Ehsan Eqlimi

Ehsan Eqlimi currently works at WAVES research groupGhent University, Belgium. His work mainly focuses on developing the signal processing algorithms for brain functions and networks, through EEG, fNIRS, and fMRI. He also has interests in array signal processing including sparse representation,  blind source separation, and tensor factorization. 

Currently, he investigates how can the auditory attention/perception to speech in noise be monitored by single-trial EEG signal processing.

 He received B.Sc. and M.Sc. degrees in Bioelectrical Engineering from Sahand University of Technology and Tehran University of Medical Sciences, Iran in 2010 and 2013, respectively.

His Master thesis was on "Analysis of Brain Networks in functional MRI using graph theory for patients with MS" (see here).

 He has been a senior researcher since 2013 for 4 years at Tehran University. During this time, he focused on EEG source localization for motor intention decoding. He also has developed and published some novel algorithms for blind source separation based on the sparse component analysis (see here). 

He has the experience of working on "image processing and pattern recognition"  for the face and fingerprint recognition as an R&D engineer (2011-2016) in R&D departments of several reputable companies in Tehran, Iran.
