Colm Mulcahy is a professor of mathematics at Spelman College, in Atlanta, where he has
taught since 1988. He's currently on leave in the DC area. Over the last decade, he has
been at the forefront of publishing new mathemagical principles and effects for cards,
particularly in his long-running bi-monthly Card Colm for the MAA. Some of his puzzles
have been featured in the New York Times. His book
<a href="http://www.crcpress.com/product/isbn/9781466509764" target="_blank">Mathematical Card Magic: Fifty-Two New Effects</a> was published by AK Peters/CRC Press in 2013.
Colm is a recipient of MAA's Allendoerfer Award for excellence in expository writing, for
an article on image compression using wavelets.

Biography: Michael Levitt is an American-British-Israeli biophysicist and professor of structural biology in
the Stanford University School of Medicine and a winner of the 2013 Nobel Prize in Chemistry. Born
in South Africa in 1947, Levitt earned his Bachelor of Science in Physics from Kings College
London and his Ph.D. in biophysics from Cambridge University. His research involves multi-scale
approaches to molecular modeling: Coarse-grained models that merge atoms to allow folding
simulation and hybrid models that combine classical and quantum mechanics to explain how enzymes
works by electrostatic strain. Levitt's diverse interests have included RNA and DNA modeling,
protein folding simulation, classification of protein folds and protein geometry, antibody
modeling, x-ray refinement, antibody humanization, side-chain geometry, torsional normal mode,
molecular dynamics in solution, secondary structure prediction, aromatic hydrogen bonds, structure
databases, and mass spectrometry. His Stanford research team currently works on protein evolution,
the crystallographic phase problem and Cryo-EM refinement. He is a member of both the Royal
Society of London and the U.S. National Academy of Science. Levitt also remains an active computer
programmer--"a craft skill of which I am particularly proud," he says.
After the talk there will be a reception and time for visitors to chat with Donelan and each other.
After the lecture, there will be a reception and time to chat with Engle and other guests.
