Online Learning Librarian
Librarian for the College of Health Human Sciences & Nursing

I'm the librarian for clinical science, health science, and nursing. I can help students with starting a research project, finding sources, including evidence-based research methods, and citing sources in APA. I work with faculty and instructors on integrating information literacy in the health science and nursing curriculum and designing in-person lessons and online tutorials for specific courses. As the online learning librarian, I also create videos and interactive tutorials to explore research concepts for any CSUDH students.
