Research Vision
My research vision is to empower users to intuitively find relevant information they need amidst
the fast-growing amount of information available on the Web and on Social Media.
I aim to achieve this goal by establishing new relationships amongst diverse information objects
thereby leading to recommendations users would otherwise not have found on their own.
Research Statement
My current research is focused on providing data analytics and AI solutions to alleviate
the acute information overload problem facing research and health institutions in dealing
with the fast-growing amount of diverse research objects and research related data on the
Web and on social media. Thereby uncovering insights and enhancing the value gained from
scholarly and health-related big data.
