My experience spans technical AI leadership with expertise in founding, growing and managing ML engineering, science and product teams. My work involves research and industry-wide practical applications related to the fields of machine learning, natural language processing (NLP), computer vision, data mining and computational decipherment (cracking codes with computers). This has led to scientific advances and industry-wide innovations in conversational AI, on-device machine learning for IoT devices, large-scale unsupervised and semi-supervised methods and their applications to structured prediction problems in NLP, image recognition, information extraction, multi-modal learning for language/vision, user modeling in social media, graph optimization algorithms for summarizing noisy data, computational decipherment and computational advertising.
