Hello/你好! I am an Assistant Professor in Statistics at Georgia State University. I am also a faculty member of Brains & Behavior in its Neuroscience Institute and affiliated with the Center for Cosmic Ray Studies.
GeorgiaI was a postdoctoral scholar at McGill University jointly with the University of Waterloo, kindly sponsored by the Canadian Statistical Sciences Institute (CANSSI). I am also affiliated with Mila - Quebec AI Institute and the Health Data Science Lab.
