Researcher

Olga Vrousgou

Olga Vrousgou is a researcher whose work spans biomedical data resources, distributed ledgers and language-model training. Her publications cover ontology tools, Open Targets and the NHGRI-EBI GWAS Catalog. She later coauthored CCF and IA-CCF papers, studied contextual bandits with feedback graphs, and coauthored AgentInstruct, whose synthetic data was used to produce Orca-3. Her last known role was Senior Software Engineer at Microsoft Research in January 2024, when she wrote a guide to custom models in AutoGen.

Timeline

  1. 2015

    A comparative genomics poster

    In 2015, she coauthors the poster “Large-scale modular comparative genomics: the Grid approach” with Fotis Psomopoulos and Pericles Mitkas. It is presented at the 23rd Annual International Conference on Intelligent Systems for Molecular Biology.

  2. 2016

    Ontology service and Open Targets

    In 2016, she coauthors a paper on biomedical ontology evolution in the EMBL-EBI Ontology Lookup Service with Tony Burdett, Helen Parkinson and Simon Jupp; it appears in the EDBT/ICDT 2016 joint conference workshops. Also in 2016, she coauthors the Open Targets platform paper, which describes a data integration and visualization platform that links drug targets with diseases; her affiliations are Open Targets and the European Bioinformatics Institute (EMBL-EBI).

  3. 2018

    The NHGRI-EBI GWAS Catalog

    In 2018, she coauthors the Nucleic Acids Research paper on the NHGRI-EBI GWAS Catalog. As of September 2018, the Catalog contains 5,687 GWAS and 71,673 variant-trait associations from 3,567 publications.

  4. April 2019

    CCF for confidential blockchains

    In April 2019, she coauthors Microsoft Research report MSR-TR-2019-16 with Mark Russinovich and Miguel Castro. The report presents CCF, a framework for building permissioned confidential blockchains.

  5. 2020

    Open Targets Genetics

    In 2020, she coauthors the Open Targets Genetics paper. The open-access resource aggregates human GWAS and functional genomics data to connect GWAS-associated loci and variants with likely causal genes.

  6. April 2022

    IA-CCF and accountable ledgers

    In April 2022, she coauthors IA-CCF, a permissioned ledger system that can assign blame to members who operate misbehaving replicas. Her coauthors include Alex Shamis, Peter Pietzuch, Burcu Canakci, Miguel Castro and Mark Russinovich.

  7. 2023

    Contextual bandits with feedback graphs

    In February 2023, she coauthors “Practical Contextual Bandits with Feedback Graphs” with Mengxiao Zhang, Yuheng Zhang, Haipeng Luo and Paul Mineiro. The paper reduces contextual bandits with feedback graphs to regression, and its algorithms achieve established minimax rates with practical computation.

  8. 2024

    AutoGen and AgentInstruct

    Her last known role is Senior Software Engineer at Microsoft Research in January 2024, when she writes a guide to custom-model support in AutoGen. In July 2024, she coauthors “AgentInstruct: Toward Generative Teaching with Agentic Flows,” an agentic framework for creating synthetic post-training data; the paper appears in the Orca project’s publications list. Post-training Mistral-7b on the data yields Orca-3, which improves on Mistral-7b-Instruct across many benchmarks.

From OpenAlex, as of 21 October 2026.

  1. Among employers with 30+ full-time cases, OpenAI leads primary technical role H-1B pay at $310,000, and Amazon, Google and Microsoft file 57% of all casesIncludes Microsoft. Across 440,669 certified US H-1B filings from 44 employers (FY2020–FY2026), OpenAI leads primary technical role base pay at $310,000 and xAI leads overall base pay at $290,000.
  2. Google had the most people shaping AI every year from 2014 to 2025Includes Microsoft. Our estimates of which organizations employed the most people shaping AI each year from 1955 to 2025, tracing the shift from university labs to companies.
  3. The company share of AI researchers’ top papers was 31% in 2020–2024 and 8% in 1970–1974Includes Microsoft. We estimate where the people shaping AI worked when their most-cited papers appeared: the company share was 31% in 2020–2024 and 8% in 1970–1974, and Google led all organizations in 2020–2024.
  4. Google has the highest combined h-index among AI organizationsIncludes Microsoft. We estimate that Google holds the highest combined h-index at 8,016, while universities account for 73% of the deduplicated total across AI organizations.
