I am currently a postdoctoral researcher at Memorial Sloan Kettering Cancer Center. Previously, I was a PhD student in the mathematics department at Stony Brook University. I also support communism, luddism, and anarchism. That is, the freedom to work for the community and not for capital, with technological tools in the hands of users, despite the state's unwavering protection of the ownership class' passive enjoyment of the fruits of the people's labor.
