Research Abstract
My research involves computational methods to analyze, integrate, and interpret the various sources of biological data for the study of medical, marine, and environmental applications of genomics. I have been involved in a wide range of projects using next generation sequencing, de novo assembly, read mapping, functional annotation, common/rare variants, differential gene expression, and methylation. These bioinformatics analyses have been applied to many human diseases, including addiction, alcohol-induced liver diseases, obesity, longevity, and cancer.
Short Biography
Trina Norden-Krichmar is an Associate Professor in the Department of Epidemiology at the University of California, Irvine. The goal of her research is to investigate the genomic factors influencing human health and disease. She has a B.S. in Biochemistry from University of Maryland, M.S. in Computer Science from George Washington University, and a Ph.D. in Marine Biology from the Scripps Institution of Oceanography at the University of California, San Diego. In addition to the laboratory skills acquired by her biological research, she also has over 15 years of experience working as a computer programmer at IBM, the National Institutes of Health, and the Salk Institute. She has experience performing bioinformatics analyses applied to projects involving RNA sequencing and gene expression microarrays, DNA sequencing and genotyping arrays, microRNAs, methylomics, proteomics, metagenomics, and metatranscriptomics. She teaches a Bioinformatics course at UC Irvine at both the graduate (EPIDEM 275) and undergraduate (PUBHLTH 119) levels.
