Drew Rholl
Assistant Professor of Biology

At North Park since: 2011

Dr. Drew Rholl knows how well the North Park biology department provides its students with a strong foundation in the natural sciences and prepares them for graduate study. As an alumnus, he directly benefited from the department’s hands-on field and lab research opportunities, emphasis on scientific writing, and top-notch faculty advising, which set him on course to earn a PhD in microbiology at Colorado State University.

“Even though my first two years of undergraduate studies were at a school similar in size to North Park, I developed better relationships with my professors here," he says of his transfer-student experience. "The personal attention and guidance they provided is actually what made me want to be a professor in the first place. Now I am fortunate to be continuing this tradition.”

Now that he has returned to North Park as a faculty member, he is on the flip side—helping students learn and apply scientific methods to better understand the natural world. For example, he says, “I have periodic case studies in which groups work together to analyze a medical report and diagnose the case based on what was learned in class and by using external resources.” He also works with students in his collaborative research with Dr. Jeffrey Nelson and Dr. Matthew Schau on tick-borne pathogens in the Chicago area.

Dr. Rholl serves on the Pre-Professional Committee, which prepares students who are interested in dentistry, medicine, veterinary medicine, and other professions for the graduate admissions process through seminars, workshops, resource materials, individual advising sessions, and formal interviews. Applicants to professional schools from North Park have had a high success rate for the past 20 years.

“Our success rate for admission and success in professional schools is above average because North Park students are well prepared for graduate level academics. Our admissions rates into these schools are high in part because North Park's successful graduates have helped expand this reputation,” he says.

Dr. Rholl is a member of the American Society for Microbiology and TriBeta National Biological Honor Society.
