The aim of my research program is to uncover the mechanisms that drive adaptive radiation -- the rapid origin and divergence of new species from a common ancestor. Many (perhaps even most) species on earth have arisen during such bursts, so they are key to understanding the origins of life’s extraordinary diversity. Cases of adaptive radiation still in their early stages have great advantages for study because the rate of evolution is sped up, new species are still forming, intermediate forms are still extant, evolutionary events are frequently repeated, and young species remain capable of hybridizing. These features allow us to make rapid progress using a combination of observational, experimental, and genetic studies.

我的研究计划的目的是揭示驱动适应性辐射的机制--来自共同祖先的新物种的快速起源和分化。地球上的许多物种(甚至大多数物种)都是在这种爆发期间出现的，所以它们是理解生命异常多样性的起源的关键。适应性辐射仍处于早期阶段的情况具有巨大的研究优势，因为进化速度加快，新物种仍在形成，中间形式仍然存在，进化事件经常重复，年轻物种仍有能力杂交。这些特征使我们能够通过结合观察、实验和遗传研究取得快速进展。
