SUMMARY
Dr. Petar Pajić is a postdoctoral researcher at the University at Buffalo, specializing in evolutionary genetics. He is broadly curious how structural variation, commonly found in genomes, contribute to evolution, function, and disease susceptibility. Dr. Pajić earned his doctorate in January 2025 in Dr. Omer Gokcumen’s labratory, where his dissertation, “Mucins provide insights into mechanisms of functional evolution,” examined the evolutionary forces shaping the variation and function of mucus-producing genes. He has experience in bioinformatics, genome sequencing, genetic analysis, and glycoproteomics. By integrating genomics, proteomics and functional biology, his interdisciplinary work aims to use basic science approaches to advance personalized medicine by uncovering key genetic mechanisms that shape human health.
