Chieu Hai Leong

I have completed my Ph.D. under the Singapore MIT Alliance programme, in the National University of Singapore.
My advisors were Lee Wee Sun and Leslie Pack Kaelbling.
I am now working at the DSO National Laboratories.

Some photo-events in reverse chronological order.

Southern ridges (continued): we continued the excursion into HortPark, where we found a wizard of Oz playground, [June 2008].

Southern ridges: we walked from Alexandra to Mount Faber, via Alexandra Arch and Henderson Waves. Took us 2 hours...., [June 2008].

Playing at the Jurong Central Park (snakes and ladders park), [May 2008].

At the Singapore Science Centre, [April 2008].

More photos soon (hopefully)....
