Imre Leader studies extremal combinatorics and Ramsey theory. His Cambridge research profile identifies these areas.[ref]
With Neil Hindman and Dona Strauss, he studied compatibility between Milliken-Taylor systems. The coefficients of two systems cannot be chosen arbitrarily if both are to be monochromatic in the required simultaneous sense. Their theorem identifies a positive-rational-proportionality condition for compressed positive coefficient patterns, sharpening the distinction between individually unavoidable patterns and jointly compatible ones.[ref]
