I grew up in Stevens Point and attended UWSP as an undergraduate.  It is an honor for me to teach at this school in the Biology department.  Student mentorship and involvement in my field and lab work is the cornerstone of my professional interests.  My teaching and research interests are broad.  In conjunction with my duties as curator of fishes for the Becker Memorial Ichthyological Collection and my advisory role over the Ichthyologically focused student group (IASSSP), my students and I sample fishes on a regular basis to monitor local fish biogeography and we collect fish tissues for research using fish DNA.  We currently conduct research on many local ichthyological issues spanning the past 50 years using recently collected specimens and those housed in the fish collection.  Biological collections hold a wealth of biological information that can be used in countless research endeavors on evolution, biodiversity, biogeography, environmental degradation and even climate change.  Many of my students also work on various fish husbandry projects in my lab, recently we have focused the lab activities on husbandry and breeding of tropical species that could be of use in future aquacultural applications and several local species important in the baitfish industry.  Lastly, as I am a biological illustrator with recent work appearing in the Peterson Field Guide Series, I also oversee student interested in various biological illustration projects.  Most projects are focused on fishes.
