Andrew is a wildlife biologist, conservation leader, strategic planner, and educator with more than 25 years of experience in applied wildlife research and conservation. His work spans taxa ranging from large carnivores to anurans, with research addressing wildlife population monitoring, endangered species recovery, invasive species control, and landscape-scale habitat management. Throughout his career, he has focused on weaving together robust scientific evidence with collaborative and inclusive decision-making processes to develop pragmatic and enduring conservation solutions.

In recent years, Andrew has increasingly focused on building the people, partnerships, and organizations that underpin lasting conservation outcomes. He is passionate about developing the next generation of conservationists and helping scientists and practitioners become more effective communicators, leaders, and collaborators. He has led conservation organizations, built multidisciplinary teams, and facilitated collaborative conservation planning across North America and internationally. Andrew especially enjoys drawing on his experiences as a field biologist, researcher, nonprofit leader, and systems thinker to help others develop the skills, confidence, and collaborative capacity needed to tackle today’s complex conservation challenges.
