Paulo Costa

Paulo Costa has applied his significant experience as a fighter pilot to a career specializing in the field of electronic warfare and flight safety, which in conjunction with his research on probabilistic reasoning has led to applications in cyber and transportation security, heterogeneous data fusion, and decision support systems in healthcare, defense, and other areas. These topics are at the core of his classroom activities at both graduate and undergraduate levels, as well as his research path. Costa leads the research of graduate-level students in understanding security objectives and verification protocols, bringing in the science of probabilistic reasoning and challenging PhD-level candidates to consider theory and methods for building computationally efficient software agents that reason, act, and learn in environments characterized by noisy and chaotic traffic.

Costa is a key researcher in the field of probabilistic ontologies and has developed innovative applications and extensions that aid in the fight against cyber-warfare. In addition to his Mason assignments as Chair of the Cyber Security Engineering Department and Director of the C5I Center, Dr. Costa is Vice President for Securing Automation and Supply Chain Security (cymanii.org). He is a former President and current elected member of the Board of Directors of the International Society of Information Fusion (isif.org), as well as an IEEE Senior Member (SM13).

Sai Sriram Uppada

? Hi, I’m Sai Sriram Uppada – a Data Analytics Engineering graduate, AWS Certified Data Engineer, and AI enthusiast who enjoys building end‑to‑end data, ML, and LLM‑powered systems that solve real problems in a scalable way.

I recently completed my Master’s in Data Analytics Engineering at George Mason University (GPA 3.85/4.0), where I focused on data engineering, machine learning, and LLM-based analytics. Over the past few years, through academic projects, research work, and internships, I’ve worked across the full data lifecycle: from ingestion and ETL to modeling, evaluation, and deployment for analytics and intelligent applications. I’m actively seeking full-time and internship opportunities as a Data Engineer, Data Analytics Engineer, or Data Analyst where I can contribute to data platforms, AI-driven products, and cloud-native solutions.
