About

PhD and OpSIS

Ran Ding received his Ph.D. in EE from the University of Washington (UW), Seattle in 2014. With support from Intel, his Ph.D. research contributed to the creation of an open-access foundry platform OpSISNature article, which made silicon photonics technology accessible to more than 150 research and industry institutions. For example, researchers at CalTech and MIT used chips fabricated at OpSIS for cutting-edge research in 3D LiDAR sensing, quantum computing, and deep learning computation acceleration.

Representative work:

Elenion

During his PhD, Ran co-founded a fabless (Design-as-a-Service) startup commercializing silicon photonics technology. The startup was later acquired and rebrandedOVUM article as Elenion, where he continued to lead a 15-person core technical group and delivered the companies first commercial productIMRA in 2017.

AWS SageMaker Algorithms Group and AWS AI Labs

Ran then applied his experience in numerical methods and simulations to the area of machine learning and joined Amazon AI’s SageMaker Algorithm Group to research on inifinitely scalable machine learning algorithms and platforms. At SageMaker Algorithm, his main focus was neural variation inference and its applications in Natural Language Processing (NLP)AWS blog, webinar. Later on, he worked in AWS AI Labs and led the design and implementation of core components of a to-be-launched new AWS Service.

Ran’s main interests in machine learning include natural language processing (NLP) (language modeling, topic models, semantic matching, text classification, etc), deep generative models (VAE, GAN, adversarially regularized autoencoders), and learning methods (weak supervision, transfer learning, meta/few-shot learning, domain adaptation).

Ran currently holds 9 US patents and has authored and co-authored more than 80 peer-reviewed academic papersGoogle Scholar.
