About Me (徐浩然)

I am a Member of Technical Staff at Microsoft AI SuperIntelligence. I earned my Ph.D. in Computer Science from Johns Hopkins University in 2024, co-advised by Philipp Koehn and Kenton Murray, with the topic of foundational training of large language models, machine translation, and multilinguality.

My recent research explores next-generation AI agents, focusing on the complex reasoning and automated engineering of language models, aiming to build highly capable agents for technical domains. Please find up-to-date list of all my publications on my Google Scholar profile.

I also had good fortune to intern at Microsoft, Meta (Facebook) AI Research and Amazon Alexa AI.
