Vita

Hi, I am Po-Han Hsu (許柏翰).

Currently, I am a Contracted Assistant Professor in the Department of Applied Mathematics at the National Sun Yat-Sen University (NSYSU, 國立中山大學). Prior to NSYSU, I was a Visiting Assistant Professor in the Department of Mathematical Science at the University of Cincinnati (UC). 

I graduated from National Tsing Hua University (國立清華大學) in 2010 with my Bachelor's degree (數學系10級); in 2012, I received my Master's degree from National Central University (國立中央大學) under the supervision of Professor Ching-Hsian Cheng (鄭經斅). Later, I served in the Royal Solute Company in the Army of Republic of China, Taiwan (中華民國陸軍禮砲連) for a year. After my military service, I joined Academia Sinica (中研院) as a research trainee in 2013. 

Then I went to Louisiana State University (LSU) to pursue my PhD degree in 2015. I learned Aye-Kuo stochastic integration from Professor Hui-Hsiung Kuo (郭輝雄) and stochastic partial differential equations from Professor P. Sundar. Finally, in May 2021, I received my PhD degree from LSU under the supervision of Professor P. Sundar. 

Here is my CV.

Research Interests

My research interests include stochastic analysis, probabilistic number theory, and partial differential equations.  Recently, I am interested in the study of invariant measures induced from stochastic partial differential equations such as the KPZ equation, the stochastic Burgers equations, and the stochastic Navier-Stokes equations; I am also interested in the applications of the theory of large deviations.

Aside from mathematics, I am interested in the philosophy of science, especially HPS, the sociology of scientific knowledge (SSK), and the history of madness. 

Recently, I collaborate with Hao-Lun Fu (傅皓倫), James T. Townsend, and Cheng-Ta Yang (楊政達) in a project regarding face cognition, which direct relates to the study of artificial intelligence.

Teaching


I have teaching experiences as an instructor at both LSU and UC. I am comfortable with both large (around 200) and small classes. Also, I am fine with teaching in virtual environment. Depending on the course content, I can switch my approach from traditional to flipped (classroom).


I have received certificate of teaching excellence, an evaluation of 3.89/4, and an evaluation of 4.93/5
