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.

My research interests center on control of movement by sensorimotor integration in the mammalian spinal cord. Using predominantly electrophysiological methods applied in vivo, we study neural signaling by spinal motoneurons, somatosensory neurons, and their central synapses. Our primary analyses include electrical properties, synaptic function, and firing behavior of single neurons. We are actively examining how these neurons and synapses respond soon and long after peripheral nerve injury and regeneration. Our recent findings demonstrate that successful regeneration of damaged sensory axons does not prevent complex reorganization of their synaptic connections made within the spinal cord. In separate studies, we are examining novel mechanisms of sensory encoding and their impairment which recently discovered in rodents treated with anti-cancer drugs. Both nerve regeneration and chemotherapy projects are driven by the long-term goal of accurately identifying the neural mechanisms behind movement disorders. We also continue to explore fundamental operations of the normal adult nervous system. Our most recent studies focus on synaptic modulation of motoneuron firing and on interspecies comparisons of spinal circuits.

Yeast genetics and molecular biology, chaperones and protein misfolding, amyloid and prion diseases, epigenetics and protein-based inheritance. Mylaboratory employsyeast models to studyprionsandamyloids.Prionswere initially identified as proteins in an unusual conformation that cause infectiousneurodegenerativediseases, such as "mad cow" disease,kuruorCreutzfeldt-Jakobdisease. Infection depends on theprion'sability to convert anon-prionprotein, encoded by the same host maintenance gene, into theprionconformation.Prionsform ordered cross-beta fibrous aggregates, termed amyloids. A variety of human diseases, includingAlzheimer'sdisease, are associated with amyloids and possess at least someprionproperties. Someamyloidshave positive biological functions. Manyproteins can formamyloidsin specific conditions. It is thought thatamyloidrepresents one of the ancient types of the protein fold. Some yeastnon-Mendelianheritable elements are based on aprionmechanism. This shows that heritable information can be coded in protein structures, in addition to information coded in DNA sequence. Therefore,prionsprovide a basis for the protein-based inheritance in yeast (and possibly in other organisms). Major topics of research in my lab include cellular control of prion formation and propagation (with a specific emphasis on the role of chaperone proteins), and development of the yeast models forstudying mammalian and humanamyloids, involved in diseases.Our research has demonstrated thatprionscan be induced by transient protein overproduction and discovered the crucial role of chaperones inprionpropagation, shown evolutionary conservation ofprion-formingproperties, established a yeast system for studying species-specificity ofpriontransmission,and uncovered links between prions,cytoskeletalnetworks and protein quality control pathways.

Throughout my career, my laboratory has studied sphingolipids, a category of lipids that are important in cell structure, signal transduction and cell-cell communication. For more information about what we found, please refer to the Google Scholar or PubMed links below. 

As an Emeritus Professor, I am working on a project that has interested me for a long time--the fact that the active agent in the venom of the brown recluse spider is a sphingomyelinase D that produces a novel product, ceramide 1,3-cyclic phosphate. This activity has also been found in other spiders, bacteria and fungi. With the help of collaborators, I hope to learn more about the organisms that produce and degrade this novel sphingolipid, and possibly find ways to reduce the injury caused by the enzyme when humans encounter it in the environment.

My laboratory studies a category of lipids, termed sphingolipids, that are important in cell structure, cell-cell communication and signal transduction. This research concerns both complex sphingolipids (sphingomyelins and glycosphingolipids) and the lipid backbones (ceramide, sphingosine, sphingosine 1-phosphate and others) that regulate diverse cell behaviors, including growth, differentiation, autophagy and programmed cell death. The major tool that we use to identify and quantify these compounds is tandem mass spectrometry, which we employ in combination with liquid chromatography for "lipidomic" analysis and in other mass spectrometry platforms (e.g., MALDI) for "tissue imaging" mass spectrometry. To assist interpretation of the mass spectrometry results, and to predict where interesting changes in sphingolipid metabolism might occur, we use tools for visualization of gene expression data in a pathway context (e.g., a "SphingoMAP"). These methods are used to characterize how sphingolipids are made, act, and turned over under both normal conditions and diseases where sphingolipids are involved, such as cancer, and where disruption of these pathways can cause disease, as occurs upon consumption of fumonisins. Since sphingolipids are also components of food, we determine how dietary sphingolipids are digested and taken up, and become part of the body's "sphingolipidome."

Additional Research
A central challenge for many organisms is the generation of stable, versatile locomotion through irregular, complex environments. Animals have evolved to negotiate almost every environment on this planet. To do this, animals'nervous systems acquire, process and act upon information. Yet their brains must operate through the mechanics of the body's sensors and actuators to both perceive and act upon the environment. Ourresearch investigates howphysics and physiologyenable locomoting animals to achieve the remarkable stability and maneuverability we see in biological systems. Conceptually, this demands combining neuroscience, muscle physiology, and biomechanics with an eye towards revealing mechanism and principle -- an integrative science of biological movement. This emerging field, termedneuromechanics, does for biology what mechatronics, the integration of electrical and mechanical system design, has done for engineering. Namely, it provides a mechanistic context for the electrical (neuro-) and physical (mechanical) determinants of movement in organisms. Weexplore how animals fly and run stably even in the face of repeated perturbations, how the multifuncationality of muscles arises from their physiological properties, and how the tiny brains of insects organize and execute movement.
