Titratable Martini


Even protons do not escape our coarse-graining strategy! See how Martini protons hop around in a pH dependent way, protonating amino acids, fatty acids, or titratable groups of dendrimers.

PhD and post-doc positions available

We currently have two positions open in our group:

(1) A PhD position (4yr) on resolving the molecular driving forces behind the switching behavior of light harvesting complexes. Together with experimental colleagues, we would like to unravel the role of PsbS, an important protein that is involved in the switching (which occurs under high light conditions). If you are not afraid of teaming up with experimentalists (these are nice ones, I promise) and running large scale simulations, this is your chance. We might even end up modeling a whole chloroplast !

(2) A post-doc position (2yr) on development of titratable Martini, aimed at improving the model and extending the application range. Our recently introduced method to enable constant pH Martini simulations opens the way to extend Martini into unknown territories, including reactive-Martini. If you would like to be the main explorer, then consider applying.

For both positions, a solid background in computational modeling is required. Interested ? Apply by sending an email to This email address is being protected from spambots. You need JavaScript enabled to view it. including CV, motivation letter, and contact details of at least two references. Application deadline: Sept 1st, 2020. Both positions are available right away, and ideally start before the end of the year.

New: Martini cocktails featuring ionic liquids


Getting bored of the traditional Martini ingredients ? Then try spicing up your cocktail with ionic liquids ! Check out this paper for inspiring recipes, some of which feature fish oil .....

Advanced Memterials



Our TS2CG tool has already inspired some (read: Matthieu Chavent) to create a whole series of new artefacts, opening an entire new field of science. Advanced Memterials ? Membrengineering ? Who comes up with a catchy name ?

We can already envision the next steps, e.g., simulating fusion of two bunnies, or what would you get putting a Martini glass and a bunny together  in a simulation box ? And what would it take to stabilize these highly-curved objects with the right type of lipids and curvature stabilizing proteins ?

Of course the real challenge is now with the experimentalists to make these lipid based nano devices in the lab ....

Simulation of an entire organelle

Simulation of the membranes of an entire mitochondrion ! See how more than 5 million lipids are organized in this amazingly complex organelle, obtained with our new backmapping tool TS2CG.

Hybrid membranes



On (rare) occasions Martini membranes are not good enough, and you might want to simulate with atomistic resolution. But then your system size explodes and you don't have this Anton machine on your desk. What next? Liu Yang figured a way to combine the best of both worlds:
