- Temporal GIS-modeling short-lived geographic phenomena
- GIS for education
- Volunteered geographic information
My background is in Geographic Information Systems & Science and I received my Master’s in Geography from the University of Iowa in May 2011. My area of research centered around modeling short-lived phenomena in geographic information systems and I also assisted in a research study to improve the efficiency of air quality monitoring efforts. I began volunteering at the Desert Botanical Garden in spring of 2012 and joined the Research Department as GIS-Database Technician in June 2012. I am in charge of collecting, organizing, and disseminating maps and other spatial data to staff and to the community. I am presently working with a group of volunteers to map the locations of all saguaros at the Garden. This information, and much more, will be published on a web map, accessible to the community, in February 2013. In addition to mapping plants and other features in the Garden, I am currently assisting the Research Department with the collection of survey-grade GPS data in Las Cienegas National Conservation Area and in the near future I will begin collaborating with the Education Department to create maps for learning activities. Having recently moved to the Phoenix area from Iowa, I have spent a good deal of time exploring the spectacular landscapes of the Southwest and learning how to keep my vegetable and herb garden thriving.
