Matt combines mathematical modeling, human stem cell genome-editing, and fluorescence microscopy to study how actin produces force to function in cellular membrane trafficking processes.

He currently has two projects:

1) Understand the relationship between actin cytoskeletal architecture and mechanical function at sites of mammalian clathrin-mediated endocytosis by integrating agent-based mathematical modeling with cryo-electron tomography in collaboration with labmate Daniel Serwas; and

2) Understand how SARS-CoV-2 nonstructural proteins manipulate cellular organelle and membrane trafficking processes to make double-membrane genomic replication compartments, in collaboration with members of the Drubin/Barnes, Hurley, Betzig and Upadhyayula labs (and soon others)
