Welcome to the
System Level Design Group

Everything we do is about understanding and harnessing computation and communication in technological and natural systems. We believe in thinking out-of-the-box and discovering the path not taken when discovering "new things".

We challenge the status quo by bringing science and engineering together. Specifically, we develop methods and tools to explore various angles in system design. Our current topics of interest include, but are not limited to, embedded, biological, and social applications. Our topics target computational platforms of the future and go beyond traditional silicon platforms.

We illustrate our vision by exploring embedded, biological, and social applications. Our research results are highly visible, widely cited, and consistently funded. Would you like to join us?

    Read the Abstract

    Abstract: During high school, I was fascinated by science. I used to read stories about Nobel Prize laureates and dream about their discoveries. Despite this, I became an engineer and, over the years, got to appreciate the power and transformative nature of computing in all human endeavors. In recent years, due to the cyber-physical systems (CPS) advent, I have found renewed interest and (somehow unexpected) opportunities to revisit some long forgotten topics in math and physics realizing that they can actually offer a much deeper understanding of CPS modeling and optimization. Truth being told, designing cyber-physical systems still feels more like an art rather than science but, in order to harness their huge potential, we need to reach beyond the established confines of computer systems design and (re)define a new science of CPS design. Starting from these overarching ideas, I discuss the theoretical foundations and practical implications of using a network approach to developing new mathematical models and tools needed to guide the CPS optimization ranging from hardware, all the way up to software, and (user-aware) application development. In other words, this talk is precisely about the subtle interplay between science and engineering and the joy of seeing things come full circle.
