Bereich

Bremen University of Applied Sciences is cosmopolitan and promotes applied research. With approximately 70 degree programs—most of which are international—and innovative, lifelong learning formats, Bremen University of Applied Sciences offers nearly 9,000 students opportunities for personal development and a successful start to their careers. Thanks to our international profile, we have held a leading position among universities of applied sciences for decades. Improving study conditions and creating attractive workplaces are priorities for us, and these are reflected in the university’s development planning.

This PhD position is embedded in a DFG-funded research programme investigating how light and the circadian clock control the daily deposition of chitin in the insect cuticle. Insects form their exoskeleton in daily growth layers — alternating bands of differently oriented chitin fibres — a process that in some species is directly regulated by a peripheral epidermal light sensor. This phenomenon has profound implications for understanding how environmental cues shape biomaterial architecture and mechanical performance at the nanoscale. The project will, for the first time, systematically investigate this phenomenon across a broad range of insect groups using a combination of comparative microscopy, controlled illumination experiments, and molecular clock-gene analysis.

Aufgabengebiet

• Comparative morphological and physiological analysis of rhythmic cuticle deposition across selected insect taxa, using polarised-light microscopy and scanning electron microscopy (SEM)
• Design and execution of controlled illumination experiments to characterise the spectral and intensity-dependent response of the epidermal light sensor in locusts and other insect species
• Molecular analysis of circadian and light-sensitive gene expression in locust epidermal tissue using molecular methods
• Insect colony maintenance, sample preparation, data management, scientific writing, and dissemination of results at international conferences

Voraussetzungen

• Completed University Degree (Master‘s/Uni-Diploma or equivalent) in zoology, biology, entomology, organismal biology, molecular biology, or a closely related field
• Sound knowledge of animal biology and/or experimental molecular biology
• Practical experience in histological sample preparation, light microscopy or SEM
• Good command of English (scientific reading and writing, level B2 or above)
• Ability to work independently and to take responsibility for experimental work
• Willingness to work with live insects and perform hands-on laboratory work, including occasional weekend duties during animal care periods
• Team-oriented approach and openness to interdisciplinary collaboration

The following are desirable:

• Prior exposure to molecular biology techniques such as RT-qPCR
• Experience with insect handling or laboratory colony maintenance
• Interest in biomaterials, chronobiology, or comparative physiology
• Basic knowledge of German (advantageous for administrative communication)
