Research interests

Already from the beginning of my scientific career, research on marine environments have been the lead focus in my biological studies. My PhD on fish ecology are mainly focussed on explaining shifts in population dynamics in all trophic levels in both the present and the past. Not only by analysing shifts in fish populations, determine physiological requirements in different life stages of important key fish species (lower- and higher trophic levels) is important in order to predict how sea food webs will chance due to (anthropogenic-) changes in the Wadden Sea. By combining the analysis of historical data, the collection of field work data and the inventory of potential important fish habitats in the Wadden Sea might tell us more about how fish population on larger world wide scale will change. These large impact ecological analysis  on marine ecology which might be extrapolated to a worldly scale is very appealing to me.

WADfilm: De vissentrek naar de rijke Waddenzee
Nu het lente is en het water opwarmt, komen er allerlei vissen naar de voedselrijke Waddenzee. Ook komen de larven van schol, bot en haring op dit moment met miljoenen tegelijk naar binnen op zoek naar kleine schelpjes en wormen en andere kleine…
