I am Dalkandura Arachchige Kalpa Shashika Silva Gunaratna and a PhD candidate at Kno.e.sis Center, Wright State University. My research interest lies mainly in fact summarization, data integration and alignment, semantic/cognitive computing, NLP, knowledge graphs, and Semantic Web technologies. I am also interested in data analytics and exploration of ML, IR, and AI techniques for intelligent data processing. I have also worked on Cloud and Distributed Computing in the recent past. I have done exciting internships at IBM Almaden (USA), NLM-NIH (USA), and Insight Center (Ireland) applying my research expertise.

I graduated (with First Class Honors) from UCSC of University of Colombo, Sri Lanka with the Bachelor of Science in Computer Science degree (BSCS). After my undergraduate studies, I worked in the industry as a software engineer in a reputed international company for one year and nine months.

I joined Kno.e.sis Center in 2010 summer and have been working with my advisors Prof. Amit P. Sheth and Prof. T. K. Prasad.

I successfully defended my PhD dissertation titled "Semantics-based Summarization of Entities in Knowledge Graphs" on April 19 2017 and joined Samsung Research America as a senior research engineer on June 19 2017.
