    Intercalation-mediated Nucleic Acid Assembly, The Molecular Midwife & the Origin of Life, Nucleic Acid-Cation Interactions, Understanding DNA & RNA Condensation. The research in our laboratory is directed towards elucidating the fundamental chemical and physical principles that govern nucleic acid (RNA and DNA) assembly. We are interested in how the physical properties of nucleic acids govern biological functions in contemporary life, and how these same properties provide clues to the origin and early evolution of life. We are also applying our knowledge of nucleic acids to problems that are of current importance in medicine and biotechnology. Specific projects include investigations of: 1) the origin and evolution of RNA; 2) cation, solvent and small molecule interactions with nucleic acids; 3) nucleic acid condensation and packaging; and 4) folding and evolution of the ribosome. Our research involves the application of a wide variety of physical and chemical techniques.

    The effortlessness of moving your body belies the lurking complexity driving it. We are trying to understand how the nervous system makes something so complicated as controlling a human body feel so natural. We use human subjects studies, animal experiments, mathematical biology, and artificial intelligence to understand neural control of movement. New theories and insight promise advances in physical therapy, human-machine collaboration, brain-computer interfaces, neural modulation of peripheral reflexes, and more.

    The Shoichiro's lab primary research interest is the mechanisms that regulate dynamic rearrangement of the actin cytoskeleton during various cellular events including development, cell movement, cytokinesis, and human diseases. We have been studying this problem using the nematode Caenorhabditis elegans as a model system. C. elegans has been used to study many aspects of development, because of its relative simplicity in the body patterning, and application of genetics, molecular biology, biochemistry, and cell biology. We are especially interested in the functions of the actin depolymerizing factor (ADF)/cofilin family of actin-binding proteins, which are required for enhancement of actin filament dynamics. We found that two ADF/cofilin proteins that are generated from the unc-60 gene have different actin-regulating activities. Mutation and expression analyses demonstrated that one of the two ADF/cofilin isoforms (UNC-60B) was specifically required for organized assembly of actin filaments in muscle. ADF/cofilin promotes depolymerization and severing of actin filaments, but tropomyosin inhibits this effect by stabilizing filaments. The other ADF/cofilin isoform (UNC-60A) is highly expressed in early embryos and regulates cytokinesis and embryonic patterning. In addition, we found that actin-interacting protein 1 (AIP1) is a new regulator of muscle actin filaments. AIP1 (UNC-78) specifically interacts with ADF/cofilin-bound actin filaments and enhances filament depolymerization. We also found that the gene product of sup-12 (an RBM24 homolog) regulates alternative splicing of the unc-60 gene and is required for generation of the unc-60B mRNA. We are currently studying functions of these proteins and other regulators of actin dynamics in several developmental aspects in C. elegans.

    James Dahlman

    Associate Professor

    James Dahlman is a bioengineer / molecular engineer whose work lies at the interface of chemistry, nanotechnology, genomics, and gene editing. His lab focuses on targeted drug delivery, in vivo gene editing, Cas9 therapies, siRNA therapies, and developing new technologies to improve biomaterial design. 

    The DahlmanLab is known for applying 'big data' technologies to nanomedicine. The lab is pioneering DNA barcoded nanoparticles; using DNA barcodes, >200 nanoparticles can be analyzed simultaneously in vivo. These nanoparticles are studied directly in vivo, and used to deliver targeted therapies like siRNA, mRNA, or Cas9. As a result of this work, James was named 1 of the 35 most innovative people under the age of 35 by MIT Technnology Review in 2018. James has won many national / international awards, and has published in Science, Nature Nanotechnology, Nature Biotechnology, Nature Cell Biology, Cell, Science Translational Medicine, PNAS, JACS, ACS Nano, Nano Letters, and other journals. James has also designed nanoparticles that efficiently deliver RNAs to the lung and heart. These nanoparticles can deliver 5 siRNAs at once in vivo, and are under consideration for clinical development. As a result, the lab has an interest in immunology and vascular biology. 

    James supports entirely new research students come up with independently. To this end, DahlmanLab students learn how to (i) generate new ideas, (ii) select the good ones, and (iii) efficiently test whether the good ideas will actually work. 

    Dahlman Lab students learn how to design/characterize/administer nanoparticles, how to isolate different cell types in vivo, how to rationally design DNA to record information, Cas9 therapies, and deep sequencing. As a result, the lab is an interdisciplinary group with students that have backgrounds in medicinal chemistry, BME, bioinformatics, biochemistry, and other fields. The lab welcomes students with all types of scientific backgrounds. The lab firmly stands by students, independent of their personal beliefs, preferences, or backgrounds.

    Additional Research:
    In the Dahlman Lab, we focus on the interface between nanotechology, molecular biology, and genomics. We design drug delivery vehicles that target RNA and other nucleic acids to cells in the body. We have delivered RNAs to endothelial cells, and have treated heart disease, cancer, inflammation, pulmonary hypertension, emphysema, and even vein graft disease. Because we can deliver RNAs to blood vessels at low doses, sometimes we decide to deliver multiple therapeutic RNAs to the same cell at once. These 'multigene therapies' have been used to treat heart disease and cancer. Why is this important? Most diseases are caused by combinations of genes, not a single gene. We also rationally design the nucleic acids we want to deliver. For example, we re-engineered the Cas9 sgRNA to turn on genes, instead of turning them off. This enabled us to easily turn on gene A and turn off gene B in the same cell.

    Additional Research:
    Human health has been transformed by our collective capacity to engineer immunity — from the pivotal development of the smallpox vaccine to the curative potential of recent cancer immunotherapies. These examples motivate our research program that is conducted at the interface of Engineering and Immunology, and where we develop biomedical technologies and applications that shape a diverse array of immunological systems.The questions that are central to our exploration include: How do we begin to study an individual's repertoire of well over one billion immune cells when current technologies only allow us to study a handful of cells at a time? What are the biomarkers of immunological health as the body responds to disease and ageing, and how may these indicators trigger clinical decisions? And how can we genetically rewire immune cells to provide them with entirely new functions to better fight complex diseases such as cancer?To aid in our studies, we use high-throughput technologies such as next-generation sequencing and quantitative mass spectrometry, and pioneer the development of micro- and nanotechnologies in order to achieve our goals. We focus on clinical problems in cancer, infectious diseases and autoimmunity, and ultimately strive to translate key findings into therapies for patients.

    Additional Research:
    LaPlaca's broad research interests are in neurotrauma, injury biomechanics, and neuroengineering as they relate to traumatic brain injury (TBI). The goals are to better understand acute injury mechanisms in order to develop strategies for neuroprotection, neural repair, and more sensitive diagnostics. More specifically, the lab studies mechanotransduction mechanisms, cellular tolerances to traumatic loading, and plasma membrane damage, including mechanoporation and inflammatory- & free radical-induced damage. We are coupling these mechanistic-based studies with –omics discovery in order to identify new biomarker candidates. In addition, LaPlaca and colleagues have developed and patented an abbreviated, objective clinical neuropsychological tool (Display Enhanced Testing for Cognitive Impairment and Traumatic Brain Injury, DETECT) to assess cognitive impairment associated with concussion and mild cognitive impairment. An immersive environment, coupled with an objective scoring algorithm, make this tool attractive for sideline assessment of concussion in athletic settings. Through working on both basic and clinical levels she is applying systems engineering approaches to elucidate the complexity of TBI and promoting bidirectional lab-to-clinical translation.

    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.

    Associate Professor

    Anant Paravastu holds bachelors (MIT, 1998) and Ph.D. degrees (UC Berkeley, 2004) in chemical engineering. His Ph.D. research with Jeffrey Reimer focused on the use of lasers to control nuclear spin polarizations in the semiconductor GaAs. From 2004 to 2007, he worked as a postdoc at the Laboratory of Chemical Physics at NIH with Robert Tycko, where he learned to apply nuclear magnetic resonance to structural biology. Paravastu’s early structural biology work focused amyloid fibrils of the Alzheimer’s β-amyloid peptide. He was part of the team and community that showed that amyloid fibril formation is a complex phenomenon, with individual peptides exhibiting multiple aggregation pathways capable of producing multiple distinct aggregated structures. Between 2008 and 2015, Paravastu worked as an assistant professor at Florida State University and the National High Magnetic Field Laboratory. Paravastu started his present position at Georgia Tech in 2015. Paravastu’s laboratory presently focuses on 3 general lines of inquiry: 1) structural analysis of peptides that were rationally designed to assemble into nanostructured materials, 2) nonfibrillar aggregates of the Alzheimer’s β-amyloid peptide, and 3) aggregation due to misfolding of proteins driven away from their natural folds.
