Jul 2017 - Jul 2020
Working as an analyst within an multi-university project headed by the Pacific Earthquake Engineering Research Center (PEER, UC Berkeley) and funded by the California Earthquake Authority (CEA). The PEER-CEA project aims to evaluate the benefits of seismic retrofitting of single family wood dwellings with known structural deficiencies. Major responsibilities revolve around the development of numerical models to simulate the seismic behavior of existing and retrofitted homes (backed by experimental testing) while collaborating with other teams in order to produce viable results from seismic hazard to eventual seismic loss estimates.
