Professional experience

Ryan Hansen received his bachelor's degree in chemical engineering from the Colorado School of Mines in 2001 and his doctorate from the University of Colorado, Boulder, in 2008. His doctoral dissertation focused on developing photopolymers for biodetection applications. He returned to the Colorado School of Mines as a post-doctoral researcher from 2009 to 2012, where he worked on developing microfluidic devices as a clinical assay for diagnosing bleeding disorders. In 2012, he moved to the Center for Nanophase Materials Sciences at Oak Ridge National Laboratory, where he performed research in nanobiotechnology. In 2015, Hansen joined the Tim Taylor Department of Chemical Engineering at K-State.


Hansen’s research group applies principles of chemical engineering, polymer science and microbiology to design novel biological materials, interfaces and soil amendments. His lab provides technologies that address sustainability in food, energy and water systems. Recent projects include investigating stimulus-responsive hydrogel materials for screening and separation of novel bacteria from environmental microbiomes, protective hydrogel coatings for functional bacteria and use of microbial soil amendments for promoting soil and plant health.
