Justin D. Marshall
My research interests center around the performance of bridges and buildings subjected to significant external environmental loads, primarily earthquakes and significant wind events. I have been involved in both analytical and experimental work to develop new devices and mechanisms to improve performance of structures subjected to dynamic loads. I have also been involved in post-event reconnaissance engineering assessment teams deployed after the Haiti Earthquake (January 2010), Christchurch, New Zealand Earthquake (February 2011) Hurricane Michael (October 2018), Tornadoes in East Central, AL (March 2019) and Hurricane Dorian (September 2019).
