Melissa Lambeth Kemp received her B.S. in Nuclear Engineering from MIT and her Ph.D. in Bioengineering from University of Washington. Dr. Kemp joined the faculty at Georgia Tech in 2006 after completing postdoctoral training at MIT. Her expertise is in computational modeling of metabolism and signal transduction, as well as developing statistical modeling tools to examine network relationships in high-dimension datasets. One major aspect of her research program linking ROS – the byproducts of aerobic metabolism – to the fundamental way that cells interpret instructions from their environment, their neighbors, and their own genetic blueprint. Specific applications of her diverse work include systems modeling of transient phosphatase oxidation of kinase cascades, patient-specific differences in cytotoxicity to redox-cycled chemotherapeutics and radiation, and the coordination of oxidative metabolism with epithelial-to-mesenchymal transition. Her research program also includes a component of developing high-throughput screening methods for assaying cue-signal-response relationships in cells and analytical tools for single cell gene expression. 

Dr. Kemp currently serves as the Research Director of the multi-site NSF Engineering Research Center “Cell Manufacturing Technologies”. In her former role as Associate Director of the NSF Science and Technology Center “Emergent Behavior of Integrated Cellular Systems”, she spearheaded the multi-site center’s computational activities by developing agent-based models of context-dependent cellular decisions to generate new hypotheses of intercellular communication in pluripotent stem cell differentiation and emergent patterning; this work continues currently in quantifying organizational principles and spatial relationships in iPSC-derived tissues from multi-omics data. Dr. Kemp’s career honors include a Whitaker Graduate Fellowship, Merck/CSBi postdoctoral fellowship, Georgia Cancer Coalition Distinguished Scholar, NIH New Innovator Award, and the CSB2 Prize for Innovative Measurement Methods from the Council for Systems Biology in Boston.

Systems biology, computational modeling, redox metabolism and signal tranduction.The Kemp Lab is focused on understanding how metabolism influences the decisions that cells make. Aging, stem cell differentiation, cancer metastasis, and inflammation rely on progressive changes in metabolism resulting in increased levels of reactive oxygen species. Collectively, the accumulation of these molecules is known as cellular oxidation, and pathological levels are referred to as oxidative stress. Our lab develops systems biology tools for investigating how cellular oxidation influences cellular fate and interpretation of cues from the extracellular environment. We are interested in the collective behavior that arises during stem cell differentiation, immune cell responses, or drug treatments from metabolic diversity in individual cells. Because of the numerous biochemical reactions involved, we develop computational models and analytical approaches to understand how complex protein network properties are influenced by redox-sensitive proteins; these proteins typically have reactive thiol groups that are post-translationally regulated in the presence of reactive oxygen species to alter activity and/or function. Experimentally, we develop novel high-throughput single cell techniques for the detection and quantification of intracellular oxidation.

Dr. Kostas Konstantinidis joined the Georgia Institute of Technology as an Assistant Professor in November 2007. He received his BS in Agriculture Sciences from the Aristotle University of Thessaloniki (Greece) in 1999. He continued his studies at the Center for Microbial Ecology at Michigan State University (East Lansing, MI) under the supervision of Prof. James M. Tiedje, where he obtained a PhD in 2004. His PhD studies were fully supported by the Bouyoukos Fellowship program and were devoted in advancing our understanding of the ecology and physiology of soil bacteria through the comparative analysis of their whole-genome sequences. This research resulted in a NSF-funded project to advance the species definition for prokaryotes, which also fostered a short post-doc position at the Center for Microbial Ecology. He then moved to MIT and the laboratory of Prof. Edward DeLong to get trained on innovating metagenomic techniques. His work at MIT provided important new insights into the complexity and function of oceanic microbial communities as well as how life is adapting in the deep and cold Oceans. His research interests are at the interface of genomics and computational biology in the context of microbial ecology with the overarching goal to broaden understanding of the genetic and metabolic potential of the microbial world. Advancing our knowledge on these issues is essential for a better understanding of the microbes that power, by and large, the biogeochemical cycles that sustain life on Earth and cause or control important diseases in humans and animals. He is a member of the American Society for Microbiology (ASM), the International Society for Microbial Ecology (ISME) and the Association of Environmental Engineering and Science Professors (AEESP). Konstantinidis held the Carlton S. Wilder Junior Professorship for five years and subsequently received the Maulding Faculty Fellowship in the School of Civil and Environmental Engineering.

Metals In Biological Systems. Approximately one third of all known proteins contain metal ions as cofactors and serve a wide variety of functions, such as structure stabilization, catalysis, electron transfer reactions or complex tasks, including signal transduction and gene regulation. Numerous diseases such as haemochromatosis or Menkes disease were found to be related with a defect in metal metabolism. Research is concerned with development of metal specific fluorescent probes for the investigation of the intracellular chemistry of trace elements, the mechanistic study of metalloprotein catalyzed reactions with unusual coordination geometries as well as the development of protein-based, semisynthetic organometallic catalysts in aqueous solution. Fluorescence Probes and Chelators for the Investigation of Intracellular Storage, Trafficking, and Homeostasis of Trace Elements. Until recently, little was known about how eukaryotic cells take up metal ions or regulate intracellular concentrations. Fluorescent chemosensors have been proven to be powerful and nondestructive tools for the study of intracellular metal ion distributions and have provided a wealth of information, including control of muscle contraction, nerve cell communication, hormone secretion, and immune cell activation. Research is concerned with the development of highly specific fluorescent probes for the detailed mechanistic investigation of copper storage and trafficking. Distribution and changes of intracellular copper concentration can be followed in vivo using fluorescence microscopy. Various combinatorial fluorophore libraries are being synthesized, which subsequently are screened for copper binding selectivity. Bioorganometallic Catalysis with Peptide and Protein Ligands. The distribution of metal ions in sea water can be directly correlated with their abundance in biological systems. Consequently, the platinum metals palladium, rhodium, iridium and platinum are not found in any of the natural occurring metalloproteins. Nevertheless, these cations are excellent catalysts for a wide variety of organometallic reactions. Research is focused on combining the rich chemistry of platinum metals with the advantage of proteins to catalyze reactions with high regio- and stereo-selectivity. Novel bioorganometallic catalysts are being developed via redesign of structurally well characterized proteins.

Research in the Wu lab is mainly focused on mass spectrometry (MS)-based proteomics. They are developing innovative methods to globally identify and quantify proteins and their post-translational modifications (PTMs), including glycosylation and phosphorylation, and applying them for biomedical research. Protein PTMs plays essential roles in biological systems, and aberrant protein expression and modification are directly related to various human diseases, including cystic fibrosis, cancer and infectious diseases. Novel analytical methods will profoundly advance our understanding of protein function, which will lead to the identification of proteins or modified proteins as effective drug targets and the discovery of biomarkers for early disease detection.

Engineering of genetically encoded biosensors Quantitative fluorescence microscopy and image analysis Computational models of gene regulatory networks Transcriptional regulation and developmental biology of plants The past fifteen years has seen dramatic advancements in genome sequencing and editing. The cost of sequencing a genome has decreased by two orders of magnitude, giving rise to new systems-level approaches to biology research that aim to understand life as an emerging property of all the molecular interactions in an organism. At the same time, technologies that allow site-specific modifications of the genome are enabling researchers to manipulate multicellular organisms in unprecedented ways. From reductionist approaches to systems biology, and from conventional plant breeding to synthetic biology, the future of plant biology research relies on the adoption of computational methods to analyze experimental data and develop predictive models. In biomedicine, mathematical models are already revolutionizing drug discovery; in agriculture, they have the potential to generate more efficient, faster growing crop varieties. The goal of the Cheung lab is to bring quantitative techniques and mathematical modeling to plants in order to gain systems-level insight into their physiology and development - particularly to understanding how metabolic and gene regulatory networks interact to control homeostasis and growth.
