Research

Interactive Information Retrieval

My work on supporting interactive information retrieval has focused on leveraging information visualization techniques to enable searchers to see information they need to make informed choices as they interactive explore among the search results and refine their queries.

Geovisual Analytics

I am interested in studying how visual analytics and information visualization methods can be applied to the interactive analysis of geo-temporal data, with a specific focus on high-dimensional data, movement data, and geospatial data that changes over time.

Innovation

I have an interest in studying the process of innovation, from an organizational perspective. The success of the initiation, adoption decision, and implement of an innovation depends on the people involved in the process; understanding the factors that influence innovation processes can help organizations to embrace innovation.

Sport Analytics

A significant amount of data is collected in relation to sport events, yet the tools for analyzing such data to discover insights is limited. My research in this domain focuses on the analysis of stakeholder engagement via social media, with a goal of supporting qualitative analysis of such data.
