I am an associate research scientist in the Computer Science Department at Yale University. My research focuses on building reliable and secure systems, spanning areas including distributed systems, programming languages, security, and privacy. I am currently working with Ruzica Piskac, Mahesh Balakrishnan, and Avi Silberschatz to enhance the reliability of large-scale distributed systems, by proposing efficient, accurate and deep auditing techniques. I am also working with Mariana Raykova on building a new anonymous reputation system.

I received my Ph.D. degree in 2015 from Yale University, under the guidance of Bryan Ford. My dissertation work focused on building a cloud-reliability auditing system (named Independence-as-a-Service or INDaaS) that can proactively detect deep, unexpected dependencies potentially causing cloud-scale correlated failures, which was published in OSDI'14.

I am currently on the academic job market.
