Looking around Doha, you get the feeling that the city is going to play a significant role in changing the composition of many fields in the near future. Having the chance to be a part of it is a great opportunity.”

Research Focus at QCRI

Dr. Da San Martino's main research interest is in the field of machine learning, applied to Natural Language Processing (NLP), including efficient and adaptive techniques for representing high dimensional data inside learning algorithms, such as kernel methods, with particular emphasis on designing fast learning algorithms for massive amounts of data and applications to NLP and biology domains.

The main focus of his research at QCRI is in designing and developing machine learning models of natural language for supporting advanced Arabic Language Technologies applications. A goal of his research includes devising techniques available through the Iyas framework, developed by the ALT group, in order to foster its use by researchers and industrial partners.

Previous Experience

Dr. Da San Martino received his PhD in Computer Science (CS) from the University of Bologna, Italy, and his MS and BS degrees in CS from the University of Pisa, Italy. From 2010 to 2014, he worked as a postdoctoral research fellow in the Department of Mathematics at the University of Padova, focusing on the design of efficient and adaptive representation for trees and graphs with kernel methods. In 2011, he was also a visiting researcher at the University of Wollongong, Australia.

He has published in top conferences and journals in the machine learning field. He is also a reviewer for the IEEE Transactions on Neural Networks journal and for several conferences.
