About

My name is Sakhar Alkhereyf  صخر الخريّف (pronounced /sˁaxar ʔlxərajəf/). My first name “Sakhar” means “rock” in Arabic.

I am currently a doctoral student (“ABD“) in the Department of Computer Science at Columbia University, working under Dr. Owen Rambow and specialized in Natural Language Processing (NLP). My research interests include document classification, social network analysis, and Arabic Dialects NLP. Specifically, I am interested in social network based methods for text classification. Currently, I am working on email classification using the underlying social network information.

I started my studies at Columbia University in 2014 as a student in the MS/PhD track.  I received a Master of Science (MS) in 2016 and a Master of Philosophy (MPhil) in 2018 both in Computer Science. Prior to Columbia, I was a research assistant at KACST in Riyadh, Saudi Arabia where I worked on various research projects in NLP and High Performance Computing (HPC).  I got my Bachelor’s degree in Computer Science from King Saud University in Riyadh, Saudi Arabia in 2010.
