  Thank you for visiting my website! My name is Semin Yoo (유세민, 劉世玟) and I am a mathematician working in the Discrete Mathematics Group at the Institute for Basic Science (CI: Sang-il Oum ).  Previously, I worked in the School of Computational Sciences at the Korea Institute for Advanced Study (mentor: Jeong Han Kim). I obtained my Ph.D. degree at the University of Rochester under the guidance of Jonathan Pakianathan and my Master's degree at Ewha Womans University* under the guidance of Sangjib Kim. (*: adding "s" is not a typo. The founder, Mary Scranton, named it.) I received my BS degree in mathematics and physics from Ewha Womans University. Some beautiful pictures of the above four places I've taken can be found here. And here is my CV. (updated on Apr. 1, 2024

  I like to study Combinatorics interlacing other research areas. Many of my research projects are related to counting problems in finite fields. They encompass a range of combinatorial problems that employ both algebraic and analytic techniques. Here are the areas and keywords I have been (will be) involved in so far. (For more details, see Publications.)

   Combinatorics / Discrete Geometry / Number Theory in Finite Fields: q-binomial coefficients, quadratic forms, (n,d,λ)-graphs, quasi-random graphs, threshold functions / Incidence problems / Diophantine tuples 

  I've also studied cluster algebras, representations of 0-Hecke algebras, and quasigroups for my research. I am broadly interested in other areas of combinatorics and I am very open to studying problems in other areas I feel interested in!

Some quotes I like for research: push the boundaries of human knowledge, carry forward the exploration of the universe, Life is good. 

-  Try to learn to breathe deeply, really to taste food when you eat, and when you sleep, really to sleep. Try as much as possible to be wholly alive with all your might, and when you laugh, laugh like hell. And when you get angry, get good and angry. Try to be alive.      -Ernest Hemingway
