Abstract
First Person is a series of interviews with the first authors of a selection of papers published in Biology Open, helping researchers promote themselves alongside their papers. Matthew Penaso-Stinson and Summer Paulson are co-first authors on ‘ Macrophages migrate persistently and directionally upon entering 2D confinement in the presence of extracellular matrix’, published in BiO. Matthew and Summer conducted the research described in this article as PhD students in Dr Jeremy Rotty's lab at Uniformed Services University of the Health Sciences, Bethesda. Matthew is now a postdoc in the lab of Dr Martin Meier-Schellersheim at National Institutes of Health (NIH), Bethesda, investigating how binding of distinct extracellular matrix fibers determines macrophage directional migration and inflammatory responses. Summer is a recent PhD graduate interested in articulating the interaction between the microenvironment and intracellular signaling that drives microglial function.
