Elvis Yang Huang （ཉི་མ་རྡོ་རྗེ）has four major strands of research. He is interested in language typology, contact linguistics, historical linguistics and language documentation. After a three-year fieldwork survey of the Southern Zhuang dialects (Tai-Kadai) in Guangxi Region, China, he wrote a concise reference grammar of Jingxi Zhuang. In recent years, he ventured into unraveling the process and outcome of the grammatical change induced by language contact. He used to focus on seven Zhuang dialects and four Chinese dialects in Guangxi Region, extrapolating a linguistic area of the Central Southern Guangxi Region which is advocated in most of my papers. His research interest covers language documentation (Minyag and nDrapa, Tibeto-Burman) in Western Sichuan, China.
