Dr. Luis Espinasa

Associate Professor of Biology

Bio

I was born in Mexico, where I did my BA in Biology. I did my PhD in New York and since then I have for the most part remained in this country. My main teaching responsibility at Marist University is the course of Genetics. My area of expertise is cave biology, paleontology, and nicoletiid insect taxonomy. I am thoroughly involved in student collaborative scholarship. Throughout my career, I have published 53 articles with my students as authors or coauthors. Much of my work takes place in the field. I am also the director of the Marist Hiking Group, an informal group where faculty and students go hiking on the weekends to appreciate nature. My hobbies are hiking, caving, white water caving, rock climbing, and almost any outdoor activity. I am the father of two kids, one of whom graduated from Marist.
