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.
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.Quantitative Research Natural Language Processing Social Network Analysis Privacy Security
