Hi! I am Stelios and I enjoy working with algorithms that improve performance of large scale systems, exploring data science techniques that span the areas of distributed computing systems including Cloud & Internet of Things and applications of statistical learning algorithms for real time big data analytics.

My research directions are shaped around design and implementation of new tehcniques and adoption of existing trends for the current systems to become more efficient, interoperable, and reliable and to operate on massive data sets.

I am admission tutor for MSc in Data Science & MSc in Computer Science and a member of the Experimental Data Science & Birkbeck Institute for Data Analytics.

I am always looking for PhD students, so if you are interested to work in the area of distributed computing system drop me an email!
