Principal Investigator
Natalie Krahn
In the vast realm of scientific exploration, Natalie stands as a beacon of brilliance. Her postdoctoral research at Yale University with Dieter Söll led her to chart unexplored territories in synthetic biology, akin to a mariner drawn to the mysteries of the uncharted sea. Developing a profound affinity for the 21st amino acid, selenocysteine, she harnessed its potential as her guiding star. Prior to this, her foundation in biophysics was laid at the University of Manitoba under Jörg Stetefeld's guidance. It was there where she mastered the complex dance of protein-protein and protein-nucleic acid interactions. Her adventurous and inquisitive spirit propels her quest, continuously exploring the vast ocean of scientific knowledge.

Antavius Cain

Ant is undertaking his PhD voyage with the spirit of a seasoned navigator setting sail on uncharted waters. This voyage isn't about traversing oceans or seeking hidden treasures, but about charting the unexplored territories of biochemistry. Each challenge encountered is not an obstacle but a beacon, illuminating the path towards new discoveries. Guided by a compass of insatiable curiosity and fortified by an armor of unwavering diligence, Ant is committed to demystifying the complexity of selenoproteins. His journey, a tale of academic exploration, is as thrilling as any adventure saga, and each revelation he uncovers is a treasure in the realm of scientific understanding. Selenoproteins are SUUUUUPPPPPPERRRR!
Graduate Researcher
Joshua Weiss

Josh is a biochemistry and molecular biology Ph.D. student. Originally from Rochester, NY, he developed an interest in biochemistry and synthetic biology inspired by his navigation through Celiac disease. In his undergraduate at Saint Michael’s College, he researched novel CRISPR-Cas systems and neurodegeneration while also becoming a star competitor on the men’s tennis team. Now at UGA, Josh’s course is set to engineering a synthetic translation system to expand selenoprotein research. Outside of the lab, he enjoys playing basketball, running, teaching tennis, and supporting science outreach initiatives
