AI-Driven Cybersecurity Researcher | Adversarial ML · LLM Security · Penetration Testing | IEEE Author · 220+ Citations

Profile Summary

I am a cybersecurity researcher and PhD candidate specializing in AI-driven threat detection, adversarial machine learning, and LLM security. My work sits at the intersection of offensive and defensive AI, I build and evaluate models that detect phishing, analyze malware, secure next-generation networks (5G/6G), and expose how large language models can be weaponized by threat actors. My research has been published in IEEE Access and presented at IEEE AIIoT, UEMCON, and CCWC conferences, accumulating 200+ citations and 155,000+ paper downloads. I have received multiple Best Presenter Awards and the Excellence in Research Award at Quinnipiac University (2025). I bring hands-on experience across the full AI security lifecycle: designing ML pipelines, building threat detection systems using Python, TensorFlow, and PyTorch, conducting penetration testing and vulnerability assessments, and deploying secure cloud architectures on AWS (AWS Certified Security-Specialty). I have also co-founded a university cybersecurity clinic, designed 10+ hands-on security labs, and led AI/ML research funded by NASA and NSF. I am available for cybersecurity research consulting, adversarial ML assessments, AI security audits, technical writing, and expert review of security systems and publications.
