Career Profile

I am Data Scientist and a Researcher passionate about Machine Learning, Social Computing, and Privacy. My prior work, among others, includes leveraging Machine Learning to accurately identify online hate speech and I have also conducted several large-scale studies on social networks using various NLP tools.

I have experience both with supervised and unsupervised learning (e.g., Scikit-Learn, Tensorflow, PyTorch) as well as various Natural Language Processing technologies and tools (e.g., BERT, NLTK).

In the past, I served as a Marie Skłodowska-Curie Fellow at University College London from where I received my Ph.D. and I was also a Research Assistant at Queen Mary University of London. I hold an M.Sc. in Information Security and a M.Eng. in Software Engineering.

Experience
