Research Interests
My research interests relate to both systemic and data-specific aspects of Distributed, Large-Scale computing. Currently, I am focusing on algorithms for big-data management relative to: Data Quality, optimization of analytics/ML operators, graph analytics and uncertain data management. A full list of my publications can be found here.Author Impact
