       Huybers' Model of Glacial Cycles, Somyi Baek, School of Mathematics
       In a 2007 paper, Huybers introduced a simple model exhibiting the changes in amplitude and frequency seen in the climate record (the mid-Pleistocne transition).

       Huybers' Identification of Deglaciations, Cameron Thieme, School of Mathematics

Huybers introduced a computer algorithm to automatically pick out deglaciations from paleoclimate data. There are problems with using the algorithm on alternate data sets and on data sets from different geologic times.

       Huybers' Model as a Filippov System, Somyi Baek, School of Mathematics
       Huybers' model can be viewed as Filippov system with a discontinuity boundary containing crossing regions as well as both attracting and repelling sliding regions.
