In the desert with the ordinals, amid COVID-19

My name is Zesheng Chen; my friends and family call me Jason. I am a PhD candidate at the Deparment of Logic and Philosophy of Science, UC Irvine.

I study notions of effective feasibility in (meta-)mathematics, what it means to have evidence for such notions, and their corresponding notions of randomness.

I approach these topics from the intersection of set theory and recursion theory, focusing on how theories of commonplace mathematics (such as the theory of computability) can often be lifted to higher mathematics (such as the theory of projective sets).

I am also competent in the history of set theory, especially the historical development of descriptive set theory.

My advisor is Toby Meadows.

I was born and raised in Shenzhen, China. I am a science communication enthusiast. You can find me on Twitter as @jasonchen0325, on Medium.com as @jasonzeshengchen, and on the Chinese Q and A website Zhihu as @ZS Chen. You can also reach me at “LegalFirstNameFirstLetterofLastName at uci.edu”
