I am interested in criminology, criminal justice, empirical legal research and socio-legal studies in China. With my thesis, I hope to systematically demonstrate the social investigation scheme in China’s juvenile criminal justice system, with an emphasis on qualitative social science research methods, like participant observation and semi-structured interview. I intend to discuss how is the social investigation conducted by a third party, and what factors in the report may affect the judge’s decision in sentencing in China.
