Chenkai Dai

Associate Professor of School of Aerospace & Mechanical Engineering, University of Oklahoma. A key aspect of our research is to develop medical devices/treatments to restore damaged hearing and balancing function caused by various injuries. Our research focuses on measurements hearing/balancing damage by blast or chronic noise and develop hearing protection protocol /devices for personnel exposed to various noises. We also make research efforts combine various interdisciplinary approaches to address the issue of tinnitus and aging hearing and balancing loss. Another research goal is to develop a comprehensive ear computational model to do full analysis including mechanics, electricity and physiology simulation, providing a future virtual model for medical professionals to perform clinical procedures.

Founding Director, Stephenson Chair and Professor of Biomedical Engineering, and Courtesy Professor of Aerospace and Mechanical Engineering, University of Oklahoma. The central theme of my research group is translational regenerative medicine. Techniques employed in my laboratory include 3D printing, microsphere fabrication, electrospinning, colloidal gels, and viral and non-viral gene delivery to mesenchymal stem cells. We leverage these tools to solve problems relating to TMJ disorders, knee cartilage injury, traumatic brain injury, hearing loss, and tracheal stenosis.

Assistant Professor of Anthropology, Co-director at the University of Oklahoma's Laboratories of Molecular Anthropology and Microbiome Research. Dr. Hofman’s research integrates interdisciplinary methods and fields, including genomics, ancient DNA, proteomics, and archaeology to explore human-environment interactions on two very different scales. First, she investigates human-wildlife interactions and their influence on changing environments over the past millennia to inform conservation decisions. Second, Dr. Hofman conducts research on the evolution of the human microbiome, especially with respect to how significant cultural changes (ie agriculture, industrialization, etc.) impact the microbiome. Dr. Hofman is also research associate at the Smithsonian’s National Museum of Natural History.

Professor of Electrical and Computer Engineering. The overall mission of Dr. Jo’s research program is to develop optical sensing and imaging technologies that will impact how we: (1) study pathophysiological mechanisms underlying major human diseases; and (2) clinically manage patients suffering from these conditions. While most academic labs in the field of biomedical imaging focus on either instrumentation development or computational imaging science, Dr. Jo leads a very unique research program dedicated to address major unmet needs in both biomedical research and clinical practice through the design, development, and validation of both optical imaging/sensing instrumentation and computational methods for the nondestructive, non or minimally invasive morphological, molecular and physiological characterization of biological and engineered tissues at multiple spatial and temporal scales. Dr. Jo’s research program is currently being funded by the National Institute of Health (NIH: NCI, NHLBI), the American Heart Association (AHA), the Cancer Prevention and Research Institute of Texas (CPRIT), and the Qatar National Research Fund (QNRF).

Associate Professor of Anthropology, Co-Director of the Laboratories of Molecular Anthropology and Microbiome Research (LMAMR). Dr. Lewis’s research addresses questions concerning the distribution and evolution of human genetic variation – both with respect to the human genome and the human microbiome. To address these questions, he has collected and/or analyzed ancient DNA, genetic data from hypervariable mitochondrial regions, from autosomal functional regions, genome-wide survey of Short Tandem Repeats, and microbial genomes. Research topics include human population history, the evolution of disease associated genetic variation, and the relationship between cultural, environmental and genetic variation.

Our research addresses questions on the structure, function, and evolution, of microbial communities within the context of two distinct ecological niches; the Human microbiome, and Hypersaline environments. We employ a wide range of conventional molecular biology and microbiology techniques, coupled with second generation sequencing and informatics, to address these questions. Current research projects include exploring gut microbial diversity and function among people across distinct lifeways, Algal-Archaeal interactions in hypersaline environments, and long-term preservation of biomolecules in salt cores.

Professor of Electrical and Computer Engineering, Oklahoma TSET Cancer Research Scholar at the Peggy and Charles Stephenson Cancer Center. Dr. Zheng’s research field is developing and validating computer-aided detection and diagnosis (CAD) schemes of medical images. The primary purpose of the research is to develop and provide clinicians more reliable and quantitative medical image and signal data analysis tools that have potential to improve efficacy of cancer screening, diagnosis, and prognosis assessment. Current research interest and activities in his CAD laboratory include (1) developing and evaluating breast cancer risk stratification models for predicting risk of women developing breast cancer in near-term (e.g., <5 years after a negative screening examination), (2) optimizing and testing the interactive CAD systems using content-based image retrieval (CBIR) technology, which provide “visual aid” to radiologists in tumor diagnosis and/or classification, (3) investigating and applying new optical and electrical testing methods to detect properties of tumor tissues or cancer cells, which will be used to generate computerized biomarkers for assessment of cancer prognosis.
