Areas Of Expertise

Dr. Rishel’s professional interests lie in clinical work and research with at-risk populations and those affected by substance abuse. He also enjoys teaching, as reflected in his philosophy of teaching statement below. 

Teaching Philosophy

In the classroom, I attempt to explain complex material in a manner that is digestible and that evokes critical thinking and enthusiasm. I accomplish this by providing “real world” examples, including my own experiences, in order for students to bridge theory with application. I also value class discussions and small group exercises greatly, as each student brings with them a unique set of experiences derived from diverse backgrounds which enhance the learning process. I believe it is my job as a teacher to facilitate class discussions in such a way that everyone feels safe in sharing their ideas so that all class members can learn from each other. I want to provide my students with the same opportunity I had as a graduate student to grow as a person both professionally and personally. My goal is to establish a learning environment that enhances each student’s critical thought process and increases their awareness of individual and cultural differences among the people with whom psychologists work, including ourselves. I also believe that part of my role as a teacher is to guide students toward specific areas of psychology where they can utilize their unique talents to advance the field of psychology. My hope is that I am able to play a part in producing the highest quality psychologists entering the field; psychologists with whom I aspire to collaborate in the future.
