The research area of the Circuits and Systems group covers the theory and applications of signal processing, including high-level digital system design.


This link will direct you to some slide presentations which are used to introduce the group to starting MSc students.
The complexity of electronic circuits is ever increasing, and so is their design. Two drivers are (i) already phenomenal integration densities are still doubling every 18 months (Moore's law), and (ii) new advanced applications require integrated solutions with increased intelligence and immense processing power. The main goal in our research program is to provide a sound mathematical framework for synthesis and analysis problems in the complete trajectory from system application, algorithm design, mapping to a hardware architecture or embedded system, VLSI circuit design, and finally the design verification.

Machine learning in physical sciences

Machine learning (ML) is booming thanks to efforts promoted by Google. However, ML also has use in physical sciences. I start with a general overview of ML for supervised/unsupervised learning. Then I will focus on my applications of ML in array processing in seismology and ocean acoustics. This will include source localization using neural networks or graph processing. Final example is using ML-based tomography to obtain high-resolution subsurface geophysical structure in Long Beach, CA, from seismic noise recorded on a 5200-element array. This method exploits the dense sampling obtained by ambient noise processing on large arrays by learning a dictionary of local, or small-scale, geophysical features directly from the data.
