She is interested in finding ways to make GIS tools, maps, and data more accessible to everyday people. When she is not slouched over in an office chair squinting her eyes at the computer screen, she enjoys lifting weights and being outside looking at plants and bugs.

Tim Hitchins

Tim is a GIS developer with an obsession for interactive mapping, data analytics and everything in between. Since his early 20s, Tim has participated in various grassroots social justice, environmental and animal liberation causes. These days Tim spends his time working with community partners on projects that bridge the gap between analytics and activism. Tim graduated with an MS in Geography from Portland State University and is currently a GIS instructor at Portland Community College.

Isnardo Gandarilla

She is passionate about improving accessibility of services to under-served communities. Jess has lived in unincorporated Washington County for 12 years with two small, bored parrots who have taught her to abandon functional fixedness: just as a hammer is also a crowbar, a rolling pin and an entirely unironic objet d’art a beak is also a can-opener, a percussion instrument, and a tool for involuntary outpatient surgery.

Vincent “Walle” Brown

Walle Brown is a world travelling data analyst, strategy guru, organizational development specialist, and urban planner. He loves learning, synthesizing, and applying knowledge of disparate fields into harmonious projects. Originally from Georgia, Walle’s interest in mapping and data visualization spurred from researching the story-telling and synthesized explanations of the history of race-based segregation, discrimination, and systematic disenfranchisement. He is fascinated and inspired by the potential of mapping, visualization, and story-telling to catalyze the time and effort needed to understand power and place – especially between people groups. When not mapping, data mining, writing, or eating Walle is probably dancing, collaborating, or strategically planning on how to sustainably amplify community power in a meaningful, outcomes-driven, standpoint. .


Spencer Keller

Spencer, with a keen interest in digital art and music, was drawn to the field of GIS during his BS in Environmental Studies at Portland State University. Currently working towards an MS in Geography at Portland State University, he has discovered an interest in applied critical methodologies and qualitative mapping. This has led him to study (and pursue professionally) the accessibility and equity in public participatory GIS. In his work and studies Spencer is exploring spatial data sovereignty, decolonization, community engagement, and spatial justice.

Clement Uduk

Growing up in Portland’s Concordia neighborhood, Clement has experienced Portland’s life-cycle from quirky, off-beat hamlet in the Pacific Northwest to gentrified up-and-coming metropolis to one of the most interesting and complex cities in the U.S. as it pertains to social, racial and economic issues.

He received his bachelor’s in environmental science from the University of Portland and his graduate certificate in GIS from Portland State University. Clement is interested in water resource issues and mapping sociological phenomena like gentrification and transportation networks. He currently works for TrimbleMAPS as a GIS Analyst. When this guy isn’t mapping, you will hear him celebrating (or bemoaning) being a Trail Blazers fan, thinking of mapping projects, telling you why Meyers Leonard was the most controversial Blazer since 2001, or perfecting pozole verde recipes.

Lauren loves to collaborate with folks on community lead projects and hopes to continue to support her local and global community in any way she can.
