I do research in math and theoretical computer science, which is something that has unwittingly taken over a huge part of my life!
I couldn't live without daily cups of tea, some music (classical/opera/baroque, jazz, pop, rock...), and TV shows --- which I consider an art form. I like vegetarian, organic, healthy food (think pretentious stuff like quinoa, or azuki beans, or ...), but also raw fish.
I travel for work, and sometimes for myself, and on any occasion I hope to meet a friend but do not always know how to go about it. My favorite thing to do abroad, especially in cities, is to rent a bike and ride it all day long: it lets me get a feel for the city that I do not know how to get otherwise, and a healthy dose of euphoria.
I loved travelling to Japan, but I also have the most vivid memory of bikeriding throughout Manhattan in the middle of the night.
