Efrem Lim is a virologist who studies the human virome in health and disease. The virome is the diverse community of viruses harbored in and on humans, some of which cause disease while others are commensal. The Lim lab is particularly interested in understanding the interactions of the human virome in development and immunity. While most microbiome studies focus on bacteria, his interdisciplinary group sheds light on how viruses shape host-microbiome interactions.
The Lim lab integrates molecular virology and bioinformatics approaches in clinical cohorts to understand:
- how the virome impacts the trajectory of infant development
- the role of microbiome interactions in disease
- genomic epidemiology and public health surveillance
Their research is being used in precision medicine that personalizes the prevention and treatment of diseases to individuals.
In response to the COVID-19 pandemic, the Lim lab has led research efforts to understand and prevent SARS-CoV-2 transmission. This includes next-generation sequencing studies of SARS-CoV-2 to identify transmission patterns and functional studies to characterize virus mutations in clinical isolates.
