Loïc Lannelongue

Loïc Lannelongue is a Senior Research Associate at the University of Cambridge, affiliated with the Cardiovascular Epidemiology Unit in the Department of Public Health and Primary Care (School of Clinical Medicine) and the VPD Heart and Lung Research Institute. He serves as a Postdoctoral Associate at Jesus College and is a visiting scientist at EMBL-EBI, leading research at the critical intersection of sustainable computing and biomedical data science.

His academic foundation includes:

• BSc from ENSAE Paris (2017)
• MSc (Diplôme d’Ingénieur) from ENSAE Paris (2018), majoring in mathematics and statistics with minors in theoretical physics and economics
• MSc in Statistics and Machine Learning from the University of Oxford (2018)
• PhD in Health Data Science from the University of Cambridge (2022), supervised by Prof Michael Inouye under MRC-DTP funding

Lannelongue’s pioneering work centers on environmentally sustainable computational science, developing tools like the Green Algorithms calculator to quantify and reduce computing’s carbon footprint. His research bridges hardware infrastructure limitations with scientific practice, focusing on AI ethics, carbon accounting methodologies, and policy frameworks like the GREENER Principles. Concurrently, he integrates machine learning with genomics and medical imaging to decode cardiovascular disease mechanisms, exemplified by his Nature-published multi-omic trait atlas.

His publication portfolio reveals a decisive shift toward sustainability metrics in computational research, with 2023 marking a peak in high-impact policy-oriented work (Nature journals, Heidelberg Agreement). Key trends include standardizing carbon footprint methodologies, advocating for green procurement in research funding, and translating environmental impact data into actionable researcher guidelines through the Green DiSC certification.

Accolades recognizing his dual impact:

• Susannah Boddie Impact of the Year Award (Health Data Research UK, 2024) for sustainability leadership
• Software Sustainability Institute Fellowship (2023)
• Cambridge University Sport’s Outstanding Contribution Award (2022)

As an educator, he supervises Computer Science tripos courses in statistics, AI, and bioinformatics while mentoring through the Green Algorithms Initiative. His research is supported by MRC-DTP funding during his PhD and ongoing institutional backing for the Lannelongue Group, which collaborates with European funders to embed sustainability criteria in grant frameworks.

He directs the Lannelongue Group—a hub for Environmentally Sustainable Computational Science—managing the Green Algorithms Initiative (open-source carbon calculators), Green DiSC certification scheme, and ESCS Community. The group’s work bridges hardware engineers and domain scientists to operationalize sustainability, evidenced by tools adopted globally and policy agreements like the Heidelberg Agreement signed by major European research funders.
