How cells clean house across the eukaryotic tree of life.

We study how autophagy — the cell's own recycling system — evolved across life, and how it keeps organisms healthy when things get stressful.

Selective autophagy — an autophagosome engulfing cellular cargo
Why we do this

We want to know how cells keep themselves alive — and how they've managed it for two billion years.

Almost everything we know about cellular quality control comes from a handful of lab organisms. We take a wider view. By sampling the astonishing diversity of the eukaryotic tree of life, we find autophagy pathways no one has seen before — then work out how they actually work, using imaging, biochemistry, and genetics. It's cell biology with an evolutionary heart, and it keeps surprising us.

The pathway

From phagophore to vacuole

Selective autophagy captures damaged or unwanted cargo in a growing double membrane, packages it, and delivers it for recycling — a journey our lab has helped map, including the discovery that plant autophagosomes mature into amphisomes before reaching the vacuole.

Research

Four questions we're chasing

Autophagy is the cell's recycling crew: it grabs damaged or unwanted parts and breaks them down so the cell stays healthy and in tune with its surroundings. Here's where we dig in.

01

Receptor discovery

We comb through the diversity of life to find the receptors that decide what a cell recycles — then work out, in detail, exactly how they do it.

02

ER homeostasis & UFMylation

Building on our discovery of the conserved receptor C53 and its regulation by the enigmatic UFMylation pathway, we combine evolutionary cell biology, RNA biochemistry, and omics to illuminate UFMylation's hidden roles.

03

Organelle quality control

How do cells keep each of their organelles healthy? Our discovery that cell-wall damage induces ATG8ylation of the tonoplast — a non-canonical form of autophagy — is one entry point into how quality-control pathways safeguard the vacuole, ER, chloroplasts, mitochondria, and beyond.

04

Cell-type specific autophagy

Using tools we've developed, we investigate how specialized autophagy pathways differ between cell types and coordinate to sustain whole-organism homeostasis under diverse stresses.

Highlight

A conserved route to protein quality control

By comparing autophagy interactomes across species, we uncovered CESAR — a selective-autophagy receptor that recognises ubiquitinated protein aggregates and hands them to the ATG8-decorated autophagy machinery. This quality-control route is conserved across the plant lineage, and sits at the heart of our comparative, evolution-first approach.

Jose Julián Valenzuela wins an FWF-ASTRA Prize for vacuolar quality control

Former Dagdas lab member Jose Julián Valenzuela — first author of our study on ATG8ylation of the vacuolar membrane — has been awarded a prestigious FWF-ASTRA Prize 2026, worth roughly €1 million over five years. Now leading his own group at BOKU University, he will explore how "vacuolar quality control" lets plants cope with alkaline soils, studying model plants and climate-resilient crops such as quinoa to help build more resilient agriculture.

How we work together

Our code of conduct — R.I.P

Three commitments guide everything we do:

Respect. We treat each other, and our science, with care — kindness, inclusion, and honest, constructive feedback.
Integrity. Honest data and honest credit — clear records, fair authorship, and open science by default.
Passion. We stay curious, take smart risks, invest in each other's growth, and keep it human.
Our commitment to your career: when postdocs move on, we encourage them to take their projects with them — because helping people launch independent careers is part of the deal.
