Joonha Park's Research interests & Publications

I am a postdoctoral research associate at the Department of Mathematics and Statistics at Boston University, under the supervision of professor Yves Atchade.  I received a Ph.D. in Statistics at the University of Michigan in June 2018 under the supervision of Professor Edward Ionides.

My recent works include 
1. The development of a spatiotemporal inference methodology for coupled stochastic dynamic models, such as spatiotemporal models addressing the transmission dynamics of infectious diseases https://arxiv.org/abs/1708.08543 
 The implementation of related methods, including the codes and the data, can be found at the Github repository https://github.com/joonhap/GIRF.git
 An R package SpatPomp is under development for wider accessibility to researchers in various applied fields.

2. A novel, general framework in Markov chain Monte Carlo with sequential proposals https://arxiv.org/abs/1907.06544
 The implementation of the algorithms discussed in this paper is available at https://github.com/joonhap/spMCMC.

I have research interests in Monte Carlo methods (SMC, MCMC), inference on high-dimensional partially observed Markov process (POMP) models (or hidden Markov models or state-space models), stochastic processes, high-dimensional data, the theory and applications of neural networks, machine learning, and epidemiological, ecological, environmental, and biological applications.
