Research in the Dias lab seeks to understand how the nervous system is impacted by stress or trauma, and how parental legacies of stress or trauma influence offspring by leaving imprints on the parental germline (sperm and egg).
Armed with this understanding, Dias and his team aim to devise therapeutic interventions to ameliorate the effects of stress or trauma in both parental populations and their offspring. To investigate how the biology of an organism and its responsiveness to stress or trauma is influenced by micro- (genome, epigenome and hormones) and macro-environments (ancestral, in utero and post-natal experiences), Dias uses molecular, cellular, genetic, epigenetic, physiological and behavioural approaches. Most of his work uses mice, but generous collaborators have enabled Dias and his team to begin investigating the biological basis of behavioural states and neuropsychiatric disorders in non-human primates and in humans, in multi-generational contexts.
