Phi Sigma

Who we are

Phi Sigma is a national society that was founded in March 1915 at Ohio State University to promote academic achievement and research in the biological sciences. There are currently 32 active chapters with approximately 50,000 members. Phi Sigma is the only nationally recognized honor society for both undergraduates and graduates in Biological Sciences. On the campus of Illinois State University the Phi Sigma Biological Science Honors Society is represented by the Beta Lambda Chapter (a registered student organization) which was founded in 1966. Phi Sigma is devoted to the promotion of scholarship and research in the Biological Sciences. To this end the Beta Lambda Chapter of Phi Sigma works closely with the School of Biological Science and is a sponsor of the weekly school seminar series, and the annual research symposium. The Beta Lambda Chapter of Phi Sigma also holds an annual grant competition to provide research funds to both graduate and undergraduate students. Visit our facebook

Phi Sigma Beta Lambda Chapter promotes the engagement of undergraduate and graduate students in biology research and academic pursuits. To achieve these goals, we sponsor an annual research symposium in the spring, provide $10,000 in funding for student research in the biological sciences, and fund seminars from speakers in the biological sciences. In addition to supporting students at ISU, we also strive to support K-12 and community-based efforts to engage students in authentic experiences related to the biological sciences. The grant application below is intended to support such efforts in McLean County.  Click the link below to access the Phi Sigma Beta Lambda External Grant Application.
