In this talk, I will explore our research on three computer systems of the future. First, we have built an Elastic OS for cloud data centers to help applications auto-scale their computational and memory needs. I present results that highlight the utility of joint distributed disaggregation of computation and memory. Second, drones are increasingly flying in airspace where they pose a danger to others, such as near airports, jails, forest fires, buildings, events, etc. We present a new approach for low cost detection of the presence of drones by leveraging passive RF signals. This work recently received an ACM SIGMOBILE Research Highlights Award. Third, in the ubiquitous computing world of IOT, context will be king. To understand how context influences the behavior of mobile groups of users, we have built a mobile app called OutWithFriendz. I present insights learned from studying how mobile users organize group events.
