The Department of Biomedical Data Science invites you to attend a seminar in person on Thursday, July 9 from 12:00-1:00pm at DHMC, Auditorium H with with Eugene Demidenko, PhD, Professor of Biomedical Data Science, Geisel School of Medicine. Visualization of large genomic datasets is of paramount importance for formulating scientific hypotheses before deploying complex data science algorithms to uncover hidden structures, such as clusters or nonlinearities. Novel visualization techniques for big data are demonstrated by the distribution of single-nucleotide polymorphisms (SNPs) in genome-wide association studies (GWAS). To ‘see’ the data in four- or five-dimensional space, we apply slicing to the 3D contour manifold of a kernel density in an interactive setting or automatic animation. Novel methods for correlation-preserving projection of multidimensional genomic data and the gene connection network onto a 2D or 3D sphere are presented. An interactive gene hub visualization of the Gene Planet will be developed, allowing users to zoom in or out to view gene connections at varying levels of detail, similar to popular online software such as Google Maps or Google Earth. Finally, we discuss how sound can be integrated with our visualization algorithms to sonify the unseen data features. The ultimate goal is to equip genetic researchers with next-generation exploratory data research tools that incorporate novel interactive graphics and data sonification to address the complexity of genetic data through controlled data-science video gaming.
