CV summary (Sep 2026)

Educated at the HPC&A group at Universitat Jaume I (UJI) under the supervision of Prof. Rafael Mayo, I defended my Ph.D. Thesis in 2018. This stage of my scientific career was supported by the FPI fellowship from the Generalitat Valenciana (Val I+D) program. My doctoral work involved joint collaborations with the PMRS group led by Dr. Pavan Balaji at Argonne National Laboratory (ANL, funded by the USA Dept. of Energy) and the AccelCom for HPC Team led by Dr. Antonio Peña at the Barcelona Supercomputing Center (BSC, supported by the H2020 EuroLab-4-HPC program).

After my Ph.D., I continued my scientific career at the GAP group at Universitat Politècnica de València (UPV) as a postdoctoral researcher funded by the Juan de la Cierva (JdC) program, the RED-SEA European project, and the APOSTD 2023 program (GV). Currently, I am an Assistant Professor (Profesor Ayudante Doctor) at the Department of Computer Engineering (DISCA) at UPV.

During this period, I have built and led a research team composed of postdoctoral researchers, Ph.D. students, and master's students. Within the team, I lead three primary research lines:

• Code Auto-generation

• LLMs4HPC & HPC4LLMs (Large Language Models for High-Performance Computing and HPC for LLMs)

• RISC-V Architectures & Low-Power Processors

My work has been disseminated in 30 publications in international journals indexed with JCR-WOS impact factors Q1 (x10) and Q2 (x18); 37 peer-reviewed research papers in international conferences indexed the GII-GRIN-SCIE index; and 20 in national conferences. I received the best paper award at ENERGY14 and PPAM 2026. Google Scholar reports 883 citations to my work and H and i10 indexes of 16 and 29, respectively. Following the Open Science principles, 20 JCR papers are published under an open-access policy, and preprint versions are available. The software is at github.com/adcastel.

The active collaborations led to the participation in 2 R&D projects in USA, 6 National projects (Plan Nacional I+D+I), 6 European H2020 projects, four industry projects, and 13 local projects (three as P.I.). Moreover, the international contacts resulted in participating in the program committees of international conferences such as AsHES (also organizing committee), CGO, Euro-Par, HeteroPar (also organizing committee), CLUSTER, or ICPP. I am a reviewer for international journals such as Journal of Supercomputing, Parallel Computing, Journal of Parallel and Distributed Computing, or Transactions on Architecture and Code Optimization. I am also co-guest editor of the special issue of the HeteroPar24. I have also participated as a project reviewer for the Croatian Science Foundation. I am a member of the SARTECO and SCIE and a member of the international networks HiPEAC and ACM.
