Présentation

Hafiz TIOMOKO ALI was born in Cotonou, Benin. He received an engineering degree in Telecommunications from Institut des télécommunications d’Oran (Algérie) and a Research master in Advanced Wireless Systems from Ecole Normale Supérieure de Cachan (France) in 2015. He worked during his master thesis on "The performance analysis of spectral community detection algorithms on large random graphs" with Romain COUILLET in the chair LANEAS. He is working since October 2015 on his PHD topic "Random Matrix Theory and Large Dimensional graphs" under the supervision of Professor Romain COUILLET. He was visiting Professor Alfred Hero at the Electrical Engineering and Computer Science department of Michigan University from March 2017 to July 2017, working on statistical inference methods applied to biological data. His research interests are related to machine learning, graph theory, statistical inference and random matrix theory.
