## Biography

Dr. Emilie Hogan is a Computational Mathematics Scientist in the Computational Mathematics group at PNNL. She graduated from Rutgers University in May 2011 with a doctorate in Mathematics. Her PhD research was in creating an algorithm to prove global asymptotic stability of rational difference equations.

Her current research is in applications of discrete mathematics to cybersecurity, power grid, knowledge systems, and computational chemistry. In all of these research areas she is applying order theory and graph theory, to solve various real world problems.
