Michalis Papadimitriou

Michalis Papadimitriou is a Senior Software Engineer at Neo4j and a Research Fellow at the University of Manchester. His core expertise includes open-source software development, hardware abstractions for high-level programming languages, compiler optimizations for GPU computing, and enabling large language model (LLM) inference on GPUs for the Java Virtual Machine (JVM).
He is focused on advancing high-performance AI and graph computing systems, with particular interest in GPU acceleration for machine learning workloads on the JVM through the TornadoVM framework, and continues to actively maintain the open-source GPULlama3.java project.
Before joining Neo4j, Michalis was a Research Fellow at the University of Manchester, where he contributed to the TornadoVM project as a Staff Software Engineer. Prior to that, he worked across a range of software stacks at Huawei Technologies and contributed to the open-source machine learning compiler Apache TVM while at OctoAI (formerly OctoML), which was later acquired by NVIDIA.
