Education

I am currently a first-year doctoral student in the Computer Science department at
North Carolina State University in Raleigh, NC.  I completed my Bachelor's and Master's
degrees in Computer Science at the University of South Alabama in Mobile, AL in 2006
and 2008 respectively.

Research Interests

I recently joined the Cyber Defense Lab at NCSU to work under Dr. Ting Yu. I am currently exploring possible research directions the field of computer security, including phishing and insider attacks.  My previous research, at the University of South Alabama, focused primarily on combating email spam and adversarial attacks on statistical spam filters. I also worked briefly on developing machine learning based counterattack strategies against image-based adversarial attacks on spam filters.
