Research
I am broadly interested in core database systems, synchronization methods, and machine learning systems.
I am currently focused on efficiently implementing, chaining, and optimizing various LLM operators within a streaming processing system, with an emphasis on high-dimensional embedding/vector operators and indexes.
My previous work was to build and evaluate database indexes on persistent memory.
