My sister Louise Kellogg was a leading geophysicist specialising in geodynamics: the study of how movement deep in the interior of the earth drives surface phenomena like the movement of the crust via plate tectonics. She discovered new structures deep in the earth's mantle, new connections between geophysics and geochemistry, and consequences of deep earth phenomena evident at the earth's surface. She built rich and useful mathematical and computational models to interrogate geodynamic processes. She was also devoted to equity and inclusion at all levels of science, and led by example. A very incomplete picture of her scientific contributions is on her Wikipedia page, her faculty page at UC Davis is here, a memorial page is here, and collected remembrances are here.
