Cassandra Willyard
I am a freelance science writer based in Brooklyn, New York. My career has taken me from the Colombian jungle to the wheat fields of North Dakota. I cover everything from ecology to epigenetics, but my favorite topic is infectious diseases. I can tell you how scientists are using salt to combat parasitic worms in Guyana and why circumcision makes a man less likely to catch HIV. Website.
