  • SAS 2015 Teaching Awards Ceremony

    University of Pennsylvania 200 College Hall

    Deans Office Representatives

    To applaud the extraordinary commitment of these individuals to the education of our students.  The winners of the SAS Teaching Awards will be honored at a School-wide reception. We hope that you will join us for the event as we celebrate teaching excellence in SAS.

  • Evolution Colloquium: "How Much Sex is Enough?"

    Carolyn Hoff Lynch Lecture Hall Chemistry Building, 231 S. 34th Street

    Professor Daniel S. Fisher (Stanford University)

    Sexual reproduction has many costs--especially the existence of lots of males, but sex, or more generally exchange of DNA is widely believed to have major advanages for evolution. Yet most of the arguments are rather qualitative: with multiple large and small numbers involved in evolutionary processes, quantitative understanding is essential...

  • SAS 2015 Teaching Awards Ceremony: Lindback Awards

    University of Pennsylvania, Hall of Flags Houston Hall, 3417 Spruce Street

    Deans Office Representatives

    Provost's Award Ceremony for Distinguished Ph.D. Teaching and Mentoring. The SAS community is invited to join in celebrating the honorees at the April 27 event detailed below. Warmest congratulations to these outstanding SAS teachers

    *Light refreshments and hors d’oeuvres will be served.*

  • Dissertation Defense: "The B-L MSSM from Strings to the LHC"

    David Rittenhouse Laboratory, Room 4N9

    Austin Purves, University of Pennsylvania

  • David Rittenhouse Lecture 2015: "Towards a Reliable Determination of eta-Earth with Kepler"

    David Rittenhouse Laboratory, Room A8

    Dr. Natalia Batahla (NASA)

  • Astro Seminar: "Mapping Magnetic Fields in Star Forming Regions with BLASTPol and BLAST-TNG "

    David Rittenhouse Laboratory, A6

    Laura Fissel (Northwestern)

    A key outstanding question in our understanding of star formation is
     whether magnetic fields provide support against the gravitational
     collapse of their parent molecular clouds and cores. Direct
     measurements of magnetic field strength using Zeeman splitting are
     extremely difficult and only a few clear detections have been made in
     high density molecular gas. Alternately, observations of polarized
     thermal emission from dust grains aligned with respect to the local

  • Dissertation Defense for Jing Cai: "Superior to One of Glass: Natural Gradient Index Lenses Via Patchy Particle Self-Assembly"

    DRL Room 3W2

  • Condensed Matter Seminar: "The life of a vortex knot: Linking coiling and twisting across scales"

    DRL A4

    William Irvine, University of Chicago

    Can you take a vortex loop - akin to a smoke ring in air - and tie it into a knot or a link?

  • An Introduction to Kirigami: Cutting, Folding, and Building with Triangles

    World Cafe Live, 3025 Walnut Street

    FeaturingVicki and William Abrams Professor of the Natural Sciences Randall Kamien; Professor Shu Yang; Xingting Gong, C'15; Daniel Sussman; Toen Castle; and Michael Tanis, members of a research team from the Departments of Physics and Astronomy and Materials Science and Engineering

    The team will explain how the mathematical rules they’ve outlined for this technique shows how to make all sorts of 3D structures from 2D designs. Attendees will also have a chance to try making their own kirigami creations.  It's an evening of engaging, stimulating conversation, with a Q&A session following each talk.

    Penn Café events are free and open to the public, but RSVPs are encouraged. Contact Gina Bryan at 215-898-8721 or email
