Eric HernandezPh.D., Northeastern University
Office hours: I am on sabbatical for AY 2017-2018.
Title: Associate Professor
Area(s) of Expertise:
My research aims at developing more accurate algorithms and cost-effective technologies to monitor and assess the integrity of complex infrastructure systems and reduce their risk of catastrophic collapse. My approach to this problem is as a probabilistic inverse problem.
