I'm Umanga Bista , originally from Lamjung, Nepal and currently a PhD candidate at the Computational media lab, Australian National University .

My PhD supevisors are Prof. Lexing Xie , Dr. Aditya Menon , Dr Alexander Mathews and Dr. Lizhen Qu.

I am interested in applying Machine Learning to web and social media data. I also like to work with data streaming systems and fascinated by functional programming.

Current Research + Roles

PhD: Currently, I am working on Picturing everyday knowledge project. My proposed topic for phd is "Comparative Summarisation of Document Collections".

I am a Casual Research engineer in Computational Media lab, developing and maintaining 24x7 scalable data collection and preprocessing pipelines.
