### 이준경

I'm an IMSS Research Fellow in Pure Mathematics at University College London. Before that, I was a Postdoctoral Researcher at Universität Hamburg, working with Mathias Schacht and a Postdoctoral Research Associate at University of Oxford working with David Conlon, who also supervised my PhD at the same university.

Some non-Korean speakers might wonder how to pronounce my name properly. The answer is [dʒungjʌŋ] (if this is too hard, then [dʒunkjʌŋ] may be an alternative) in terms of International Phonetic Alphabet, e.g., June + kyoung.

Here are my CV, Google Scholar profile, and papers:
