About Me

Research Interests

For my PhD dissertation, I study the evolution of miniature minnows from Southeast Asia. These minnows, such as Paedocypris and Danionella, are some of the smallest fishes in the world. Yet, they are closely related to the model organism zebrafish. The zebrafish's developmental biology has been heavily studied, and its genome has been sequenced. This provides an excellent resource to compare with other minnows, making minnows a potential model system to study vertebrate evolution. My dissertation work involves comparative phylogenetics, phylogenomics, and transcriptomics, to study the evolutionary history of these fishes and the evolution of their genes.


I am also interested in the diversity of loricariids (suckermouth armored catfishes). As an aquarist, I grew to love these fish through my experience keeping and breeding them. Currently, my work on loricariids is focused on their taxonomy, or the naming and classification of species. There are over 800 species of loricariid catfishes, making it one of the most diverse fish groups. There remain many species unknown to science, and I am describing some of these species in my studies.
