Dr. Sedonia Sipes

Associate Professor, School of Biological Sciences & Director of Undergraduate Studies in Plant Biology

RESEARCH: My research focuses on the ecology and evolution of plant-insect interactions, specifically interactions between bees and their pollen and nectar host plants.

TEACHING: Courses currently in my teaching rotation include BIOL 213 Introductory Organismal Form and Function, BIOL 304 Evolution, PLB 300 Diversity of Plants, Algae, and Fungi, PLB 435 Plant Insect Interactions, PLB 117 Intro to Ethnobotany and Economic Botany (Univ. Core Curriculum), and PLB 480 Senior Seminar.
