My work is primarily in applied or practical ethics, including the ethics of AI, the ethics of emerging technologies, and environmental ethics. Much of my work uses applied contexts as a tool for reflecting on "deeper" or more theoretical problems in philosophy and ethics or draws on those theoretical resources from various areas of philosophy to resolve practical puzzles.  
I've tried to answer questions such as:
  • How do we design effective oversight to address the ethical issues raised by machine learning and AI?  
  • How should autonomous vehicles be programmed to behave when causing harm is unavoidable? 
  • Is it unethical to attempt to create a conscious artificial intelligence? 
  • To which sorts of things do we have moral obligations (humans, animals, plants, robots)?  
  • Which sorts of things have a welfare or can be made better or worse off?  
  • What is the relationship between welfare and moral obligation?  
  • Are laws that prohibit practices like factory farming or animal experimentation legitimate?
My recent book, The Death of the Ethic of Life, is available from Oxford University Press and on Amazon.
