Who am I?

I’m a Philadelphia-based researcher, data scientist, and writer whose published work spans philosophy, psychology, bioethics, and public health. My peer-reviewed research has been published in prestigious journals ranging from Proceedings of the National Academy of Sciences to Hypatia: A Journal of Feminist Philosophy, and my writing for a broader audience has been published in Slate, The American Prospect, and The Philadelphia Inquirer.

I run a data science and research consultancy called Principled Research LLC, and am writing a book about mathematical deceptions and quantitative propaganda called B(u)y the Numbers. I also cover mathemagical rhetoric, argument-shaped bullshit, and science-adjacent propaganda on my science & Power Substack.

Minds, Machines, and Morals

How does the human nervous system produce moral judgment, action, inhibition, and regulation? Can—and should—we program computers, robots, and cars to do a better job at it than we do, or at least not do way worse?

The Rhetoric of Science [PDF]

How do scientists, corporations, and the media use language and argument to persuade people that certain claims are ‘scientific,’ and what exactly does that mean? How can we become more critical recipients and more effective communicators of scientific knowledge?
