Research Focus

Welcome to our research laboratory, where our central theme revolves around unraveling the mysteries of cell biological processes and the host's defense mechanisms in the context of viral infections. While our interests are diverse, we are particularly drawn to the captivating world of RNA viruses. Our dedicated team is committed to exploring the intricate interplay between viruses and the host cells they infect. By focusing on RNA viruses, though not exclusively, we aim to uncover the underlying molecular and cellular intricacies that govern the entire lifecycle of these viruses—from infection and replication to dissemination. Through our rigorous investigations, we aspire to contribute to the broader comprehension of viral pathogenesis. Our ultimate goal is to shed light on novel antiviral strategies and therapeutic interventions that could potentially revolutionize the field of virology.

Research Interest

Unraveling the Enigma of RNA Virus Persistence  

The laboratory is dedicated to the meticulous study of RNA viruses, tracing their journey marked by a ground-breaking concept: VIRAL PERSISTENCE. This revolutionary idea empowers viruses to seamlessly adapt to the ever-evolving host responses, perpetuating the dynamic struggle between virus and host. From historical references to the intricate puzzle of Long-COVID Syndrome, the evolutionary prowess displayed by viruses remains nothing short of extraordinary.

Our inquiry delves deep into the heart of this exploration, where understanding the unwavering resilience of RNA viruses—spanning across enteric, respiratory, and neurotropic—serves as the pivotal cornerstone for crafting effective strategies against relentless viral challenges. As the battle against emerging diseases rages on, the pursuit of deciphering the mysteries posed by these viruses becomes not just essential, but imperative. Within the confines of our laboratory, we embark on an unwavering quest to unveil the intricate mechanisms that viruses deftly employ to persist within their host environments.
