The best graphical representation of our research topics I could think of is a dripping faucet. We model with molecular resolution structure and chemical dynamics of finite pieces of matter (clusters, droplets, systems with extended surfaces, solvated biomolecules,...). As faucets do (well, not the one below), we have a warm button (red) - systems at ambient conditions, and a cold button (blue) - cryogenic systems close to 0 K. Below is a list of several of our hottest (and coolest) topics.
