Professor of Biology, Department Chair
on faculty since 1984
It is important to be able to integrate who I am as a Christian with who I am as a scientist, and to talk and learn about those things together with my students and other faculty.
Dr. Bob Boomsma ’77 has a desire to understand how the anatomical/structural aspects of animals and cells work with the functional/biochemical aspects. “I find the process of scientific discovery very enjoyable, as the limits of our understanding of the natural world continue to be pushed.”
What drew him to Trinity:
As a student at Trinity, Boomsma found himself drawn to the close, caring relationships that students have with other students and their faculty. “This chance for a real relationship with students and colleagues continues to be a big reason why I love being here.” He appreciates the strong emphasis on rigorous academic work and the freedom and ability to pursue his research interests here with students. “This is a great place to merge my love of teaching with my love of research discovery.”
His research interests include stem cell biology; cell signaling; regulation of development; hormonal control of reproduction; and Christian response to stem cells and cloning. He is currently studying bone marrow stem cells, particularly as they might be used to help hearts recover from the loss of blood flow that occurs during blockage of the coronary arteries leading to a heart attack. “Earlier research that I have done with colleagues at the University of Illinois at Chicago showed that the stem cells could prevent the loss of function in mouse hearts after heart attack. The research also showed that although the stem cells had a positive impact on the hearts, the heart themselves were still scarred, suggesting that the stem cells did not repair the hearts but instead improved the functioning of neighboring cells. My research now is focused on how stem cells might cause that improved function, including studies on cell migration, prevention of cell death, secretion of important regulatory factors, and gene expression.”
When he’s not teaching:
Boomsma plays the guitar and sings in his spare time. “I’m a member of a bluegrass gospel band and the church choir.” He also enjoys outdoor activities like jogging, downhill skiing, cross-country skiing, water skiing, and hiking.
