About Me

_images/pic2.png

I recently moved to Heriot-Watt University, where I am Assistant Professor of Signal and Image Processing in the School of Engineering & Physical Sciences and at the Institute of Sensors, Signals, and Systems.

My research interests include optimization theory and algorithms, machine learning, data science, multi-modal signal processing, distributed algorithms, control theory, network science, and sensor networks.
