Profile

My research interest lies in the field of combinatorics and its application. I am particularly interested in the interface between discrete mathematics and biology. In the past few years I have been working on biological issues, such as evolution and cellular differentiation, from a mathematical perspective.

arXiv:1904.12432 [math.CO]      Apr 2019
'Tree-based' phylogenetic networks provide a mathematically-tractable model for representing reticulate evolution in biology. Such networks consist of an underlying 'support tree' together with arcs between the edges of this tree. However, a tree-...

arXiv:1811.05849 [math.CO]      Nov 2018
Attempting to recognize a tree inside a phylogenetic network is a fundamental undertaking in evolutionary analysis. Therefore, the concept of "tree-based" phylogenetic networks, which was introduced by Francis and Steel, has attracted much attenti...
