I’m an organic geochemist, specialized in using organic lipids (biomarkers) and their stable isotopic composition to apply and develop biomarker proxies to answer the most
challenging and critical questions in the earth and environmental sciences.

Teaching
๏ Climate Change: Science and Impacts, University of Bristol: Fall 2015
This is a practical and theoretical course designed for new graduate students of the master of science track in climate change science and policy. Within this course students explore the current consensus on the evidence of climate change and the (future) impacts
on natural and human systems. Using global circulation climate model simulation the
students independently conduct research and critically evaluate the impact of anthropogenic climate change. Based on their work students have to write two essays. Particular attention is paid to developing scientific writing skills. 30 students
๏ Tracing and Observing the Earth System. University of Bristol: Fall 2013&14&15
This is a theoretical course designed for graduate students in earth sciences. In this
course students explore the observational and analytical approaches used to trace the
earth and environmental processes that underpin our understanding of the earth’s climate system. Through presenting key-scientific papers and group discussions, the students develop their presentation skills. Within this course I teach the component that focuses on the global carbon cycle during the Phanerozoic and key biomarker proxies. 10
students
๏ Frontiers in Earth Sciences. University of Bristol: Fall 2013&14
This is a theoretical course designed for graduate students in earth sciences. Within this
course students learn to critical examine important topics in the broad field of earth sciences in which either new approaches to existing subdisciplines are emerging or new
fields are being created. The study of each topic comprises an introductory lecture, time
for reading and a short symposium with students discussing different aspects of the topic. Students produce a piece of written work on one of the subjects. Within this course I
teach a component on astronomically forcing of climate during the Plio/Pleistocene. 20
