I enjoy investigating how ecological and genetic factors are expected to influence the evolutionary process, and vice versa.
Recent/ongoing projects use mathematical models to investigate (i) the role of sex and epistasis in shaping genetic signatures of evolutionary rescue, (ii) the impact of haploid selection on the lability of sex determination systems, (iii) the effect of species interactions on evolution and persistence in changing environments, and (iv) how non-Mendelian inheritance affects the likelihood of crossing valleys of fitness created by epistasis.
Past projects involved actual fieldwork on real plant communities and wild birds.
