I'm a Senior Researcher at Rethink Priorities, where I work on the Worldview Investigations team conducting research aimed at helping philanthropists and policymakers navigate deep uncertainty about what matters most and where to direct resources. I hold a PhD in philosophy, with a focus in metaethics, the philosophy of mind, and the philosophy of probability.

My work sits at the intersection of philosophy and emerging technology. I have a particular interest in consciousness and moral status: what it means for a being to have subjective experiences, how we can reason rigorously under uncertainty about which systems are sentient, and what ethical obligations arise when the answer is unclear. As AI systems grow more sophisticated, these questions are becoming less speculative and more practically urgent — for researchers, developers, and institutions making consequential decisions today. Recently, I've been writing about how to interpret functionalism about consciousness and also what to make of LLM psychology.

I'm also a software developer. Before moving into full-time research, I served as lead web developer for The Humane League.

I live in New York City with my wife, Megan, and our dog Gigi.

I occassionaly write about AI and philosophy of mind on Substack.
