Welcome!


I am a computational social scientist working at the intersection of artificial intelligence and society, with a special focus on natural language processing (NLP). I read, write, and speak about employing NLP techniques for socially beneficial applications, as well as investigating how societal biases are reflected and reinforced through machine learned NLP models. I am also interested in ethical questions around machine learning from a global human rights perspective.

My prior research includes building scalable ways to identify and address large-scale societal issues such as racial disparities in policing, workplace incivility, gender bias and stereotypes, and abusive behavior online. To this end, I collaborate with researchers in Machine Learning and NLP, as well as social scientists and practitoners from Linguistics, Psychology, Education, and Journalism. I also co-organize the annual International workshop on Abusive Language Online (usually co-located with *ACL/EMNLP conferences).

I am currently a Research Scientist at Google, where I work on issues around Ethics and Fairness in Machine Learning. Prior to this, I was a postdoctoral researcher in the Computer Science department at Stanford University, where I worked with Prof. Dan Jurafsky and others at the Stanford NLP group, in an array of projects with a focus on applying Artificial Intelligence for Social Good. See my research page for more details.

    Invited panelist at the Ethics in NLP panel at the NAACL 2018 Industry track
    image
    "The panel consists of experts from both industry and academia, who focus their studies on ethical issues in NLP (and AI in general). They will discuss, among other topics, sources of biases that may creep into solutions, what we, as NLP practitioners, can do to raise awareness of such potential biases and reduce them, as well as societal impact of such unintended biases in deployed solutions."
