Rick Stevens is Associate Laboratory Director for Computing, Environment and Life Sciences (CELS). He oversees a research program that connects computing to several areas of inquiry, and heads Argonne’s research initiatives for both exascale computing and computational biology.

Michael Papka is a data visualization expert whose current research interests involve the management, processing and analysis of scientific data. He is director of the Argonne Leadership Computing Facility, which houses an IBM Blue Gene/Q supercomputer.

Devin S. Hodge is the Chief Operations Officer (COO) for Argonne National Laboratory’s Computing, Environment, and Life Sciences (CELS) directorate. 

As the COO, Hodge leads both long- and short-range strategic and tactical operations for CELS and is responsible for the development, implementation, and management of efficient, cost-effective, and high quality operational and administrative support activities for the directorate. He has more than two decades of leadership experience, and he is committed to supporting Argonne’s important mission.

Dionysios Antonopoulos is a microbiologist studying how communities of microorganisms live and thrive together in a variety of environments. Currently, he is particularly interested in understanding how microbial communities maintain their stability in different environments. As a result, his research team is actively involved in creating new approaches for minimizing the complexity of natural microbial communities so that they can be studied in the laboratory.

Dr. Ian Foster is the Director of Argonne’s Data Science and Learning Division, Argonne Senior Scientist and Distinguished Fellow and the Arthur Holly Compton Distinguished Service Professor of Computer Science at the University of Chicago.  He was the Director of Argonne’s Computation Institute from 2006 to 2016.  

Foster’s research contributions span high-performance computing, distributed systems, and data-driven discovery.  He has published hundreds of scientific papers and eight books on these and other topics.  Methods and software developed under his leadership underpin many large national and international cyberinfrastructures.

Salman Habib is the Director of Argonne’s Computational Science (CPS) Division and an Argonne Distinguished Fellow. Habib’s interests and contributions cover a broad span of research, ranging from quantum field theory and quantum information to the formation and evolution of cosmological structures. He also leads projects in the areas of algorithms and computational methods, high-performance computing, and advanced statistical methods and machine learning.

Cristina Negri is the Director of the Environmental Science (EVS) Division overseeing environmental research conducted by approximately 160 staff and collaborators. Her current interests are in leading the development and execution of the Division’s strategic programmatic direction inclusive of a diverse research portfolio in environmental sciences.

Valerie Taylor is the director of the Mathematics and Computer Science Division. Her research focuses on performance analysis and modeling of parallel, scientific applications.
