Postdoctoral Fellows

Tristan Goodbody

TristanGoodbodyTristan Goodbody was born in the wild, cow-wrangling city of Calgary, Alberta. He grew up an expat in Ecuador, Malaysia, and Scotland prior to his admission to the UBC Faculty of Forestry in 2010. His involvement in the co-op program there afforded him hands-on experience working in the forest industry with West Fraser Timber Ltd. in Chetwynd, BC, and in research based forestry operations with the Alex Fraser Research Forest in Williams Lake, BC. Tristan graduated with a BSc in Natural Resources Conservation in 2015 and decided that he was not yet prepared for the real world.

Tristan’s research with the IRSS will use drone-captured imagery and semi-global matching to predict residual timber volumes following selective harvesting, to gauge stand regeneration success, and to map the extent and perimeter of local fires in the Alex Fraser Research Forest. In his spare time, Tristan can be found with his dog, Kyra, or anywhere there is good food.


Sean Kearney

Sean grew up in Durango – a small mountain town in southwest Colorado. He started his BA at Fort Lewis College, before transferring to Western Washington University to study International Business and Economics. After a stint volunteering on farms in Romania and Bulgaria, Sean gravitated toward farming and went on to complete an M.Sc. in International Agricultural Development at UC Davis. During his masters, Sean worked in rural Uganda coordinating farmer fields schools and soil fertility research trials related to diversifying smallholder vegetable production. In 2011, he moved back to Durango for a couple years to run a composting company and organic farm, before diving back into the academic scene to complete his PhD in Soil Science at UBC. His doctoral research used both field and landscape-scale approaches to measure ecosystem services from smallholder agriculture in El Salvador. After a circuitous path from ski-bum to heavy-equipment operator to farmer to scientist, Sean now has both feet firmly in the remote-sensing world, and is working as a post-doc with the Grizzly-PAW project to map human- and climate-induced impacts on ecosystems in western Alberta, with a focus on grizzly bear habitat.

When not at the computer or out doing field work, Sean still likes to get his hands dirty helping out at the UBC farm, climbing and skiing up/down mountains and wandering the forest with his dog and partner (they are two separate beings…Takaya and Susanna, respectively. Photo credit: Susanna).

Chen Shang

Chen Shang grew up in Beijing, China. When he was 18, he moved to Central China for his undergraduate degree in GIS and cartography at Wuhan University. Two years later, he started his journey in Canada through a joint program with University of Waterloo in Ontario, where he earned his second undergraduate degree in geomatics. Deeply impressed with the power of remote sensing, he stayed at Waterloo for his masters, working on a land cover change project using high spatial resolution imagery. Realizing the limitation of optical data, Chen moved to Kingston, Ontario, for his PhD at Queen’s University, where he got his hands dirty with LiDAR data for forestry applications.

Now as a Postdoctoral Fellow with IRSS, he is applying what he learned over the past years to Canada-wide land cover mapping with long time series of image composites. When Chen is not working in front of a computer, he enjoys reading, longboarding and the occasional flute playing.




Piotr Tompalski
PiotrTompalskiPiotr was born and raised in Poland and studied forestry at the University of Agriculture in Krakow. He spent 6 months on exchange at Wageningen University in the Netherlands where he became very interested in GIS and remote sensing, then deciding to write a master’s thesis at UAKrakow concerning applications of terrestrial laser scanning in forestry.

After obtaining his M.Sc. in forestry in 2008, Piotr began his PhD studies, expanding his research on the applications of various geotechnologies for forestry and nature conservation with a focus on vegetation growth in greatly disturbed areas. His research employs both airborne and terrestrial laser scanning data in addition to satellite imagery. He often uses OBIA tools to process his data, skills he acquired during his internship at Trimble Geospatial Division in Munich, Germany (2010). His research methods were influenced not only by the scientists at his home university but also by the researchers at Vienna University of Technology, where he spent a short time as a visiting PhD candidate.

Aside from his scientific work, Piotr enjoys teaching and loves photography and travelling; he often listens to jazz or progressive rock.
