Giulio Valentino Dalla Riva. Italian and New Zealand citizen, based in Nouméa, New Caledonia.

I'm a Statistics Advisor (Data Systems) at the Pacific Community. I look after PDH .Stat, an SDMX data platform supporting evidence-based work across the Pacific island nations. I lead several AI-for-data-access projects, and I drive the adoption of a Data Governance practice in the division.

I founded and run Baffelan, a boutique data-science consultancy that takes on data-science-for-good projects alongside paid work for organisations that want more from their data than a cookie-cutter answer can give them.

I was Director of Data Innovation at Inverence, where I led a team of around ten people building llull, an AI-integrated platform for data discovery and data understanding deployed at banks, large corporations, and a handful of government institutions, until the product was finally ready for market in September 2025.

Before all that I was a Senior Lecturer in Data Science at the University of Canterbury, where I led the DaRe Science research group, taught data wrangling, statistics, machine learning and ethics, and worked on AI and disinformation.

I trained as a mathematician (PhD Canterbury, MSc Trento). I work in Julia, R, and Python, and I like to put different things together and see what happens when they inevitably explode.

Current roles

  • Statistics Advisor (Data Systems)

    Pacific Community (SPC), Statistics for Development Division

    Nouméa, New Caledonia

    2024-04 – present

    Product owner of PDH .Stat, an SDMX data platform that supports evidence-based work across the Pacific island nations. I lead several AI-for-data-access projects (see Open source). I also drive the adoption of a Data Governance practice in the division and run training initiatives across the region.

  • Founder, Head of Data Science

    Baffelan

    Christchurch, New Zealand (remote)

    2023-01 – present

    A boutique data-science consultancy. Six people at peak across data engineering, data science, and dev-ops; today it scales with the work, mostly me with collaborators brought on per engagement. We take on data-science-for-good projects alongside consulting work for organisations that want more from their data than a cookie-cutter answer can give them.

Past roles

  • Director of Data Innovation

    Led a team of around ten people building llull, an AI-integrated platform for data discovery and understanding, deployed at banks, large corporations, and a handful of government institutions. Set the wider data and AI strategy across forecasting, optimisation, counterfactual analysis and anomaly detection with Bayesian statistics. The engagement concluded in September 2025 when llull was ready for market.

      Led the DaRe Science research group: around twenty people, from undergraduates to PhD students to a few early-career academics. The group published about fifty papers (many without my name on them, by design), gave talks at conferences and broader-audience events, and secured around USD 5 million in grants from the Andrew W. Mellon Foundation, Facebook, the New Zealand Government, and other partners. We worked across academic, industry, government, and grass-roots collaborations. With Te Pūnaha Matatini, contributed to the COVID-19 response that won the 2020 Prime Minister's Science Prize, including a New-Zealand-Government-commissioned platform that monitored medical disinformation online and reported into the Prime Minister's Cabinet. Ran a joint medical-ML team for early detection of post-operative critical issues. Taught data wrangling, ethics, statistics, machine learning, and network analysis.
