With over 25 years of field experience in international humanitarian relief, Peter Walker now leads a team of 30 academics and practitioners at the Feinstein International Center at Tufts University. His group conducts research to better understand the factors that lead to or exacerbate humanitarian crises, and how to effectively respond to them. Walker is actively involved at all levels: driving policy and international standards while also training aid workers for crisis response during his annual disaster simulation workshop at Tufts.
