Graduate Students

Jeremy Arkin


Jeremy Arkin grew up in the suburbs outside of Chicago before moving to Boulder, Colorado where he received a bachelor’s degree in EBIO (Evolutionary Biology and Ecology) and Geography. Aside from normal coursework, his first professional experience in forestry was the completion of his honors thesis under the supervision of Dr. Thomas Veblen where he analyzed the upper montane tree regeneration following the 2002 Hayman Fire. After graduation he worked as a Forestry and GIS Technician for Boulder County Parks & Open Space as well Colorado Parks & Wildlife where he was able to gain insight on how to properly manage land in accordance with the very best methods and research available.

These experiences helped him to explore what kind of research he wanted to complete in graduate school as well as what kind of career he wanted to pursue afterwards, both of which he hopes will facilitate the coalescence of sound science and land management. His research with the IRSS will allow him to work closely with a Vancouver-based remote sensing company to analyze and develop the applications of drones within forestry, which will be used to inform land management and forestry operations.

Bethany Arndt

Growing up in an outdoorsy family in the outdoorsy little city of Nelson, BC, Bethany had little choice but to fall in love with lakes, rivers, mountains, and forests. She loves exploring and discovering more about the intricacies and beauty of the natural world, which she considers God’s Masterpiece. She decided that a career in wildlife/conservation sounded like a good excuse to spend more time in and learning about nature, and has so far enjoyed her summers working in environmental consulting. After graduating high school Bethany moved to the Big City of Kelowna, BC, where she completed her undergraduate degree in Biology. Now she is excited to up the ante again with her graduate studies at the IRSS lab where she will be building models of grizzly bear response to roads. She’s a bit wary of all the people and a campus six times the population of her home town, but locals encourage her that there are many places to escape. Bethany looks forward to spending her time growing to love Vancouver by experiencing the hiking, biking, kayaking, and maybe even some culture. When she needs to hole up and introvert for a while Bethany enjoys reading, walks in the woods, and singing while she pretends to play guitar.

During his spare time, Shangrong loves swimming, hiking, and playing soccer. He enjoys travelling and wants to experience a different lifestyle in Canada.

Cam McClelland

Cam grew up just outside of small town Hinton, Alberta. Having spent most of his young life exploring the backcountry of the Wilmore Wilderness Park on horse back he knew he wanted to pursue a career in wildlife research and conservation. After completing his BSc in Environmental Earth Sciences at the University of Alberta he was able to realize this goal with the fRI Research Grizzly Bear Program. Cam spent four summers and a one year internship with the program working on projects ranging from population dynamics to predation. When not working with the fRI Cam split his time between travelling and ski bumming.

Wishing to expand his knowledge base, Cam will be working with the IRSS lab as an MSc candidate. He will be assessing how habitat availability influences space-time patterns of movement and survival of grizzly bears at fine spatial and temporal scales as well as differentiating movement patterns associated with different levels of landscape connectivity.

Chris Mulverhill

ChrisMulverhillChris was born in Illinois and raised in Texas, where he lived for 13 years. Following years of camping and too much running, Chris developed his passion for the outdoors and dreamed of moving west and living in the woods to learn more about the complicated ecosystems that only existed in pictures. Having finally been cooked to a medium rare in the sweltering Texas heat, Chris left to begin studying at the University of Oregon, where he would go on to earn a BSc in Environmental Science. There, Chris explored his interests in forest biology and geospatial technologies, eventually landing an undergraduate research assistantship under Dr. Chris Bone, investigating topics such as Mountain Pine Beetles, socioeconomic measures of poverty, US Forest Service supply chains, and forest treatments in the American West. Chris’s MSc research at UBC is part of the AWARE program and will examine the ability of ALS LiDAR to assess product mix in forest stands. He hopes to use this information to inform the decisions of forest managers and timber companies in order to improve the health and sustainability of forest resources.

Chris looks forward to life in Vancouver which includes lots of running, camping, eating, and pretending to understand hockey.
