Research Groups “physics of Low Dimensional

The research groups “Physics of low dimensional materials” (Dr. Laura Vittadello) and “Ultrafast Physics” (Prof. Mirco Imlau) are seeking to appoint for

**1 Research Assistant (PHD) in Low Dimensional Physics (M/F/d)**
**(Salary Level** **E 13 TV-L, 65%)**:
**1 Research Assistant (PhD) in Ultrafast Physics (M/F/d)**
**(Salary Level E 13 TV-L, 65%)**:
**The research assistant working with Dr. Laura Vittadello** will focus on laser-induced energy transfer from nanoparticles to chemical compounds and/or cells with the goal to manipulate the plasma membrane functions.

**Via this topic you will**:

- Learn how to tailor colour and intensity of pulsed lasers in a microscope to interact in a non destructive way with nanoparticles, cells and chemical compounds.
- Transfer the knowledge of surface functionalization to polar surfaces and study its impact on the laser-induced energy transfer.
- Explore optical approaches to the photo-release of chemical compounds attached to nanoparticles in function of dimension, shape & defects, but also synthesis methods.
- Implement an optical tweezer to control the movement of the developed nanoparticles using femtosecond laser pulses.

**The research assistant working with Prof. Mirco Imlau** will focus on the tailoring of femtosecond pulse trains and signal detection techniques to enhance energy transfer of upconversion nanoparticles for interrogation and photomanipulation at single molecular level.

**Via this topic you will**:

- Learn about the interplay between femtosecond pulse exposure, optical features of microscopic systems and samples, and digital signal detection in imaging systems.
- Reveal insight to the relation between pulse-induced energy flow and defect architecture (size, shape, doping concentration, core/shell-ratio, host material, etc.) of core-shell nanoparticles.
- Study the enhancement of nanoparticle emission by combining tailored fs-pulse trains with coincidence and correlation detection techniques.

**Your Duties**:

- Participate in the DFG-funded research project “Energy transfer from nanoparticle architectures for sub-diffraction photo-manipulation“ (Vittadello) or “Enhancement of the ucLRET: parametric tuning of femtosecond pulse trains, image coincidence detection and digital image correlation” (Imlau) of the RTG 2900 “Rationally designed surface architectures for nanoscale interrogation and manipulation of biomolecules at membranes”.
- Supervise bachelor and master students (in your 2nd or 3rd year).
- Work & communicate in an interdisciplinary team, write research articles and present your results at national and international conferences.
- Participate in the development of hybrid thinking and related workshops of the research training group.

**Requirements**:

- Completed master’s degree (M.Sc.) in physics or physics/chemistry, or related fields of study
- Interest in interdisciplinary research
- Ability to work in a team and willingness to engage in multilateral research cooperation
- Written and spoken English skills
- Goal oriented and structured way of working

**We offer**:

- Laser class 4 laboratories equipped with chemical wet benches and S2 biological certification
- Cross disciplinary competences from scientific (physical-chemistry, bio-chemistry and bio-physics) and technical view point (lasers, electron and light microscopy, time-resolved spectroscopy, handling of biological samples, nanomaterial synthesis and characterization)
- Research and communication oriented seminars and workshops to foster scientific reputation and independency in interdisciplinary research fields.
- Technique based seminars and workshops at industrial level.
- Tandem supervision in an interdisciplinary team along the European Charter for Researcher
- Inclusion in a scientifc and industrial international network.
- Research stays at European collaboration partners and participation to (inter)national conferences.
- 30 days of holiday per full calendar year
