Julie Granka

Julie has been a population geneticist at AncestryDNA since May 2013. Before that, Julie received her Ph.D. in Biology and M.S. in Statistics from Stanford University, where she studied genetic data from human populations and developed computational tools to answer questions about population history and evolution. She also spent time collecting and studying DNA using spit-collection tubes like the ones in an AncestryDNA kit. Julie likes to spend her non-computer time enjoying the outdoors – hiking, biking, running, swimming, camping, and picnicking. But if she’s inside, she’s baking, drawing, and painting.

Filtering DNA matches at AncestryDNA with Timber

Posted by Julie Granka on June 8, 2015 in DNA, Science

When someone takes an AncestryDNA test, we compare their DNA to the DNA of the hundreds of thousands of other test-takers in the AncestryDNA database.  We’re looking for “DNA matches” — people who share DNA with one another, and so might be relatives. The main idea behind identifying a DNA match is to look for Read More
