Specialist in Medical Genetics focused on the etiological diagnosis of hereditary conditions, congenital malformations, familial disorders and metabolic diseases. I integrate genomics methods with detailed clinical phenotyping, using frontier computing frameworks for data processing and interpretation. My practice is guided by the principles of #P Medicine and grounded in a humanistic approach and personalist bioethical framework, with a profound respect for the inherent dignity of all human life.

Academic formation & precision-health practice

The integration of genomic methodologies, molecular epidemiology and deep clinical phenotyping establishes evidence-based frameworks for individualized intervention in hereditary and acquired genetic conditions.

🎓

Academic & professional trajectory

Medical degree from Faculdade de Medicina de Petrópolis with degree equivalence certified by Universidade do Porto. Medical Genetics Residency at Instituto Fernandes Figueira (IFF/Fiocruz), a premier reference centre for rare diseases and dysmorphology. Master's in Medicine Research from Instituto Oswaldo Cruz (Fiocruz).

🧭

NP medicine protocols & NGS analysis

Clinical workflows integrating predictive, preventive, personalised and participatory approaches. Analysis and interpretation of NGS data (WES and WGS), phenotype–genotype correlation, evaluation of germline and somatic variants (including VUS), and pharmacogenomic protocols for therapeutic optimisation.

⚖️

Multicenter research & clinical ethics

Collaborative research in genomic association studies, population screening for rare diseases and precision oncology. Interests: systems genetics, polygenic risk scoring (PRS) and NP-BQP computing optimisation. Committed to a personalist bioethical framework, grounded in respect for the inherent dignity of all human life, applied to clinical practice, reproductive counselling and therapeutic decisions.

Research focus

🧬

Doctoral research — UBI · CICS-UBI / RISE-Health

Molecular diagnosis of rare endocrine disease through systematic reanalysis of clinical exomes. Variants of uncertain significance and copy-number variants are reclassified against current criteria, candidate findings are taken to functional validation by RT-PCR and minigene assay, and the confirmed result is returned to the family through genetic counselling.

⧖

Variant interpretation

Reclassification of VUS and CNVs under ACMG/AMP 2015 with the ClinGen SVI refinements and, where a gene has one, the specification of its Variant Curation Expert Panel. In-silico predictors and foundation models are used at their calibrated strength and weighed against population evidence, never in place of it.

🌐

Network medicine

Interactome analysis for mechanisms no single gene explains. Digenic and oligogenic interactions and disease-gene prioritisation are formulated as QUBO and quantum-walk problems, so that candidates are ranked by their position in the network rather than by literature volume alone.

🔬

Rare diseases

Reanalysis of exomes left unsolved on first pass, where the answer is usually already in the data and waiting on a reference update, a re-phenotyping, or a criterion that has since moved. The aim is to shorten the diagnostic odyssey, with particular attention to rare endocrine and syndromic conditions.

🧪

Clinical trials in medical genetics

Design and evidence generation for genetic and rare-disease therapeutics, where cohorts are small and a conventional endpoint may never reach significance. Work runs from biomarker definition and eligibility genotyping through to protocol, with the statistical plan chosen for the size of population that actually exists.

💊

Pharmacogenomics & precision oncology

Translating genotype into a dose and a choice of agent: CPIC-guided prescribing, metaboliser phenotypes and drug-gene interactions on the germline side; actionability tiering of somatic variants on the tumour side. The output is a recommendation a prescriber can act on, with its evidence level stated.

Books — Future’s Medicine Collection

A six-volume work on genomic medicine, written in European Portuguese (pt-PT), taking one continuous path from a biological sample through to a prescribing decision — and on to the computational methods, agentic AI and quantum algorithms the field is moving towards. The volumes are readable in full inside the WorkBench.
