Dr. Jan Beutel [mail] [web] [lab]
ETH Zurich

My research interests are centered around wireless and embedded systems - with a focus on applied or "hands-on" topics at the intersection of hard- and software systems. Most recently I am very much interested in design, test and validation methodology for wireless networked embedded systems. PermaSense is an optimal project to test drive our technology research on a real and challenging application - and it allows me to bring my knowledge as a certified alpine guide (UIAGM) to the team as well.

I am fascinated by technology in general and computers and embedded systems in particular. It's my task to support the development of the wireless sensor nodes, from the design to the final deployment. As an engineer, building reliable and efficient software for ultra low-power hardware with crucial resource  constraints is just one of many exciting challenges to face.

Dr. Jérome Faillettaz  [lab]
University of Zurich

I dedicate my research on rupture in natural heterogeneous media, especially on gravity-driven instabilities (i.e., snow avalanches, glacier break-off, landslide, rockfall). I developed pluridisciplinary approach (experimental, analytical, statistical, numerical) to better understand the mechanisms leading to the onset of natural instabilities. The aim of my work is to better assess natural slope stability and to develop efficient early warning methods. I am presently developing methods based on seismic / acoustic emissions measurements to perform real time stability assessment.

Since early 2009 I have been developing, extending and maintaining a software solution for reliable, loss-less data gathering, remote (automated) controlling and energy saving operation for the backbone of sensor networks. To be able to support preferably different aspects of research interests, the so-called BackLog software has been designed to be as flexible as possible. I greatly enjoy working in an interdisciplinary research team being able to combine my engineering with my alpine skills.

Prof. Dr. Christofer Hierold [Opens window for sending emailmail] [web] [lab]
ETH Zurich

Christofer Hierold’s  research is focused on advanced microsystems, the evaluation of new materials for MEMS, and on ultra-low power sensors and systems. We contribute to XSense2 by the development of a novel MEMS acoustic trigger, which mechanically amplifies acoustic events in the rocks with nearly no electrical power consumption, and thus triggers event-driven high resolution, but power hungry sensor systems.

Roland Hohensinn [mail] [web] [lab]
ETH Zurich

My contribution to the project X-Sense 2 will in a first instance focus on a fast and reliable detection of small and rapid movements with GNSS sensors, which are triggered by a MEMS acoustic sensor. Once a movement is detected, a positioning solution with an adequate accuracy shall be provided rapidly, which aims at a fast solution of the so called GNSS phase ambiguities. I really enjoy working on this topic, because it combines my interests in both engineering and scientific tasks.

Romain Jacob [mail] [web] [lab]
ETH Zurich

My research interests are centered around control methods of complex automated systems. I am working on improved management of wireless networks. The objective is to design an event-trigger protocol, which would be highly beneficial for energy savings, while preserving real-time guarantees.

I joined the TIK institute as it offered my the opportunity of applying advanced control and scheduling techniques to tackle real-life problems. Plus, as an outdoor fan, the perspective of having to climb up on top of mountains as part of my job was quite convincing!

Nowadays, there are not many real applications for wireless sensor networks. Permasense is one of the projects, where these networks really bring substantial advantages. In the project, I am responsible for the software that runs on the sensor nodes.

 

Dr. Philippe Limpach [mail] [web] [lab]
ETH Zurich

My research activities focus on geodetic GNSS observations in a wide range of scenarios, as well as on GNSS data processing and the development of GNSS monitoring stations. I am working on strategies and applications for the continuous monitoring of different phenomena in alpine environments with GNSS, including alpine mass movements (e.g. rockglaciers), landslides, glacier behavior, bedrock deformations and long-term tectonic deformations.

Verena Maiwald [mail] [web] [lab]
ETH Zurich

The goal of the Micro- and Nanosystems group's contribution to the X-Sense 2 project is to enable long term autonomous structural monitoring by developing an event driven ultra-low idle power acoustic emission trigger. We hope to achieve a reduced data rate and overall power consumption while preserving the meaningful part of the data. My research activity focuses on the ultra-low idle power electro-mechanical transduction mechanism needed to transform the signal from the mechanical to the electrical domain.

Matthias Meyer [Opens window for sending emailmail] [lab]
ETH Zurich

My research focus is on developing and and enhancing wireless sensor networks on all levels including low-power hardware designs, efficient network management, intelligent data acquisition and data analytics.

With my background in signal processing and embedded systems I am motivated to work on energy savings in WSNs by continuously analyzing its data. The PermaSense project offers a big dataset and a persistent framework. Therefore it is a great environment to work in.

Johann Müller [lab]
University of Zurich

My research focuses on landform and permafrost dynamics in high mountain environments. I use a variety of terrestrial and airborne remote sensing technologies to quantify and assess kinematic and geometric changes in environmental systems controlled by permafrost conditions. Especially terrestrial laserscanning and UAV-based photogrammetry serve as my preferred tools to analyze permafrost creep and rockwall dynamics.     

Michelle Müller [mail] [web] [lab]
ETH Zurich

I am working on a micromechanical structure which amplifies motion in a predefined bandwidth by purely mechanical means. The objective is to combine this amplifier with Verena’s transducer to obtain an ultra-low power acoustic emission detector.

Fabian Neyer [mail]
ETH Zurich

In my PhD project, I deal with different types of datasets describing rock glacier movements. My goal is to combine these measurements in a way such that optimal estimates of surface displacements are obtained. This research topic is embedded in the X-Sense project that I joined in November 2010. Collaborating with people of different research backgrounds but with a common interest in the alpine terrain is a pleasure.

Cosmin Roman [mail] [web] [lab]
ETH Zurich

My current research focus is on developing transducers for autonomous wireless sensor nodes. For that purpose I am looking at transducer design and more exotic sensing mechanisms based on stochastic nonlinear dynamics. At the same time I am considering embedding signal processing into the transducer operation itself and co-designing the transducer and readout circuitry to push the power-resolution envelope towards the fundamental limits imposed by physics.

Tazio Strozzi [mail] [lab]
Gamma Remote Sensing

My research activities include SAR and SAR interferometry for landuse applications (including forest, urban areas, snow cover and hazard mapping) and differential SAR interferometry for subsidence monitoring, glacier motion estimation and landslide surveying. With regard to slope instabilities, my current investigations are focused on the use of very-high resolution satellite SAR data (ALOS PALSAR, TerraSAR-X, Cosmo-SkyMed) and of a terrestrial radar interferometer.

Felix Sutton [mail] [web] [lab]
ETH Zurich 

I'm fascinated by the development and deployment challenges posed by real-world wireless sensor networks. I learned of the PermaSense project through a student semester thesis during Autumn 2010, and have since continued development of a wireless GPS measurement node for geodesy positioning applications.

Prof. Dr. Lothar Thiele    [mail] [web] [lab]
ETH Zurich

The research interests of Lothar Thiele include models, methods and software tools for the design of embedded systems and embedded software. Recently, there has been lots of interest in massively distributed electronic systems such as sensor networks. PermaSense is a great application which allows to test and deploy some of the conceptual and theoretical results that have been developed in the recent years. Besides the hard work that is necessary to build complete systems that are able to function reliably under harsh environmental conditions, we take much pleasure in the cooperation with environmental sciences.

Prof. Dr. Andreas Vieli Opens window for sending email[email] [web] [lab]

University of Zürich

My research is primarily concerned with the dynamics of glaciers, ice sheets and high mountain areas in context of climate change and in particular, the understanding of the involved physical processes and numerical modelling aspects of it. This includes a wide range of processes, environments and time scales and spans from iceberg calving at ocean terminating glaciers in Greenland to the intra-annual flow variations and long-term evolution of rockglaciers in the Swiss Alps.

Samuel Weber   [mail] [web] [lab]
University of Zurich

I am interested in process understanding and quantification of phenomena in mountain permafrost related to climate. The vision for my research is to model and to quantify processes in mountain permafrost (e.g. frost weathering at different depth) combining lab experiments and field measurements in high mountain environments (e.g. acoustic emission, temperature and capacitance for moisture). For this, the combination of geo-science and engineering is very useful and enables field measurements at locations in hardly accessible environments.

It is my pleasure to join X-Sense project, a great platform well linking my job and Ph. D research.  I am glad to work with partners from different  professional fields. My focus is on GPS data processing. Low-cost single-frequency GPS instrument is expected to provide high accuracy, near real time positions to serve the project as one of the displacement monitoring tools. It also creates the possibility to built up early warning system for landslide, rock fall and so on.
