Andrew G. Klein

As a relatively new faculty member, there were several qualities that attracted me to be a part of the ECE department at WPI. The emphasis on interdisciplinary study and research, the opportunity to advise off-campus student projects with a global perspective, the chance to work directly with students through the IQP and MQP, and the focus that WPI places on both theory and practice all foster a unique and exciting environment. As the information age evolves, we are becoming more and more dependent on wireless communication networks to provide robust, ever-present connectivity to information. Advances in sensing, computing, and communication have enabled new ways in which information can be collected, processed, and disseminated wirelessly. While wireless networks are being deployed at a rapid pace, the growth and sustainability of heterogeneous wireless networks depends on further advancement of the theory and implementation of such networks. My research—and many of the courses I teach—attempt to address this problem. By learning the theory in lecture, and applying it to practice in the laboratory, students work with me to help tackle a range of problems relating to both the basic theory as well as practical design strategies for next-generation wireless communication networks. Beyond my work, I enjoy other interests including triathlons, mushroom hunting, bread baking, and rock 'n' roll.
