    Job description

    In charge of the maintenance and operation of the laboratory, assistance and advice to users in experimental procedures, and student training and supervision.

    Research interests

    My research focuses on the interaction between environment and ecomorphological variation, and its influence on populations and species diversification. One aspect of this research involves investigating patterns of ecological and morphological evolution in species of Neotropical fruit-eating bats of the genus Artibeus. Specifically, I evaluate the association between species’ geographic distribution and inter-specific morphometric variation by incorporating ecogeographic information through the use of geographic information systems. This study focuses on how the interaction between distribution, habitat use, and phylogenetic constraints influences morphological variation in these bats.
    Also, I explore the effects of extreme human-induced levels of environmental stress on bank vole (Myodes glareolus) populations from Chernobyl, Ukraine. This study evaluates the ecological effects of the Chernobyl Nuclear Plant disaster in the morphological configuration of this small mammal based on a variety of well-established ecomorphological and ecogeographical methods, which include linear and geometric morphometric techniques and multivariate statistical analyses.

    In addition, as a visiting student at University of Michigan, I have collaborated with Dr. Lacey Knowles in the study of the genetic consequences of habitat disturbance in the Pacific giant salamander (Dicamptodon tenebrosus). In this project, we assessed existing genetic structure in populations of this species from the Pacific Northwest of the US to test the hypothesis that environmental disturbance reduces within population genetic variation but increases intrapopulation divergence. I have also worked at the Mammal division assisting on museum database management inventorying and documenting the museum collection.
