Ed Williams has been active in genealogy since the 1980s, when state-of-the-art was a library that could send an image from microfilm directly to a networked printer. His fascination with DNA was cemented by a dinner with Francis Crick and James Watson when his university department sponsored a guest lecture. Yes; Ed is not a Millennial, or even an Xennial.
Ed has a B.S. in cell and molecular biology, and an M.S. in biochemistry...with which he didn't do as much as he'd planned, so he also ended up with an MBA. Both the science degrees are dated, so he braved being the oldest student in the class—probably on the campus—and in 2018 took post-grad courses and a lab in human genetics at the University of Houston.
His first DNA population/ancestry test was yDNA in 2002 for an academic study at the School of Biological Sciences, Washington State University. He's since tested with the original Genographic Project, Family Tree DNA (atDNA, yDNA, and mtDNA), AncestryDNA, 23andMe, MyHeritage and, after a 12-month wait, is now experimenting with his several VCF, BAM, and FASTQ files from a 30X Whole Genome Sequencing. He has two Guild-registered One-Name Studies, and admins or co-admins five FTDNA surname projects. Never having met a keyboard he didn't like (well, no full-sized keyboard, at least; his text messages are atrocious), he also has a sometimes-updated blog at CountingChromosomes.com.
