She is currently on leave from academia pursuing industrial applications of her research. Her interests are in computer networking; her work includes middleboxes, networked systems, measurement, cloud computing, and congestion control. Her recent research focuses on new opportunities and challenges arising from the deployment of middleboxes -- such as firewalls and proxies -- as services offered by clouds and ISPs. Justine received her PhD (2016) and MS (2012) from UC Berkeley, and her BS and BA (2010) from the University of Washington. She is a recipient of the David J. Sakrison prize, paper awards at USENIX NSDI and ACM SIGCOMM, and an NSF Graduate Research Fellowship. Most importantly, she is always on the lookout for a great cappuccino.
