            I am doing my PhD at the University of Pretoria under the supervision of Prof. Bernard Slippers from FABI, Prof. Jaco Greeff from the University of Pretoria and Dr. Jeremy Allison from Natural Resources Canada. My project is focused on the reproductive biology of the European woodwasp, Sirex noctilio. The wasp is an invasive pest native to Eurasia and was introduced in South Africa in the 1990’s. The pest has a long history of invasion in the Southern Hemisphere where it threatens pine plantations by decreasing wood quality and by killing trees. The main aim of my PhD is to understand the relationship between the reproductive biology of the wasp and its invasive success. I focus mainly on traits like sex ratio, reproductive behavior, sex determination systems and reproductive parasites. Part of my research is applied and aims at investigating new paths for the regulation of the wasp. Other chapters are more focused on theory and address questions related to invasive insect species and the effects of reproductive traits on adaptive capacity and invasive success.

Outside of science, my passions include languages, writing fiction and travelling. I am fascinated by the history of languages and how they evolve. The similarities between species and language evolutionary processes are particularly fascinating to me.  On my free time, I enjoy reading about linguistics and studying Korean. I also have had a passion for science fiction as long as I can remember. Writing novels and short stories is a hobby that helps me relax. Travelling and discovering new places and people is something that also brings me profound happiness. Wilderness or lively cities, scorching deserts or snowy mountains, each country has something new to offer and visiting them is always an opportunity for growth.

When I have the opportunity, I also like to meet young students and share my passion for science. I participated in Science fairs in 2018 and 2019 to encourage school kids to explore the world of science.
