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.

Over one million DNA samples and many new scientific research findings

Ancestry science team gives two platform presentations on Friday, October 9th at human genetics conference ASHG With over one million customers who have submitted their DNA, AncestryDNA has the fastest-growing and one of the largest collections of human genetic data around the world.   That amount of DNA data powers the AncestryDNA science team to perform Read More

Filtering DNA matches at AncestryDNA with Timber

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

Recent University of Oxford study sheds light on estimating Great Britain ethnicity

Posted by Julie Granka on April 21, 2015 in DNA Tech, Science

This post was co-written with Peter Carbonetto, Ph.D., Computational Biologist at AncestryDNA For every AncestryDNA customer, we estimate the ethnic origins of their ancestors from their DNA sample—what we call a “genetic ethnicity estimate.” AncestryDNA customers can currently trace their ancestral origins to specific parts of the world, including 26 regions across Europe, Africa, Asia, Read More

AncestryDNA Scientists Achieve Advancement in Human Genome Reconstruction

Posted by Julie Granka on December 16, 2014 in DNA Tech, Science, Uncategorized

Passed down through the generations, fragments of the genomes of long-gone ancestors exist today in the genomes of their living descendants. Those fragments can actually be used to recover parts of those ancestors’ genomes – without having to resort to some more morbid techniques for obtaining their DNA.  That means a potentially easier way for Read More

The DNA matching research and development life cycle

Posted by Julie Granka on August 19, 2014 in DNA Tech, Science

Research into matching patterns of over a half-million AncestryDNA members translates into new DNA matching discoveries  Among over 500,000 AncestryDNA customers, more than 35 million 4th cousin relationships have been identified – a number that continues to grow rapidly at an exponential rate.  While that means millions of opportunities for personal discoveries by AncestryDNA members, Read More

AncestryDNA Regions by the Numbers

Posted by Julie Granka on March 25, 2014 in DNA Tech, Science

Since May of 2012, when we first released AncestryDNA, we’ve returned results to over a quarter of a million customers. Based on feedback that we have received, those 300,000 customers have learned a great deal about their family history – their deep ancestral origins and their genetic relatives. As it turns out, AncestryDNA has also Read More

Unraveling the Science Behind Ethnicity Estimation

Posted by Julie Granka on October 24, 2013 in DNA Tech, Science

A small tube of your saliva can reveal a lot about your family history hundreds and even thousands of years ago.  At AncestryDNA, we study the DNA in that saliva – using sophisticated science – to reveal your ethnic origins.  We recently announced an update to our ethnicity results which provides customers with a more Read More

AncestryDNA: part of the scientific community

Posted by Julie Granka on October 16, 2013 in DNA Tech, Science

Next week, the AncestryDNA science team will be flying across the country with a tube full of posters. Scientific posters, that is.  We’ll be presenting them at the annual American Society of Human Genetics conference (ASHG) in Boston.  This will mark AncestryDNA’s second year presenting our latest research at the largest worldwide conference in human Read More
