-        TBD
+        In recent years, the availability of big data has resulted in a growing 
+        number of users who are interested in interpreting the trends and 
+        anomalies for large datasets. This presents an imminent requirement of 
+        sophisticated data analysis tools that can provide qualitative 
+        information based on query answers on such datasets. In this talk, I 
+        will describe my current research on developing a principled framework 
+        for explaining query answers inspired by the theory of causality and 
+        intervention from the area of Artificial Intelligence. I will present 
+        our solutions to core challenges in this task such as obtaining concise 
+        descriptions of explanations, handling inherent dependencies of database
+        tuples, and achieving real-time efficiency in large explanation spaces. 
+        I will conclude the talk with several exciting future research 
+        directions spanning database theory and systems, algorithms, and user 
+        interactions with a graphical interface.

-        TBD
+        Sudeepa Roy is an Assistant Professor in Computer Science at Duke 
+        University since Fall 2015. She works in the area of databases and data 
+        management, with a focus on foundational aspects of big data analysis, 
+        which includes causality and explanations for big data, data provenance,
+        probabilistic databases, and applications of database techniques in 
+        other domains. Prior to Duke, she did a postdoc at the University of 
+        Washington, and obtained her Ph.D. from the University of Pennsylvania. 
+        She is a recipient of the NSF CAREER award and a Google PhD Fellowship.
