Undergraduate Research Opportunities with Dr. Larson
Dr. Larson’s work focuses on the function and cell interactions of human platelets. Platelets are the key cellular component in blood clotting, and are a major focus of therapies designed to prevent adverse cardiovascular events. He collaborates with Dr. Bill Harris of Omegaquant, Inc., Dr. Wally Whiteheart at the University of Kentucky, and Dr. Mike Holinstat at the University of Michigan to study the effects of omega-3 fatty acids on platelet function. He also collaborates and makes frequent visits to Dr. Owen McCarty’s lab at Oregon Health and Science University to explore links between platelet function and overall blood coagulation. Recently, he has teamed with Dr. Jennifer Gubbels and Dr. Karla Abbott at Augustana to study the interaction of ovarian cancer cells with platelets and differential platelet responses in Native Americans, respectively.
Dr. Larson's past research included a collaboration with Dr. Joe Italiano, Jr. at Brigham and Women’s Hospital/Harvard Medical School in Boston on the process of platelet biogenesis. Alumni Matt Braithwaite '11 and Jordan Anderson–Daniels '10 spent eight weeks with Dr. Larson in Boston working on how tissue matrix proteins in the bone marrow influence platelet development from precursor cells called megakaryocytes.

Dr. Larson specializes in cell biology and biochemistry, with interests in the intersection of science and society. He designs his class labs to maximize the use of the department’s substantial research equipment, including the confocal microscope, the flow cytometer, the tissues culture suite, and the DNA/protein imager, among others. He favors the process of research projects in the clasroom lab, including identifying new platelet agonists in pharmacology, a semester-long enzyme purification and characterization in biochemistry, and a month-long breast cancer cell culture unit in cell biology.
In the classroom, Dr. Larson closely examines real-world applications of biology, including the relationship of cancer treatments to cell function, the acquisition of knowledge for clinical medicine, and how science can often get misconstrued in and out of the laboratory. He encourages students to ask questions at every level, since it is the heart of all scientific endeavor.
