Postdoc Position in Development of Multiplexed Bioimaging Method

Department of Chemistry
Faculty of Science
University of Copenhagen

To understand the functions and correlations between biomolecules in complex (cellular) systems, we need to simultaneously visualize the distributions of multiple populations at the subcellular level. Take part in the exciting development of multiplexed bioimaging method for visualizing and understanding different biomolecules’ location, function, and correlation.

The Department of Chemistry, Faculty of Science at University of Copenhagen invites applicants for a Postdoc position in development of multiplexed bioimaging method.

Start date of the position is 1 April 2023 or as soon as possible thereafter. The position is initially offered for 2 years with an option of extension.

Background:

The research group of Assistant Professor Junsheng Chen at Nano-Science center and Department of Chemistry invites applicants for a Postdoc position in the development of multiplexed bioimaging method. The project is part of the research project “Subcellular multiplex imaging with ultrabright fluorescent nanoparticles”, start in January 2023, led by Assistant Professor Junsheng Chen, financed by Novo Nordisk Foundation.

The project

The project aims at developing imaging method to achieve multichannel super-resolution imaging with conventional fluorescence microscopy. Recently, we have achieved a breakthrough by developing the brightest full-organic fluorescent nanoparticles based on a molecular self-assembly approach, called: Small‐Molecule Ionic Isolation Lattices (SMILES)*. Besides their unsurpassed brightness, we also have the full control of the fluorescence emission color (from blue to near infrared) and fluorescence lifetime (from nanosecond to microsecond). In this project, we will extend the number of simultaneous detection channels and develop multiplex microscopy by combining the “normal” color channels with fluorescence lifetime channels imaging. We will use the developed multiplexed imaging method to tackle the key question about protein translation at the subcellular level.

Our research project is highly interdisciplinary including collaborations with physicists, chemists, medical researchers, and biologists in the industry and at universities. Throughout the project, the candidate will be trained to be truly an interdisciplinary researcher in a creative and cross-disciplinary environment.

Duties and responsibilities

This project seeks to develop new multiplexed bioimaging method for deepening molecular-level understanding of protein translation at the subcellular level.

As a postdoc your work responsibilities will include but not be limited to:

  • You will need to perform optical setup development, data collection, analysis and communicate research work.
  • You will also need to participate in regular laboratory tasks within the research group as part of the normal daily activities in a team-driven laboratory environment.
  • Supervising master students and PhD students.
  • Teaching activities
  • It may also require participation in national and international conferences as agreed.

Qualification

We are looking for a talented, highly motivated, and creative scientist who is interested in working with fluorescent bioimaging and optical spectroscopies. The ideal candidate will have a strong optics, microscopy background, in particular fluorescent microscopy and bioimaging.

  • The candidates are required to have a PhD degree or equivalent in chemistry, physics, optics, biological sciences or other relevant fields of science.
  • Documented hands-on experience in optical microscopy/spectroscopy.
  • Excellent scientific track-record, including at least one publication as first author in a high-quality, peer reviewed international journal.
  • The candidate must be fluent in English and have good communication skills, both oral and written. Demonstrate enthusiasm, motivation, and confidence.
  • the ideal candidate has several of the following qualifications:
  • Experience with optical setup alignment.
  • Basic knowledge of optical spectroscopy.
  • Experience with fluorescent bioimaging.
  • Hands-on experience with performing basic programming tasks (Labview, Python, Matlab, or C++) for instrumentation, data acquisition and data analysis.
  • Experience with supervision of students
  • Experience with fluorescence lifetime imaging (FLIM) is an advantage

As part of the University, we wish our staff to reflect the diversity of society and thus welcomes applications from all qualified candidates regardless of personal background.

Our group and research- and what do we offer?

Light induced processes make the world bright and colorful. Furthermore, innovative ways of utilizing such processes have broad application possibilities in modern technology such as: bioimaging, solar cells, communication and photocatalysis.

Our group studies both the fundamental and applied aspects of the interactions between light and materials. In particular, we explore functions, underlying photophysics and photochemistry of fluorescent molecular materials and semiconductor nanomaterials.

We develop fluorescent materials and methods for bioimaging applications. We use femtosecond optical spectroscopy to reveal fundamental photophysical processes in these materials and provide a thorough understanding and guidance for developing new materials with improved performance. We carry our interdisciplinary research projects by collaborating with physicists, chemists, medical researchers, and biologists in the industry and at universities.

We offer a creative and exciting research atmosphere at the vibrant border between chemistry, physics and biomedicals.
