About me

I am a Software Developer at Oracle, working in the Java Platform Group.

Background

Until very recently, I was a Researcher Fellow at The University of Manchester where I worked on how to make computer programs fast by harnessing the power of specialized hardware like Graphics Processing Units (GPUs) and Field Programmable Gate Arrays (FPGAs). I also led the development of TornadoVM, a Java framework that automatically allows Java programs to utilize this hardware for a massive speed boost. My background is compilers, Just In Time compilation, managed runtime systems and GPUs.

Past Collaborations

I have worked a few EU projects, such as AERO European Project for porting TornadoVM to ARM and RISC-V based computing systems with hardware accelerators. Besides, I collaborated with the GAIA project (under the European Space Agency ESA) to help accelerating Java HPC workloads on GPUs using the TornadoVM software stack. I have also worked and collaborated with Intel to bring oneAPI into the TornadoVM framework to perform optimisations for Intel compute architectures (xPUs).

Public Speaking and Standarization

I do public speaking about my previous research at the University of Manchester and software engineering topics. I have presented at several academic and Industry conferences, including JVMLS, QCon, Devoxx, JavaZone, JAX, and Java User Groups, such as NYJavaSIG.

I am also an Intel oneAPI Innovator, and I participate in the Level Zero Community Forum Hardware Group, and in the oneAPI Language Group to help shaping the evolution of oneAPI for managed runtime programming languages. From January 2025, I also participate as an external member in the RISC-V J Extension Group.

Education

I obtained my PhD at The University of Edinburgh on Accelerating Interpreted Programming Languages on GPUs with Just-In-Time and Runtime Optimisations. I extended the Graal JIT compiler and the Partial Evaluator to allow programmers to automatically execute Java, R and Ruby programs on GPUs via OpenCL.

Before doing the PhD, I obtained my Bachelor’s and Master’s degrees in Computer Science at The University of La Laguna (Tenerife, Spain). In my Master’s project, I contributed to the development of the accULL compiler, the first open-source compiler’s implementation for the OpenACC standard, under the supervision of Dr Ruyman Reyes and Dr Francisco de Sande.

Industry

Additionally, I have also worked as an intern at Oracle Labs and CERN, implementing compilers and evaluating parallel programming techniques for multi-core systems.
