I graduated with a Ph.D. degree in Computer Science from the University of Pittsburgh (Pitt) in 2009. I was co-advised by Dr. José Carlos Brustoloni and Dr. Adam J. Lee. The members of my thesis committee were Dr. Liz Marai and Dr. James B.D. Joshi.

My main research interests when working at Pitt were in several areas related to Computer and Network Security, namely:

• Usable security (HCISec)
• Botnet detection
• Usage Controls 

• Using Reinforcement to Strengthen Users' Secure Behaviors
