John P. Morrissey (biologist)

John P. Morrissey is a biologist specializing in fungal biology and stress response. He is currently a lecturer at University College Cork (UCC) in Ireland. His research focuses on understanding how microorganisms, particularly fungi, respond to and tolerate environmental stresses such as oxidative stress, osmotic stress, and nutrient limitation. A key area of his research involves investigating the molecular mechanisms underlying stress adaptation in industrially relevant fungi, particularly Aspergillus species and yeasts like Saccharomyces cerevisiae. Understanding these mechanisms has potential applications in improving the efficiency and robustness of fungal strains used in various biotechnological processes, including the production of biofuels, enzymes, and other valuable products. His work often involves genetic, molecular, and physiological approaches to elucidate the roles of specific genes and pathways in stress resistance.
