Rob Brooker (Ph.D., Yale University) received his B.A. in biology at Wittenberg University, Springfield, Ohio, in 1978. At Harvard, he studied lactose permease, the product of the lacY gene of the lac operon. He continues working on transporters at the University of Minnesota, where he is a Professor in the Department of Genetics, Cell Biology, and Development and has an active research laboratory. At the University of Minnesota, Dr. Brooker teaches undergraduate courses in biology, genetics, and cell biology. In addition to many other publications, he has written two undergraduate genetics texts published by McGraw Hill.
Eric P. Widmaier received his Ph.D. in 1984 in Endocrinology from the University of California at San Francisco. His postdoctoral training was in endocrinology and physiology at the Worcester Foundation for Experimental Biology, and The Salk Institute in La Jolla, CA. He is currently Professor of Biology at Boston University.
Linda Graham is Professor of Botany and Environmental Studies at the University of Wisconsin-Madison. She received her Ph.D. in Botany from the University of Michigan, Ann Arbor. She has taught a nonmajors plant biology course each year for more than 20 years. She also teaches courses on the biology of algae and bryophytes, contributes to an introductory biology course for majors, and has taught marine botany on a remote tropical island.
Peter Stiling is a professor of biology at the University of South Florida at Tampa. He has taught classes in ecology, environmental science, and community ecology, and in 1995 he received a teaching award in recognition of classroom excellence in these areas. Dr. Stiling obtained his Ph.D. from University College, Cardiff, Wales, and completed postdoctoral research at Florida State University.
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.
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.
October, 2011: University of Oslo, Oslo, Norway. Biology Education: Past, Present, and Future. The University of Oslo had a one-day symposium celebrating its 150th anniversary. I was the opening speaker.

Currently, cleaner fish are one of the most widely used sea lice control strategies in Atlantic salmon aquaculture. Two species are currently being farmed in North Atlantic countries, ballan wrasse (Labrus bergylta) and lumpfish (Cyclopterus lumpus), and the sector in most countries is rapidly expanding towards self-sufficiency. The species are very different both in terms of their biology and life histories and, consequently, production and husbandry methods must be tailored to each species. There are numerous health challenges currently experienced in both species, with bacterial and parasitic diseases being the most prevalent, and cohabitation with salmon may increase the risk of disease. Good husbandry and routine health monitoring are essential, although treatment is often required when disease outbreaks occur. Ballan wrasse and lumpfish are both proven to be effective salmon delousers, although delousing efficacy can be variable in farmed fish; the provision of suitable habitat and acclimation to net-pen conditions may encourage natural behaviours, including delousing, and the use of operational welfare indicators can highlight potential welfare issues. Cleaner fish research is progressing rapidly, although much of the basic knowledge regarding the species' biology remains unknown. The simultaneous domestication of two new marine aquaculture species is a significant challenge demanding sustained effort and funding over a prolonged period of time. Research must focus on enhancing the robustness of the farmed stocks and increasing hatchery outputs to meet the urgent demands from the salmon sector and protect wild stocks from overfishing.
