I am working on the theory of scalable data management . One of my goals is to extend the capabilities of modern data management systems in generic ways to allow them to support novel functionalities that seem hard at first. Examples of such functionalities are managing provenance, trust, explanations, and uncertain or inconsistent data. To support these functionalities, I am interested in understanding the the fundamental algebraic properties that allow algorithms to scale with the size of data by leveragi

For the hard questions, this work of line tries to find ways to change the objective in a way that qualitatively preserves the original motivation, yet installs those desirable algebraic properties (something we call ''algebraic cheating''). Our work has shown that approaches that leverage those properties and optimize for the overall end-to-end goal can work with less training data and achieve remarkable speed-ups .
