I am currently a Senior Professor at the Faculty of Languages and Linguistics, Universiti Malaya. My main areas of research include Varieties of English, in particular, Malaysian English, as well as language use in educational and in multilingual contexts. I also work on an endangered language, Melaka Portuguese, which I have digitally archived at the Endangered Languages Archive. As part of my interest in indigenous languages and culture, in 2019, I co-convened an exhibition on indigenous languages in Malaysia in conjunction with the International Year of Indigenous Languages. I also recently co-edited a book, Selected Research on Orang Asli Communities. My work and thoughts on endangered languages in general, and more specifically on Melaka Portuguese, have been featured in local and international media. I am a Fellow of the Academy of Sciences Malaysia and I was the 2013 Ian Gordon Fellow at the School of Linguistics and Applied Language Studies, Victoria University of Wellington. I am currently an Adjunct Professor at Mahidol University in Thailand.
