Jennifer K. Hellmann

Jennifer K. Hellmann studies how environmental stressors such as predation risk, social conditions, and temperature shape animal behavior, particularly in fish like the threespined stickleback and ocellated wrasse. A major focus is transgenerational plasticity, meaning how a parent's experiences (such as facing predators or social isolation) can influence the behavior and physiology of their offspring, even across multiple generations. Her work combines behavioral experiments with topics like reproductive choice, parental care, and epigenetics (how gene activity can be influenced by experience without changing the underlying DNA sequence).

Publication output has grown over the last decade, rising from around 3-6 papers per year earlier on to 6-8 per year most recently, indicating a steady or slightly increasing pace of research activity.
