David Gay's Home
I am a senior researcher at Euclid Lab, an Associate Professor in the Mathematics Department at the University of Georgia, and the lead mentor for Camp Euclid. My main area of research is 4-dimensional geometry and topology. I obtained my Ph.D. in mathematics from the University of California, Berkeley under the supervision of Robion Kirby and have worked as a research mathematician since 1999.

- Research: I have been working since 1996 on problems related to constructions of smooth 4-manifolds with additional geometric structures related to symplectic and contact geometry. I am currently wrapped up in an active collaboration with Rob Kirby, thinking about using generic maps from 4-manifolds to the 2-sphere to get at a combinatorial/topological understanding of smooth 4-manifold invariants. Using these techniques we recently discovered the right way to generalize the notion of a Heegaard splitting in dimension 3 to the 4-dimensional setting; where 3-manifolds are split into two handlebodies, 4-manifolds are now trisected into 3 4-dimensional 1-handlebodies. Other recent, more-or-less ongoing and/or potential collaborators include Joan Licata, Margaret Symington, Andras Stipsicz, Aaron Abrams, Valerie Hower, Olguta Buse, Bruce Bartlett and Thomas Mark.
- Blog: You can read my research blog here.
- Teaching: I have taught a wide range of university-level mathematics courses, ranging from graduate courses in knot theory and algebraic topology to college algebra courses and courses for future elementary and high school teachers. I am currently teaching "Foundations of Geometry I" and "Calculus for Science and Engineering III". Next semester (Spring 2014) I will be teaching "Foundations of Geometry II" and "Multivariable Calculus".
- Outreach: I have given many mathematics enrichment talks at local high schools in communities as diverse as rural Quebec and the townships of Cape Town. I am currently helping the University of Georgia MathCounts Outreach program run an Athens Math Circle, although in truth all the work is done by UGA undergraduate and graduate students.
