Welcome to the Columbia high-Speed and Millimeter-wave IC Lab!
The Columbia high-Speed and Millimeter-wave IC (CoSMIC) lab was founded in 2009 and explores a diverse set of research topics related to integrated circuits and systems. Our research spans a wide range of frequencies, from radio-frequencies to millimeter-wave, terahertz and optical frequencies, and a broad set of applications, including communications, imaging, and sensing. We are generally interested in any system that integrates a diverse set of (multi-)physical technologies, pushes the boundaries of complexity and performance, and is able to have a transformative impact on existing applications or pioneer new applications.
