Dr. Gary Liu is an Assistant Professor in the Department of Electrical and Computer Engineering at NJIT. Prior to that, he was a staff scientist at Science Data Group, Oak Ridge National Laboratory for 7 years. He received his Ph.D. in Computer Engineering from the University of New Mexico in 2008, M.S. and B.S., from Nanjing University of Posts and Telecom, China, in 2004 and 2001, respectively.
His research interests include high-performance computing, Big Data in data-intensive science, and high-speed networking. In particular, he has done extensive research on scalable data storage and analysis solutions on emerging architectures for HPC applications. His sole research products have been adopted by more than twenty HPC applications in fusion energy, high-energy physics, cancer research, quantum physics, turbine engine design, weather modeling, and etc., for production purposes. He was awarded outstanding graduate of the ECE Department at UNM. He was the distinguished employee of Computing and Computational Science Directorate at ORNL in 2012. He received R&D 100 award as a principle investigator in 2013 (with Rutgers University, Georgia Tech, and NCSU) for his contributions to adaptable I/O systems for Big Data applications. He has played leadership roles in several DOE projects.
