I am interested in the ecological, social, and physiological factors that influence, and are influenced by, individual variation in behavior and reproduction. My developing research program focuses on the behavioural ecology and life-history of wild vervet monkeys (Chlorocebus pygerythrus). Vervets are characterized by a relatively rapid life history pace, sex-specific dominance hierarchies, and sexual dichromatism, with pronounced intermale variation in scrotal and penile coloration. The vervet study population at Lake Nabugabo in southwestern Uganda, lives in a humanized landscape that when combined with the vervets’ semi-terrestrial nature, makes them relatively easy to observe. The Nabugabo vervet population offers a relatively unique opportunity to investigate how access to energy-rich human foods influences development and reproduction. The current study group (followed since 2011) will be supplemented by two additional neighboring groups that I began habituating in July 2015. Thus, over the next five years, I will build on my experience in the analysis of the socioendocrinology of male reproductive strategies and my existing collaborations to examine 1) the emergence, maintenance, and signaling of male dominance rank, and 2) the ecological influences on breeding seasonality and how these influence the timing of male life-history events.

我感兴趣的生态，社会和生理因素的影响，并受到影响，在行为和繁殖的个体差异。我正在发展的研究计划侧重于野生长尾猴（Chlorocebus pygerythrus）的行为生态学和生活史。长尾小蠹的特点是相对较快的生活史节奏，性别特异性的优势阶层，和性二色性，与阴囊和阴茎着色显着的雄性间的变化。在乌干达西南部的纳布加博湖，研究中的黑尾长尾雉种群生活在一个人性化的景观中，当与黑尾长尾雉的半陆地性质相结合时，使它们相对容易观察。Nabugabo vervet种群提供了一个相对独特的机会，可以调查获得富含能量的人类食物如何影响发育和生殖。目前的研究小组（自2011年以来）将由我在2015年7月开始习惯的另外两个相邻小组补充。因此，在接下来的五年里，我将建立在我的经验，在男性生殖策略的社会内分泌学分析和我现有的合作研究1）出现，维护，和男性主导地位的信号，和2）繁殖季节性的生态影响，以及这些如何影响男性生活史事件的时间。
