*News*

I have been awarded an ERC consolidator grant for the next 5 years (2023-2028); see here for more details.  I will be looking for PhD students and postdocs; see here. 

I will give a few talks in the coming months, at the 

• Colloquia for the Mathematics Department at Universidad Carlos III de Madrid in Leganés, 13 February 2023. 

• One World Mathematics of INformation, Data, and Signals (1W-MINDS) Seminar, online, 16 February 2023. 

• Edinburgh Research Group in Optimization (ERGO seminars), 12 April 2023. 

My book on NMF is available online.  The Matlab code of the book is available on gitlab. 

*Past event*
The second workshop on Low-Rank Models and Applications took place in Mons, 15-16 September 2022, see here for more information (picture, slides of talks, etc.).
