Alice Hoersch, Ph.D.

Emeritus Professor
Biology, Environmental science
Holroyd Hall 045

Dr. Alice Hoersch was appointed Executive Assistant to the President in 1993, having started her career at La Salle University as assistant professor of geology in 1977. Currently a full professor, Dr. Hoersch also served as Director of Development and External Affairs for La Salle’s Institute for the Advancement of Mathematics and Science Teaching (1995–2001). Her previous years of educational leadership include a seven-year tenure as Associate Dean of the School of Arts and Sciences (1986–93). Dr. Hoersch also has experience as a visiting lecturer in the Department of Geology at Bryn Mawr College, from which she graduated in 1972. In addition, she served on her alma mater’s Alumnae Association Executive Board and is involved in numerous fundraising activities. She is a member of the Geological Society of America, the Philadelphia Geological Society, and Project Kaleidoscope, an organization devoted to improving undergraduate science education. She serves or has served on the Board of Trustees at Iona College and on its Executive and Presidential Search Committees. She is currently the Chair of its Academic Affairs Committee. She has also been a member of visiting teams for the Middle States Commission on Higher Education. Dr. Hoersch earned both a Master of Arts (1974) and Ph.D. (1977) from The Johns Hopkins University.

Geo 204 – Optical Mineralogy
This course is designed to prepare students for the study of materials using a petrographic microscope. Topics covered include the elementary principles of crystal optics, familiarization with the microscope, and mineral behavior in transmitted/polarized light. By the end of the course students are able to readily identify the major rock-forming minerals in thin sections and in grain mounts. In addition students learn how to find the necessary information to identify an unknown and perhaps never studied mineral. Students also explore topics in environmental mineralogy, including those involving mine wastes, landfills, nuclear waste, the atmosphere and the human body.

Geo 305 – Environmental Geochemistry
This course covers the origin of organic and organic pollutants in the terrestrial environment, the chemical processes that affect their fate and transport, the analysis of water and wastewater, and remediation techniques used to clean up sites.

Geo 401 – Igneous Petrology
This course is a review of the origin of the different igneous rock types based on the latest chemical, petrographic, and geophysical evidence.  It emphasizes the descriptive analysis of igneous rock composition and textures, interpretation of those compositions and textures, interpretations of igneous phase diagrams, and determination of cooling histories of common igneous rock types based on petrographic and phase analysis.

Geo 402 – Metamorphic Petrology
This course is a review of the origin of metamorphic rocks with a look at the physical, thermodynamic, and geochemical processes concerned with mineral recrystallization.  There is a detailed thin-section examination of various metamorphic zones.
