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.

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 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.

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.
