Philip Santangelo is a professor in the Wallace H. Coulter Department of Biomedical Engineering at Georgia Tech School of Engineering and Emory University School of Medicine. He is a member of the Cancer Immunology Research Program at Winship Cancer Institute. 

Dr. Santangelo obtained his Ph.D. in Engineering from the University of California at Davis. He completed his postdoctoral training at Sandia National Laboratories in Livermore, California and at Georgia Tech in Atlanta, Georgia. He also holds an MS in Engineering from Purdue University. 

The overarching theme of the Santangelo lab is the spatial biology of RNA viruses and RNA regulation. Spatial biology is the study of biology in three dimensions — and the Santangelo lab develops advanced imaging tools to achieve this goal. The lab focuses their tools on the spatial biology of HIV/SIV and human respiratory synctial virus (leading cause of bronchiolitis and pneumonia in babies) and the aberrant regulation of messenger RNA during inflammation, viral infections and cancer pathogenesis. They have developed both single molecule methods and whole body imaging methods in order to work towards our goals.

Khalid Salaita is the Samuel Candler Dobbs Professor of Chemistry, and Director for Graduate Studies in the Chemistry Department at Emory University in Atlanta, Georgia (USA). Khalid grew up in Jordan and moved to the US in 1997 to pursue his undergraduate studies at Old Dominion University in Norfolk, Virginia (USA). He worked under the mentorship of Prof. Nancy Xu studying the spectroscopic properties of plasmonic nanoparticles. He then obtained his Ph.D. with Prof. Chad Mirkin at Northwestern University (Evanston, IL) in 2006. 

During that time, he studied the electrochemical properties of organic adsorbates patterned onto gold films and developed massively parallel scanning probe lithography approaches. From 2006-2009, Khalid was a postdoctoral scholar with Prof. Jay T. Groves at the University of California at Berkeley (USA) where he investigated the role of receptor clustering in modulating cell signaling. In 2009, Khalid started his own lab at Emory University, where he is currently investigating the use of nucleic acids as molecular force sensors, smart drugs, and synthetic motors. 

In recognition of his independent work, Khalid has received a number of awards, most notably: the Alfred P. Sloan Research Fellowship, the Camille-Dreyfus Teacher Scholar award, the National Science Foundation Early CAREER award, the Kavli Fellowship, and Merck Future Insight Prize. Khalid is currently the director of the Center on Probes for Molecular Mechanotechnology, and an Associate Editor of SmartMat. Khalid’s program has been supported by NSF, NIH, and DARPA.

Paul S. Russo is a Professor of Materials Science and Engineering with a joint appointment in the School of Chemistry and Biochemistry at the Georgia Institute of Technology with expertise in polymer, biopolymer and particle chemistry.

His research interests are rooted in rodlike polymers, such as plant viruses, cellulose derivatives and aromatic backbone materials. Particular emphasis has been paid to molecular transport in complex fluids containing rods and to related measurement methods. Static and dynamic laser light scattering have been joined by fluorescence photobleaching recovery and pulsed field gradient NMR spectroscopy to measure diffusion in dilute and concentrated solutions, gels, and liquid crystals. Dialysis implementations of these techniques have permitted stability studies of the amyloid protein responsible for Alzheimer’s disease. Other materials of interest include organophilic polypeptides, which have been coupled to silica cores to yield hybrid particles that can carry hydrophobic payloads, such as enzymes. The same particles can also form colloidal crystals and linear arrays. Small-angle x-ray scattering plays a role in the characterization of these materials. Hydrophobic proteins are being used to template the synthesis of polymers in new and unusual shapes and to disperse oil following marine spills.

 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.
