Alex Youcis
About Me
My name is Alex Youcis (the IPA transcription for my last name is juːkɪs). Currently, I am a postdoc at the National University of Singapore.
My Research Interests
Broadly speaking, my research interests are arithmetic geometry, rigid geometry, and \(p\)-adic Hodge theory. I am particularly interested in interactions of these topics with the theory of Shimura varieties and the Langlands program.
My CV
A more detailed account of my professional activities can be found in my CV.
