Dr. Alessio Rovere, PhD – Junior group leader


Dr. Alessio Rovere is the leader of the group. Alessio has a degree in environmental sciences from the University of Genoa, Italy, and a PhD in marine sciences at the same University. He worked as a visiting scientist in several Universities abroad and he did a two-years postdoc at Lamont Doherty Earth Observatory, Columbia University, NY, where he still holds a position as adjunct research scientist.

Alessio is a field geologist who uses GPS and GIS technologies to understand past sea level changes. In his research, he collaborates with Earth modelers to understand the role of isostatic and tectonic (e.g. dynamic topography) processes that cause post-depositional displacement of the sea level markers observed in the field. Alessio has also a broader interest in the application of new field techniques (such as Unmanned Aerial Vehicles) and GIS analyses to investigate environmental issues, such as habitat mapping or coastal erosion and extreme wave events. Alessio’s research focuses on past interglacials. These periods are of particular interest for the scientific community (and society at large) as they provide us with natural experiments involving a climate system as warm or slightly warmer than today.  Of particular interest is the degree to which relatively small perturbations to climate variables such as atmospheric temperature, solar heating (insolation), or CO2 can lead to polar ice volume and sea level changes.

Dr. Daniel Harris, PhD – Postdoctoral researcher

DSCN0519Daniel is a coastal geomorphologist who focuses on the morphodynamics of coastal and coral reef systems, or more specifically, the nature of change in coastal geomorphology and the processes responsible for driving such change. This research is conducted on multiple temporal and spatial scales from short-term surf zone processes to the reconstruction of paleo sea levels and coral reef evolution. A major strength of Daniel’s research is its multidisciplinary nature, encompassing elements of surf science, beach morphodynamics, and marine geology in combination with effective and novel use of GIS analysis, hydrographic and topographic surveying, high-resolution surf zone measurement, and computer modelling of hydrodynamic processes and geomorphic change. The ultimate aim of Daniel’s research is to produce holistic models of coastal response to environmental conditions in order to better inform management and planning of coastal systems and communities.

Before coming to Bremen Daniel completed his PhD at the University of Sydney in 2013 in Coral Reef Morphodynamics and was a Lecturer in Marine Science for the University of Sydney. He grew up on the New South Wales coast of Australia, he is am an ex-life saver, a surfer, and he has a passion and admiration for beaches, reefs, surf, and the ocean.

Thomas Lorscheid, MSc – PhD student

DSC_1338Thomas achieved his M. Sc. in geosciences from the University of Bonn in 2013. His research focussed on the description of the sedimentological and tectonic evolution of an area in the southern Pyrenees, in France. After working one year as teaching assistant at University of Bonn, he started his PhD at MARUM in October 2014.
Thomas’s research encompasses paleo shorelines from the last interglacial (MIS 5e), in particular for which concerns their description and interpretation of the paleo sea level elevation in order to reconstruct the extent of past ice sheets. Thomas is conducting fieldwork in the Mediterranean and will soon start fieldwork in other key sites. In each site, he will apply modern GPS and GIS techniques to measure and evaluate different relative sea level markers, and will contribute to the build up of a global sea level database for MIS 5e.Institutional page MARUM







Alexander Janßen, MSc – Research assistant

Alexander is a research assistant in the working group since November 2015. Alexander accomplished his M.Sc. in geosciences at the University of Bremen in 2015. In his masters thesis he focused on the sedimentological composition and evolution of an uninhabited reef island in the Spermonde Archipelago in Indonesia. Alexander is a coastal geomorphologist, with expertise in Geographic Information Systems applied to the study of paleo shorelines.

Dr. Eng. Elisa Casella, PhD, postdoctoral researcher (part time)


Dr. Eng. Elisa Casella has a degree cum laude in Environmental Engineering, Natural and Industrial Risk Management from the University of Genoa, Italy and two legal PhD titles, one in Methods and Technologies for Environmental Monitoring from the University of Basilicata, Italy and one in Science de l’Univers from the University of Toulon,France. She did a first postdoc at the Department of Computer and System Sciences, University of Genoa, Italy and a second postdoc, in the framework of MIRAMAR project, at the Department for the study of Territory, Environment and Life, University of Genoa, Italy. Elisa is an environmental engineer who studies coastal changes using post processed data derived from small Remotely Piloted Aircraft System (RPAS) integrated with numerical models. Elisa uses RPAS as platforms for coastal monitoring specifically for geomorphological coastal studies and impact assessment of sea storm events. Previously, during her first postdoc, she studied the impact of local scale physical processes on the biological productivity of the North Western Mediterranean Sea using the Regional Ocean Modeling System (ROMS). During the postdoc she worked with biologists and physicists in different European countries to implement a numerical model to simulate physical and biological processes which, together with satellite-derived data, provide information to the study of the ecology of marine mammals in the North Western Mediterranean. During the same period Elisa did operative activity at CIMA Research Foundation Operations Centre for the National Department of Civil Protection (Italy). As environmental engineer she provided technical support activities to civil protection decision-makers for the monitoring and forecasting system on hydrological risk and forest fires risk through a management and a conform surveillance of the data stream. Elisa had a central role in the project MIRAMAR (Innovative Methodologies for Coastal Environmental Monitoring and Analysis), funded by the European Social Fund. She is developing solutions to integrate RPAS data with numerical models to reach a new view on coastal change processes.


Dr. Matteo Vacchi, PhD, postdoctoral researcher, CEREGE, Universite Aix Marseille, France

Matteo will visit ZMT and MARUM during 2015-2016

foto kryftyDr Matteo Vacchi is presently postdoctoral researcher at CNRS-CEREGE in Aix en Provence (France). Matteo has a degree in Geology from the University of Genoa, Italy, and a PhD in Earth Science at the same University. Matteo did a 1-year postdoc at the University of Bologna (italy), where he worked on numerical modeling of coastal processes and has now a 2-years postdoc in the framework of the Labex OT-Med (www.otmed.fr). Matteo is a coastal geologist and his research is mainly focused on holocene sea level changes in the Mediterranean Sea. Matteo collaborates with the sea level and coastal changes group in the application of new field techniques (such as Unmanned Aerial Vehicles) and GIS analyses applied to habitat mapping and definition of mitigation procedures to face coastal erosion and extreme wave events. Matteo’s  present research focuses also on the paleogeographical evolution of Corsica and Sardinia and interaction between the segrasses meadow and the coastal hydrodynamics.
