About Me

I am currently a Research Staff Member in the Science, Systems, and Sustainment Division (S3D) at the Institute for Defense Analyses. At IDA, I use qualitative and quantitative research methods to assess technologies and systems used by government sponsored organizations.

I received my doctoral degree in computer science from North Carolina State University (NCSU). At NCSU, I was a member of the Wolfpack Security and Privacy Research Lab, where my broader research interests included usable security and secret management. I was also a Graduate Student Measurement Science and Engineering Fellow at the National Institute of Standards and Technology (NIST). At NIST, I worked on projects analyzing cybersecurity definitions for non-experts, as well as the influence of observable characteristics within phishing emails.
