BIO

Dr. Juliet Morrison is an Associate Research Scientist at the Center for Infection and Immunity at Columbia University’s Mailman School of Public Health, where she specializes in combining computational analysis with immunological and virological methods to address questions at the host-pathogen interface. She leads collaborative influenza research projects under a large NIH subcontract while conducting systems-level research pertaining to emerging and re-emerging pathogens. She has spent the last 14 years studying innate immune responses to viral pathogens such as dengue virus, rhinovirus, poliovirus, yellow fever virus and influenza virus. During her graduate studies at Columbia University, she discovered that a viral protease facilitated poliovirus and rhinovirus interferon resistance. During her postdoctoral training at Icahn School of Medicine at Mount Sinai, she discovered and characterized two novel and disparate mechanisms whereby the NS5 proteins of dengue virus and yellow fever virus inhibit interferon signaling to enhance viral replication and pathogenesis. At the University of Washington, Dr. Morrison showed that influenza disease severity correlates with host transcriptional signatures of increased cytokine production, and decreased coagulation and lipid metabolism signaling.

In recent projects, Dr. Morrison has employed tissue deconvolution algorithms and immunological tools to study the dynamics of lung immune cell populations in influenza virus infections, and spleen and liver immune cell populations in dengue virus infections. By blending computational and experimental methods, she was able to identify a novel macrophage population that may play a role in influenza recovery. She is now working to understand how this population impacts influenza outcomes, and how its functions are regulated.  Dr. Morrison’s research is designed to be rapidly translated into host-targeted influenza virus and flavivirus therapeutics.
