Kathleen Tweeten


<div class="line" id="line-3"><span style="font-family: Arial; font-size: 100%;">Kay Tweeten is a professor of biology at St. Catherine University. Her courses in molecular biology, cell biology, and immunology feature problem-based learning, case studies, and student-designed research projects. She has collaborated with numerous students in her research laboratory on cellular and molecular analysis of regeneration, degrowth, sexual reproduction, and ploidy levels in populations of the freshwater annelid, Lumbriculus. She involves students in experimental design, data collection and interpretation, and dissemination of results. The research environment provided allows students autonomy in their thinking and helps them explore their potentials as scientists. They learn the value of perseverance through frustrations that accompany experimentation, of doing research with integrity and thoroughness, and of embracing how mistakes may provide for progress. She has received Teaching Awards, the Myser Family Faculty Mentoring Award, and was Endowed Chair in the Sciences. She has expertise in collaborative research, mentoring, faculty development, and curriculum innovation.</span></div>
