• About Me

    Doctoral Student

    Temple University

    I am a graduate student under Matt Helmus and member of the Integrative Ecology Lab in the Biology Department at Temple University in Philadelphia, Pennsylvania.


    Ecologists have long been interested in mechanisms that increase and decrease biodiversity on Earth and the effects that they have on organisms' interactions and functions. These efforts are increasingly important in the current global Anthropocene Extinction Event, which is accelerating biodiversity loss beyond its typical balance with accumulation. I count myself among those working to better understand and conserve biodiversity by leveraging contemporary tools and methods.

    Why Herpetology?

    The reason why I study amphibians and reptiles

    As far back as I can remember, I have always felt a strong interest in reptiles and amphibians. These organisms are great examples of the diversity and adaptability that can be found in nature. As a result, they are incredible focal taxa for studying how organisms interact and respond to their environments.


    In this day and age, the need to be "eco-aware" is global. Often, an environment will shift in response to rapid change, and the way species react can indicate what is to come. Much like canaries in coal mines, amphibians and reptiles have become prime examples of such species, which makes them great model organisms. By understanding patterns in herpetofauna, we can make sense of broader ecological phenomena that can be applied to other systems as well.

    Balancing biodiversity in a constantly changing world

    Community Assembly

    A key question in ecology is: "What factors shape the presence and abundance of species?" I apply this question within a community context to measure and ask how groups of species that interact regularly are able to coexist despite numerous ecological similarities. Currently, I am looking at how some species of burrowing skinks in the genus Brachymeles are able to coexist in numerous communities throughout the Philippines, despite a high degree of perceived ecological overlap. One of the key observations among these assemblages is that without exception, no two species have the same gross morphology within a single community. Further, the same basic phenotypic categories manifest in different communities across the archipelago, which begs the question: what is driving the composition of these communities in a repeated fashion?

    Functional Diversity of Ecological Communities

    Ecological communities contain species that are adapted to their environment differently. Adaptive differences reduce the likelihood that similar species compete and displace one another, often increasing species richness in a given habitat. Such differences can be related to phenotypic traits readily via Simpsonian adaptive landscapes, and models have been developed recently to detect the number and membership of adaptive peaks on macroevolutionary timescales. Changes in Simpsonian adaptive landscapes through time provide a unique view into the relationship between species richness and the range of roles held by species in a community (functional diversity). I am investigating if patterns of convergent adaptive optima characterize assemblages of lizards in the genus Leiocephalus throughout the Caribbean islands. Furthermore, I plan to ask whether introduced species have displaced extinct Leiocephalus and influenced adaptive peak shifts in extant lineages. In future research, I will expand these questions to encompass Caribbean herpetofanual communities at large.
