I'm a principal researcher at Amazon Alexa ML. My research interests lie in Deep Learning and Natural Language Understanding. Before joining Amazon I was a researcher in Microsoft Research Labs, KULeuven, and RDI Technologies. I received my PhD from the CS department at the University of Toronto working with Gerald Penn and Geoffrey Hinton.
HIRING: I'm building a new science team in Amazon Alexa ML and hiring candidates with strong experience in Natural Language Processing, Machine Learning, and Deep Learning over all levels (with MSc or PhD degree in NLP and/or relevant industry experience). If you are interested send your resume to: AbdelrahmanAlexaNLP@gmail.com
