Research: 
My research interests are in genomics, evolutionary genetics, and comparative genomics.  Specifically, I have been interested in the mechanisms of genome evolution and its implication for adaptation and human disease.  Over the years, I have been involved in several studies looking at the genome diversity of admixture populations and participated in the analysis that identified candidate genes from GWAS and admixture scans. After collaborating with the 1000Genomes Project in Puerto Rico, we organized and published population genomic studies in other parts of the world that have not been addressed in global genome surveys, specifically in populations of Eastern Europe.  This work already demonstrated the potential for novel genetic discoveries in regions that remain understudied, and I am committed to further developing studies for human population genomics that contribute to understanding recent human evolution and personalized medicine. Currently, my lab is advancing research in Ukraine to discover new genetic factors that affect the development and pathology of type 1 diabetes (T1D), which could help predict disease, identify therapies to delay progression, and/or improve metabolic control in those living with T1D.  My other interest is in the evolution and conservation of endangered species. I am involved in studies focusing on genome assembly, variant analysis, and selection scans in wild and domesticated animals.
