Headshot small

Welcome to my website.

I’m a doctoral researcher based at the Oxford Internet Institute, exploring the ethical and political impact of data and AI on society, with specific research interests in AI ethics, the use of AI for social good, social media as a public sphere, and the use of algorithms to deal with online hate speech. My past research has included work on digital politics, big and open data, digital state surveillance, and the use of web archives in research.

I’m also a Research Associate at the Alan Turing Institute, where as part of the public policy programme I focus on translating insights from academia into effective policy frameworks for the ethical use of data science and AI by governments.

My other engagements include serving as the Convenor of the Turing’s Ethics Advisory Group, a member of the Institute’s Data Ethics Group, and a member of the Ethics Committee of Digital Catapult’s Machine Intelligence Garage, where I work with start-ups to develop action plans for ensuring the ethical use of machine learning technology. Finally, I appear regularly on Monocle 24’s morning show The Globalist to discuss politics and technology, and host AlgoRhythms, a weekly tech-focused podcast.

Less often than I’d like, I also write about food, sport, and films.

This website is a semi-regularly updated repository of my research, writing, project experience and other information. You can find me in other forms and formats on TwitterMedium, LinkedIn and Google Scholar.

The ethics of algorithms: key problems and solutions

Research on the ethics of algorithms has grown substantially over the past decade. This article builds on a review of the ethics of algorithms published in 2016 … to contribute to the debate on the identification and analysis of the ethical implications of algorithms, to provide an updated analysis of epistemic and normative concerns, and to offer actionable guidance for the governance of the design, development and deployment of algorithms.

A definition, benchmark and database of AI for social good initiatives

Initiatives relying on artificial intelligence (AI) to deliver socially beneficial outcomes—AI for social good (AI4SG)—are on the rise. However, existing attempts to understand and foster AI4SG initiatives have so far been limited by the lack of normative analyses and a shortage of empirical evidence. In this Perspective, we address these limitations by providing a definition of AI4SG and by advocating the use of the United Nations’ Sustainable Development Goals (SDGs) as a benchmark for tracing the scope and spread of AI4SG.

A new “perspective” paper by myself, Andreas Tsamados, Mariarosaria Taddeo and Luciano Floridi has recently been published in Nature: Machine Intelligence.

Introducing OxPod

I’m excited to announce OxPod, a new “conversational collective” of podcasts based here in Oxford. OxPod includes Nayana and my tech news podcast SkepTechs (formerly AlgoRhythms) as well as a number of other podcasts offering sharp insights about the big issues facing society.

OxPod can be found at www.oxpod.net, where you can also find a brand new page for SkepTechs which will host our episodes going forward.

A nervous onlooker’s guide to the 2020 presidential election, which will be fought in four dimensions

This election is not just about where — it’s also about whenWhen states report votes — and which votes are reported first— is likely to have a considerable impact on the perception of who is ahead at any given time.

I have a new blog post about the 2020 US presidential election now up on Medium.

Public Health in the Information Age: Recognizing the Infosphere as a Social Determinant of Health

Since 2016, social media companies and news providers have come under pressure to tackle the spread of political mis-and disinformation (MDI) online. However, despite evidence that online health MDI (on the web, on social media, and within mobile apps) also has negative real-world effects, there has been a lack of comparable action by either online service providers or state-sponsored public health bodies. We argue that this is problematic and seek to answer three questions: why has so little been done to control the flow of, and exposure to, health MDI online; how might more robust action be justified; and what specific, newly justified actions are needed to curb the flow of, and exposure to, online health MDI?

A new paper written by Jessica Morley, myself, Rosaria Taddeo and Luciano Floridi has now been published in the Journal of Medical Internet Research.

The Ethics of AI in Health Care: a Mapping Review

This article presents a mapping review of the literature concerning the ethics of artificial intelligence (AI) in health care. The goal of this review is to summarise current debates and identify open questions for future research. Our goal is to inform policymakers, regulators and developers of what they must consider if they are to enable health and care systems to capitalise on the dual advantage of ethical AI; maximising the opportunities to cut costs, improve care, and improve the efficiency of health and care systems, whilst proactively avoiding the potential harms.

I am a co-author on a new paper written with Jessica Morley, Caio Machado, Chris Burr, Indra Joshi, Rosaria Taddeo and Luciano Floridi, now published in Social Science and Medicine.

The Chinese approach to artificial intelligence: an analysis of policy, ethics, and regulation


In this article, we focus on the socio-political background and policy debates that are shaping China’s AI strategy. In particular, we analyse the main strategic areas in which China is investing in AI and the concurrent ethical debates that are delimiting its use. By focusing on the policy backdrop, we seek to provide a more comprehensive and critical understanding of China’s AI policy by bringing together debates and analyses of a wide array of policy documents.

Ethical guidelines for COVID-19 tracing apps

Here we set out 16 questions to assess whether — and to what extent — a contact-tracing app is ethically justifiable. These questions could assist governments, public-health agencies and providers [and] will also help watchdogs and others to scrutinize such technologies.

A comment piece by colleagues Jessica Morley, Rosaria Taddeo, Luciano Floridi and myself was recently published in Nature.
