Forschungsinteressen
Die Fachgebiete der physikalischen und chemischen Ozeanographie, der mikrobiellen Ökologie und Meeresgeologie bilden das Grundgerüst meiner wissenschaftlichen Arbeiten. Damit untersuche ich den marinen Methankreislauf. Zu meinen Forschungsschwerpunkten gehören: Auswirkungen von Meeresströmungen auf die Methanverteilung und die mikrobielle Oxidation von Methan, zeitliche Einschränkungen von Methananreicherungen und des mikrobiellen Abbaus von Methan, Quantifizierung mikrobieller Methanumsätze im Meer (u.a. mit Hilfe von Transport-Reaktionsmodellen) sowie Labor- und Feldstudien, um Techniken zur Bestimmung der mikrobiellen Umsatzraten des Gases zu evaluieren. Eines meiner wichtigsten wissenschaftlichen Ziele ist es, die Entstehung und den Abbau von Methan in der Wassersäule und den Oberflächensedimenten mithilfe dieses integrierten Ansatzes zu verstehen und das Wissen anzuwenden, um Änderungen des atmosphärischen Methangehalts in der Erdgeschichte zu verstehen.
