Langefeld is a biostatistician whose research focuses on mapping complex
genetic traits. He has two broad areas of research: 1) identification of
genomic variation that predisposes to traits related to cancer, renal disease,
diabetes, obesity, heart disease, stroke, and autoimmunity, and 2) development
of analytic and bioinformatic methods to assist in the identification and
interpretation of this variation. He plays leadership roles in several
international genetics consortia and has served on numerous NIH (former standing
member of CASE) and foundational grant review panels. As Director of the
Center for Public Health Genomics at Wake Forest and the Associate Director of Statistical
Genomics and Bioinformatics within the Biostatistics and Bioinformatics Shared
Resource, he is very interested in developing genomics, pharmacogenomics and
precision medicine relative to cancer. In
collaboration with, David McWilliams Ph.D., Jeff Chou, Ph.D. and he has
developed DNA-seq and RNA-seq analysis pipelines, including an ION
Torrent-based DNA-seq analysis pipeline to inform childhood cancer treatment
strategies (Patrick Koty, Ph.D.). He is currently working with Drs. Glenn
Lesser and Douglas Case of the Comprehensive Cancer Center to complete a
genome-wide association study on radiation toxicity for breast cancer.
