I am an assistant professor of Computer Science at Colorado School of Mines with a joint appointment at the National Renewable Energy Laboratory. I work at the intersection of databases, systems, information modeling, data science, the built environment and the Internet of Things. I am driven by building practical, efficient systems with open-source implementations that are proved through real-world deployments.

My research interests include (1) the design and implementation of high-performance databases, including graph and linked-data databases and timeseries databases; (2) IoT platforms that incorporate edge computing and cloud resources; (3) issues of digitization and data management in the built environment; (4) novel datasets or applications of data that motivate new data management techniques and abstractions.

Projects and Grants

• Brick Ontology: an open-source ontology and data model for data-driven smart building applications
• Mortar: a testbed and platform for “self-adapting” building analytics: write your code once and run it on 10s or 100s of buildings without changing a line of configuration or code
• Skewering the Silos (DE-EE0008681) is a DOE grant to continue development of Brick, in particular to expand its interoperability with existing metadata representations (Project Haystack, gbXML, Modelica, OpenBuildingControl/CDL and BuildingSync) and develop additional analytics and controls applications
• I am an active member of the ASHRAE Semantic Interoperability Working Group, working on the proposed 223P standard
