Epidemiology & Public Health
Education and Training
Dr. Takala received her B.S. in Zoology from Brigham Young University in 1999, after which she completed a two-year research fellowship in the Division of Parasitic Diseases at the Centers for Disease Control and Prevention. She received her Ph.D. in Molecular Epidemiology from the University of Maryland School of Medicine in 2006. After completing postdoctoral training in molecular evolution at University of Maryland and Arizona State University, she joined the School of Medicine faculty as part of the Multidisciplinary Clinical Research Career Development Program in 2008.
Dr. Takala’s primary research interests include molecular epidemiology, evolutionary biology, and population genetics/genomics applied toward understanding the evolution of the malaria parasite in response to the human immune system and interventions such as drugs and vaccines. Specific topics of interest include the effect of natural and intervention-induced selection on Plasmodium genetic diversity, associations between parasite and host genetics and disease, emergence and spread of resistance to antimalarial drugs and vaccines, and inference of parasite migration patterns to inform malaria eliminations strategies.
