Professor of Cell Biology
His research and teaching interests include T-cell development and signal transduction; he has recently been examining the effect of phytochemicals on cells of the immune system. He has also begun a student research program in fermentation science.
His other interests include astronomy, general aviation, skydiving, and zymurgy.
This fermentation science course is designed to familiarize students with the current topics and procedures in brewing science. This upper-level course requires previous course and laboratory work in chemistry and microbiology. The course will focus on the study of the fundamental and applied sciences related to the use of microorganisms as production and processing agents. Specifically, we will examine the technological and biochemical aspects of the brewing process, including raw materials, malting, mashing, fermentation and maturation. In addition to lectures and discussion on the readings, the course will include extensive laboratory work. Students will work in small groups on a focused research project. Prerequisites: cell or molecular biology, chemistry, or microbiology.
Students in this course will learn about the biological function of selected human organs and systems through the study of actual medical cases. Not all human systems will be covered, but students will gain a good understanding of how diseases affect the body and how they are diagnosed. Working in small teams, students will develop diagnoses for medical cases through reviewing descriptions of patient histories, physical exams, and laboratory findings. A human biology text, medical texts on reserve, and Internet resources will help students track down information they need to solve these medical mysteries. Students will also learn to find and read scientific research articles on topics of their choosing and will learn to write analytical reviews of these articles. These reviews will form the basis of final papers in which students choose particular diseases or treatments to investigate in detail and present their findings to the class.
Health involves all aspects of our lives. Many people claim that the mind, body, spirit, and environment are all aspects that interact to influence a person's sense of well-being. High-quality health care must support the whole person. There are many terms used to describe approaches that are not considered conventional Western medicine. Complementary and alternative medicine (CAM) is a group of diverse medical and health care systems, practices, and products that are not presently considered to be part of conventional medicine. While some scientific evidence exists regarding some CAM therapies, for many there are important unanswered questions; some of these will be validated through well-designed scientific studies, while others risk exposure as simply fraudulent practices. Working individually and in small groups we will identify questions to pursue by reading and critiquing the primary scientific literature. The acceptance of these therapies is influenced by politics, history, personalities, and even their effectiveness. We will carefully evaluate some of these alternative therapies by examining the successes and failures.
Beer brewing is a complex process encompassing the manipulation of four essential raw materials: barley malt, brewing water, hops and yeast. Hops contribute significant attributes to the final beer and an understanding of the impact is crucial for the brewer and brewing scientist. Hop chemistry is only about 100 years old and after a flurry of activity in the early years, the focus of many brewing scientists has largely turned to other issues. There remain many hop-related questions of interest to the brewer that have not yet been addressed. We will, working in small groups, begin reading the literature closely and developing experimental protocols to answer some of these important questions. Preference will be given to those who have taken Zymurgy or Advanced Brewing Microbiology. Prerequisite: college-level Chemistry is required and Organic Chemistry is recommended.
