Comparative syntax

I am interested in both macro- and micro-variation.  In the area of macro-variation, I have studied many languages from a comparative (macro-variation) perspective, such as Basque, French, and Chinese.  In the area of micro-variation, I have mainly concentrated on Chinese languages, comparing Mandarin, Cantonese and Taiwanese.  More recently, I have started studying Bantu languages, which can be considered to touch upon both macro- and micro-variation.
