Welcome to my academic web page.

I am an associate professor in Mathematics at the department of Mathematics, faculty of Science, Khon Kaen University. I am interested in iterative methods for solving convex and nonconvex optimizations and applications in machine learning and image processing. I received my PhD in Mathematics from Naresuan University in 2017. At Naresuan University, I was advised by Professor Narin Petrot under the PhD student fellowship program of the Thailand Research Fund through the Royal Golden Jubilee PhD Program. I became a lecturer at Khon Kaen University in 2017.
