Organisms live in an uncertain and challenging world where the critical measure of success (fitness) is the number of progeny they produce that subsequently also reproduce. Processes operating during the breeding cycle can especially influence fitness. In birds, for example, choice of an appropriate mate, allocation of energy and nutrients to offspring, and external factors such as parasitism are all critical. To better understand why fitness varies among individual birds, my research focuses on four major areas of study:

生物体生活在一个不确定和具有挑战性的世界中，成功（适应性）的关键衡量标准是它们产生的后代的数量，这些后代随后也繁殖。在繁殖周期中运行的过程尤其会影响适应性。例如，在鸟类中，选择合适的配偶，为后代分配能量和营养，以及寄生等外部因素都是至关重要的。为了更好地理解为什么不同鸟类的健康状况不同，我的研究集中在四个主要研究领域：
