Learning About Volcanos at Crater Lake

Currently I'm an adjunct professor emeritus for the City Colleges of Chicago. I was a tenured professor for 30+ years at Truman College. I love to learn and share my enthusiasm for learning. I have many interests. I enjoy learning about science, gardening, cooking and baking, linguistics and languages, drawing and painting, and literature. I believe we learn best when we are curious, excited, interested and engaged in our own learning processes.

Diversity, Equity, and Inclusion Statement

I support this statement adopted by the Physical Science and Engineering department at Truman College

We are committed to equity, inclusion, diversity and success of students and staff. We retain a fundamental belief that all people belong and deserve fairness, justice, and inclusivity. Our strength comes from our diversity. We celebrate the visible and invisible qualities that make each person unique including, but not limited to, culture, race, gender, age, sexuality, ability, religion, national origin, gender identity and other identities. In the classroom we focus on treating everyone with dignity, respect, kindness, compassion, and civility. We value a community where all individuals from all levels can participate, contribute, and have a voice.
