Rockstar🎓
Top SchoolMario Melara is a workflow systems and bioinformatics data engineer with 11 years of experience building scalable, reproducible pipelines for national labs and large-scale scientific computing centers. Based at Berkeley Lab and previously at NERSC, he focuses on distributed computing, DevOps, and making genomic data FAIR through the JGI Analysis Workflow Service and the ESS-DIVE infrastructure. He has deep hands-on experience with HPC package management—contributing bioinformatics support to the widely used Spack project (e.g., samtools, bowtie2)—and has supported CI/CD and pipeline operations across multi‑lab collaborations. Mario’s background in molecular biology and early lab roles gives him a practical appreciation for experimental constraints, which he pairs with systems engineering to accelerate biological discovery.
