Summary
👤
Senior🎓
Top SchoolTianjiao Ding is a research-focused machine learning engineer with 11 years of experience bridging rigorous mathematics and practical systems to solve robustness, efficiency, and unsupervised learning problems. Currently a Research Assistant at UPenn (transferred from JHU) and formerly an Applied Scientist at AWS, she has developed provably robust algorithms for corrupt inputs, state-of-the-art unsupervised clustering on CIFAR/ImageNet, and zero-shot plug-and-play methods that steer LLM and diffusion model behavior via sparse coding of latent activations. Her work includes a first large-scale concept dataset (40,000 concepts, 1.2M context sentences), variational spectral forms enabling linear-time transformers, and efficient 3D reconstruction and motion estimation methods that rival RANSAC at much lower cost. Comfortable in both theory and implementation, she repeatedly turns abstract mathematical guarantees into practical gains for vision and language models. Based in Philadelphia, she blends deep academic training with industry research experience to deliver reproducible, high-impact ML innovations.
