Dr. Sara Choung's interest in chemistry was sparked in high school and she went on to study chemical engineering at MIT and UC Berkeley. She discovered her love of teaching and mentoring undergraduate students during graduate school. After doing research at Argonne National Laboratories, she started her teaching career at PLNU in 2004. Choung also enjoys her role as the pre-health advisor, working with students who plan to attend various health professions schools. She grew up in Illinois and misses the Chicago pizza, but not the weather.

Dr. Heidi Woelbern has been at PLNU since 2008. She teaches numerous courses, including Introduction to Biotechnology, Introduction to Cell Biology and Biochemistry, Research Methodology, Genetics and Microbiology. Her research interests have focused on the role of nuclear receptors, a subclass of transcription factors, in regulating various metabolic diseases (diabetes, heart disease, lipoprotein metabolism) as well as cancer.

Kerri Sevenbergen has been at PLNU since 2000, when she first joined the biology and chemistry departments as an adjunct professor. In 2003, she was hired as a full-time instructor and lab manager for those departments. In 2014, in response to the growth of both departments, Sevenbergen became a full-time faculty instructor and lab manager solely for the biology department.

Dr. Dawne Page joined the faculty of PLNU in 2002 and became chair of the Department of Biology in 2009. She enjoys teaching undergraduate and graduate students, and she has a long-term interest in teacher professional development. Her research interests are in the field of immunology.

Summer Research

Dr. Mike Mooring has been conducting behavioral ecology research since 1985, mounting field studies of African antelope, North American ungulates, and Neotropical mammals. During this time, he has worked in six countries and five states, navigating the logistical challenges of field research in a variety of contexts. His doctoral research focused on the parasite-defense behavior of impala in Zimbabwe, South Africa, and Namibia. Mooring received his Ph.D.

Dr. Michael McConnell taught biology and chemistry at PLNU from 1978 through 2018. The biology summer research program he established in 1979 has operated for over 40 consecutive summers, giving 600+ PLNU undergraduates an opportunity to engage in original research. Although now retired from teaching, McConnell continues to mentor PLNU students in summer research.

Dr. Jennifer Lineback has been teaching at PLNU since 2012. Previously, she spent the first 10 years of her professional life teaching biology and environmental science at the high school level in schools in several different states (Connecticut, Florida, and Maryland) and overseas (Trinidad). Lineback considers herself blessed to be part of the PLNU community, teaching in the School of Education and the Department of Biology. Such a "split" professorial position allows her to cultivate her two passions: biology and teaching.
