He was a Harvard Clinical Fellow (1996 – 2000) at the Cambridge Health Alliance in Cambridge, Massachusetts, where he completed his clinical psychology internship and neuropsychological post-doctoral fellowships, as well as engaged in research identifying early cognitive markers of HIV-related dementia.
