My first SAS voyage was 2017, and I am excited to sail again. I enjoy socializing, traveling, mentoring students, and the challenge of encountering cultures around the world. I grew up North Carolina, lived in many places during my pre- and graduate school years, and finally settled in Colorado in 2006. As an anthropological archaeologist, my research focuses on the application of geophysics approaches to the spatial organization of settlements, especially ancient cities. My recent projects include a study of city planning at Middle Bronze Age Kurd Qaburstan, Iraq, and Iron Age Tell es-Safi, Israel. I have been fortunate to conduct fieldwork in Turkey, Israel, Palestine, Syria, Iraq, and U.S.A.

I was raised in Kansas and studied at Baker University, returning to teach there in 2011. Wanting to be a Psychologist, I studied at The University of Georgia for my graduate degrees, and maintain a private practice in addition to my roles at Baker. I studied abroad at Harlaxton College in the U.K. and in Mexico. I was fortunate to grow up in a travel-loving family and travel has been one of my life’s greatest joys. In 2003, I spent a year tending bar in Edinburgh, Scotland; I’d made myself two promises; don’t fall in love, and take a break from being a therapist. Fortunately, I failed on both fronts, meeting my husband and using my therapeutic skills to cut patrons off, break up fights and soothe broken hearts. We have three children who will be joining us on the voyage.
