Biography

Trisalyn Nelson's research develops and uses spatial and spatial-temporal analyses to address applied questions in a wide range of fields from ecology to health. Currently, her research focuses on two areas: wildlife movement and active transportation. Her research team is developing new GIScience approaches to quantifying movement, particularly from wildlife telemetry data, and applying methods to better understand conservation strategies for grizzly bears. Most recently, Nelson has led the creation of www.BikeMaps.org, a web-map and App to gather volunteered geographic information on cycling collisions and near misses. Nelson's research team uses BikeMaps.org and other crowdsourced data to quantify and monitor patterns of urban cycling safety and ridership.

Nelson enjoys working collaboratively and has worked with over 100 co-authors on >110 publications. She has secured $13.2 million research dollars ($9.3 million jointly and $3.9 solely) and been the primary supervisor of 24 graduate students. She is particularly energized by working with industry partners to develop and solve applied research questions. She has partnered with software companies, mapping agencies, urban planning consultants, police departments, and insurance agencies. She also works with cities and national governments on issues ranging from safe cycling to forest management. 

Nelson was at the University of Victoria in Geography from 2005 to 2016. There she founded and directed the Spatial Pattern Analysis and Research (SPAR) Lab, was Director of the Geomatics Program, and held the Lansdowne Research Chair in Spatial Sciences.
