About Me
I am a Postdoctoral Associate in Statistics at the department of Statistical Science of Duke University. I currently live in Durham, a city in North Carolina, USA.
My complete curriculum vitae is available at this link. For more information about myself, you can also visit my GitHub and Google scholar profiles.
I am interested in Bayesian methods for the analysis of complex data, covering the theoretical, applicative, and computational aspects. I try to balance these three macro-areas in my research.
