. He retired in 2011. Lohse's research focused on the thermodynamics of mixing polymer blends, neutron scattering from polymers, the use of block and graft copolymers to enhance blend compatibility, the control of rheology by molecular architecture, nanocomposites, and improvement of polymer products. With

, he published the textbook ''Polymeric Compatibilizers''. His most cited works concern the connection between polymer molecular weight, density, chain dimensions and melt viscoelastic properties, and packing length in linear polymer melts.
