Alum Keeps Security Threats at Bay Working in the Caribbean


Heriberto Acosta-Maestre is a proud Shark, graduating from NSU’s College of Computing and Engineering in 2021 with a doctorate in Information Systems Security. Since 2009, he has worked in a variety of high-end technical and managerial roles at the U.S. Army National Guard in Puerto Rico, currently as a program manager, overseeing multiple technical projects. In 2023, shortly after earning his Ph.D., he became a Cybersecurity Research Fellow at the William J. Perry Center for Hemispheric Defense Studies in Washington, D.C.
“I pursued my Ph.D. at the NSU Davie Campus while living and working full-time in Puerto Rico,” Acosta-Maestre said. As part of the program, he completed his studies online and traveled to campus once a semester for required weekend seminars. “One of the key reasons I chose NSU was the flexibility of its hybrid program that allowed me to continue my professional career while earning my doctorate. NSU’s format made it possible to balance both effectively.”
Although working full-time while earning a degree can be challenging, Acosta-Maestre’s strong time management and support from his supervisors made it possible. “They were incredibly understanding and instrumental in helping me complete my studies while maintaining my professional responsibilities,” he said.
According to Acosta-Maestre, earning his NSU Ph.D. immediately positioned him as a recognized expert in the field, giving his opinions greater credibility. His advanced education created opportunities for him to speak at conferences and, most importantly, led to his current role as a Cybersecurity Research Fellow.
“The Ph.D. taught me how to work independently, analyze complex problems, communicate effectively with both executives and technical experts, and present ideas in a clear and structured manner,” he said. “Without the Ph.D., I would not have been considered for this role.”
Through Acosta-Maestre’s doctoral dissertation, he gained an understanding of behavioral factors that influence threat avoidance and a unique perspective when developing strategies to mitigate cybersecurity risks. “At the Perry Center, I integrate this knowledge into discussions on cyber defense, helping inform policies and training programs that improve cybersecurity awareness and resilience among government agencies and international partners.”
Acosta-Maestre said he enjoys his work at the Perry Center and plans to contribute to its mission, collaborating with United States hemispheric allies and advancing cybersecurity research and education.
“Looking ahead, I hope to further explore leadership opportunities in cybersecurity policy and strategy while continuing to mentor and educate the next generation of professionals in the field.”
