Our research bridges genomics, physiology, ecotoxicology, behavioral ecology, and evolutionary biology to understand how organisms respond, adapt, and evolve under environmental change.
Our work focuses on three interconnected areas:
Adaptive and evolutionary epigenetics — investigating how epigenetic mechanisms drive adaptation and evolution in populations with low genetic diversity, providing insight into resilience and conservation under genetic bottlenecks.
Long-term and transgenerational effects of environmental stress — exploring how pollutants and other stressors trigger delayed and inherited effects on physiology, behavior, neurodegeneration, and aging, shedding light on the environmental origins of health and disease.
Epigenetics in conservation biology and aquaculture — applying epigenomic tools to monitor population health, guide management strategies, and enhance sustainability in both wild and cultured species.
Using fish models such as the mangrove rivulus (Kryptolebias marmoratus) - the only vertebrate that self-fertilize - and the turquoise killifish (Nothobranchius furzeri) - a short-lived vertebrate ideal for studying aging - we integrates molecular, physiological, and behavioral analyses with field ecology and bioinformatics.
We recently developed an epigenetic clock in the mangrove rivulus, a biomarker linking environmental history, stress, and biological aging. This approach is now being extended to conservation contexts, including endangered species such as the beluga whale and endemic fish from Ecuador, to better understand how environment and time shape life’s resilience.
