Personal profile

Research interests

I conduct my research within the Institute of Sensors, Signals and Systems in the School of Engineering and Physical Sciences. My current research activities focus on statistical signal and image processing, with a particular interest in Bayesian inverse problems with applications to remote sensing and biomedical imaging.

Biography

I was born in Toulouse, France, in 1987. I received the Eng. degree in electrical engineering from the ENSEEIHT, Toulouse, France, and the M.Sc. degree in Signal Processing from the National Polytechnic Institute of Toulouse, both in June 2010. I achieved my Ph.D. within the Signal and Communication Group of the IRIT Laboratory and received the Ph.D. degree from the INP Toulouse in 2013. Since 2014, I have been with the Heriot-Watt University, Edinburgh as post-doctoral researcher.
