He has been involved with research and education in high-performance intelligent systems, Data Science and Machine Learning Algorithms, Sensor Fusion, Data Mining, and Intelligent Systems. Since receiving his Ph.D. degree in 1974 from MSU, USA, he has directed over 65 Ph.D. students, 100 Master's students, and many undergraduate students who are now faculty at Major Universities worldwide or Scientists or Engineers at National Labs/Industries around the world. He has published more than 600 research papers, has authored/co- authored and edited 26 books. His h-index is 63 with over 19000 citations and is among the list of top 2% cited scholars of Stanford study this year.

His books are published by MIT Press, John Wiley and Sons, CRC Press, Prentice Hall, Springer Verlag, IEEE Computer Society Press, etc. One of his books titled "Introduction to Parallel Algorithms" has been translated into Chinese. During the last thirty years Dr. Iyengar has brought in over 65 million dollars for research and education. . In the recent he has received $2.25 Million (USD) funding from the United States Army Research Office to develop a Center of Excellence in Digital Forensics in collaboration with HBCU institutions. This is considered to be one of the biggest achievement his in whole FIU, many such grants are in the past. He has providing the students and faculty with a vision for active learning and collaboration at Jackson State University, Louisiana State University, Florida International University, and across the world. Dr. Iyengar's career is a distinguished one, marked by his incredible record of success in groundbreaking research, inspirational teaching and excellence in community service. It is his consistent drive to fight for and promote the minority and underrepresented groups which is his passion.

Through his national and international contributions, he has consistently provided opportunities for minority students and underrepresented groups to participate in his research endeavors, and to develop local, state, and national programs to promote minority and underrepresented groups in computer science and STEM education programs. He has developed enormously successful models and programs that have been replicated in universities around the world. Through NSF, he developed a comprehensive network of computer education, and coordinated computer science workshops and short courses which introduced computer science to over 5,000 minority students and assisted minority faculty in advancing educational concepts and research. In his most current initiatives in providing computer science advising and student tutors, he has been able to significantly increase retention rates at his University in STEM areas.

Dr. Iyengar has also provided outreach to industry and to a variety of groups in the local high school community. Industry affiliations have resulted in internships with multiple Fortune 500 companies for his students. Informally, as well as formally through his NSF sponsored Research Experience for Teachers, he has worked with local science teachers in high school and middle schools to open up many of his labs for weekend work and interaction with the students to participate with undergraduate students in areas such as computer hardware, cyber security and robotics. He has invited and sponsored the Girls Who Code organization to provide summer seminars for local high school women--a tremendous success in preparing and recruiting high school women for STEM careers.

His research has been funded by National Science Foundation (NSF), Defense Advanced Research Projects Agency (DARPA), Multi-University Research Initiative (MURI Program), Office of Naval Research (ONR), Department of Energy / Oak Ridge National Laboratory (DOE/ORNL), Naval Research Laboratory (NRL), National Aeronautics and Space Administration (NASA), US Army Research Office (URO), and various state agencies and companies. He has served on US National Science Foundation and National Institute of Health Panels to review proposals in various aspects of Computational Science and has been involved as an external evaluator (ABET-accreditation) for several Computer Science and Engineering.

Departments across the country and the world. Dr. Iyengar has also served as a research proposal evaluator for the National Academy.

Dr. Iyengar, a computer scientist of international repute, is a pioneer in the field and has made fundamental contributions in the areas of information processing for sensor fusion networks, robotics and high- performance algorithms, all relevant to critical event detection systems as seen in following:

Co-inventor of the Brooks-Iyengar algorithm for noise tolerant distributed control which bridges the gap between sensor fusion and Byzantine fault tolerance, providing an optimal solution to the fault-event disambiguation problem in sensor-networks (1996)

Co-inventor of a novel, paradigm shifting method for grid coverage of surveillance and target location in distributed sensor networks (2002)

Provided seminal work for automated analyses and interpretation of satellite imagery of the ocean and other unknown terrain (1994)

Co-invented the Cognitive Information Processing Shell, a complex event processing architecture and engine which recognizes and responds to complex patterns in mission critical, real-time applications (2010)

Solved an open problem in graph recognition, laying foundation for fast parallel computing for large scale data sets (1988)

The impact of his research contributions can be seen in places like Raytheon, Telecordia, Motorola, the United States Navy, DARPA agencies, etc.
