I am an Assistant Professor in the School of Interdisciplinary Informatics at the University of Nebraska Omaha. My research focuses on securing AI systems that act, remember, communicate, and operate in cyber environments. I work at the intersection of agentic AI security, adversarial machine learning, malware analysis, binary security, and autonomous red teaming.
Our group studies how modern AI systems fail under adversarial pressure, how those failures can be measured through reproducible benchmarks, and how robust defenses and autonomous security tools can be built for real-world cyber settings.
A unified research effort in agentic security and adversarial machine learning: discover attack surfaces, formalize threat models, build benchmarks, generate attacks, evaluate defenses, and automate red teaming.
Security analysis of agentic AI systems.
Building agentic systems that can support the vulnerability lifecycle.
Attacking, evaluating, and defending ML-based malware detectors and binary-analysis systems under realistic adversarial constraints.
Uses SHAP values to attribute CNN malware detections to PE regions, enabling fine-grained perturbation strategies and improved evasion effectiveness.
A code-cave and loader approach to hide adversarial perturbations across PE files while preserving malware functionality and improving evasion.
Evaluates misuse and defensive potential of generative AI tools, including security feature comparisons, privacy implications, and ethical risks.
Studies label-flip poisoning on ML-based malware detectors and develops practical hardening strategies for robust security models.
