Gamma Delta Chapter
The Phi Sigma Biological Sciences Honor Society was founded in 1915 at Ohio State University. It currently has 86 active chapters with a total membership of more than 90,000.
The primary purpose of Phi Sigma is to promote academic scholarship in the Biological Sciences and to recognize and honor students who demonstrate academic excellence and involvement in scholarly research.
The Gamma Delta Chapter was established in 1984 by a group of students and faculty members. They wanted to provide recognition to outstanding undergraduate and graduate UC Davis students. Among the founders are Dr. Barbara Horwitz, past vice president, and Dr. John Horowitz, past treasurer.
The criteria for nomination to the Gamma Delta Chapter are greater than most chapters. At UC Davis, a minimum GPA of 3.5 is mandatory for undergraduates. This GPA requirement is significantly higher than the national requirement of 3.0 and is a reflection of the high caliber of students at UC Davis.
In addition, students invited to be members of our chapter must have conducted research in some area of the biological sciences.
