Aaron Doss, Andre Duong, and Jeremiah Viernes, 2025 Showcase
Visualizing Mass Killings in the United States from 2006 to 2025: We analyzed data from mass killing incidents in the United States from 2006 to 2025. Using the “Mass Killings in America, 2006 – present” dataset, we wanted to figure out how/if mass killing patterns in the United States have changed from 2006 to 2025 in terms of frequency, geography, and incident characteristics.
Aaron Doss: “I am pursuing a B.S. in Information Science and Data Analytics at San Jose State University. I have hands-on experience in public service and political data work, including managing the mayor’s office CRM for the City of San Jose, creating geospatial maps for a local political campaign, and supporting data and compliance projects for Loudoun County. Outside of work and school, I enjoy pickup basketball and am a devoted Golden State Warriors fan.”
Andre Duong: “I’m a Senior Year student at San Jose State University studying Data Analytics and Information Science. I love working with data to find trends and meaning behind the numbers to help inform others. I also do projects in 3D modeling, and I am minoring in digital media art. I hope to be able to use my knowledge I gained from the program and apply it to the real world in real jobs and internships.”
