Career Profile

I am a data scientist passionate about social computing, machine learning, and privacy. My prior work includes several large-scale studies on social networks and investigating the efficiency of machine learning tools for the identification of online hate speech. In the past, I served as a Marie Skłodowska-Curie Fellow at University College London and a Research Assistant at Queen Mary University of London.

Experience

Research Assistant

Nov 2019 - Aug 2020

Queen Mary University of London

Investigating the efficiency of machine learning tools for the identification of online hate speech. Specifically, studying how different methods, features, and datasets affect the performance of hate speech classifiers.

Marie Skłodowska-Curie Fellow

Aug 2016 - Jul 2019

University College London

Awarded a Horizon 2020 Marie Skłodowska-Curie Fellowship for the Privacy & Usability Innovative Training Network. My research focused on two aspects of direct-to-consumer genetic testing: a) identifying privacy and security limitations of the tools used for testing, storing, and sharing genomic data, and b) conducting large-scale studies on social platforms to characterize how far-right groups use genetic ancestry testing to promote racist ideologies.
