About
I am a Dark Taxon Entomologist employing integrative taxonomic techniques to the hyperdiverse but poorly known groups that dominate our planet's biodiversity. I am a specialist on the fly genus Megaselia (Diptera: Phoridae) and I use this group as a model taxon for developing new strategies for studying the world's most challenging groups.
I am originally from California, where I got my B.S. in Entomology from the University of California Riverside. I later worked on the BioSCAN project at the Natural History Museum of Los Angeles, where I got hooked on the hyperdiverse fly family Phoridae, also known as scuttle flies.
In 2017, I was awarded a Swedish Taxonomy Initiative grant to work on scuttle fly material from the Swedish Malaise Trap Project at Station Linné on the island of Öland. This work became part of my PhD thesis in the Ronquist Lab at Stockholm University. My thesis tackled questions about the diversity of scuttle flies, but also developed integrative methodologies to handle "dark taxa", groups that are hyperdiverse and abundant but poorly known due to the complexity of their study.
My work on dark taxa continued and expanded when I took a position with the Center for Integrative Biodiversity Discovery at the Museum für Naturkunde in Berlin from 2021-2024. There, our team employed molecular techniques in combination with robotics and machine learning to accelerate biodiversity science.
In 2024 I took a position at NTNU with the goal of leading a team of innovators who are similarly interested in exploring the richest and most abundant taxa on earth with integrative, multidisciplinary perspectives.
