Lund University welcomes applicants with diverse backgrounds and experiences. Gender equality, equal opportunities, and diversity are fundamental principles for all parts of our operations.

Description of the Department

Our department at the Enoch Thulin Laboratory develops laser spectroscopic measurement techniques for applications in industry and the environment.

Within the group for biophotonic remote sensing, we are experts in the interaction of light with biological tissue and living organisms. We also have a long tradition of taking realistic photonic instrumentation from the laboratory into natural environments. Specifically, we have developed Scheimpflug lidar for environmental analysis. For over a decade, we have been leaders in laser-based remote sensing of insects, both in the aspect of creating field sensors and in the fundamental understanding of light's interaction with freely flying insects. We are now trying to push the boundaries of ultraviolet remote sensing and develop applications for classifying pollen on insects, lichens in tree canopies, and marine applications such as zooplankton movement and profiling of sea lice.

Being a PhD Student

As a PhD student, you are both admitted as a student and employed at Lund University.

As a research student, you are trained in a scientific approach. This can be briefly described as gaining practice in critical and analytical thinking, solving problems independently with the right method choices, and developing research ethics awareness. Additionally, you will have the opportunity to work on projects, develop your leadership skills, and enhance your pedagogical abilities. Throughout your studies, you will be guided by supervisors. Research studies conclude with a dissertation and a doctoral degree.

Subject and Project Description

The project aims to develop and explore ultraviolet hyperspectral lidar technology and test several applications. Within the project, we will design a hyperspectral lidar in the deep ultraviolet and a spectral marine lidar. The development is done using ray tracing, Computer Aided Design, and 3D printing. After calibration, the instruments will be tested in the field for applications in pollination, lichens in tree canopy analysis, zooplankton's daily movement, and profiling of pests in aquaculture. Fieldwork is interdisciplinary in collaboration with ecologists in the field. Validation of the method will require complementary laboratory reference measurements.

Job Responsibilities

You will primarily focus on your doctoral education, which includes participation in research projects as well as doctoral courses, seminars, and conferences.

The job responsibilities include:

• Designing a deep ultraviolet hyperspectral lidar (200-400 nm) using a laser-driven plasma light source for classifying pollen and lichens.
• Designing a spectral marine lidar (400-800 nm), spectral lidar for profiling zooplankton and sea lice.
• Working with ray tracing, Computer Aided Design, and 3D printing of optomechanical layout.
• Calibrating instruments for distance, scattering cross-section, wavelengths.
• Conducting field and laboratory measurements of pollen on insects and lichens in tree tops.
• Conducting field trials regarding diurnal variation in zooplankton movements in the Faroe Islands.
• Conducting field trials regarding sea lice in Norwegian fish farms.
• Participating in the group's field and measurement campaigns and collaborating with others in the group as well as interdisciplinary collaboration with partners from biology and ecology.
• Contributing to popular science communication.
• The job responsibilities may also include participation in teaching and other departmental work (max 20% of working time).

Qualifications

To be accepted and employed as a PhD student, you need to meet the requirements below.

Eligibility Requirements

You meet the basic eligibility for doctoral education if you have:

• completed a degree at the advanced level, or
• completed course requirements of at least 240 higher education credits, of which at least 60 higher education credits at the advanced level, or
• acquired equivalent knowledge in some other way.

The requirements for special eligibility for the doctoral education subject physics are met by those who have:

• at least 30 higher education credits at the advanced level relevant to the subject area, of which a thesis of at least 15 higher education credits at the advanced level, or
• a master's degree in engineering physics or a related field, or a master's degree in physics or a related field.

The special eligibility may also have been obtained through other equivalent education, which is assessed in each individual case. To enable interdisciplinary initiatives and significant deepening in certain areas, other qualifications than the applicant's subject-specific competence in physics may be considered.

Finally, it is required that the student is assessed to have the ability needed to benefit from the education.
