I am Afif^, currently a Postdoctoral Research Associate at Ulsan National Institute of Science and Technology (UNIST), Ulsan, South Korea. I obtained PhD in 2026 from University of New South Wales, Australia, jointly advised by Alina Ostafe and Igor E. Shparlinski. Previously I graduated with a bachelor and master degree from Institut Teknologi Bandung, Indonesia, advised by Aleams Barra.
I am interested in various aspects of number theory and combinatorics. In particular, my PhD project studies arithmetic statistics of algebraic groups using techniques from analytic number theory. Click here for more information on my research and education.
My CV in pdf is available via this link. Here are the links to my Google Scholar, MathSciNet, ORCID, zbMath profiles. My Erdős number is 3.
Outside of research, I am also involved in several mathematical outreach activities. For example, I wrote the following “moefied” math books (more information here):
I am a local in Banjarmasin, South Kalimantan, Indonesia. I am a native in Bahasa Indonesia and Basa Banjar. Outside of mathematics, I have various hobbies, as seen in this homepage.
