Research Interests


I am interested in developing universal language tools, i.e. tools that would require little to no language-specific tuning. I am also interested in phylogenetics and typology in linguistics, and how this information can be used in the modeling of such tools. In crafting tools such as speech recognizers, morphological analyzers, and POS taggers, I have got a glimpse of how diverse and complex some languages of the world are.
