Jian Cui

I am a 2nd-year Ph.D. student at Indiana University Bloomington, specializing in artificial intelligence and security. My research focuses on leveraging AI to enhance cyber threat intelligence, including security event detection from social media, information gathering from the dark web, and improving phishing and campaign detection on blockchain. Recently, with the rise of large language models (LLMs), my work has shifted toward addressing threats to AI systems and applications, such as chatbots, ensuring their resilience and secure deployment in real-world scenarios.
