The University of Michigan's computer networks research adopts a comprehensive, system-wide approach, spanning from mobile computing and wireless technologies to datacenter architectures and global Internet systems. On the front-end, our efforts concentrate on optimizing web interfaces and mobile applications to enhance speed and usability while strengthening service infrastructure for dependable content delivery. Our wireless research explores hardware-software integration through cognitive radio systems, dynamic network adaptation, spectrum analysis, protocol development, and mobile solutions. For data center innovation, we prioritize synergistic relationships between applications and networks, developing network-aware software designs and application-specific networking solutions using coflow techniques. Our operating systems and distributed systems research addresses emerging challenges across embedded devices, sensor arrays, cloud platforms, and large-scale web services. Modern operating systems now permeate everyday technology, governing everything from conventional computers and global cloud networks to smart devices and critical infrastructure like transportation and energy systems. Michigan's research initiatives employ cutting-edge methods—including deterministic replay, parallel execution strategies, data redundancy techniques, and application-infrastructure co-design—to improve computer systems, data centers, and web services in terms of security, efficiency, scalability, reliability, and operational simplicity.
