Research Interests: Williams leads a comprehensive program studying HMPV, including its molecular epidemiology, receptor usage (RGD-binding integrins), and immune response impairment via PD-1 signaling. His work extends to collaborative studies on respiratory virus epidemiology in immunocompromised patients and vaccine efficacy in children.

Publications: His recent studies (2025–2024) span HMPV pathogenesis, influenza vaccine effectiveness, RSV prevention strategies, and immune response modulation in neonates and aged individuals. These articles highlight interdisciplinary approaches combining virology, immunology, and clinical epidemiology.
