About me
I’m an Assistant Professor at Portland State University in the Department of Computer Science. My research expertise is in the areas of data management and privacy. Specifically, my research focuses on two data protection methods: policy-based approaches (e.g., Access Control) and privacy-preserving mechanisms (e.g., Differential Privacy). I also study the challenges of integrating them in modern data domains, such as Internet Of Things (IoT).
