September 22, 2017 - the Second Seminar on Infrastructure Resilience

We successfully held the 2nd seminar on Infrastructure Resilience at Lehigh University. There were over 40 audiences, including professional engineers, administrators, graduate students, and undergraduate students. The seminar consisted of two sesions. The first session focused on simplified methods for resilience assessment to improve effectiveness on regional planning and risk mitigation. The second session presented quantitative methods with applications in different engineering disciplines to conduct resilience assessment and improve engineering design. Find photos here.
