About Me

I’m currently a post doctoral fellow at the University of Warwick, UK. I graduated from the Cognitive and Brain Sciences PhD Program at the University of Kansas, USA, in 2017 and completed my undergraduate degree in Psychology at the National University of Singapore in 2011.

I was trained as a psycholinguist, although increasingly I think of myself as a cognitive scientist who uses techniques from network science to study cognitive structures, such as the mental lexicon and semantic memory. This figure broadly captures what my research is about.


1: Using network science methods to quantify the structure of cognitive networks and investigate how structure affects processing (bottom arrow)

  • How does the similarity structure of the mental lexicon (the part of long-term memory that stores phonological and orthographic representations) influence spoken and visual word recognition?
  • How does the structure of the phonological and semantic language network affect word learning and language acquisition?
  • How does the structure of the semantic language network affect semantic processing?

2: Using behavioral data to infer the structure of cognitive networks (top arrow)

  • Using fluency and association data from students and experts to infer their knowledge structure of a given domain (Small World of Psychology; Complex Forma Mentis)
  • Using phonological associations to study changes in the structure of the ageing phonological network and the bilingual phonological network
  • Survey responses to construct correlation (statistical) networks (eating disorder symptom network, experience of stuttering network)

3: Tying it altogether (middle arrow)

  • Computational work to draw explicit conceptual linkages between structure and process.
  • How can psychologists make use of the tools of network science to better understand how any cognitive process (e.g., lexical retrieval, word learning) operates within a given cognitive network?

OK, enough of the serious stuff. When I’m not doing research, I’m either out climbing, strumming my ukulele, or taking a really long nap. Sometimes I work on random things like making 3-d models of networks. Here is a shameless plug for my Shapeways shop.
