About Me

I am an Assistant Professor (UK Lecturer) in the School of Informatics at the University of Edinburgh. I am a member of the Institute of Computing Systems Architecture where I am leading the Large-scale Computer Systems Group.

Before coming to Edinburgh, I was a research associate (2018 - 2020) at the Imperial College London working with Peter Pietzuch. I earned my PhD degree from Imperial College London under the supervision of Paolo Costa and Alexander L. Wolf. My PhD was supported by a Google Fellowship in Cloud Computing. During my PhD study, I was a research intern (2015, 2016) and a visiting researcher (2017) at Microsoft Research.

I am always looking for self-motivated PhD, MScR and Post-doc. Drop me an email with your CV if you are interested. I am a member of the supervisor teams in the CDT in NLP and the CDT in Biomedical AI. Check here for how to apply.
