Ageing is measurable. So is what slows it.

I combine machine learning, human biomarkers and experimental biology to study ageing and evaluate interventions.

    Predicting and finding geroprotective compounds through modulating conserved longevity-associated aging modules

    Science Advances

    A machine-learning approach that predicts geroprotective compounds by targeting conserved longevity-associated modules, then validates the predictions experimentally.

    2026HumansPreprint

    Acute and 6-month vascular effects of a multi-component nutritional supplement: a randomised controlled trial

    SSRN

    A randomised, double-blind, placebo-controlled trial measuring what a multi-ingredient supplement does to blood vessel function, immediately and after six months.

    2025thought leadership

    Reporting quality, effect sizes, and biases for aging interventions: a methodological appraisal of the DrugAge database

    npj Aging

    A methodological audit of the DrugAge database, checking how well ageing-intervention studies report their results and how large the effects really are.

    2025Omics

    DoliClock: a lipid-based aging clock reveals accelerated aging in neurological disorders

    Aging

    An ageing clock built from brain lipid measurements. It estimates biological age from postmortem brain samples and finds accelerated ageing in neurological disease.

    2025Model organismsPreprint

    Rescuing healthspan in obese, aged mice: a comparison between multi-ingredient nutraceuticals and senolytic interventions

    Preprints.org

    Two strategies compared head to head in old, obese mice: a multi-ingredient supplement and drugs that clear senescent cells.

    2024Databases

    Human Ageing Genomic Resources: updates on key databases in ageing research

    Nucleic Acids Research

    An update on the family of open databases that ageing researchers use to look up genes, compounds and species data, including DrugAge.

    2024Omics

    A concerted increase in readthrough and intron retention drives transposon expression during aging and senescence

    eLife

    Apparent activation of jumping genes with age is largely explained by how RNA is read and spliced, not by the transposons themselves waking up.

    2024thought leadership

    The impact of short-lived controls on the interpretation of lifespan experiments and progress in geroscience — through the lens of the "900-day rule"

    Ageing Research Reviews

    When control animals die early, a treatment can look life-extending when it is not. The paper sets out how short-lived controls distort the lifespan literature.

    2024in vitro

    Promising effects of novel supplement formulas in preventing skin aging in 3D human keratinocytes

    Nutrients

    Supplement formulations tested on three-dimensional human skin cell models to see whether they slow markers of skin ageing.

  4. 2023
    2023Humans

    Alpha-ketoglutarate supplementation and biological age in middle-aged adults (ABLE) — intervention study protocol

    GeroScience

    The published protocol for a randomised, double-blind, placebo-controlled trial testing alpha-ketoglutarate against epigenetic and functional measures of ageing.

  5. 2022
    2022Model organisms

    A small-molecule Psora-4 acts as a caloric restriction mimetic to promote longevity in C. elegans

    GeroScience

    A compound that reproduces some effects of eating less, extending lifespan in the nematode C. elegans.

  6. 2021
    2021Humans

    Rejuvant, a potential life-extending compound formulation with alpha-ketoglutarate and vitamins, conferred an average 8 year reduction in biological aging

    Aging

    Users of an alpha-ketoglutarate and vitamin formulation showed, on average, an eight-year lower biological age on a DNA methylation test after roughly seven months.

    2020Model organisms

    Lifespan and healthspan benefits of exogenous H2S in C. elegans are independent from effects downstream of eat-2 mutation

    npj Aging and Mechanisms of Disease

    Hydrogen sulfide extends life and health in worms through a route separate from the classic dietary-restriction mutation.

    2020Databases

    SynergyAge, a curated database for synergistic and antagonistic interactions of longevity-associated genes

    Scientific Data

    An open database of what happens when two longevity genes are altered together: the effects can add up, cancel out, or reverse.

    2019Model organisms

    Metabolic stress is a primary pathogenic event in transgenic Caenorhabditis elegans expressing pan-neuronal human amyloid beta

    eLife

    In worms carrying human amyloid beta in their neurons, metabolic stress appears first, before the damage usually blamed on the protein itself.

    2018Model organisms

    Drug synergy slows aging and improves healthspan through IGF and SREBP lipid signaling

    Developmental Cell

    Combining drugs that act on different ageing pathways slows ageing more than either drug alone, working through IGF and lipid signalling.
