Talks

Over the course of my career, I've had the opportunity to give a few talks about the papers listed in the Papers section. Posted here are the Beamer presentations which accompanied these talks, or, when available, video footage of the talks. You may find them to be a helpful supplement to the papers.

• Environmental Evolutionary Graph Theory (a)
  • As presented at MIGHTY XLVII. Assumes a fair bit of mathematical knowledge: in particular, graph theory and elementary Markov chain theory.
• Environmental Evolutionary Graph Theory (b)
  • As presented at the RIT Undergraduate Research Seminar. Aimed at a non-mathematical audience.
  • Original talk available on Google Video.
  • Remarks. While preparing this talk, I was experimenting with rephrasing some of my concepts in order to make them sound more understandable without really changing their mathematical content. On comparing this talk to the talk above, the reader may be somewhat confused by the language changes (the reader who ventures on to read the paper will be delighted to find yet a third notation being used). In particular, the fixation probability ρ_B has been replaced with the “red holding power” h, where h = 1 - ρ_B. Vice versa for ρ_R.
• Environmental Evolutionary Graph Theory (poster)
  • As presented at the 2009 Joint Mathematics Meetings.
• Reconfigurable Systems and Intractability
  • As presented at the end of the 2008 REU. Assumes familiarity with Ghrist and Peterson's paper The Geometry and Topology of Reconfiguration, as well as some knowledge of group theory. Some informal background in theoretical computer science is provided.
