Diptera researcher at the Lee Kong Chian Natural History Museum, National University of Singapore (LKCNHM, NUS) with an interest in acalyptrate flies (Sepsidae in particular) especially within the Oriental region.

I'm also a proponent of 'cyber taxonomy', and very interested in high-resolution, high-throughput digital bioimaging - especially for tiny arthropods. It is my belief that digital imaging is crucial for morphology and taxonomy to survive the coming years - especially since we are at the age of tackling 'open-ended' insect taxa.

Check out the biodiversity image-based database sites that I've created/helped start up:

  • Sepsidnet (https://sepsidnet.biodiversity.online/): a digital reference collection for the Sepsidae (ant-like scavenger flies) of the World, currently covering >85% of all known genera and >65% of all described species. This is the largest collection of sepsid types and species images made digitally available!
  • Biodiversity of Singapore (https://singapore.biodiversity.online/) - an ambitious national-level project that aims to curate all the biodiversity that can be found in Singapore and her surrounding waters, based on a series of ongoing biodiversity discovery projects (mostly focused on arthropods). We suspect there'd be about 50,000 - 100,000 species within Singapore - meaning that we've just scratched the surface at ~15,000 entries currently. Still, this comprises the largest collection of specimen images of Singaporean species!
  • Wallace's Specimens online (https://wallace.biodiversity.online/) - this stemmed from a postdoc project that I was in - here, my colleage Dr. Wan Faridah Wan Jusoh went around the major British natural history museums (e.g., NHML, Tring, Oxford) to search for the specimens that Wallace collected in Singapore (and around) during his time in the Malay Archipelago. When found, we would image the specimens to taxonomic-research level standards along with associated label information, thus 'digitally repatriating' the specimens back into the Wallace Specimens Online site. This is one of the most complete image databases of Wallace's specimens digitally available. Wan is now leading the project and making headway into other European institutions in our hunt for more Singaporean specimens to 'digitally repatriate'.

I obtained my PhD in Biology from the Meier lab in the Department of Biology, National University of Singapore (DBS, NUS) in 2014. I am currently serving as a museum officer, functioning as the curator of Diptera and Coleoptera (and some other smaller insect orders) at LKCNHM. I also teach a module on biodiversity and natural history at the University Scholars Programme (USP, NUS).
