Beyond PCMag, I've written news stories and tutorials for a variety of other websites and publications, including CNET, ZDNet, TechRepublic, Macworld, Popular Science, Time, Fortune, US News & World Report, and AARP Magazine.
I've been working for PCMag since early 2016 writing tutorials, how-to pieces, and other articles on consumer technology.
