Now based in Amsterdam, I've lived in San Francisco, Los Angeles, and New York, and I've reported from Madagascar, Tanzania, Madrid, Paris, London, Amsterdam, Vancouver, Chicago, Israel, Italy, Raratonga, Ecuador, Idaho, Nebraska, Indiana, NY, LA, DC, Yosemite National Park, all the other places marked on this map (which is better viewed on desktop), and more.   

I mostly cover issues related to science, technology, and the environment, and their intersections. I've also written features on criminal justice, education, mental health, medical science, early childhood development, and more.  

I have edited longform features for national consumer magazines including finalists for awards from the American Society of Magazine Editors and winners of Independent Press Awards. 

I also ghost-write op-eds, and write, ghost-write, and edit white papers, annual reports, RFPs, grant proposals and more, for research centers, multilateral organizations, government agencies, and others (when it doesn't present a conflict of interest with my journalism work).
