We develop novel statistical techniques for nonparametric Bayes analysis
of high-dimensional covariate data, directly motivated by the largest
population-based study ever conducted on the causes of birth defects.
The methods we develop will enable borrowing of information and
shrinkage across high-dimensional environmental, biomedical,
pharmacological, and sociodemographic risk factors (and interactions
among them) and across a multitude of birth defects, many of which are
too rare to be studied in isolation. Using a hierarchical structure
directly motivated by embryonic development, the borrowing of
information can be informed by our knowledge of mechanistic development
of the embryo. These novel methods may significantly impact the study of
rare congenital malformations. The methods to be developed have broad
application in public health and medicine, where exposures or
characteristics of interest may be great in number and interactions are
important.
At the end of the talk I will briefly present several large,
publicly-available datasets that are products of UNC research for those
who are looking for inspiration for new methodology (or for good
datasets to illustrate innovative methodology) of High-Dimensional
Exposures and Outcomes in an Epidemiologic Study.
