Research Focus
Dr. Mahaney has a broad educational background in genetics, human physiological and anatomical variation, and comparative primate biology and evolution, as well as over 30 years of post-graduate research experience in quantitative biology and statistical genetics. His research since the late 1980s has focused on the genetics of complex traits related to human growth, development, aging and variation in susceptibility, severity, and progression of common diseases – especially cardiovascular disease and osteoporosis – in humans and nonhuman primates. A recurring interest has been identification and characterization of pleiotropic networks of disease risk factors, i.e., multiple traits affected by the same gene or set of genes.
More recent efforts have included analyses of data collected in two NIH-funded studies. One is a study of the effects of a high cholesterol high fat diet, on atherosclerosis risk factors and cardiovascular disease endpoints in pedigreed baboons. The other is a study of the effects of genes on co-variation between biomarkers of calcification and bone quality phenotypes in members of the Jirel population from eastern Nepal. Dr. Mahaney currently is conducting replication analyses of findings related to bone phenotypes with data from a large, longitudinal study of Mexican American families from San Antonio, Texas. He also is collaborating with a researcher from the University of Missouri in the genetic analyses of dental metric variation from the Jirel population. In the planning stages are studies of pleiotropic effects of genes affecting calcium metabolism on the development of atherosclerosis, diabetes, and obesity.
Currently, Dr. Mahaney also is the Coordinator of the Pilot Studies Program for the Rio Grande Valley Alzheimer’s Disease Resource Center for Minority Aging Research (AD-RCMAR) here at the UTRGV. Funded by the National Institute on Aging, the center’s goals include supporting the development of new and early-stage investigators who will contribute to research on Alzheimer’s disease and related dementias in the Hispanic population of South Texas.
With colleagues in biological anthropology, Dr. Mahaney also has “kept his hand in” the evolutionary biology game during his career, collaborating on studies of the genetics of developmental variation in the dentition and craniofacial complex of nonhuman primates.
