Bioinformatics Investigators

  • Cho, HyungJun, PhD  Dr. Cho has worked on statistical research in medical and biological data. He has applied and developed many computational and statistical techniques for various problems in biological and medical studies. Dr. Cho's current interest is in statistical and computational analysis of high-throughput  genomic and proteomic data.
  • French, Brent A., PhD. Dr. French's laboratory works at the interface between molecular biology, cardiovascular science and biomedical engineering. An interdisciplinary approach is used to integrate recent technical advances in bioengineering with basic research in the area of ischemic heart disease. Specifically, this research employs cutting-edge imaging techniques such as cardiac MRI to provide accurate assessments of the efficacy of novel therapeutic approaches against myocardial infarction and heart failure. Current research projects in the laboratory also use molecular techniques to characterize the role of inflammation in myocardial infarction and heart failure. Recent work shows that the biological messenger nitric oxide plays a multifunctional role in protecting the heart against ischemic damage. Thus one project seeks to elucidate the diverse functions of nitric oxide during and after ischemia / reperfusion injury to the heart. For example, molecular techniques are now being used to correlate changes in NOS gene expression with in vivo functional changes in the heart as measured by cardiac MRI.
  • Johnson, Michael., PhD. Dr. Johnson has a Ph.D. in biophysics with a specialty in modeling of biological processes. Dr. Johnson has authored more than 208 publications and edited 8 books, the majority of which involve mathematical modeling of biological processes (particularly numerical computer methods and quantitative neuroendocrinology).
  • Knaus, William A., MD. Secure Digital Record Repository for Virginia (SDRRV)- SDRRV's objective is to create a secure record repository utility across the state that will combine biologic, clinical, demographic, environmental, and outcomes data. SDRRV will address the fundamental scientific questions of how multi-dimensional and multi-source data can be integrated in a manner that engenders the trust of Virginia's citizens with respect to protection of individual biologic and related personal and social information. The SDRRV will also be designed to enable institutions across the state to efficiently meet the new HIPAA (Health Insurance Portability and Accountability Act) requirements while broadening their abilities to use and integrate data for a variety of scientific research and public policy purposes with primary attention to ethical principles and civil rights. The SDRRV will use a computer science/systems engineering approach to design integration, optimize functionality, and create efficient human-computer interfaces. SDDRV will initially identify the types and sources of new biologic and genetic data and the variety of existing and proposed methods and tools designed for their interpretation. A detailed examination of the logistic, technical, legal, scientific, and political challenges encountered in collecting, storing, interpreting, and integrating these data with existing electronic sources of clinical, demographic, environmental, public health, and outcomes information will be completed. Then, in an open-architecture, academic, industry, government, and citizen-endorsed effort, SDRRV will implement a working prototype and pilot of a digital record based repository. The prototype will involve a minimum of seven major research-based Virginia Universities, the state's Department of Health, the state Legislature and Governor's Office, three integrated health systems, a local community-oriented partnership association, citizen based privacy protection and health care advocacy groups along with representatives from related information and biotechnology based industries. This prototype will encompass a minimum of 50 % of Virginia's population. Data integration will be accomplished by creating a computed grid distributed network among primary information sources linked to specific data-intensive computing applications, methods, and tools in a open source community.
  • Kovatchev, Boris P., PhD. Dr. Kovatchev has 10 years experience in biomathematics. He has had continuous NIH funding since 1996 exclusively dedicated to biomathematical modeling for diabetes research. He has developed the low blood glucose index, the best predictor to date of severe hypoglycemia, created the theory of risk analysis of blood glucose data, developed new computational tools for assessment of behavioral irregularity associated with type 1 diabetes and for assessment of long-term diabetes control, and successfully developed a remarkably accurate deterministic model of insulin-glucose dynamics. Two patent disclosures have been filed and licensed by industry leaders in the area of diabetes management.
  • Lee, Jae K., PhD. Dr. Lee has worked on statistical research in genetic population inference, DNA structure analysis, high-throughput gene chip data analysis, and linkage association study for human genetic diseases. He has applied and developed many computational & statistical techniques for various problems in molecular biology and cancer genetics, such as anticancer gene-drug discovery on high throughput gene expression data and linkage association study for identifying quantitative trait loci of pedigree data. Dr. Lee's current interest is in the analysis and genome-wide information integration of microarray gene expression data. (Dr. Lee's Departmental Web page)

  • Lyman, Jason A., M.D., M.S. Dr. Lyman's research interests include physician order entry, data warehousing, informatics education, data modeling, clinical terminologies, and the application of standards in clinical informatics. In addition to other projects, he has been heavily involved in the collaborative efforts between UVa's HES and Systems Engineering departments to explore the potential for multi-institutional approaches to the integration of clinical, biological, and demographic data.
  • Pearson, William., PhD. Sequences (mostly protein, some DNA) -Sequence/structure relations -Distant homology -Distribution in protein space (is folding easy or hard) -Genome sequences Evolutionary constraints -Functional Predictions from rate analysis -Comparative genomics-are conserved non-coding sequences functional? Genome-Scale data and genome databases -How to integrate quantitative sequences/evolutionary information with qualitative functional information -Displaying information on a genome scale.
  • Peddada, Shayamal D., PhD. Working on several different problems. An example of my research is to develop methods for analyzing time-course and dose-response microarray experiments. I am developing order-restricted inference based procedures for analyzing such data.
  • Pelletier, Sandra., PhD. I received my PhD in biochemistry studying the relationship between protein structure and function in G-protein coupled receptors and did my and postdoctoral training in cell biology researching the entry of influenza virus into host cells. My current position as Assistant Professor of Research in the Department of Health Evaluation Sciences allows me to apply these basic research foundations to clinical care, thus contributing to the bridging of basic and clinical research. My interests include database design, data integration, knowledge representation / ontology and the conceptual development of analyses and methods that utilize clinical data, existing knowledge resources and informatics to further discovery research, clinical diagnostics and the targeting of therapeutics. Knowledge resources of interest include both genomic and proteomic databases. But, I am particularly interested in using knowledge resources related to protein structure, function and interactions (e.g. signal transduction pathways) and those from model organisms to understand complex multifactorial conditions such as cancer and diabetes. Current projects include the integration of patient specific `biological' data (genetic (mutations, gene expression), proteomic profiling) and family health history data into the electronic patient record and the development of methods for analyses that utilize these resources. I also direct my attention to teaching efforts here in the department that address the utilization of genomic, proteomic and knowledge resources as well as science and health education for consumers (e.g. individuals health risks and health practices, middle school kids).
  • Skalak, Thomas C., PhD. We are very interested in a future hire of a faculty member in the area of computational biology-probably-integrative modeling of gene protein circuitry or tissue assembly/remodeling/functionality. We would probably not overlap BME hire in the existing areas of gene sequence homology searching or annotation. My own lab is working on computational automata for predicative modeling of vascular assembly and patterning in mammals, and also applications to developmental processes during early mophogenesis in xenopus.
