Tenindra Abeywickrama

I'm a data scientist at Grab!

I completed my PhD on POI search algortithms for road network graphs at Monash University under Prof. Aamir Cheema. I was a postdoctoral fellow with the Grab-NUS AI Laboratory at the National University of Singapore and a Endeavour Australia Cheung Kong Research Fellow. I received my bachelors degrees (B.Eng and B.Sc) from the University of New South Wales.
