Ohanna is a CANSSI STAGE postdoctoral researcher at the University of Toronto in the Dalla Lana School of Public Health. She applies statistical methods in DNA methylation and whole genome sequencing data to understand the epidemiological, genetic, and epigenetic determinants of complex diseases. A molecular biologist by training, Ohanna received a master’s and PhD degree in Genetic Epidemiology from the Oswaldo Cruz Institution in Brazil, where she studied genetic susceptibility of infectious diseases in admixed population. For her bachelor’s degree, Ohanna received a master's and PhD degree in Cellular and Molecular Biology from the Oswaldo Cruz Foundation (FIOCRUZ/Brazil). Her dissertation focused on the Genetic Epidemiology of Infectious Diseases. Currently, she is a Postdoc of the CANSSI Ontario STAGE HostSeq Project in Dalla Lana School of Public Health at University of Toronto, studying genetics and epigenetics of complex traits.
