A central biological question is how natural organisms are so evolvable (capable of quickly
adapting to new environments). A key driver of evolvability is the widespread modularity of …

Many believe that an essential component for the discovery of the tremendous diversity in
natural organisms was the evolution of evolvability, whereby evolution speeds up its ability …

Wiring patterns of brain networks embody a trade-off between information transmission,
geometric constraints, and metabolic cost, all of which must be balanced to meet functional …

What makes living systems flexible so that they can react quickly and adapt easily to
changing environments? This question has not only engaged biologists for decades but is …

First and foremost are the Ph. D. students and post-docs who took a very active part in all the
experiments, analyses, and text of this manuscript. The present work is certainly more theirs …

With a continuing downscaling of the physical feature sizes, an increase in complexity and
the number of on-chip devices, and an increase in their heterogeneity, the traditional on-chip …

This dissertation builds toward a theory of the evolution of modularity, by investigating
specific techniques for promoting the evolution of different kinds of modularity, and using …

Communication has become a bottleneck for modern microprocessors and multi-core chips
because metal wires don't scale. The problem becomes worse as the number of …

Abstract As larger System-on-Chip (SoC) designs are attempted on Field Programmable
Gate Arrays (FPGAs), the need for a low cost and high performance Network-on-Chip (NoC) …
