I am a lecturer in the mathematics department at a large regional university in Thailand with broad research interests in geometry and topology. Despite heavy teaching duties, I recognize that an academic pursuit demands engagement with research at the forefront of the fields, especially early in my career. Attending the Forum would give me an invaluable opportunity to be inspired by role models, such as Professor Nigel Hitchin, a towering figure in geometry. By connecting with a cohort of young, enthusiastic mathematicians and scientists, I would also expand my expertise and learn from a more extensive academic community, fostering future potential collaborations.
To deliver wider impact, my classroom serves as a platform where I can share mathematical insights and experiences with students, especially those I would gain from the Forum. Letting them know of possibilities ahead of their academic journeys, I believe that it would shape how they view and, ultimately, build a stronger Thai mathematical society.

I am broadly interested in geometry and topology of surfaces. One of my current research problems is to give an asymptotic description of the distribution of zeros for iterates of differential operators in various settings. In a recent work, together with my collaborators R. Bøgvad, B. Shapiro, and G. Tahar, we show the following:
Pólya's classical “shire theorem” (1922) states that the zeros of the successive derivatives of a meromorphic function on the complex plane limit onto the edges of the Voronoi diagram determined by the poles of this function. We prove a generalization and a refinement for translation surfaces. On a compact Riemann surface whose flat translation structure is given by a meromorphic 1-form, we describe the geometric and measure-theoretic asymptotic distribution of the zeros of a meromorphic function under iterations of a linear differential operator defined by the differential. The accumulation set of these zeros coincides with the union of the edges of a generalized Voronoi diagram defined by the meromorphic function and the singular flat metric.
