Callum Arnold

Callum Arnold is a Postdoctoral Scholar in the Department of Biology at Pennsylvania State University, affiliated with the Ferrari Laboratory. His research focuses on Infectious Disease Epidemiology and Respiratory Infections, with a particular emphasis on mathematical modeling to inform outbreak response strategies. His work spans vaccine efficacy, disease transmission dynamics, and public health policy implications.

Key research areas include:

• Evaluating measles susceptibility gaps and vaccination strategies in pediatric populations
• Optimizing SARS-CoV-2 interventions through latent class analysis and risk group modeling
• Assessing diagnostic uncertainty in early epidemic detection

Recent publications highlight contributions to understanding asymptomatic disease transmission, maternal immunization effects, and healthcare worker perspectives during pandemics. He is based at the Millennium Science Complex in University Park, PA.

Collaborations with clinical and public health institutions inform his interdisciplinary approach to addressing infectious disease challenges.
