Matthew Welch

Matthew Welch is a Professor of Cell Biology at the University of California, Berkeley, in the Department of BIO. His research program focuses on understanding how microbial pathogens target the machinery of their host cells during infection, with the overall goals of revealing crucial mechanisms of infectious disease and uncovering fundamental cellular mechanisms of general biological importance. Welch's work explores how pathogens interact with host cell structures and pathways, including the actin cytoskeleton and membranes, to promote invasion, intracellular replication, and cell-cell spread. His research also includes efforts to develop drugs targeting the cytoskeleton of parasites, such as trypanosomes, which cause neglected diseases. Welch's research has led to several publications in prominent journals, including Molecular Biology of the Cell and Nature Communications.

Matthew D. Welch is a Professor of Molecular & Cell Biology at the University of California, Berkeley, with research interests in cell biology, cytoskeleton dynamics, membrane trafficking, and microbial pathogenesis. His work focuses on understanding the mechanisms of actin nucleation and polymerization, particularly in the context of intracellular pathogens. Welch's research explores how pathogens like Listeria monocytogenes and Mycobacterium marinum exploit host actin machinery for motility and intracellular movement. His studies also investigate the role of the Arp2/3 complex in actin-based processes, including neutrophil chemotaxis and ER-to-Golgi transport. Welch's contributions highlight the interplay between host cell machinery and microbial strategies in cytoskeletal interactions.
