About Me

1 min. read

I am a Data Scientist, Research Associate, Software Developer. I love implementing interesting ideas and believe only by implementing them can I learn how good they are. My background is Information Retrieval (Computer Science). During my Ph.D., I studied location information, especially, social media users’ trail patterns. I love Python and most of the code I wrote for my Ph.D. projects is in Python. Sometimes I need the power from Hadoop/Spark to scale up my analysis to running on several hundreds cores.
