  • Bayes Regularization and Microbiome Multi-Omics: A Two-Tailed Narrative - Dr. Mallick

    Biostatistics Branch Seminar Series

    In this talk, I will present a statistical narrative of two seemingly different but equally exciting topics: Bayes regularization and microbiome multi-omics, drawing upon my PhD and postdoc experience of researching in two vastly different academic settings.

  • Novel Epidemiological Risk Models, with Application to Screening - Dr. Cheung

    Biostatistics Branch Seminar Series

    My research interest focuses on the development of statistical methods for analyzing electronic health record data, using these methods to model the natural history of intervening stages in the carcinogenic process, and the development of evidence-based cancer screening guidelines. I will discuss some of the critical statistical challenges involved in analyzing such data, and why standard tools for absolute and relative risk estimation are biased. I will introduce new statistical models that can be used to produce unbiased estimates in cohort studies with multiple time point data and biospecimen collection. These models are used to develop new risk-based management guidelines for cervical cancer. I will also discuss risk models and benefit models for oral cancer and lung cancer screening.

  • Virtual Pooled Registry- Dr. Danping Liu, Part 2 of 3

    Biostatistics at the Frontier Seminar Series

    This seminar is a part 2 of 3 of the 2020 Biostatistics at the Frontier Seminar Series

  • Feature Selection with Survival Outcome Data - Dr. Hong

    Biostatistics Branch Seminar Series

    Detecting biomarkers that are relevant to patients' survival outcome is crucial for precision medicine. Dimension reduction is key in the process. Although regularization methods have been used for dimension reduction, they cannot handle a large number of candidate biomarkers generated by modern bio-techniques. Variable screening, which has been widely used for handling exceedingly large numbers of variables, is however much underdeveloped for censored outcome data.

  • Methods for Population Health with Limited Data - Dr. Li

    Biostatistics Branch Seminar Series

    Data describing health outcomes of hidden populations and in low-resource areas are usually noisy and incomplete. In this talk, I will discuss two projects in such data-constrained settings.

    March 31, 2020 | 10:30 AM – 11:30 AM

  • NIH Human Subjects Research Protections Program – Updates for DCEG Studies - Drs. Savage and McMaster

    DCEG Seminar

    Drs. Savage and McMaster will provide an update on the central NIH IRB, Non Human Subject Research (NHSR), and NCI Ethical Review Panel review processes for DCEG studies. All are highly encouraged to attend to receive clarifications on these processes.

    March 25, 2020 | 11:00 AM – 12:00 PM

  • Estimating Somatic Variant Richness & Using the “Hidden” Genome to Improve Classification of Cancer Types - Dr. Chakraboty

    Biostatistics Branch Seminar Series

    It is increasingly common clinically for cancer specimens to be examined using techniques that identify somatic mutations. In principle these mutational profiles can be used to diagnose the tissue of origin, a critical task for the 3-5% of tumors that have an unknown primary site. Diagnosis of primary site is also critical for screening tests that employ circulating DNA.

  • Methods for Clinical Decision-Making: Risk Models with Polygenic Risk Scores - Dr. Meisner

    Biostatistics Branch Seminar Series

    This research lies in the development of statistical methods that can be used to inform clinical decision making. These methods aim to provide actionable, relevant information to patients and clinicians such as risk of a particular disease or response to a given treatment. In this seminar, Dr. Meisner will outline the broad themes of her research, discuss in detail two recent projects related to polygenic risk scores (PRS), and touch on possibilities for future work, including methods for PRS as treatment selection tools.

  • Various Usage of Influence Functions for Complicated Statistics in the Context of Survey Sampling - Dr. Yu

    Biostatistics Branch Seminar Series

    Seminar: Publicly available national survey data are useful for the evidence-based research to advance our understanding of important questions in the health and biomedical sciences. Dr. Yu discusses methods of appropriate variance estimation.

  • From Genome-Wide Association Studies to Biological Insights Using Integrative Molecular Epidemiology - Dr. Kraft

    DCEG Seminar

    Genome-wide association studies (GWAS) have identified thousands of common genetic variants robustly associated with risk of cancer, yet the biological mechanisms underlying these associations remain largely unknown, in part because of confounding by local correlation among variants, and in part because most of these variants are located in non-coding regions with poorly-understood functionality. Methods that integrate GWAS results with auxiliary data can suggest biological hypotheses for further in silico, in vitro and in vivo studies.
