Iam interested in how urban neighborhoods are defined by racial groups. having started my career as a journalist, i have become an influential sociologist by recognizing urban problems due to city boundaries based on social class and race. this continues to be a main focus of sociological research.

This sociologist is "Robert Park".

Robert Park (1864– 1944) was one of the founders of American sociology, he began as a writer however moved to the University of Chicago and framed the Chicago School, which built up a methodology in light of doing reasonable research that could be connected to this present reality. He was to a great extent inspired by the structure and outline of urban communities, to be specific how they are shaped base wear racial and social class lines. Stop's work has been influential to the point that numerous sociological investigations are as yet in view of his underlying work in urban settings.
