    About me

    Most of my past and current research focuses on assessing anthropogenic impacts on marine mammals, in particular baleen whales. I am interested in how behavioural changes, caused by human disturbance can influence population dynamics by affecting individual survival and reproduction. Further, I’m interested in how such non-lethal effects can be incorporated into existing management frameworks to aid in conservation. To understand the relationship between behaviour and population dynamics, I have worked in a number of research areas, including behavioural ecology, physiology, bioenergetics and reproductive biology. Apart from whales, I have also done research on sea turtles (movement ecology), sharks (attacks rates), snakes (morphometrics and reproduction) and invertebrates. I have a strong interest in ecological modelling and statistics, in particular time series analyses, spatial analyses, and individual based models.

    Current projects

    Main project: Developing a bioenergetic model for baleen whales to assess population consequences of disturbance

    Study species: Southern right whales, humpback whales, gray whales

    Summary: The aim of this project is to determine how behavioural disturbances on baleen whales can translate into long-term effects on the vital rates (survival and reproduction) and population dynamics of baleen whales. In order to understand this, I am trying to link behaviour to bioenergetics (energy expenditure and acquisition), bioenergetics to health (body condition) and health to vital rates. Understanding these relationships will make it possible to predict population level consequences of disturbance on an individual level.
