Hao Xu is a research scientist at the Data Intensive Cyber Environment Center, University of North Carolina at Chapel Hill.
He has been working on improving the rule engine and the rule language, and the metadata catalog of the integrated Rule-Oriented
Data System (iRODS) since 2010. He developed pluggable rule engine architecture that allows interoperability between different
programming languages and the iRODS data management systems. He also developed QueryArrow, a semantically unified query and
update system that allows bidirectional integration of metadata from multiple heterogeneous data stores. His research interests
include theory of data management, automatic theorem proving, programming languages, distributed data systems, and formal
methods in software development. He has a B.E. in computer science and engineering and a B.S. minor in applied mathematics
from Beihang University and a Ph.D. in computer science from University of North Carolina at Chapel Hill. Terrell Russell
is serving as the Chief Technologist of the iRODS Consortium at the Renaissance Computing Institute (RENCI). Terrell works
on build and test for iRODS as well as code review, package management, documentation, and high-level architecture design.
He's interested in distributed systems, metadata, security, and open source software that accelerates science. Terrell holds
a B.S. in computer engineering, a B.S. in information technology and service organizations, an M.S. in computer networking
from North Carolina State University, and a Ph.D. in information science from the University of North Carolina at Chapel Hill.
Terrell has been working on iRODS since 2008. Jason Coposky is the Executive Director of the iRODS Consortium at the Renaissance
Computing Institute (RENCI). With over 20 years of industry experience, Jason has worked in a variety of areas including virtual
reality, EDA, visualization, and data management. Prior to RENCI, Jason was Technical Director for a startup where he developed
projection and distortion correction technologies. During his tenure at RENCI, he began a
