Flexible Photonic Architectures
This research area aims to explore the design space of flexible accelerator network architectures by leveraging reconfigurable wavelength selective switches and Dense Wavelength-Division Multiplexing (DWDM) transceivers. The proposed architecture is evaluated using network-level simulations and testbed experiments, and its performance is compared with state-of-the-art accelerator architectures. A key objective of our work to develop a flexible, photonic interconnect that enhances communication efficiency in AI/ML applications.

Michael Cullen Profiled by Columbia Engineering
PhD student Michael Cullen was recently the feature of an article by Columbia Engineering, where he described his work on MCM modules and how his PhD work has expanded his skills. “People think that PhD life is only about research,” he says. “In reality, you become a graphic designer, a software developer, a public speaker, a grant writer, and you travel for conferences, build connections, give lab tours, and mentor younger students.”
