Dr. David A. Haukos is the Unit Leader and Associate Professor in the Division of Biology. He received his Ph.D. in Wildlife Science from Texas Tech University in 1991. His research efforts focuson the effects of environmental and habitat changes on wildlife populations. By extension, such changes are assessed in regard to delivery of ecological goods and services. His primary focus is on wetland habitats especially High Plains playas, Gulf coastal marshes, and western riparian areas, with additional investigations in prairie ecosystems. He principally concentrates on the influence of habitat quality and quantity on population dynamics of migratory waterbirds, prairie grouse, and grassland passerines. Of particular interest is the role of wintering and migratory stopover locations in future reproductive success of migratory birds, which includes assessment of cross-seasonal effects and multi-spatial scale modeling. In addition, he is involved in long-term development and assessment of novel models for environmental education.


Martha MatherDr. Martha Mather

Assistant Unit Leader
Professor, Division of Biology, Kansas State University
Ph.D. Zoology, Ohio State University, 1990

Dr. Martha Mather is the Assistant Unit Leader-Fisheries and Associate Professor in the Division of Biology. Her research program is focused on fish ecology that addresses applied problems. Specifically, problems related to the ecology of anadromous fish, processes that structure estuarine fish communities, how to use community ecology to devise fish sampling regimes that aid conservation, and integrated bio-social approaches to natural resource conflicts. These four topic areas fall under the overarching programmatic themes of applied aquatic ecology and how interdisciplinary approaches can be applied to natural resource problems. Conceptually, these topic areas are approached within these broader thematic areas by addressing the conceptual issues of how abiotic and biotic factors drive animal distribution and abundance, variations in patterns and processes across systems and through time, and the role of human impacts.

Dan SullinsDr. Dan Sullins

Post Doctoral Research Associate
Assistant Professor, Department of Horticulture and Natural Resources, Kansas State University

Dr. Dan Sullins obtained his B.S. in Wildlife and Fisheries Science from Texas A&M University in 2008. He received his M.S. in Forestry from Stephen F. Austin State University in 2013 and his Ph.D. from the Division of Biology at Kansas State University in 2017.


Bram VerhejienDr. Bram Verheijen

Post Doctoral Research Associate

Dr. Bram Verheijen earned his Ph.D. in Avian Ecology at Kansas State University in 2017, where he completed a project on the demographic responses of grassland songbirds to rangeland management in the tallgrass prairies of Kansas. Before that, he obtained his M.S. in Ecology and Evolution from the University of Groningen, the Netherlands. Here, he completed projects on the breeding site selection of Black-tailed Godwits in the Netherlands, and the effects of dam-removal on ecosystem functioning of the Peenetal wetlands in northeastern Germany.
