Java Darleen Villano

I am a fifth year Ph.D. candidate at the University of Connecticut (UCONN), working in mathemetical logic.My Ph.D. advisors are David Reed Solomon and Damir Dzhafarov.My email is javavill (at) uconn (dot) edu.Note: My entire first name is Java Darleen, but please feel free to just call me Java.

About me

I was born in the Philippines and moved to California when I was young. I grew up in California, and did most of my school there. I graduated from the University of California, Berkeley with a B.A. in Mathematics and a Logic minor in Spring 2019. I started at UCONN as a mathematics Ph.D. student in Fall 2019.In Summer 2022, I attended the IMS Graduate Summer School in Logic, where I learned a lot of logic and also had the chance to explore the beautiful country of Singapore.This past spring, I was at a BIRS 5-day Workshop in computable structure theory, analysis, and randomness, where I had the chance to work with wonderful people while being surrounded by sights of the Rocky Mountains.Outside of math, some of my hobbies include makeup, fashion, collecting cute items (stationary, plushies, etc.), and playing games.

Research interests

Most of my interests lie in computability theory. More specifically, I am interested in computable structure theory, algorithmic randomness, and reverse mathematics.Recently, I have been investigating the following relativization of computable categoricity: we say that a computable structure A is computably categorical relative to a degree d if for any d-computable copy B of A, there exists a d-computable isomorphism between A and B.


My CV is available here.---If you were wondering, I use the ModernCV template, which can be imported easily into an Overleaf project.

Fall 2023

  • SIGMA Seminar Fall 2023 // UCONN // Title: Randomness and Hausdorff dimension

  • CT Logic Seminar // UCONN // Title: Computable categoricity relative to a c.e. degree

Fall 2022

  • Ph.D. General/Oral Exam // UCONN // Title: Computable Categoricity Relative to a Degree
    The Ph.D. General/Oral Exam is the "oral part" of the qualification exams for Ph.D. candidacy at UConn. I took my oral exam in Fall 2022. For my presentation, I covered an overview of the investigations into computability categoricity, relative computable categoricity, and how these two notions are related. I also presented some results from my research project in investigating the structure of the c.e. degrees where there is a computable structure that is (or is not) computably categorical relative to it. My slides are available here.

I am the current President of the UCONN Chapter for the Association for Women in Mathematics.I was a speaker at the Mathematics Continued Conference in Fall 2022. The MCC seeks to give undergraduate students interested in math an opportunity to learn about graduate school and current research done by graduate students and faculty.
