In 1996, he received his university's highest teaching award and in 2001, its Ignatian Pedagogy Award. In 2004, the Helen Way Klingler College of Arts and Sciences honored him with its Faculty Award for Excellence in Advising. These awards would not have been possible without the wonderful students and colleagues he has had the honor of working with during his years at Marquette.
For over twenty years, in collaboration with practicing physician/scientists, physiologists, cell biologists and biomedical engineers, Dr. Krenz studied various nonrespiratory functions of the lung; that is, what the lung does BESIDES gas exchange. In particular, he applied mathematics to (mathematically!) model cellular metabolism and hemodynamic properties of the lung. These investigations involved several approaches, such as ongoing work incorporating available vessel morphometric data within the framework of "simple" deterministic homogeneous vascular networks, as well as nondeterministic heterogeneous vascular networks. In addition to the hemodynamic studies, he investigated the uptake and interaction of drugs with the endothelial cells of the lung capillary bed. That research was funded by the National Institutes of Health and the Department of Veteran's Affairs. Now, he is delighted to be working on the National Science Foundation S-STEM project entitled COSMIC -- Change Opportunity - Start Masters In Computing.
