Justin Sipiorski


Professor of Biology Justin Sipiorski is a UW-Stevens Point alum. His broad research interests span across the past 50 years of ichthyological issues 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 Dr. Sipiorski’s students also work on various fish husbandry projects in the lab. They sample fishes on a regular basis to monitor local fish biogeography and collect fish tissues for research using fish DNA. Student mentorship and involvement in his field and lab work is the cornerstone of Sipiorski’s professional interests. Professor Sipiorski publishes his biological illustrations, with recent work appearing in the Peterson Field Guide Series.
