I am a software engineer at Google Cloud, leading the Policy Intelligence direction and spearheading efforts in this area. As a cofounder of IAM Recommender, I have successfully applied Machine Learning techniques to safely reduce excess privilege. Before joining Google, I earned my PhD from Northeastern University, where I conducted research under the guidance of Prof. Alan Mislove. My research focuses on distributed systems and networks, with a specific emphasis on harnessing the potential of local and cloud resources to enhance the security, privacy, and efficiency of emerging applications.
