Postdoc Observations of Aircraft Contrails to Evaluate and Improve Model Predictions

Job description

Contrails are a major contributor to aviation's climate impact: their impact can be mitigated by means of contrail avoidance - deviating aircraft around the regions of the atmosphere where contrails can persist for multiple hours. One of the current limitations to contrail avoidance is uncertainty in the models that we use to predict where contrails are going to persist and how much impact they will have. As a postdoctoral researcher, you will contribute to evaluating and improving contrail prediction models by creating high-quality datasets of contrail observations.

Specifically, you will combine observations from different instruments - such as ground-based imagery, LIDAR measurements, and satellite imagery - to construct datasets that modelers can use to evaluate and improve their predictions.

You will be based in the Operations and Environment section of TU Delft's faculty of Aerospace Engineering, and work closely with Dr. Vincent Meijer, PhD candidates and MSc students.

Job requirements

• A PhD in atmospheric science, remote sensing, aerospace engineering, physics, or a closely related field.
• Strong programming and data-analysis skills, preferably in Python.
• Experience with atmospheric observations, remote sensing, and/or numerical modelling.
• Ability to work with large datasets from multiple sources.
• Understanding of uncertainty analysis and model evlauation.
• Ability to conduct independent research and publish scientific results.
• Good collobration and communication skills in English.
• Experience with contrails, cloud physics, or machine learning is an advantage.

Postdoc IDEE project on 'The Transition from Secondary Education to Higher Education'

Job description

At the TU Delft, we are proud to welcome thousands of students every year within our engineering education. While the students’ transition from high school to our university is an exciting milestone, it also presents significant academic, social, and personal challenges. Our team is interested in how our university supports students during this critical period best, and what successful transitioning actually embodies? In this postdoctoral project, you will investigate student success from an integrated perspective, considering study progress, well-being, and competency development as interconnected actors. Through design-based research, you will develop, implement, and evaluate innovative approaches that help students thrive during their transition to higher education.

The TU Delft Teaching Academy has recognized student transition as a key theme within the Initiative on Innovation in Delft Engineering Education (IDEE). IDEE is a cross-faculty program for innovations and research in engineering education at TU Delft. This project seeks to identify factors that contribute to a successful transition and explore evidence-based practices that support it.

As a postdoctoral researcher, you will focus on one or more of the following:

• Conceptualize what a ‘successful transition’ to higher education entails.
• Identify key factors influencing student success.
• Analyze and evaluate evidence-based practices that support student transition.
• Design and evaluate new practices that support student transition.

You will work as part of the IDEE team on transition, which consists of 20 members from all faculties, as well as educational services at the TU Delft. The supervision team will consist of three staff members. You will be working in a dynamic team with scientific and educational staff, another postdoc and a PhD candidate for this project, supported by the TU Delft Teaching Academy. The Teaching Academy is the network for and by lecturers of TU Delft with the mission to collaboratively enhance engineering education and drive education innovations across faculty boundaries.

While the chosen candidate will work in the IDEE team on transition, they will be appointed to the section Science and Engineering Education (SEEd), which is part of the department Imaging Physics at the Faculty of Applied Sciences, in the same section as one of the supervisors Dr. Anna Hotze. This will create the opportunity to discuss your research with SEEd colleagues and exchange ideas on science and engineering education. The Science & Engineering Education (SEEd) section is an academic group that conducts education, research and outreach in the field of STEM education. The section SEEd investigates science and engineering education across primary, secondary and tertiary levels with a focus on pedagogical approaches of monodisciplinary science subjects and more interdisciplinary forms of teaching and learning.

Job requirements
We are looking for an organized and motivated candidate with:

• A PhD degree, in one of the social sciences such as Educational Studies or Cognitive Psychology, with a strong interest in engineering and engineering education.
• Experience with educational design based research is a plus.
• Skills to organize the research work in consultation with a multidisciplinary team; ability to work through ambiguities, inconsistencies, and uncertainties that come when interacting with multiple stakeholders with different interests and values.
• Acquaintance with the secondary and higher educational system, with interest in the Dutch system, is a plus.

Contractadministrateur

Functieomschrijving

Bij TU Delft werk je aan de uitdagingen van morgen: van quantumtechnologie tot duurzame luchtvaart en van slimme gebouwen tot de energietransitie. In deze rol ondersteun je dat werk achter de schermen door contracten en inkoop- en inhuurprocessen administratief stevig te organiseren.

Je werkt voor alle acht faculteiten en tien universiteitsdiensten en maakt deel uit van een team van acht contractmanagers en twee contractadministrateurs. Jij werkt binnen het accountteam faculteiten en inhuur. Vanaf je start word je goed ingewerkt in de organisatie, onze werkwijze en de CATS-CM-methodiek. Daarna ga je zelfstandig aan de slag met inhuur- en contractbeheer en werk je nauw samen met de inhuur- en (inkoop)contractmanagers Procurement. Ook heb je regelmatig contact met contracteigenaren en realisatie- en verificatiemanagers binnen de faculteiten.

Je bent verantwoordelijk voor het administratief inhuur- en contractmanagementbeheer en ondersteunt het inkoopproces binnen Procurement. Je zorgt dat het contractmanagementsysteem juist, volledig en actueel is ingericht op basis van aangeleverde informatie. Je controleert invoer op eenduidigheid en volledigheid, voert contracten en projecten in en ondersteunt collega’s bij het correct vastleggen van gegevens.

Daarnaast verzorg je maandelijkse rapportages over de status van projecten en contracten en stel je rapportages op over uitgaven en spend in relatie tot contracten, onder andere met Power BI en het ERP-systeem. Je bent het eerste aanspreekpunt voor het contractmanagementsysteem en werkt samen met DAFS aan het operationeel verbeteren en actueel houden ervan.

Ook ondersteun je het inhuur-, inkoop- en contractmanagementproces administratief, bijvoorbeeld door het beheren van de centrale mailboxen van Procurement, het signaleren van knelpunten richting de afdelingshoofden en het beheren en actualiseren van standaardformulieren. Vanuit rapportages signaleer je waar het proces (niet) gevolgd wordt en werk je samen met de inhuur- of contractmanagers aan het beter naleven van de processen. Je levert een actieve bijdrage aan afdelingsbrede werkzaamheden en neemt deel aan overleg binnen Procurement en contractmanagement.

TU Delft vindt een gezonde werk-privébalans belangrijk. Daarom bieden we flexibele werktijden en, bij een fulltime dienstverband en als het werk het toelaat, de mogelijkheid om 40% per week vanuit huis te werken.

Functie-eisen

• Je hebt minimaal mbo werk- en denkniveau.
• Je hebt minimaal twee jaar relevante werkervaring in een administratieve functie, bij voorkeur met contractadministratie binnen een complexe organisatie.
• Je werkt gestructureerd en resultaatgericht, met oog voor naleving én optimalisatie van afspraken.
• Je communiceert helder met diverse stakeholders in het Nederlands en Engels.
• Je bent digitaal vaardig en werkt makkelijk met systemen en rapportagetools.
• Je bent leergierig en bereid je verder te ontwikkelen binnen het vakgebied inhuur- en contractmanagement.
