Weiqi Z.

Quantitative social science and data science professor with an MBA

I am a published quantitative social scientist and data scientist. One of my books titled "Introduction to Quantitative Social Science with Python" is published by Taylor and Francis. I also have an MBA. Outside Upwork, I provide data-related services to business, law firms (expert witness), and academic researchers (wz-consulting.com). I have advanced statistical analytical skills that can be applied to commercial and academic projects. Additionally, for academic research, I have experience in publishing peer-reviewed academic works and have served as editor or reviewer for multiple journals. As a trained academic, I follow high standards of procedures for data management and analysis. I always seek to provide objective and reliable instead of easy solutions and answers. As a native Chinese/Mandarin and Shanghainese speaker, I also offer translation between English and Mandarin or Shanghainese, and tutoring service.
