Nalleli's Bio

​My education at the University of Delaware paved my way to a career in public history. I was trained to scrutinize all matter of historical evidence from manuscripts and advertisements to photographs and objects. I also learned how to integrate my research into contemporary academic conversations in new ways.  Through opportunities like the Delaware Public Humanities Institute and hands-on work museum experience I developed a toolkit that has prepared me to share my love of history with diverse audiences.
