Hello! I am a Privacy Engineer at Netflix. I have provided privacy and cybersecurity expertise on international data protection legislation, autonomous vehicles and other emerging technologies, and threat and risk modeling.  My research interests include creating methods for measuring privacy expectations, expanding contextual integrity theory, and developing privacy threat models. I was previously a Lead Privacy & Cybersecurity Scientist at MITRE (a federally funded R&D center acting in the public interest) and a staff researcher at Carnegie Mellon CyLab.

Research Efforts: 

MITRE PANOPTIC (TM) - A New Approach to Privacy Threat Modeling
Privacy risk models do not include data-driven threat components, which could increase their effectiveness. We are developing a privacy threat model based on a dataset of real-world privacy attack information. PANOPTIC is a robust, threat agent-agnostic taxonomy of actions that lead to privacy harms, with a partner model for the context of the threat. The threat model can be used  to describe privacy attacks and for privacy threat assessments, risk modeling, threat-informed defense, and red teaming.

Privacy Expectations & Norms Measurement
It is incredibly difficult to answer the question: what is appropriate data processing and use? We are creating a novel method for crowdsourcing privacy expectations, codifying them as privacy norms using Contextual Integrity Theory, and using them to develop privacy by design technical requirements and privacy policies for technologies that process personal information.

Please reach out if you are interested in collaborating or learning more about these efforts!
