“My research focuses on the use of molecular genetic data to explore the origin and maintenance of biological diversity.  Current projects include: 1) molecular phylogenetic studies on the early radiation of all living birds, as well as specific groups (raptors, nightbirds), 2) Molecular, morphological, and behavioral studies of hybrid zones as models of speciation, and 3) integrative studies of avian biogeography and conservation.”

“As a postdoc in the Braun lab, I am involved in two projects. First, I am studying the phylogeography of endemic avifauna of the Tepui Highlands of northern South America to better understand the evolutionary origins of these taxa.  Pantepui avifauna occur mainly at the species and subspecies level, reflecting an ongoing process of diversification.  I will be testing a number of competing hypotheses that have been proposed to explain Pantepui avifauna endemism in various contexts; temporal, spatial, and ecological.  This research may offer important insights into mechanisms underlying diversification and community assemblage.  Second, I am involved in an international partnership of scientists, educators, policy experts and others working to recover the critically endangered Red Siskin, Sporagra (Carduelis) cucullata, in Venezuela. My participation involves contributing to the development of a comprehensive recovery plan and developing molecular tools for genomic management and monitoring of an ex situ breeding colony and, eventually, reintroduced flocks. I am also working to expand conservation education and outreach, an essential component of the campaign to achieve sustainable biodiversity.”

“My research at the Smithsonian Institution uses sequence capture, genotyping-by-sequencing and high-throughput sequencing to improve Lim_photo_2our understanding of how geography and environmental factors drive divergence, speciation and distribution of Southeast Asian birds. One specific project uses a probe-set based on ultra-conserved elements (UCEs) to conduct comparative phylogeographic study of five passerine species from Indo-Burma and Sundaland. The sequence capture approach adopted here allows me to interrogate modern genetic samples, as well as old museum specimens. I am also interested in using data generated through genotyping-by-sequencing to probe genomic changes across hybrid zones and across environmental gradients.”

“My research focuses on molecular phylogenetics, specifically, inference using genome-scale markers. I am looking at ultra-conserved elements (UCEs), using available genomes to investigate potential function, and developing best methods for using UCEs to inform phylogeny. My study system are the nightbirds, swifts and hummingbirds (Caprimulgiformes + Apodiformes = Strisores). I am applying UCEs to elucidate the evolutionary switch between nocturnality and diurnality in these birds, as we know that the diurnal Apodiformes are nested within the nocturnal/crepuscular Caprimulgiformes. To this end, I am investigating the molecular basis of nocturnal vision across the avian tree of life by studying the molecular evolution of opsin sequences. Ultimately this will allow us to answer questions about the evolutionary advantages and the adaptive basis of nocturnal and diurnal lifestyles.”
