Tharindu Kaluarachchi

PhD Candidate

Tharindu Kaluarachchi joined the Augmented Human Lab in October 2015 as an intern. In 2017 he received his B.Sc. honours degree in Electronic and Telecommunication Engineering from University of Moratuwa Sri Lanka. After that, he worked for two years as a research and development engineer at Cyrup (Pvt). Ltd. which is a start-up in Sri Lanka. There he has worked on developing solutions for local and international businesses using portable electronics, image processing, and machine learning.

Now he is conducting research as a Ph.D. student in the area of Human-Centered Machine Learning. He is interested in unsupervised learning, human-computer interaction, Artificial Intelligence in general and its real-world applications. He is hoping to use AI to help people learn things efficiently.

He likes to play badminton, TT, any card game, any board game, any role-playing game and he enjoys travelling, hiking, swimming, walking, singing, dancing, playing guitar and cajong
