Abstract

Polyploid Evolution / Wheat Genetics and Breeding

Polyploid Evolution

I'm studying recently formed polyploid plant species endemic to Switzerland. Cardamine insueta and Cardamine schulzii emerged within the last 100–150 years in a small Swiss village. Due to their short evolutionary history, these species are found only in this region.

Their recent origin provides a unique opportunity to investigate the immediate effects of polyploidization, a major driver of speciation that occurs frequently in plants. By applying ecological, genomic, and population genetic approaches, I aim to uncover the origins of polyploid evolution using these exceptionally rare species.

Wheat Genetics and Breeding
I integrate UAV high-throughput phenotyping technology with the Asian bread wheat nested association mapping (NAM) population.

This NAM population was designed to capture the genetic diversity of Asian wheat, which accounts for approximately 40% of global wheat diversity but remains largely untapped in modern breeding.

By leveraging UAV high-throughput phenotyping with this population, I aim to identify beneficial genes associated with physiology, disease resistance, and yield increase in Asian wheat genetic resources.
