Very excited to see our @nikogeldner.bsky.social lab x Feng Zhou lab work featured on the cover of Science!
(1/5) We reveal how root architecture and nutrient leakage shape spatial patterns of microbial colonization, moving beyond traditional models of uniform exudation.

Call for a tenure-track position at our Department of Plant Molecular Biology in Lausanne! We are searching for promising early-career researchers in the broad field of plant-organismal interactions. Deadline: November 30, 2025 - Please re-post!

Interestingly, plant epidermal cells have a strikingly similar lobate shape, which provides structural rigidity. We teamed up with plant biologists R. Smith and M. Majda. In silico modeling showed that, similar to plants, the lobate shape of LECs helps prevent lumen collapse in lymphatic capillaries
