Some pictures taken while travelling in the context of my research. I also do other things in my life, such as powerlifting or long-distance hiking, and I might occasionally smuggle in some of these pictures here.

Nov 2022: Talking about the development of geodetic models of the earth and their importance for modelling other planets in the solar system. All while suffering in the aftermath of a questionable haircut. At Harvard's Earth and Planetary Science Department, photo taken by Junjie Dong.
