Bader was hired as an assistant professor and Regents' Lecturer in the electrical and computer engineering department at the
University of New Mexico (UNM) in 1998. He remained at UNM until 2005, when he became the first faculty hire for Georgia Tech's CSE initiative. At Georgia Tech, his work emphasized hands-on experience and interdisciplinary research.
Richard M. Fujimoto was named the school's first chair, and Bader was later named the second chair of the school of CSE in July 2014. He served in that role until his term expired in June 2019. Bader was involved in a number of research partnerships between Georgia Tech and the public and private sectors. In November 2006,
Sony,
Toshiba, and
IBM selected Bader to direct the first
Center of Competence for the Cell Processor. In 2010, Bader was a lead investigator on the
Nvidia Echelon project, a $25 million
DARPA Award through the Ubiquitous High Performance Computing (UHPC) program. The four-year research collaboration with Nvidia covered work to develop new GPU technologies required to build the new class of exascale supercomputers. Bader and his lab partnered with Nvidia again in April 2019 to develop data analytics solutions for their GPUs. In 2011, Bader began working with the
Georgia Tech Research Institute on the
Proactive Discovery of Insider Threats Using Graph Analysis and Learning (PRODIGAL) project. On July 29, 2015, President
Barack Obama announced the National Strategic Computing Initiative (NSCI). Bader was invited by the White House on October 20–21, 2015, to serve as a panelist at the White House's National Strategic Computing Initiative (NSCI) Workshop. Following this, the White House's Office of Science and Technology Policy (OSTP) invited Bader to serve as a panelist at the NITRD High End Computing (HEC) Interagency Working Group (IWG) and Big Data Senior Steering Group (SSG) "Supercomputing and Big Data: From Collision to Convergence" Panel, at the 27th IEEE and ACM Supercomputing Conference (SC15) in Austin, Texas, on November 18, 2015. On July 29, 2016, Bader was an invited attendee to the White House's National Strategic Computing Initiative (NSCI) Anniversary Workshop. Bader also co-founded the Graph500 List in 2015 for benchmarking "Big Data" computing platforms. Bader was elected as an
IEEE Fellow in 2009. and later served as an Associate Editor-in-Chief of the Journal of Parallel and Distributed Computing (JPDC). Bader has been an associate editor of IEEE Transactions on Parallel and Distributed Systems, IEEE DSOnline, Parallel Computing, and the ACM Journal of Experimental Algorithmics, and has published over 400 articles in
peer reviewed journals and conferences. He subsequently served as Editor-in-Chief of ACM Transactions on Parallel Computing from 2018 to 2025. In July 2019, Bader joined the
New Jersey Institute of Technology as a Distinguished Professor in the Ying Wu College of Computing and was named the first director of the school's new Institute for Data Science. The institute is home to research centers in
AI,
big data,
medical informatics, and
cybersecurity at NJIT and conducts both basic and applied research. The
National Institutes of Health (NIH) has appointed Bader as a member of the National Heart, Lung and Blood Advisory Council (NHLBAC).
First Linux supercomputer Bader is credited with the development of the first
Linux supercomputer using commodity parts. In 1998, while at the University of New Mexico, Bader sought to build a supercomputer running Linux using consumer off-the-shelf parts and a high-speed low-latency interconnection network. The prototype utilized an Alta Technologies "AltaCluster" of eight dual, 333 MHz, Intel Pentium II computers running a modified Linux kernel. Bader ported a significant amount of software to provide Linux support for necessary components as well as code from members of the National Computational Science Alliance (NCSA) to ensure interoperability, as none of it had been run on Linux previously. Using the successful prototype design, he led the development of Roadrunner, the first Linux supercomputer for open use by the national science and engineering community via the National Science Foundation's National Technology Grid. Roadrunner was put into production use in April 1999. At the time of its deployment, it was considered one of the 100 fastest supercomputers in the world. Though Linux-based clusters using consumer-grade parts, such as
Beowulf, existed prior to the development of Bader's prototype and Roadrunner, they lacked the scalability, bandwidth, and parallel computing capabilities to be considered "true" supercomputers.
Steve Wallach, a
National Academy of Engineering (NAE) member and
Seymour Cray Computer Engineering Award recipient, remarked that Bader's technical contributions and leadership are "one of the most significant technical foundations of HPC." The
Computer History Museum recognizes Bader on its Timeline of Computer History for developing the first Linux supercomputer in 1998. "Within a decade this design became the predominant architecture for all major supercomputers in the world." ==Awards and recognitions==
