Hi, I'm Dorris.

I'm interested in public health, GIS, data visualization and instructional design.


My profile picture.

Current Research Interests

Currently, I am a PhD Candidate in Geography at the University of Georgia with an emphasis on public health and GIS. I am interested in how we talk about health, how we map health, and how we visualize health. I combine geographic information systems(GIS), data science, visualization with public health methodology in better understand the relationships with health and various phenomena across physical and virtual spaces. In addition, I also combine public health and GIS models in order to create innovative mobile and web mapping apps for health interventions and health communication. I am also interested using instructional design to create a variety of GIS related educational materials for a variety of audiences.

Public Health

My dissertation research revolves around women veteran’s health issues in terms of access for female veterans and overall satisfaction with the Veteran’s Health Administration. I am also interested in health communication and ways we can improve disseminating evidence-based health information to the general public along with specific groups such as educators and community groups.


My research revolves around using GIS to assessing spatial accessibility to health care facilities for women veterans. Specifically, I am looking at how to integrate traditional data sources, such as patient satisfaction surveys, and non-traditional data sources, such as Google Reviews, into spatial accessibility modelling.

Data Visualization

I am interested in creating data visualizations that assist with health communication and advocacy for public health related issues. For my research, I will create an web mapping app designed for women veterans to better understand the accessibility of VA Health facilities, identifying health and wellness resources that would be beneficial for women veterans, and information on VA eligibility along with organizations that help women veterans.

Instructional Design

I have a background in instructional design and instructional technology and have created custom modules and educational materials to make learning R less intimidating for a variety of learners. The ID models that I am most familiar with is the ADDIE model and the Dick, Carey, and Carey model.

Other Interests


I do a bulk of my research in the R programming language. I also know HTML, JavaScript, and Python. Once upon a time, I knew C++ as well. My interest in instructional design stems from doing too many headdesks and facepalms when trying to figuring out a coding issue and pondering of ways of teaching coding in a fun and accessible way.


I like taking photos…what else can I say? I especially like taking nature pics and pics of my travels. Those actually go hand and hand come to think of it.


I am a registered yoga teacher(RYT 200) and teach alignment-based yoga classes and chair yoga classes. I currently run free classes for my fellow graduate students and I also teach a chair yoga class at the Athens Community Council of Aging. I am also on the Iyengar yoga Next Generation Outreach Committee which goal is to make Iyengar yoga more accessible to underserved and underrepresented communities.


I am currently a UGA Extension Office Master Gardener volunteer. I do the bulk of my volunteering at the UGA Extension Office at the Master Gardener Help Desk and I also do outreach events in the K-12 setting.

Network Analyst Troubleshooting Checklist

This past week, I was having a moment dealing with Network Analyst. I need to use this tool for my dissertation research, and for some odd reason, I thought it was going to be a piece of cake getting this part done. Oh how I was wrong. I felt like Rocky in Rocky III when he underestimated Clubber Lang and got knocked out. I used the OD Cost Matrix in order to find the least cost paths from my origins(population centroids derived from census tracts) to destinations(OBGYN providers) and vice-versa. ...Read More
