B.S., Biochemistry, Juniata College, Huntingdon, PA

HS 309B

Dr. Haeusser is a Microbiologist with a graduate background in Molecular Cell Biology and an undergraduate degree in Biochemistry. At Canisius he has taught Introductory Biology I (Bio 111), Biochemistry & Cellular Biology I & II (Bio 211 & 212), Microbiology (Bio 307), Medical Microbiology and its Ecological Basis (Bio 305), and related labs. Within the Honors Program he has taught Biology in Fiction and Film (Hon 351).

Research in the Haeusser Lab focuses on bacterial cell division, particularly on factors expressed by viruses (bacteriophage) that infect cells and alter host shape or cytokinesis. As an essential and conserved process, bacterial cell division is an attractive target for novel antibiotic development.

Student research projects in the Haeusser Lab allow mentoring in genetics, microscopy, and biochemical techniques in the context of basic microbiology research with potential medical or environmental applications. Outside of ‘wet lab’ experiences, students may work with Dr. Haeusser in science communication through the American Society for Microbiology blog Small Things Considered (see link below), or in research on the inclusion of microbiology in literature and media (e.g. science fiction).
