This news item from Cornell Research is about: “Genotyping mice, collecting tumors, weighing tumors, it’s a lot of what I do,” says Irma Fernandez—a third-year graduate student in Biochemistry, Molecular and Cell Biology at Cornell. She chuckles as she explains the routine of her important tasks as if to imply that this is not what most people do. “I work on one of the more unusual projects in my lab,” Fernandez confesses. Mirroring the uniqueness of her project, Fernandez’s status as a graduate student is also distinctive. She is a joint student in the labs of Robert S. Weiss, Biomedical Sciences, and Hening Lin, Chemistry and Chemical Biology. Whereas most people work with one major principal investigator (PI) on their research, Fernandez works with two, the product of a long-standing collaboration with Weiss, Lin, and Richard A. Cerione, Molecular Medicine/Chemistry and Chemical Biology. Having dual PIs allows Fernandez to combine the biochemistry focus of the Lin lab with the molecular biology and genetics focus of the Weiss lab—her key areas of interest.
