Melissa Kemp

Melissa Kemp's profile picture
melissa.kemp@bme.gatech.edu

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.

Additional Research
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.

Additional Research
The goal of my research is to develop a method for mapping spontaneous activity throughout the whole brain with high spatial and temporal resolution, with the intention of using this technique to characterize alterations in dynamic neural activity linked to dysfunction and to identify potential targets for intervention. My primary expertise is in fMRI and functional connectivity mapping, and since my lab was established at Emory, we have focused on obtaining information about the dynamic activity of functional networks from the BOLD signal. Despite BOLD's indirect relationship to neural signals, evidence is growing that the BOLD fluctuations provide information about behaviorally relevant network activity. We take a two-pronged approach to the problem, combining MRI with direct neural measures like electrophysiology and optical imaging in the rodent, or with EEG and behavioral outputs in the human. Our effort to understand the relationship between BOLD and electrical or optical recordings (very different signals that cover very different spatial and temporal scales) has led us to develop new approaches to data analysis that include spectral, spatial, and temporal information. To better understand the large-scale dynamics of brain activity, we have become fluent in network modeling, nonlinear dynamics, and machine learning.

Karmella Haynes

Many people are familiar with “genetics,” the inheritance of visible traits like eye and hair color. Traits are encoded by a molecular alphabet (A,T,C,G) in the well known double helix structure, DNA. Less well known, but quickly gaining attention, is the network of protein particles that interact with DNA to control the folding of chromosomes and the expression of inherited traits. This process is epi-genetics (epi, EH-pee = upon or above). Our research group uses gene and protein engineering to create new epigenetic machinery that regulates DNA at will. One day synthetic epigenetics may allow us to rationally design new biological systems with predictable, reliable behavior and replace “magic bullet medicine” with “smart medicine.”

We assemble interchangeable protein modules to build synthetic transcription factors that regulate gene activity in human cells. Unlike typical synthetic transcription factors that recognize specific DNA sequences, our Polycomb-based transcription factors (“PcTFs”) are engineered to read chromatin modifications. Thus, a single engineered TF could activate a group of silenced, therapeutic genes in cancer cells. Using strong gene activators could enhance cancer treatment and advance epigenetic medicine.

As synthetic biologists, our goal is to make the folded DNA-protein material, or chromatin (KRO-mah-tin = dark colored material in the nucleus of a fixed and stained cell), easier to design and engineer. Groups of genes often reside in the same compartments, and share the same DNA-protein packaging structures. Therefore, a small artificial change in one packaging protein can reprogram the expression of dozens, and even hundreds of genes. Is this outcome messy and useless, or is it a powerful mode of signal amplification that changes cells in useful ways? To answer this question, our group couples synthetic biology with bioinformatics by interrogating the expression of thousands of genes after we introduce artificial chromatin proteins into cells.

"Biomechanics and mechanobiology, glaucoma, osteoarthritis, regenerative medicine, intraocular pressure control, optic nerve head biomechanics. We work at the boundaries between mechanics, cell biology and physiology to better understand the role of mechanics in disease, to repair diseased tissues, and to prevent mechanically-triggered damage to tissues and organs. Glaucoma is the second most common cause of blindness. We carry out a range of studies to understand and treat this disease. For example, we are developing a new, mechanically-based, strategy to protect fragile neural cells that, if successful, will prevent blindness. We are developing protocols for stem-cell based control of intraocular pressure. We study the mechanobiology and biomechanics of neurons and glial cells in the optic nerve head. We also study VIIP, a major ocular health concern in astronauts. Osteoarthritis is the most common cause of joint pain. We are developing paradigms based on magneto-mechanical stimulation to promote the differentiation and (appropriate) proliferation of mesenchymal stem cells."
