Areas of Interest: 

Genetic epidemiology of epilepsy and other neurological disorders, post traumatic stress disorder and schizophrenia. Focus on gene localization through family-based linkage and association methods as well as next generation deep sequencing technology.

Dr. Bailey became interested in evolutionary biology and statistical genetics during her first degree working with insects. In graduate school she started studying Epidemiology and Human genetics. Most of her career has been focused on methods to find genes for complex traits using large extended pedigrees. These large, extended families allow the study of co-segregation of specific DNA and the clinical and subclinical phenotypes. Dr. Bailey studies families collected from various countries including Honduras, Mexico, Armenia and the United States, some families have over 100 members and more than 9 affected members.
