Junxiong Wang

I am applying for a research position focused on language models and systems. Please reach out if you think I am a good candidate!

Currently, I am working on the intersection of language models and systems.

Efficient architectures (i.e., linear RNN models) and systems for modeling long sequence.
Fast video frame retrieval with adaptive indexing using LLMs.

Previously, I worked on large-scale data processing systems and distributed computing systems.

I am incredibly fortunate to have worked on

Entity retrieval in the Siri Information Intelligence Knowledge Platform at Apple.
Automatic indexing for big data systems in the Data Systems Group at Microsoft Research.
