Dolan Research Group

Quantitative Virology and Evolution Unit

The Quantitative Virology and Evolution Unit focuses on understanding the dynamic and heterogenous processes of RNA virus infection and evolution. We characterize virus evolution and host-virus interactions across spatial and temporal scales using experimental tools, including high-resolution sequencing and live-cell microscopy, along with computational phylogenetic and bioinformatic tools. Projects in the lab include single-cell and single-genome sequencing of within-host virus evolution and host responses, phylogenetic reconstruction and evolutionary biochemistry in emerging RNA viruses, and design and analysis of mutational and functional genetic screens.

Patrick T. Dolan, Ph.D., is an experimental virologist and computational biologist whose work focuses primarily on the evolution and host-virus interactions of positive-sense RNA viruses. In the fall of 2021, Patrick began as unit chief of the Quantitative Virology and Evolution Unit at NIAID in Bethesda, MD, where he will continue to study the forces that shape the long- and short-term evolution of RNA virus populations.

William is a visiting postdoctoral fellow in the Quantitative Virology and Evolution Unit led by Dr. Patrick Dolan. William’s research is focused on studying the evolutionary constraints of RNA virus evolution. He has adapted deep mutational scanning methods to scan for fitness effects of mutations in viral genomes. In his primary work, William has uncovered enterovirus A’s structural plasticity...

During my Master’s and Ph.D. training, I worked mainly with the molecular epidemiology of norovirus with samples collected from children and immunocompromised patients (2014-2021). During the COVID-19 pandemic, I worked in a multi-center collaboration to perform the evolutionary and epidemiological track of the SARS-CoV-2 variants in Goias, Brazil. In January 2022, I began my postdoctoral...

I investigate the evolution of flaviviruses, focusing on dengue and West Nile viruses. I combine computational approaches like ancestral reconstruction and protein modeling with experimental techniques such as deep mutational scanning and noninfectious reporter assays. I seek to identify how the structural proteins of these viruses navigated selection over the course of the recent decades and...

I am currently attending Georgetown University as a bioinformatics master’s student. I’m mainly interested in elucidating virus evolutionary dynamics through one-health approaches to support animal, human, and environmental health. As a postbaccalaureate IRTA fellow, I assist the QVEU in single-cell RNA-seq analyses that identify virus-host interactions and enterovirus replication and rescue...

Lauren is investigating the diversity and evolution of enterovirus A71 (EV-A71) T-cell epitopes throughout the natural history of the virus to assess the role that T-cell immune escape has played in its evolutionary trajectory. By advancing our understanding of the identity, evolutionary trajectory, and evolvability of EV-A71 T-cell epitopes, Lauren hopes to provide insights that will inform the...
