No prerequisite.
While biologists seek general principles that explain the common characteristics of all organisms, we too often ignore that most obvious of traits: an organism's size. In this course, we will explore how size determines the form, function, pace and complexity of life. Our questions will span realms from the minuscule (how do bacteria swim?) to the gigantic (is Earth a super-organism?) to the fantastic (what would it cost to feed King Kong?). Living things span an amazing range of sizes, and by using size as a lens for studying life, we will develop a quantitative framework for comparing not just apples and oranges, but bacteria and blue whales. Surreal perspectives on biology such as Swift's "Gulliver's Travels" and films like "A Fantastic Voyage" will further highlight the truly amazing nature of biological reality. Does not count toward the major or minor. No prerequisite.

The world around us is teeming with microorganisms, many of which are capable bringing us to our knees. Despite this looming devastation, most individuals manage to remain healthy, not succumbing to the ever-present pathogens in our environment. Immunology is the study of the cellular and molecular mechanisms employed to protect against infection. The cells and organs of the immune system are many and, consistent with this diversity, play many important roles in health and development. Every day, components of the immune system must identify harmful invaders and eliminate them, a process that requires critical distinction between host vs. harmful cells. They also provide long-lived protection against recurring infection. In this class, we will embark on a journey through the immune system. We will explore the mechanisms employed by the innate immune system to provide first response to foreign invaders. Additionally, we will dissect the complex processes by which cells of the adaptive immune system recognize and respond to pathogens and establish long-term immunity. Lastly, we will explore the consequences of impaired immune response in a variety of contexts. This counts toward the upper-level cellular/molecular biology requirement for the major. Prerequisite: BIOL 255, 263, 266 or 238. Generally offered every other year.

We consider how to assess difficulties and limitations in experimental strategies due to design, equipment, organism selected and so on. The course provides a detailed understanding of selected modern research equipment. Students select their own research problems in consultation with one or more biology faculty members. This course is designed both for those who plan to undertake honors research in their senior year and for those who are not doing honors but want practical research experience. A student can begin the course in either semester. If a year of credit is earned, it may be applied toward one laboratory requirement for the major in biology. This course is repeatable for credit. Prerequisite: BIOL 109Y–110Y and 116 and permission of instructor.
This course provides the student with the opportunity to pursue an independent investigation of a topic of special interest not covered, or not covered in depth, in the current curriculum. The investigation, designed in consultation with the chosen faculty mentor, may be designed to earn .25 or .5 unit of credit in a semester. BIOL 393 is ordinarily is a library-oriented investigation. (For laboratory-oriented independent research, see BIOL 385.) Normally, students receive credit for no more than two semesters of individual study. Individual study does not fulfill the natural science diversification requirement, nor does it count toward the requirements for the major. Because students must enroll for individual studies by the end of the seventh day of classes, they should begin discussion of the proposed individual study well in advance, preferably the semester before, so that there is time to devise a syllabus and seek departmental approval before the established deadline.
In this capstone seminar, students explore current research topics in biology. Each section will explore a different fundamental concept in biology that spans the range of biology from ecosystems to molecules. Students analyze, critique, and integrate information from research articles they connect specific studies to broader biological questions and they propose future work that refines and extends prior studies. Student communicate their insights and analyses in both oral and written formats. Assignments include short essays, student presentations, student-led classes, peer review, and writing workshops. This course counts toward the upper-level lecture course requirement for the biology major. Prerequisite: senior standing and biology or molecular biology major.
