at the University of Michigan (1993-1995).
