About

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, a model dark taxon.

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 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 joined NTNU as an Onsager Fellow 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.

Research

I am a biodiversity scientist and entomologist. My research focuses on Dark Taxa: species-rich but poorly known groups that comprise the majority of Earth’s biodiversity. I combine taxonomy, DNA barcoding, morphometrics, and ecological modelling to develop scalable workflows for discovering species, linking historical collections to molecular data, and analysing community structure in hyperdiverse systems. I am a specialist on scuttle flies (Diptera: Phoridae), a model dark taxon.

I serve as co-lead of the Scientific Research working group of CETAF (Consortium of European Taxonomic Facilities), where I promote integrative, collections-driven approaches to biodiversity science and advocate for the inclusion of Dark Taxa in European research and policy frameworks.

I leads tasks in the newly funded Horizon Europe projects BGE+ and TETTRIX, where I will be contributing expertise in integrative taxonomy, molecular workflows, and the mobilisation of natural history collections. In these projects, I will work to strengthen research infrastructures, develop best practices for biodiversity data generation and interoperability, and ensure that underrepresented taxa are fully integrated into large-scale European biodiversity initiatives.

Resolving biology’s dark matter: species richness, spatiotemporal distribution, and community composition of a dark taxon

We use megabarcoding to assess a model dark taxon, investigating species diversity, variation across time and space, and the environmental drivers. We demonstrate how dark taxon research can provide critical insights in the era of climate change.
