Ph.D. Students Yanif Ahmad and Anna Ritz Receive IBM and NSF Graduate Fellowships

Computer Science Ph.D. students Yanif Ahmad and Anna Ritz recently received fellowships from IBM’s Ph.D. Fellowship Awards Program and the National Science Foundation’s Graduate Research Fellowship Program, respectively, two prestigious and highly competitive fellowship programs.

Yanif’s research spans data stream query processing and optimization, and investigates how to augment processing with data models capturing the time-varying nature of attributes, to efficiently process queries. This continuously changing, time-dependent data naturally occurs in many stream applications, especially geospatial and financial applications. The models are an approximation of the raw data, requiring techniques to manage errors and their ...
