Spring 2020 Special Seminar: Engineering Genetic Circuits and Cell Fates: from Totipotency to Pluripotency to the Placenta

Seminar | January 21 | 10:30-11:30 a.m. | 290 Hearst Memorial Mining Building

 Jian Shu, Eric Lander Laboratory/Rudolf Jaenisch Laboratory Broad Institute of MIT and Harvard Whitehead Institute for Biomedical Research

 Bioengineering (BioE)

Reconstructing the circuits that control how cells detect environmental triggers and adopt specific fates and engineering these circuits to reprogram cellular functions are major challenges in biology. I will focus on two interconnected fundamental questions: 1) how to engineer cell fates and 2) how to measure the dynamic and complex biological ecosystems and understand the principles of...   More >

Expanding the Chemical Toolbox for Acoustic-based Imaging

Seminar | January 21 | 11 a.m.-12 p.m. | 120 Latimer Hall

 Jefferson Chan, Department of Chemistry, University of Illinois at Urbana-Champaign

 College of Chemistry

Many disease states are characterized by molecular level changes that occur before detectable symptoms have begun to manifest. In order to maximize treatment outcomes it is essential to accurately detect such alterations at an early stage. Chemical probes designed to selectively image such molecular processes have the potential to not only aid in disease diagnosis but can also provide unique...   More >

 Public Law & Policy Program at Berkeley Law

Panel on the impeachment process, at Berkeley Law.

Seminar 237, Macroeconomics: No Meeting Job Market Seminar

Harmonic Analysis and Differential Equations Student Seminar: On the Cauchy problem for degenerate dispersive equations

Seminar | January 21 | 3:40-5 p.m. | 740 Evans Hall

 Sung-Jin Oh, Berkeley

 Department of Mathematics

In plasma physics or fluid dynamics, one sometimes encounters a degenerate dispersive equation, i.e., a nonlinear dispersive equation whose dispersion relation is degenerate (i.e., vanishes at some points). A satisfactory understanding of the Cauchy problem for such equations is still missing, largely due to the appearance of challenging (and interesting!) phenomena from degenerate dispersion,...   More >

Commutative Algebra and Algebraic Geometry: The Fellowship of the Ring: Enumerating pencils with moving ramification on curves

Seminar | January 21 | 3:45-5 p.m. | 939 Evans Hall

 Carl Lian, Columbia university

 Department of Mathematics

We consider the general problem of enumerating branched covers of the projective line from a fixed general curve subject to ramification conditions at possibly moving points. Our main computations are in genus 1; the theory of limit linear series allows one to reduce to this case. We first obtain a simple formula for a weighted count of pencils on a fixed elliptic curve E, where base-points are...   More >

Getting Started in Undergraduate Research and Finding a Mentor Workshop

Workshop | January 21 | 4-5 p.m. | 9 Durant Hall

 Leah Carroll, Haas Scholars Program Manager/Advisor, Office of Undergraduate Research and Scholarships

 Office of Undergraduate Research

Getting Started in Undergraduate Research

If you are thinking about getting involved in undergraduate research, this workshop is a great place to start! You will get a broad overview of the research opportunities available to undergraduates on campus, and strategies for connecting with faculty members who can guide you.

Thematic Seminar: Diffeomorphisms of disks

Seminar | January 21 | 4:10-5 p.m. | 740 Evans Hall

 Alexander Kupers, Harvard

 Department of Mathematics

Disks are among the simplest manifolds but their groups of diffeomorphisms can be very complicated. I will describe the geometric techniques that were used to understand these groups in low dimensions, their relationship to stable homotopy theory and number theory in high dimensions, and recent breakthroughs in understanding their rational homotopy type. This talk will be aimed at a broad...   More >

Commutative Algebra and Algebraic Geometry: The Fellowship of the Ring: Singularities of generic projection hypersurfaces

Seminar | January 21 | 5-6 p.m. | 939 Evans Hall

 Takumi Murayama, Princeton University

 Department of Mathematics

Classically, it is known that every algebraic variety over an algebraically closed field is birational to a hypersurface in some projective space. Using generic linear projections, one can show that this hypersurface can be taken to have at worst nodal singularities in dimension one, or at worst ordinary singularities in dimension two. We present generalizations of these results to arbitrary...   More >
