Megerle houses the lab sciences and mathematics at Wagner. Our science majors include Biology, Chemistry, Microbiology, Nursing, Physician Assistant, and Physics. Wagner also supports a graduate program in Microbiology, and an undergraduate Pre-Medical program. Important to note here is the new scanning electron microscope and a transmission electron microscope with which undergraduates can do their own research. Megerle also houses a neural development lab that specializes in zebrafish (danio rerio) histology. There is also a rooftop greenhouse. Labs as well as seminar rooms are located in this building. Faculty members maintain offices here, directly across from the labs.
