Research Software Engineer | Google Cloud & HPC Scaling | PhD Structural Biology
Senior Research Software Engineer at Zymvol Biomodeling.
Specialized in computational structural biology, holding a Licentiate in Biochemistry (2008) and a Ph.D. in Biophysics (2014). My academic research focused on the structural dynamics of proteins using NMR spectroscopy, bridging wet-lab execution with advanced computational modeling. From 2015 to 2024, I expanded my expertise into software engineering in Python, delivering critical open-source suites including the NIH-funded IDPConformerGenerator and the BioExcel-funded HADDOCK3. I have consistently served as a scientific advisor across numerous collaborations.
In 2024, I transitioned to the private sector to supervise, develop and optimize scalable scientific pipelines, applying my expertise to architect robust software solutions that run seamlessly across HPC clusters and cloud infrastructure.
Throughout my career, I have secured participation in over a dozen funded projects and grants, authored 34 scientific publications and one book chapter, presented 26 posters at international conferences, and dedicated myself to mentoring over 15 students and junior researchers.

I am passionate about understanding the role of protein's flexibility in life and disease: Protein flexibility includes structural adaptation, coordinated multi-domain motions, flexible linkers, disordered regions, and fully disordered proteins. On the other hand, the processes of life and disease include: cell signaling, catalysis, inhibition, activation, coordination, condensation, and many others. Therefore, structural dynamics is intrinsic and necessary to all biomolecules.
Below is a short description of my main research topics. Here, the most relevant articles are highlighted but all my papers are listed in the publications section.
Structural dynamics is vital for cellular processes; hence, protein flexibility governs cell homeostasis in health and disease. In the last two decades, researchers built the basis for understanding intrinsically disordered proteins and we are now able to investigate protein condensation through the lens of structural biology. Specifically, my research focused on understanding how fuzzy binding networks control and describe protein-protein interactions [1, 2], protein liquid-liquid phase separation [3], and how single or multiple mutations result in aberrant condensation in disease.
Working with Dr. Julie Forman-Kay and Dr. Teresa Head-Gordon, we developed a comprehensive software framework to model proteins with high conformational heterogeneity. Our approach integrated experimental data (NMR, SAXS, FRET, etc.), Bayesian inference, machine learning, and statistical sampling incorporating state-of-the-art knowledge of intrinsically disordered proteins (IDPs).
This robust framework paved the way for numerous research projects that continued long after my tenure in Toronto.
At the BioNMR group in Barcelona, we described a new regulatory mechanism for Src Family Kinases (SFK), whose activity is governed by the contraction and expansion of domains via localized phosphorylations on the unstructured domains.
Find here my publications on how flexible linkers and fuzzy binding networks regulate SFK’s activity.
During my Ph.D., we described how the MMP's flexible linker orchestrates the relative movements of MMP's catalytic and hemopexin folded domains by poising them favorably to cleave the triple helical collagen—a process necessary for the metastatic progression of tumor cells [1, 2].
My work was one of the first to combine several NMR techniques, crystallography, and software from the We-NMR consortium to solve a large biochemical unknown and provide models for MMP-1 free, and collagen-bound, in solution. This research was highlighted in the first issue of the paraNMR FP-7 letters, and you can download my Ph.D. thesis from ResearchGate where the MMP-1:Collagen models are presented. I am also the author of the MMP-1 dedicated chapter in the Handbook of Proteolytic Enzymes, 2024.
Antibiotic resistance by pathogenic bacteria is likely today’s top concern in health security. Therefore, identifying alternative routes to destroy infectious bacteria is crucial to develop future disease-control strategies. We demonstrated that TomB antitoxin activity is oxygen dependent, and it actively oxidizes the Hha toxin to reduce the latter’s activity through the oxidation of a conserved cysteine residue [1].
Because of my continuous interest in software architecture and in sharpening best practices in open-source software, I have led the development of (or significantly contributed to) several software suites applied to biophysical sciences.
I highlight my contribution to the HADDOCK3 project as a lead developer from July 2021 to August 2022, when I brought the project from a proof-of-concept to a fully-featured beta version. HADDOCK is the largest biomolecular docking software in academia with thousands of active users worldwide and is part of the three-times European-funded BioExcel project. Plus, to engage and share with the community, I imparted talks on developing open-source software, DevOps best practices, and software architecture.
In the absence of experimental data, computational modeling allows us to have prior knowledge of protein systems and complexes that can guide experimental analysis and project design. Early on during the devastating COVID-19 pandemic, together with colleagues worldwide, we investigated the cross-species transmission capacity of SARS-CoV-2 [1] by modeling the ACE2 receptors of different domestic animal species with the virus’ RBD protein, thus shedding light on the infections reported in farms and zoos and helping predict possible cross-species transmission.
Also, we generated a data set of 242 modeled ACE2 human variants bound to the RBD protein [2]. This data set can boost the design of therapies against SARS-CoV-2 and coronaviruses in general by considering different world populations, and is available openly online.

I guided children at Primary School through a tour that explains the process of pharmacological drug development from the researcher perspective. The tour visits the laboratory of organic synthesis and the laboratory for Drosophila observation. Children are also introduced through a video to the basic concepts in research with mice, always prioritizing animal safety and respect. Laboratory safety rules and sterile conditions are also discussed.
