Job Description
The University of Twente, Faculty ITC, wishes to increase the number of women in the faculty to have a more balanced staff profile. During all phases of the selection process, we will therefore prioritize selecting women who fit the profile.
Your challenge
The Dutch government, through the Ministry of Education, Culture and Science, has responded to the current global environmental challenges by establishing sector plan positions in critical scientific domains. At the Department of Environmental Resources, one of our activities is to address these challenges by developing and applying Geostatistical models for bridging knowledge gaps, data scarcity and uncertainty gaps, and governance gaps related to monitoring the environment on which humans depend.
A part of this is
spatial statistics of sensor data integration for nature-inclusive solutions
for
monitoring stress and diseases of tree crops
.
Tree crops like cocoa, apart from their direct economic functions for smallholder farmers, sit at the intersection of many beneficial ecological functions (including carbon sequestration and cultural identity). However, these functions are threatened by environmental stressors and diseases such as Cocoa Swollen Shoot Virus (CSSV) disease, which depend on the complex web of interactions between and within above-ground and below-ground biotic and abiotic factors. The prevailing data and methodological gaps that have perpetuated knowledge gaps in the spatial and spatiotemporal patterns of tree disease, and the widened governance gaps of farms, have motivated this topic.
You will develop spatial statistical methods to integrate ground-based IoT sensor data, remote sensing data, and in-situ data for mapping the spatial trends of cocoa diseases. You will be involved in setting up an IoT sensor network in cocoa farms in Ghana. You are expected to address data integration challenges, including (1)
spatial misalignment of networks
, (2)
temporal misalignments
of observations, (2)
probabilistic or likelihood misalignments
, and (3)
data quality issues,
such as
uncertainties
in measurements,
sparsity of network coverage
resulting in
small N
,
missing data
resulting from malfunction of sensors, and
outliers
. For the purposes of evaluating model transferability, you will make a comparison with other economically important tree crops in food forests in the Netherlands. You will design a measurement setup for cocoa trees and review the wide range of applications of IoT sensors, their uncertainties, and the observable variables above and below ground that are important for predicting tree crop diseases and stresses. You will also explore simulation scenarios to evaluate the impact of indigenous and formal farming management practices on plant diseases.
Your profile
An MSc related to geoinformation science and earth observation, spatial and spatiotemporal modelling, spatial statistics, and/or machine learning. You enjoy applying these modelling skills to analyse and explain interactions within environmental and ecological systems
Able to handle and integrate multi-temporal and multi-spatial data from multiple sources, including earth observation data, IoT-based sensor data, and in situ data
Comfortable with programming or scripting in Python or R for data analysis and for bringing your models to the data
Good communication skills and an excellent command of the English language
Enjoy engaging in team science with project and societal partners
Willing to travel and to collect data in the field; familiarity with cocoa farming in Ghana is an advantage given the required interaction with local managers.
Motivated to contribute to knowledge dissemination and uptake activities for societal partners while also embracing Open Science and FAIR data principles
A passion for education in an international classroom.
Interested in developing educational materials and teaching topics related to spatial modelling and understanding interactions in environmental systems.
A dedicated and considerate advisor for MSc students.
Our offer
An inspiring multidisciplinary, international and academic environment. The university offers a dynamic ecosystem with enthusiastic colleagues in which internationalization is an important part of the strategic agenda
Full-time position for four years with a qualifier after 6 – 9 months
A professional and personal development programme within Twente Graduate School
Gross monthly salary of € 3,204.00 in the first year, which increases to € 4,051.00 in the fourth year
A holiday allowance of 8% of the gross annual salary and a year-end bonus of 8.3%
Excellent support for research and facilities for professional and personal development
A solid pension scheme
A total of 41 holiday days per year in the case of full-time employment
Excellent working conditions, an exciting scientific environment, and a green and lively campus.

About The Department
Environmental Resources are crucial to maintaining the well-being of societies. Sustainable management of these natural resources balances the needs of people and the environment. It avoids the depletion, degradation, and destruction of ecosystems, prevents biodiversity loss and soil erosion, and mitigates the impacts of climate change. Our research, education, and partnerships empower society to effectively use insights from geo-information and Earth observation technologies to sustainably manage the environment. The outcome is an increased understanding of the processes that affect the availability, stability, quality, and sustainability of natural resources, enabling their preservation, sustainable use, development, or restoration. Our academic staff, PhD candidates, and MSc students focus on developing both the means and the measurements essential for monitoring
About The Organisation
The Faculty of Geo-Information Science and Earth Observation (ITC) provides international postgraduate education, research and project services in the field of geo-information science and earth observation. Our mission is capacity development, where we apply, share and facilitate the effective use of geo-information and earth observation knowledge and tools for tackling global wicked problems. Our purpose is to enable our many partners around the world to track and trace the impact – and the shifting causes and frontiers – of today’s global challenges. Our vision is of a world in which researchers, educators, and students collaborate across disciplinary and geographic divides with governmental and non-governmental organisations, institutes, businesses, and local populations to surmount today’s complex global challenges and to contribute to sustainable, fair, and digital societies.
