Dr. Meng's research areas involve studying the molecular mechanism of viral replication and pathogenesis and developing vaccines against viral diseases. He is particularly interested in emerging, re-emerging and zoonotic viral diseases.  Viruses currently being studied in Dr. Meng's lab include the human, swine and avian hepatitis E viruses, porcine reproductive and respiratory syndrome virus, porcine circoviruses, and SASR-associated coronaviruses.
