With his community ecology perspective Dr. Pearson examined past ecological management interventions and assessed the nature of any unintended consequences. He described a community assessment framework he is developing which along with Fuzzy Cognitive Mapping - a semi quantitative modeling approach - could aid in avoiding many future unwanted outcomes following a ecological intervention. The applicability of his assessment framework and modeling approach to gene drive research and development was discussed.
