Site-Specific DNA Recombination and Fluid Vortex Reconnection


Speaker: De Witt Sumners, Florida State University

Location: 1147 MSB
Start time: Tue, Nov 3 2015, 3:10PM

Reconnection is a fundamental event in many areas of science, including interaction of fluid vortices and flux tubes in fluid mechanics and magnetohydronamics, and site-specific recombination in DNA. This talk will discuss the mathematical similarities between reconnection events in biology and physics, and the relationship between iterated reconnection and curve topology. In particular, the reconnection cascade from (2,2k+1) torus knots to (2,2k) torus links to the unlink of two unknotted circles observed in DNA is also observed in fluid vortex reconnections.

Professor Sumners will be visiting UC Davis on November 2nd and 3rd. Please let me know if you would like to schedule a meeting with him (email me at
