Krishnendu Roy
krish.roy@gatech.edu

 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.

The overall goal of our research endeavor is the development of new biomaterial-based strategies for gene/drug delivery and stem cell engineering. Towards this, my laboratory focuses on three major directions: (a) design and development of novel delivery systems for nucleic-acid based immunotherapy and cancer chemotherapy (b) engineering complex microenvironments to study and manipulate stem cells and understand their behavior in biomimetic, three-dimensional conditions and (c) developing novel engineering tools and high throughput methods to generate functional T cells and Dendritic cells from stem cells.

Metalloproteins constitute one of the largest classes of proteins in the proteome and are involved in virtually every metabolic and signaling pathway of consequence to human health and disease. Broadly speaking, the Reddi laboratory is interested in determining the cellular, molecular, and chemical mechanisms by which metalloproteins are activated by cells, and once activated, how they communicate with other biomolecules to promote normal metabolism and physiology, placing an emphasis on systems relevant to cancer, neurodegenerative disorders, and infectious diseases. Current projects in the lab are focused on elucidating heme trafficking pathways and the role of Cu/Zn Superoxide Dismutase (SOD1) in redox signaling. Prospective students will get broad training in disciplines that span modern biochemistry, bioinorganic chemistry, biophysics, chemical biology, molecular genetics, and cell biology.

William Ratcliff

I am an evolutionary biologist broadly interested in the evolution of complex life. My Ph.D. training focused on the evolutionary stability of cooperation in the legume-rhizorium symbiosis. Here I developed new experimental methods to study how among-organism genetic conflict arises and can be mitigated. A similar evolutionary tension lies at the heart of all key events in the origin of complex life, termed the ‘Major Transitions in Evolution’: namely, how do new organisms arise and evolve to be more complex without succumbing to within-organism conflict? Studying the early evolution of multicellular organisms has been particularly difficult because these transitions occurred deep in the past, and transitional forms have largely lost to extinction. As a postdoc, I circumvented this constraint by creating a new approach to study the evolution of multicellularity: we evolved it de novo. Since founding my own research group at Georgia Tech in 2014, I have combined this approach with mathematical modeling and synthetic biology to examine how simple clumps of cells evolve into multicellular organisms. Our research has shown how classical constraints in the origin of multicellularity — e.g., the origin of life cycles, multicellular development, cellular differentiation, and cellular interdependence — can be solved by Darwinian evolution. At home, I raise two kids on a hobby farm (really just a big garden) with bees, chickens, rabbits, goats, a dog, and lots of edible plants.

Major transitions in evolution (mainly multicellularity). Spatial dynamics of microbial social interactions. Bet hedging. Life cycle evolution. Origin of multicellular development. The transition to multicellularity was critical for the evolution of of large, complex organisms. However, little is known about how early multicellular organisms arise from unicellular ancestors, or how these relatively simple clusters of cells evolve greater complexity. We address both of these issues using experimental evolution, creating new multicellular life in a test tube. Using these model systems (and a good bit of mathematical / computational modeling), my lab explores the origin of multicellular development, cellular division of labor, and mechanisms to prevent cell-level evolution from eroding multicellular complexity. Major transitions in evolution (e.g. multicellularity) are a special case of a more general phenomenon: social evolution. Through collaborations with Brian Hammer (GT Biology), Peter Yunker (GT Physics), and Joshua Weitz (GT Biology), our group examines the spatial dynamics of microbial ecology and evolution.
