The combinatorics and extreme value statistics of protein threading [PDF]

open access: closedAnnals of Combinatorics, 1999
In protein threading, one is given a protein sequence, together with a database of protein core structures that may contain the natural structure of the sequence. The object of protein threading is to correctly identify the structure(s) corresponding to the sequence.

Sumsets, Zero-Sums and Extremal Combinatorics [PDF]

open access: closed, 2006
This thesis develops and applies a method of tackling zero-sum additive questions, especially those related to the Erdos-Ginzburg-Ziv Theorem (EGZ), through the use of partitioning sequences into sets, i.e., set partitions. Much of the research can alternatively be found in the literature spread across nine separate articles, but is here collected into

Remark on one problem in extremal combinatorics

open access: closedProblems of Information Transmission, 2012
We reduce the problem of determining the maximum number of permutations of a finite set such that any pair of permutations has at least t common transpositions to the problem of determining the maximum number of permutations of finite set such that any pair has at least t common fixed points. The latter problem was solved by the author in [1].
