My research interests fall into two general areas: membrane transport and biology education. Our lab studies membrane transporters that cotransport metals across the plasma membrane; more specifically, we study transporters that cotransport Fe2+ and Mn2+ across the plasma membrane (MntH, also called Nramp1 and Nramp2 in humans). We are interested in the structure/function relationships of these types of transporters and have an ongoing collaboration with Dr. Preben Morth, who is an X-ray crystallographer. We are also interested in how the metal binding site in this transporter is able to evolve in a way that alters its metal specificity. In the past few years, I have also become interested in Biology Education research. I am just beginning to carry out such research at the University of Minnesota. My interests include the use of jargon, the impact of metacognition, and the use of technology, as they affect learning gains in biology classes.

My teaching philosophy is to rely on education research, particularly research that is focused on biology education, as a foundation for my teaching strategies. I am an advocate of “Flipping the Classroom” in which the majority of class time is spent on active learning exercises and projects. I am also an advocate of having students work in teams, where they can enhance each other’s learning, and motivate each other. I think that a good education in biology involves three things: (1) acquiring foundational knowledge; (2) developing skills that are required of biologists; and (3) cultivating one’s creativity. When we flip the classroom, the first goal of acquiring foundational knowledge is achieved by readings and online lectures that are done prior to coming to class. The other two goals (developing skills and cultivating creativity) are the focus of our in-class activities.
Favorite teaching innovation or approach
In the sections of Foundations of Biology (Biol2003) that I co-teach, and in my Genetics course (Biol4003), we have long-term projects that last about 8 weeks each. The goal of the long-term projects is to allow teams of students to dig more deeply into a scientific topic and provide an avenue for them to unleash their creativity. For example, in our Foundations of Biology course, one long-term project is that each team of 8 or 9 students develops a research proposal that revolves around membrane transporters. The teams propose two novel hypotheses, design experiments, and explain how they will analyze their results. In my Genetics course, one of the long-term projects is to devise a proposal to start a biotechnology company based on triplex DNA technology. Each team chooses two genes they would like to silence and then they describe: how they would conduct research to show the efficacy of silencing the gene; how they would conduct clinical trials, and how they would carry out commercialization. With regard to these long-term projects, each team submits weekly progress reports, which I review and provide feedback. I am truly inspired by the creativity and enthusiasm of our students while working on these projects.
