Approach to Teaching
Passion and genuine interest in subject matter are vital to bringing course material to life in the minds of students. Such expression of excitement towards the curriculum coupled with demonstrations of its applicability can inspire a profound desire and capacity for learning. Alignment of these thrusts with various clear examples during lectures is a certain method for grounding theories with reality, providing links to which students can relate. The use of suitable vocabulary and teaching techniques, directed at the audience, ensures that the teaching objectives serve their intended purpose, neither boring nor baffling the minds of learners. Achieving the goal of maximum conveyance of knowledge occurs when presenting subject material in an exciting fashion, directed at the audience and when learning barriers are recognized and minimized such that all parties can communicate at a common level. Finally, accessibility for consultation and the provision of constructive criticism are crucial to complete the feedback-loop in the learning cycle. Fostering these hallmarks creates an encouraging and constructive educational atmosphere that lends itself to the positive development of independent thinkers and learners.
My teaching goals link clearly with my teaching philosophy, with primary goals to inspire independent thinking and to develop problem-solving skills. Most people can learn technical skills, but learning to think is an invaluable ability regardless of the discipline. I strive to convey my excitement towards science through the inclusion of numerous case studies and illustrations to which students may relate. Using examples from my personal research, the media, and from the backgrounds of my students, I hope to paint a vivid and stimulating portrait of science, problem solving, and geographic analysis in their minds. The integration of theories with illustrative examples acts to personalize the learning experience and provides tangible relevance to important concepts. When students demonstrate their ability to think and solve problems through the completion of assignments, they experience accomplishment. Honest and objective evaluations of these accomplishments provide students with constructive feedback and further coaching. I demand quality from my students, and to assist them meet this requirement, I make myself readily available for consultation and guidance. When students demonstrate critical thinking skills to overcome hurdles independently, I see their personal satisfaction, which elevates a feeling of teaching achievement within me.
My core interests incorporate aspects of spatial pattern, accuracy and uncertainty, and boreal disturbance analyses. I integrate remote sensing, GIS, and spatial statistics to better understand the physical environment.

Approach to Teaching
Passion and genuine interest in subject matter are vital to bringing course material to life in the minds of students. Such expression of excitement towards the curriculum coupled with demonstrations of its applicability can inspire a profound desire and capacity for learning. Alignment of these thrusts with various clear examples during lectures is a certain method for grounding theories with reality, providing links to which students can relate. The use of suitable vocabulary and teaching techniques, directed at the audience, ensures that the teaching objectives serve their intended purpose, neither boring nor baffling the minds of learners. Achieving the goal of maximum conveyance of knowledge occurs when presenting subject material in an exciting fashion, directed at the audience and when learning barriers are recognized and minimized such that all parties can communicate at a common level. Finally, accessibility for consultation and the provision of constructive criticism are crucial to complete the feedback-loop in the learning cycle. Fostering these hallmarks creates an encouraging and constructive educational atmosphere that lends itself to the positive development of independent thinkers and learners.
My teaching goals link clearly with my teaching philosophy, with primary goals to inspire independent thinking and to develop problem-solving skills. Most people can learn technical skills, but learning to think is an invaluable ability regardless of the discipline. I strive to convey my excitement towards science through the inclusion of numerous case studies and illustrations to which students may relate. Using examples from my personal research, the media, and from the backgrounds of my students, I hope to paint a vivid and stimulating portrait of science, problem solving, and geographic analysis in their minds. The integration of theories with illustrative examples acts to personalize the learning experience and provides tangible relevance to important concepts. When students demonstrate their ability to think and solve problems through the completion of assignments, they experience accomplishment. Honest and objective evaluations of these accomplishments provide students with constructive feedback and further coaching. I demand quality from my students, and to assist them meet this requirement, I make myself readily available for consultation and guidance. When students demonstrate critical thinking skills to overcome hurdles independently, I see their personal satisfaction, which elevates a feeling of teaching achievement within me.
