    The lecture was from noon to 1pm. Cyclone Vardah - the most powerful cyclone to hit Chennai in twenty-five years - was expected to hit Chennai at noon, and hit just as I was ending my talk. The wind and rain broke through the windows in the theater and flooded the stage during the 2pm talk.

  67. Suffix Trees Come of Age in Bioinformatics
    August 15, 2002 CSB02 Bioinformatics Conference, Stanford, CA. (Invited Lecture).

    This is an overview of some new uses of suffix trees and arrays in Bioinformatics. There are about 40 new papers in this area since 1997. I had intended to write a survey for the conference as well, but it never happened, and probably never will happen - there is just too much new, good work out there.

    This talk uses the Graph Realization approach (based on Matroid theory) to solve the Perfect Phylogeny Haplotyping Problem, rather than the Direct Approach in the later talks listed above.
