Dr Simon Segar

BSc, MSc, DIC, PhD

Lecturer in Entomology

I have broad research interests  currently pursue two major research programmes: i) the evolution of host use and chemical ecology of insect herbivores (Segar et al., 2017a; Volf et al., 2018) and ii) population genomics and speciation in figs and their pollinating wasps along the slopes of a tropical mountain (Segar et al., 2017b; Souto-Vilaros, 2018). I also conduct research relating to arthropod phylogeny (Segar et al., 2012), community phylogenetics (Segar et al., 2013) and mutualism stability (Dunn et al., 2008). More generally I am driven by a desire to understand plant and insect diversity, and the processes responsible for generating it. This goal necessarily requires a multi-disciplinary approach because extant diversity is a result of both evolutionary and ecological dynamics, and selection on myriad traits responsible for mediating ecological interactions.
