Brief biography

Dr. Haro is Associate Dean for the College of Science and Health. His disciplinary research specializes in freshwater ecosystems, the biology of benthic invertebrates and fish, and landscape ecology. His primary area of study examines the behavioral ecology of benthic macroinvertebrates. He is also interested in how landscape change affects the connectivity of freshwater ecosystems and the biological consequences of non-point source pollution, including mercury. Dr. Haro was part of the faculty team that redesigned Bio 105 (General Biology). He is also the First Year Research Exposure (F.Y.R.E.) director and the former director (founding) of U.W.L.'s McNair Scholars Program. He has over 30 years of experience working with and developing programs for under-represented students in the S.T.E.M. fields.

Research and publishing

Prospective graduate applicants please note: I am not currently accepting new graduate students into my laboratory.  Please contact Dr. Eric Strauss ( for information about the graduate program in Aquatic Science.



John Manier, Roger Haro and Eric Strauss, all Biology; and Jeffrey Houser, USGS Upper Midwest Environmental Science Center; co-authored the article "Spatial and temporal dynamics of phytoplankton assemblages in the upper Mississippi River" in River Research and Applications and was accepted for publication by Wiley-Blackwell . Phytoplankton provide large quantities of organic carbon and biomolecules that support large river ecosystems. However, when certain groups become overabundant (e.g., cyanobacteria), they can pose a risk to human health and river biota. The purpose of this study was to examine the spatial and temporal dynamics of phytoplankton community composition within the upper Mississippi River. More specifically, we analyzed samples from main channel, impounded, and backwater areas of Navigation Pools 8 and 13 to examine lateral variability within each of these pools.

Roger Haro, McNair Scholars, received The Wisconsin State Council on Affirmative Action - 2018 Program Achievement Award at Wisconsin State Council on Affirmative Action Diversity Awards on Oct. 25, 2018 in Madison, WI. The Wisconsin State Council on Affirmative Action announced that UWL was chosen as the winner of the 2018 Program Achievement Award for the First Year Research Exposure (FYRE) program. The council was impressed with the informal learning community model that's employed to improve achievement and retention of first-year students of color. Haro and Chancellor Joe Gow attended the awards ceremony.
