With over 10 years of work experience in data science and machine learning, I am a Senior Manager of Machine Learning Science at Expedia Group, where I lead science initiatives for the People Analytics and Experience design (PAX) team. My mission is to leverage data and insights to enhance employee engagement, performance, and well-being, and to support Expedia's strategic goals and values. My studies in economics and China studies also enable me to bring a global and multicultural perspective to my work and team.In my previous role as a Lead Senior Data Scientist at Amazon, I managed a team of data scientists and economists focusing on forecasting, anomaly detection, and graph analytics for Global Talent Management products and programs. I was responsible for defining the vision, strategy, and roadmap for data science projects, and for delivering high-quality and scalable solutions that improved talent management programs and business outcomes. I used my skills in native AWS service architecture design, data science, and data analysis to create and implement robust and reliable models and algorithms that enhanced the accuracy and efficiency of talent management decisions and outcomes.
