Hello, I’m Nicole A. Dimitriou. I’m a data trainer and machine learning engineer with over 10 years of experience in complex research, linguistic auditing, and forensic data verification. I thrive in high-stakes environments and am skilled at ensuring data integrity and ethical alignment across demanding projects.
Specializing in identifying systemic bottlenecks and implementing single-point-of-contact workflows, I optimize project efficiency and accuracy. My experience spans forensic genealogy, crisis intervention, and diverse data-rich domains, where I translate technical requirements into practical, rigorous processes.

- Client Profile & Research Scope
Adoptee: Adult male (personal friend of researcher).
Birth: November 1968, Arlington Hospital, Arlington, Virginia.
Adoption Type: Closed/sealed (Virginia Code § 63.2-1241; no original birth certificate access).
Initial Clues: Birth month/year, city, and hospital only—no parental names, relatives, or additional records.
Objective: Identify biological parents and enable contact (with consent).
Researcher Background: Complete beginner; self-taught through this case. - Research Challenges
Legal Barriers: Sealed Virginia adoption records.
Paternal Complexity: Grandfather described as a “ladies’ man” with multiple wives and partners; half-aunt estranged from family. No official record of child born to paternal grandparents together (deceptive or undocumented birth).
Maternal Secrets: Grandmother’s undisclosed affair; biological mother raised believing her mother’s husband was her father (NPE); unaware of half-sibling. - Research Log & Methods
Step-by-Step Process:
Executive Summary
This case documents the researcher’s first closed adoption reunion, achieved with no prior genealogy experience. Starting with minimal clues (birthdate, city, hospital), DNA multi-testing and uploads across five platforms identified biological parents, revealed two non-paternity events (NPEs), and facilitated a positive reunion. The process adheres to the Genealogical Proof Standard (GPS) and demonstrates scalable methods used in seven subsequent cases.
Key Outcomes:
Biological mother contacted (warm reception).
Biological father named by mother; paternal grandparents definitively confirmed via DNA mapping despite no recorded child.
Immediate DNA Testing (Strategic for Beginner): Adoptee tested autosomal DNA at 23andMe, MyHeritage, and AncestryDNA.
Advanced Uploads (Maximize Matches): Raw results uploaded to GEDmatch (for chromosome clustering/utility phasing) and FamilyTreeDNA (FTDNA) (for Y-DNA/mtDNA/autosomal refinement). Total: 5 platforms.
Paternal Line Breakthrough:
Half-aunt match (daughter of paternal grandfather via prior relationship).
Interview (despite estrangement): Confirmed grandfather’s promiscuous history, providing surname/context clues.
DNA Mapping: Chromosome clusters definitively confirmed paternal grandparents—overrode lack of records.
Maternal Line Breakthrough:
Half-brother to biological mother match.
Traced shared father (grandmother’s affair partner); biological mother lifelong unaware of sibling or true paternity.
Verification & Disclosure: Biological mother named bio father. Researcher sensitively disclosed NPE and half-sibling connection.
