The nucleus is both the container for the genome and the definitive organelle of the eukaryotic cell. We blend modern genomics and systems biology approaches with the classic tools of molecular cell biology to explore the function and dynamic regulation of the genome in relation to its nuclear environment.
We focus on the dynamic interplay between the genome and the nuclear lamina, which is a protein meshwork that scaffolds heterochromatin and protects the genome. We are working to understand how the nuclear lamina is assembled and maintained, how it performs its essential functions, and how it breaks down in disease and aging.
Our mission is to make meaningful contributions to science while fostering an inclusive laboratory culture that values both individual growth and effective teamwork. We believe that making scientific discoveries requires the audacity to question existing knowledge and the confidence to explore the unknown.
“Success” for us means empowering each lab member to discover. We welcome, respect, and advocate for members across the spectra of race, gender, and socioeconomic class. We embrace cultural differences and recognize that a diversity of perspectives makes for a stronger, more creative team.
We explore how the nuclear lamina scaffolds chromatin organization and sustains nuclear integrity in both pluripotent and differentiating cells. We manipulate the lamina using genetic perturbations and acute degron depletion tools. We apply genomics assays and live-cell microscopy to probe the functions of the lamina.
We use metabolic labeling and dynamic proteomics to profile nuclear protein homeostasis. We discovered that the nuclear lamina is an extremely long-lived protein structure but undergoes turnover in some disease states and developmental contexts. We are working to understand lamina biogenesis, quality control, and maintenance over lifespan.
Hundreds of mutations to the lamina and lamina-associated proteins cause “laminopathy” syndromes. We apply deep mutational scanning and proteomic methods to dissect the consequences of disease mutations on lamina assembly, structure, and function in order to enable informed decisions about treatment of these devastating syndromes.
