Computing today is pervasive. We carry it around in our pockets. We access massive data‐centers used by thousands of people at a time to perform tasks whose complexity is increasing at an exponential pace. Electrical engineering at Princeton covers this entire range in scale. We are creating the next generation of architectures, software, and networks required to meet the insatiable demand for computation. To enable the adoption of these systems in critical applications, we are developing paradigms for secure computing, from the hardware level and to networks. We are developing systems that overcome the immense challenges related to power consumption, availability and cost, reliability, verification, and design methodology. We are building, testing , and attempting to break systems, then build them again from the ground up to create secure, reliable, and high‐performance multi‐scale computing infrastructure.
