Brief Biography
I am Sihyung Park (pronounced “See-Young”), a first-year Ph.D. student in the Department of Statistics at North Carolina State University. Prior to joining the Ph.D. program, I received a B.S. in Life Sciences (thesis advisor: Prof. Sung Wook Chi) and a B.Econ. in Statistics (double major) from Korea University. After that, I received an M.S. in Statistics from Seoul National University (advisor: Prof. Byeong Uk Park).
I am interested in applying machine learning methods in a socially and environmentally responsible way. I think most of the real-world issues can be solved using a well-crafted statistical model instead of a deep learning model. My current interests lie broadly in adaptive sequential decision-making, reinforcement learning, and tensor decomposition methods.

About the Blog
De Novo is a word frequently used in Biology, which means “of new”, or “from the beginning” in Latin. This blog is a journal written by a student who wants to make a living by studying and doing research. Contents are mostly about some interesting or important ideas I encountered while studying and doing research. This is my attempt to build up and organize new (and hopefully meaningful) knowledge.


Goni and Bori, my cockatiels. They love getting head scritches.
