Interests & Activities

Foodweb and community ecology of non-indigenous (invasive) species.

My field and laboratory research attempts to determine the direct and indirect interactions and mechanisms through which non-indigenous species impact resident foodwebs and ecosystems.  I employ a combination of empirical and theoretical tools to understand these interactions across multiple spatial and temporal scales.
My pedagogical research seeks to increase student engagement in the entire teaching and learning process.  I pursue this through identifying the importance of interdisciplinarity in teaching – Why do I need to study math if I am interested in biology? Additionally, I seek to discover techniques and strategies that increase student involvement in the classroom, enhancing student activity in the classroom and their general desire to learn and apply learning concepts.

Research

My primary research interests deal with how populations of non-indigenous (invasive) species interact with resident species over multiple spatial and temporal scales. The main thrust of my research highlights the importance of indirect interactions as a mechanism by which non-indigenous species impact these systems. My research to date has combined these ideas with quantitative theory and empirical studies in a number of managed and natural systems. I use a number of statistical approaches, including multivariate and spatial statistics, to address both applied and fundamental questions. The ultimate goal of my research is to ascertain the key interactions by which non-indigenous species impact native ecosystems and how we may predict the outcome of these impacts for conservation purposes.
I additionally have an interest in how scientific research is perceived in the media and society in general. With the global problems we face today, the importance of sound scientific research is ever important, but how the results of such studies are communicated and understood by society is a source of confusion and misinterpretation. I find this dilemma very interesting and an important topic that should be highlighted in science education.
My pedagogical research interests include the development and communication of teaching and learning methods, which enhance the student experience in the classroom and laboratory.  This research follows two main avenues.  First, how we can advance the importance of interdisciplinarity in university classrooms and identifying the specific pedagogical methodologies that make this more attainable to Instructors.  Secondly, I have an interest in the balance between student engagement and student entertainment in the classroom. There exists a fine line between effectively reaching students with novel teaching practices and practices that become mere entertainment, rather than techniques that enhance student learning.
