Principles of Biology
9 units (4-0-5)

third term
A host of new technologies have led to an explosion of fascinating data across the hierarchy of biology, from molecules to ecosystems, as well as the integration of biology with other sciences, including geology, physics, chemistry and mathematics. This course provides an introduction to the most exciting themes of modern biology through a series of case studies. Each of these examples, whether the examination of the critical role of keystone species in ecology or the resolution of key puzzles of modern biogeography using DNA sequencing or the advent of super resolution microscopy which provides an astonishing dynamic view of cells and the viruses that infect them, serves to demonstrate the overarching principles of modern biology.

We will explore programmability, complexity, simulation of, and reasoning about abstract models of chemical reaction networks, molecular folding, molecular self-assembly, and molecular motors, with an emphasis on universal architectures for computation, control, and construction within molecular systems. If time permits, we will also discuss biological example systems such as signal transduction, genetic regulatory networks, and the cytoskeleton; physical limits of computation, reversibility, reliability, and the role of noise, DNA-based computers and DNA nanotechnology. Part a develops fundamental results; part b is a reading and research course: classic and current papers will be discussed, and students will do projects on current research topics.

Introduction to Systems Biology
6 units (2-0-4)
|
first term
Prerequisites: Ma 1abc, and either Bi 8, CS1, or ACM 95 or instructor's permission.
The course will explore what it means to analyze biology from a systems-level point of view. Given what biological systems must do and the constraints they face, what general properties must biological systems have? Students will explore design principles in biology, including plasticity, exploratory behavior, weak-linkage, constrains that deconstrain, robustness, optimality, and evolvability. The class will read the equivalent of 2-3 scientific papers every week. The format will be a seminar with active discussion from all students. Students from multiple backgrounds are welcome: non-biology or biology students interested in learning systems-level questions in biology. Limited enrollment.

Stem Cells and Hematopoiesis
9 units (3-0-6)
|
third term
Prerequisites: Graduate standing, or at least one of Bi 114, Bi 117, Bi /Be 182, plus molecular biology.
An advanced course with classes based on active discussion, lectures, and seminar presentations. Development from embryos and development from stem cells are distinct paradigms for understanding and manipulating the emergence of ordered biological complexity from simplicity. This course focuses on the distinguishing features of stem-cell based systems, ranging from the natural physiological stem cells that are responsible for life-long hematopoiesis in vertebrates (hematopoietic stem cells) to the artificial stem cells, ES and iPS cells, that have now been created for experimental manipulation. Key questions will be how the stem cells encode multipotency, how they can enter long-term self-renewal by separating themselves from the developmental clock that controls development of the rest of the organism, and how the self-renewal programs of different stem cell types can be dismantled again to allow differentiation. Does "stem-ness" have common elements in different systems? The course will also cover the lineage relationships among diverse differentiated cell types emerging from common stem cells, the role of cytokines and cytokine receptors in shaping differentiation output, apoptosis and lineage-specific proliferation, and how differentiation works at the level of gene regulation and regulatory networks. Given in alternate years; offered 2016-17.

12 units (2-6-4)
|
second term
Prerequisites: Bi/BE 177 or a course in microscopy. Bi/BE 177 may be taken concurrently with this course.
Discussion and laboratory-based course covering the practical use of the confocal microscope, with special attention to the dynamic analysis of living cells and embryos. Course will begin with basic optics, microscope design, Koehler illumination, and the principles of confocal microscopy as well as other techniques for optical sectioning such as light sheet fluorescence microscopy (also called single plane illumination microscopy, SPIM). During the class students will construct a light sheet microscope based on the openSPIM design. Alongside the building of a light sheet microscope, the course will consist of semi-independent modules organized around different imaging challenges using confocal microscopes. Early modules will include a lab using lenses to build a cloaking device. Most of the early modules will focus on three-dimensional reconstruction of fixed cells and tissues. Later modules will include time-lapse confocal analysis of living cells and embryos. Students will also utilize the microscopes in the Beckman Institute Biological Imaging Facility to learn more advanced techniques such as spectral unmixing and fluorescence correlation spectroscopy. No prior experience with confocal microscopy will be assumed; however, a basic working knowledge of microscopes is highly recommended. Preference is given to graduate students who will be using confocal microscopy in their research. Given in alternate years; not offered 2016-17.

Special Topics in Biology - The World in 2050
9 units (3-0-6)

third term
This course will use computer modeling methods to explore the way in which Malthusian limits may apply to continued growth of the human population and of global economic activity. Modeling strategies will be similar to those offered in a book entitled Limits to Growth (as sponsored by the Club of Rome and published in 1972), but dozens of other, more recent perspectives will be considered. The real goal is to help students develop some facility for careful, critical thought about the long-term future, constantly asking: How much can we reasonably predict on this type of time scale? And how should this affect our current and future behavior? What can be done?

Special Topics in Computational Biology - Introduction to Sequence Analysis and Motif Discovery
9 units (3-0-6)
|
first term
Prerequisites: Bi 8, CS 2, or instructor's permission.
Sequence analysis and motif discovery have been two cornerstones of computational biology and bioinformatics since the early days of these sciences, and their importance has been increasing with the development of next-generation sequencing techniques, the ensuing flood of large-scale genomics and epigenomics data, and the need of analyzing these valuable sequence data efficiently. This course will introduce key computational, information-theoretic, and probabilistic methods for sequence analysis and motif discovery including popular models such as Markov models, Hidden Markov models, Bayesian networks, or maximum entropy models as well as popular algorithms such as the expectation-maximization algorithm and its stochastic relatives or the Gibbs sampling algorithm and other Markov chain Monte Carlo methods. Students of this course will develop a solid understanding of these algorithms, profound skills of deriving and implementing them, and the virtuosity of applying them to diverse problems of sequence analysis and motif discovery. Undergraduates can enroll with instructor's permission.
