Dan Hill, a Humboldt Analysis Fellow on the College of Saarland, is visiting the Interface Group this week (Wednesday to Friday, 4-6 January). The College of Saarland is simply exterior Saarbrücken in northwest Germany. His host for the go to is Dave Lloyd. They’re working collectively on varied questions in sample formation, specifically dihedral patterns close to a Turing instability and on localised radial patterns. Dan’s webpage is right here, and the snapshot beneath exhibits Dan and Dave taking a break from scribbling on the blackboard.
