Summary
👤
Senior🎓
Top SchoolYifei Sun is a Staff Machine Learning Engineer with 8 years of experience bridging academic rigor and product-focused ML across NLP and computer vision, currently leading AI research for monetization at Meta. Previously a senior applied scientist at Amazon, she has shipped solutions for customer intent classification, off-topic detection, text summarization, fraud detection, and image classification. Her strong theoretical grounding—evidenced by top-tier publications and a Google Scholar profile—stems from a PhD and postdoctoral work on high-dimensional PDEs, uncertainty quantification, and numerical methods that solved problems once thought computationally infeasible. Comfortable moving models from research to production, she pairs leadership experience with hands-on modeling and a knack for applying advanced mathematics to real-world ML challenges. Unusually, her background includes NASA-sponsored stochastic modeling for rocket spray atomization and satellite uncertainty propagation, reflecting a broad appetite for tough, cross-domain problems.
