My LONG-TERM GOAL is to identify factors that impact host-parasite population dynamics using two MODEL SYSTEMS: a fish ectoparasite and a mouse intestinal nematode. Parasites directly impact host health through reduced growth, reproduction and survival with implications that extend to the host population. What is less understood, but possibly of equal importance, is whether the infected host is able to SIGNAL OTHERS OF THE RISK OF INFECTION. Recent results suggest this is possible both in fish and mice, with implications for host-parasite population dynamics and for pathways of host-parasite co-evolution.

我的长期目标是使用两个模型系统识别影响宿主-寄生虫种群动态的因素：鱼体外寄生虫和老鼠肠道线虫。寄生虫通过减少生长、繁殖和存活直接影响宿主的健康，影响到宿主人口。人们不太了解，但可能同样重要的是，受感染的宿主是否能够向其他人发出感染风险的信号。最近的结果表明，这在鱼和老鼠身上都是可能的，这对宿主-寄生虫种群动态和宿主-寄生虫共同进化的途径都有意义。
