Here is my CV.
RosaWinter
I am a PhD Student in arithmetic geometry, under the supervision of Martin Bright and Ronald van Luijk at Universeit Leiden. My research is on the density of rational points and the configurations of lines on del Pezzo surfaces of degree one, and torsion points on elliptic fibrations. My thesis is scheduled to be finished in the spring of 2020 and I am currently looking for postdoc positions starting in the fall of 2020.

Teaching


From 2014 until 2016 I was a mathematics teacher at Calandlyceum Amsterdam, as part of the traineeship Eerst de Klas.
