BE/Bi 101. Order of Magnitude Biology. 6 units (3-0-3); third term. In this course, students will develop skills in the art of educated guesswork and apply them to the biological sciences. Building from a few key numbers in biology, students will "size up" biological systems by making inferences and generating hypotheses about phenomena such as the rates and energy budgets of key biological processes. The course will cover the breadth of biological scales: molecular, cellular, organismal, communal, and planetary. Undergraduate and graduate students of all levels are welcome. Instructors: Bois, Phillips. Offered alternate years; offered 2015-16.

BE/Bi 103. Data Analysis in the Biological Sciences. 9 units (1-3-5); first term. Prerequisites: CS 1 or equivalent; Bi 1, Bi 1x, Bi 8, or equivalent, or instructor's permission. This course covers a basic set of tools needed to analyze quantitative data in biological systems, both natural and engineered. Students will analyze real data in class and in homework. Python will be used as the programming language of instruction. Topics will include regression, parameter estimation, outlier detection and correction, error estimation, image processing and quantification, denoising, hypothesis testing, and data display and presentation. Instructor: Bois.

BE/Bi/MedE 106. Introduction to Biomechanics. 9 units (3-0-6); third term. Introduction to the basic concepts of applying engineering principles of solid and fluid mechanics to the study of biological systems. The course emphasizes the organismal, rather than the molecular, level of complexity. It draws on a wide array of biological phenomena from plants and animals, and is not intended as a technical introduction to medically related biomechanics. Topics may include fundamental properties of solids and fluids, viscoelasticity, drag, biological pumps, locomotion, and muscle mechanics. Not offered 2015–16.

BE 107. Exploring Biological Principles Through Bio-Inspired Design. 9 units (3-5-1); third term. Students will formulate and implement an engineering project designed to explore a biological principle or property that is exhibited in nature. Students will work in small teams in which they build a hardware platform that is motivated by a biological example in which a given approach or architecture is used to implement a given behavior. Alternatively, the team will construct new experimental instruments in order to test for the presence of an engineering principle in a biological system. Example topics include bio-inspired control of motion (from bacteria to insects), processing of sensory information (molecules to neurons), and robustness/fault-tolerance. Each project will involve proposing a specific mechanism to be explored, designing an engineering system that can be used to demonstrate and evaluate the mechanism, and building a computer-controlled, electro-mechanical system in the lab that implements or charaterizes the proposed mechanism, behavior, or architecture. Insructors: Dickinson, Murray.
