Forest Mensurationists and Biometricians


 lemay Dr. Valerie LeMay, Professor at UBC.I am a Registered Professional Forester in British Columbia and an officer of the International Union of Forest Researchers (IUFRO). I teach forest measurements and applied statistics for forest and other natural environments and was honored with the UBC KillamTeaching Award in 2004.  My research interests include developing methods and estimating equations for a wide variety of scales from leaves to landscapes, mostly for BC, but I have worked with graduate students in equatorial environments.For me, forestry encompasses all elements of forest systems, and allows me to pursue my avid curiousity in the natural world including forests, deserts, and mountain environments.  Hiking through natural terrain also allows me to pursue another passion of singing loudly in places where no one is likely to mind.

 peter1 Dr. Peter Marshall, Professor and Associate Dean, Faculty of Forestry, UBC.Although administrative issues take a considerable portion of my time these days, I still like to teach and conduct research in the quantitative aspects of forest management. At present, I teach an undergraduate course in forest measurements and a graduate course in sampling design and theory. My research over the last several years has been primarily focused on modeling various components of the dynamics of complex (uneven-aged and/or mixed species) forest stands. I remain active in the Association of BC Forest Professionals (where I am a former president) and the Canadian Institute of Forestry, where I am First Vice-President. I also have a strong interest in matters pertaining to accreditation of forestry programs at academic institutions by professional bodies.Outside of forestry, my most passionate interests are cooking and eating, and working out in a variety of ways, including hiking, to try to keep my weight under some semblance of control given my love of good food.

 People_clip_image002 Kahlil Baker, MSc Candidate at the University of British Columbia.My research interests include looking at using reforestation as an economically viable land-use option in Central America. I am working with Dr. Valerie Lemay to develop growth and yield equations for promising yet understudied species native to the tropical dry forests of Costa Rica and Nicaragua. The second phase of my research involves incorporated this information into an economic model to forecast the feasibility of such species in terms of timber production and carbon sequestration.
In addition to my research I work with Taking Root, a non-profit organisation that develops reforestation projects in collaboration with subsistence farmers in Nicaragua.
I’ve been visiting, working or living in Central America for over 10 years and hold a bachelor’s degree in economics from Concordia University.  I love being outdoors, travelling and am always willing to take on new challenges.

Derek_s Derek Sattler, MSc at the University of British Columbia.After graduating from the Universitiy of Alberta’s Department of Zoology, I decided that forestry was far more exciting. Acting on this decision, I began work at a resource management consulting firm in Edmonton, where I gained extensive knowledge and experience working with forestry related modeling tools. As a grad student, I am focusing my attention on growth and yield modeling.When I am not modeling forests, I like to satisfy my passion for climbing by hitting the boulders hard. Aside from climbing, there is little else I enjoy. One exception may be relaxing on the beach with friends.

Hugh Hugh Carter, MSc at University of British Columbia.I am a Registered Forest Technologist in British Columbia. I completed my BSc in Biology at the University of Waterloo 1999, a Forestry Diploma at BCIT 2001 and Renewable Resource Management Diploma at BCIT 2002. I worked in the field for Olympic Resource Management and Kerley & Associates Ltd. and was involved a variety of inventory and growth and yield projects. I am currently working for J.S. Thrower & Associates Ltd. as an appraisal cruise compiler and analyst.My passions in the world of forestry are sampling and growth and yield. My MSc thesis is looking at the use of variable radius plots for measuring growth. I am a lover of music, beer & wine, and the company of good people. I enjoy snowboarding, mountain biking, hiking and golf when I can find time, and when I am not doing any of these I am just enjoying the fine city of
Rueben Rueben Schulz, MSc at the University of British Columbia.I completed my BSF at UBC in 2001 and was introduced to GISduring this time. I furthered my interest in GIS at BCIT after which I was loured back to UBC. My masters work involves trying to predict historic wildfire parameters from forest inventory data. This work forces me learn more about statistics, which I hope will be a useful background once (if?) the GIS industry matures and starts to analyze all of the spatial data we are collecting.When I have spare time (or not) I am involved in an open source GIS project (to keep myself learning), and hiking and building hutswith the VOC.

I subsequently worked as a biometrician with J.S. Thrower & Associates Ltd., specializing in forest inventory design and analysis.But since coming to Yale my interests have again shifted back tomodelling, and my dissertation research is focused on developing a statistical framework for modelling forest tree mortality. Other recent research projects have included the probabilistic foundations of line intersect sampling and methods to handle the boundary overlap problem in natural resource inventories.
Christina1 Dr. Christina Staudhammer, Assistant Professor of Forest Biometrics at the University of Florida.I am currently on the faculty of the School of Forest Resources and Conservation at the University of Florida (Gainesville). I teach natural resources sampling and advanced biometrics to foresters and others involved in the natural resources area. My research interests broadly include experimental design and mixed model analysis, with a particular interest in tropical forests (and especially, Brazil nuts). I also work with large, managed pine plantation data sets, looking at methods for quantifying distributional differences under various silvicultural and genetic treatments. More recently, I obtained a grant to look at the effect of hurricanes on urban forests in the southern United States. The outcome of this project will be community- and landscape-scale models for hurricane damage and debris for trees growing in urban environments. I obtained a BSc in Mathematics from U.C. Davis in 1990.I did my Masters and PhD work at the University of British Columbia, finishing in 2004. Although my passions are windsurfing and rock climbing, in Florida, I spend most of my free time running and cycling.
 Celine Dr. Celine Boisvenue, PhD University of Montana.  I completed my Masters at UBC in Dec.1999.I have recently completed my PhD at the University of Montana in Missoula, MT, USA with the Numerical Terradynamic Simulation Group (NTSG).  My PhD research looks at the effects of climate change on forests and explores our ability to accurately measure forest productivity.I plan on continuing my career in applied research contributing to the estimation of carbon content in forests, and forecasting the effects of climate change on forest ecosystems through integration of cross-scale data sources and modelling. I am presently a visiting researcher at Laval University in Dr. Hank Margolis’ working group within the Canadian Carbon Program. My current projects include, the publication of my dissertation chapters, testing a frame work to integrate climate sensitivity and carbon accounting into existing growth and yield models, a framework I built during my first few years at the University of Montana working with Dr. Kelsey Milner, and establishing the data basis for cross-scale carbon accounting at regional scales.

Prior to moving to Missoula for my PhD research, I established and ran a small consulting firm in Nelson, BC (Canada), specialized in quantitative issues related to forest ecosystem resources and dynamics, skills I acquired during my Master’s degree in biometrics at UBC.
