The goal of the research group is to determine the structure and elucidate the molecular mechanisms of normal and pathological funciton of disordered proteins - specifically we focus on liquid-liquid phase separation into membraneless organelles and protein aggregation.
Current work focuses on:
- RNA-binding proteins involved in ALS and frontotemporal dementias
- glutamine-rich protein phase separation in cytoplasmic and nuclear assemblies across eukaryotes
Recent and current funded projects include:
Finding the molecular switch of FUS protein self-assembly in neurodegeneration
The major goal of this project is to determine the structure of FUS along its assembly pathway in neurodegenerative disease.
Seeds of protein aggregation in inclusion body myositis
Center of Biomedical Research Excellence (COBRE) for Skeletal Health and Repair, Junior Investigator
The major goal of this pilot project is to develop a molecular picture of aggregation of hnRNP proteins in inclusion body myositis and myopathy
Structural characterization of soluble and neurotoxic aggregates of FUS
RI-IDeA/INBRE Research Proposal Development Project
The goal of this project is to develop the protocols for recombinant protein expression and purification of FUS, a human RNA binding protein that forms neuronal inclusions in ALS and frontotemporal dementia.
Protein Aggregation in Preeclampsia: New Mechanism for a Deadly Pregnancy Disease
DEANS Award 2015 EMERGING AREAS OF NEW SCIENCE, Brown University
The goals of this project are 1) to identify and quantify aggregated proteins in serum of patients with PE and 2) to evaluate the ability of these protein aggregates to cause features of PE in our “humanized” mouse model.
