Dr. Arunee Thitithanyanont, originally a pediatric infectious diseases specialist, has been a faculty member at Mahidol University since 1997. Her research primarily focuses on emerging viral infections such as avian influenza H5N1 virus, examining the dynamics between viruses and the immune system. As the Director of the BSL-3 Core Facility, she leads critical studies on pathogens including SARS-CoV-2, working collaboratively with teams both in Thailand and internationally to enhance vaccine development, understand viral transmission, monitor variants, and develop new antiviral drugs.

Dr. Thitithanyanont is also the founder of the Virus-X pathogen discovery program, aimed at the prompt identification of viruses that could potentially cause pandemics. Through this initiative, she seeks to strengthen our readiness for future viral outbreaks by upgrading infrastructure and enhancing the training of specialized teams. Her work provides valuable virological insights and develops innovative diagnostic tools and treatments, contributing significantly to global health security.


Research interests:

Dr. Thitithanyanont initially focused on the virulence of the avian flu (H5N1) virus, uncovering that dendritic cells are highly susceptible to this pathogen, which plays a significant role in its aggressive behavior. Additionally, her studies have shown that H5N1 can transmit between cells faster than typical human influenza viruses, shedding light on its potent virulence.

Currently, her research interests concentrate on the development of platforms for managing emerging viruses. Her work includes creating advanced models for antiviral discovery and implementing high-throughput systems for vaccine evaluation. Additionally, she is deeply involved in pathogen discovery through initiatives like the Virus-X program, which aims to identify and characterize novel viruses with pandemic potential. These efforts are designed to enhance global preparedness and response strategies against viral threats, emphasizing rapid detection and effective management of emerging pathogens.
