I am from Singapore and started my Ph.D. in 2009. I have studied the ecology of freshwater crabs (notably an endemic species - Johora singaporensis) for over a year. I am joining this lab because I find amphibians to be very charismatic animals and good ecological indicators. My newfound interest and my dissertation topic will be the pH tolerance in amphibian species in Singapore and possibly in the region. I hope to finish my Ph.D by 2013.


My research on the effects of global warming and acid rain on amphibians is still ongoing. Amphibian species tested so far are Duttaphrynus melanostictus, Fejervarya cancrivora, Limnonectes blythii, Hylarana raniceps and Microhyla heymonsi. Increased temperature alone does not appear to have severe detrimental effects on survival for most species but pH 3.5 appear to be lethal for most. Synergistic interaction between low pH and increased temperature has been observed and appears to account for the majority of detrimental effects.


Prior to this Ph.D research, I was working in the Raffles Museum of Biodiversity Research. I have collaborated with National Parks Board on certain conservation projects. During my free time, I enjoy walking in the forest at night and photography.
