Description of Research Expertise

Our laboratory studies the signals that turn on and regulate the immune system during infections with common respiratory viruses, such as the influenza virus or the respiratory syncytial virus.

These viruses can cause or exacerbate chronic lung diseases, such as asthma, and can be fatal in some patients.

Our long-term goals are to better understand the factors that modulate virus pathogenesis and to harness this knowledge for the development of better vaccines and antiviral therapies.
