Kathleen Fernandes earned her Ph.D. in Educational Psychology from Stanford University and worked as a systems analyst designing military IT systems for the Department of Defense. Since retiring, she has been actively pursuing her Portuguese roots and became interested in genetic genealogy as a way to break through the brick walls she encountered in her research. She is particularly interested in tools and techniques for analyzing DNA data in endogamous populations. She has spoken at conferences sponsored by the Institute for Genetic Genealogy and is a frequent presenter on DNA topics to local genealogy groups in the southern California area.
