Research interests
As a keen population geneticist, I have a wide interest in applying molecular markers to the study the ecology, evolution and life history of species. Inter and intra specific gene flow, population genetic structure at the landscape scale, speciation processes are some research topics, among others, I focus on to better understand evolutionary and ecological processes that shape the actual biodiversity and use this knowledge to understand future trends in biodiversity change. I am also particularly interested in studying the consequences of anthropogenic pressure on ecosystem functioning by integrating population genetics with ecology.
Current Project
I am currently involved in a research project using sibship genetic assignment in bumblebee to estimate queen dispersal distances and nest density and survival in an agricultural landscape. This BBSRC founded research project leaded by Dave Goulson aim to identify key land use features (including mass-flowering crops) that affect bumblebee nest survival.
