Student Qual/Thesis Committee Request (update as of 1/13/2026): I have already served on more than 10 student committees for Spring 2026. I am unable to take on any new student committees.

External Employment Opportunities (updated as of 02/01/2026). I do not currently hold any industry employment, consulting, or advisory appointments. I am open to future external opportunities on a part-time, advising, or visiting basis.

Lab Openings. We are warmly welcoming new members to the FORTIS Lab!

Hiring Ph.D. Students for Fall 2027 (likely 1-2 opening):
  • Ph.D. student hiring for 2026 Fall has finished.
  • Also check other labs with openings. Good luck!
  • Future Ph.D. students should be comparable to our 1st year Ph.D. students -- see FORTIS Lab.
Research Collaborators/Interns (Any Time, All Year Round):
  • We welcome both undergraduate and graduate interns from USC and other institutions.
  • We will provide GPUs/API keys for the project.
  • Preferred candidates are located in North America for time zone compatibility.
  • I do not hire in-person summer interns -- I am enjoying summer and working remotely :)
Application Process: To apply for either opportunities, complete the Application Form, email fortis@usc.edu after submitting the form, and review the FORTIS Lab website for more information before reaching out.

Research Interests: My research centers on building reliable, safe, and scalable AI systems, with a focus on understanding and mitigating failure modes in modern foundation models and agentic systems. I organize my work into two tightly connected tiers: (1) advancing the scientific foundations of safety and robustness in AI, and (2) translating these foundations into system-level evaluation frameworks and high-impact applications.

  1. Tier 1: Foundations of Reliable & Safe AI
    I study why and how modern AI systems fail under distribution shift, uncertainty, and strategic pressure, and develop methods to make their behavior more predictable and reliable. This tier integrates two complementary threads:
    • LLM & Agent Safety: Analyzing and mitigating failure modes in large language models and agentic systems, including hallucinations, jailbreaks, privacy leakage, model extraction, and multi-agent instability.
    • Robustness & Failure Detection: Developing algorithms and benchmarks for identifying abnormal or unreliable behavior, grounded in robustness, out-of-distribution generalization, and anomaly detection.
    Keywords: LLM Safety, Robustness, Agents, Hallucination Mitigation, Jailbreak Detection, OOD Generalization, Failure Analysis
  2. Tier 2: System-Level Evaluation & Scientific/Societal Impact
    I adopt a system-oriented perspective to evaluate, stress-test, and deploy reliable AI in realistic settings, and apply these methods to domains where failures carry high cost. This tier emphasizes two directions:
    • Evaluation & Benchmarking: Designing scalable evaluation frameworks, benchmarks, and workflows that probe model and agent behavior under realistic and adversarial conditions.
    • AI for Science & Society: Applying reliable foundation models to climate and weather forecasting, healthcare and biomedicine, and political or social decision-making.
    Keywords: Evaluation, Benchmarking, System-Level Analysis, AI for Science, Scientific Foundation Models, Climate & Weather Modeling, AI for Healthcare
