Dr. Hanjoong Jo is John and Jan Portman Professor in the Coulter Department of Biomedical Engineering (BME) at Georgia Tech and Emory University, and Professor of Medicine at Emory University. He is also the Associate Chair of Emory in BME Department. Upon graduation from Korea University, Dr. Jo received PhD under the co-mentorship of Professors John Tarbell (Chemical Engineering) and Ted Hollis (Physiology) at Pennsylvania State University in 1989. Following postdoctoral training in Jay McDonald Lab at Washington University in St. Louis and University of Alabama at Birmingham, he became Assistant Professor in Pathology and BME. Dr. Jo joined the BME Department at Georgia Tech and Emory University in 2000. He directs the Cardiovascular Mechanobiology and Nanomedicine lab. His lab studies how mechanical force associated with blood flow regulates vascular biology and cardiovascular disease, especially atherosclerosis, aortic valve (AV) calcification, and abdominal aortic aneurysms. He has published more than 150 peer-reviewed papers and edited two books. He developed the mouse model of atherosclerosis, known as partial carotid ligation model, induced by disturbed flow. His work led to the discovery of several genes (mechanosensitive genes and microRNAs) and epigenetic controlling mechanisms that are regulated by bad blood flow and play key roles in atherosclerosis and AAA. By targeting some of these mechanosensitive genes, his lab has been able to treat atherosclerosis and AAA in mice. His lab is now working on nanotechnologies to developing targeted gene and drug therapies in an effort to translate mouse studies toward clinical application. He is an elected fellow of American Institute of Medical and Biological Engineering, Biomedical Engineering Society, American Heart Association and American Physiological Society. He serves as associate editors and editorial board members of several cardiovascular and biomedical engineering journals including Scientific Reports, Circulation Research, Atherosclerosis Thrombosis Vascular Biology, Am J Physiology, Cell Molecular Bioengineering and Cardiovascular Engineering and Technology. He also has been serving as reviewers and chairs of study sections of the NIH, NSF, Veterans Administration and Am Heart Association. He also organized several international meetings, and in 2012, he served as the Chair of the Annual BME Society Meeting. He is also the founding President of Korean-American BME Society and Chairs of US-Korea Annual BMES Workshops since 2013. He has been a Distinguished Visiting Professor at Ewha Womans University and Chonbuk National University.

    The fundamental question we are trying to answer is how the coordinated cell movements are regulated during animal development. Different groups of cells move to different locations in a growing embryo to give rise to specific tissue and structures. It is a very complex process since the "ground" cells travel on is also undergoing constant rearrangement and growth. We use neural crest as a model to study the mechanisms of cell migration during embryonic development. The neural crest is a vertebrate innovation, comprised of highly migratory stem-like cells that give rise to multiple tissue and structures, including craniofacial bones and cartilages, connective tissue in the heart, enteric nervous system in the gut, and pigment cells all over the skin. Defects in their proliferation, migration, differentiation, or survival lead to numerous diseases and birth defects, including craniofacial and heart malformations as well as different types of cancer. Ongoing studies aim to uncover how their migration is regulated and how do they achieve such extraordinary migratory abilities.

    Mass Spectrometry (MS) is one of the key analytical methods used to identify and characterize small quantities of biological molecules embedded in complex matrices. Although MS has found widespread use, improvements are still needed to extend its application to the grand challenges of this century. Since starting my position at Georgia Tech in 2004, my group members and I have used an integrated strategy with roots in bioanalytical chemistry, instrumentation development, bioinformatics, and theoretical modeling to focus on questions of great societal and scientific significance. To this purpose, we have integrated with cross-cutting teams devoted to problems that range from explaining the origins of life on Earth and diagnosing cancer at an early stage, to tracking the sources and prevalence of counterfeit pharmaceuticals worldwide. The common theme along these questions is the need for highly accurate tools for quantifying, identifying, and imaging trace chemicals in complex mixtures. Research in our lab uses state-of-the-art mass spectrometry, ion mobility gas-phase separations,ultrahigh performance liquid chromatography, and new soft ion generation techniques. We investigate the obtained data using machine learning and other powerful bioinformatic approaches. Our group is very dynamic, and each student pursues more than one project at a time, usually in collaboration with other group members or with other research groups at GT or elsewhere. Graduate and undergraduate students are trained in a variety of bioanalytical instrumentation/methodologies, with an emphasis on the fundamentals. We are analytical mass spectrometrists at heart, and strive to answer "big" scientific questions or questions with a large societal impact.

    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 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.

    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.

    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.
