Dr. Christy C. Visaggi, Geosciences Lecturer at Georgia State University (PhD in Marine Biology, University of North Carolina Wilmington): Christy is a Lecturer in the Department of Geosciences at Georgia State University.  She is trained in geology, paleontology, marine ecology, and science education at the K-12 level and beyond. Her research focuses on understanding geographic variation in marine communities with implications for the fossil record and modern conservation efforts. Her pedagogical approaches utilize inquiry-based activities, collaborative work, and place-based learning to foster science-literate citizens who are able to recognize the importance and relevance of concepts in life and earth sciences to society. Christy has received awards for promoting underrepresented groups in STEM fields from the Ford Foundation and Association for Women Geoscientists. She has mentored undergraduates as part of a Research Experiences for Undergraduates (REU) program in biodiversity conservation (National Science Foundation Award #0755109). Christy is passionate about providing opportunities for students to engage in publishable research as part of their educational experience by contributing new data to address scientific problems with presentation of the results to a variety of audiences.
