The objective of my research program is to understand the role that stress plays in nature, both in terms of individual effects and of population consequences. The stress axis is one of the key physiological systems that mediates the relationship of an organism with its environment, acting both on a daily basis to affect physiology and behavior and in response to acute and chronic environmental stressors (either biotic or abiotic). The axis and related components are central to long-term evolutionary adaptations to particular ecological challenges. Thus, the axis is a key part of the neuroendocrine pathway that integrates these challenges while at the same time playing a critical role in life history decisions to reproduce, to grow, and to allocate energy into storage. My lab uses the tools of endocrinology, animal physiology and metabolism, epigenetics, population ecology, and behavioral manipulations to study the stress axis. Our primary research models are wild mammals throughout Canada. Our goals over the next five years focus on three main areas:

我的研究计划的目标是了解压力在自然界中所扮演的角色，包括对个人的影响和对人口的影响。应激轴是调节生物体与其环境关系的关键生理系统之一，每天都会影响生理和行为，并响应急性和慢性环境应激源（生物或非生物）。该轴和相关组件是针对特定生态挑战的长期进化适应的核心。因此，轴是神经内分泌通路的关键部分，它整合了这些挑战，同时在生命史决策中发挥着关键作用，包括繁殖、生长和分配能量储存。我的实验室使用内分泌学、动物生理学和新陈代谢、表观遗传学、群体生态学和行为操作的工具来研究压力轴。我们的主要研究模型是加拿大各地的野生哺乳动物。我们未来五年的目标集中在三个主要领域：
