Lohse joined
Exxon Mobil Corporation in 1980, starting in the Long Range Polymer Research Group. In 1987, he joined the Corporate Strategic Research Labs of ExxonMobil Research & Engineering Co where he worked with
Edward Kresge and
Sudhin Datta. 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
Sudhin Datta, 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. ==Awards==
