Post-doc position with scholarships in OPUS-22 National Science Centre

A group search to appoint two post-doctoral fellow for research in the OPUS-22 project entitled „Development of three-photon emitting radiotracers for positronium imaging". The project is funded by the National Science Centre. The short description of the research can be found here.

The research group of Prof. Paweł Moskal invites applications for a postdoctoral position in the OPUS-22 project entitled „Development of three-photon emitting radiotracers for positronium imaging”.

The minimum requirements for candidates are:

  • PhD diploma in Natural Sciences, Engineering, Computer Science, Mathematics, or related field of science;
  • experience in building and calibration of radiation detectors, advanced multi-level data analysis, Monte-Carlo simulations, advanced level statistical inference, and computer programming;
  • good knowledge of English (spoken and written).

The successful applicant is expected to take part in the following research tasks:

  • experiments:
    • commissioning of the modular J-PET scanner in view of three-gamma detection,
    • data taking with modular J-PET using point-like 22Na, 18F, 44Sc, 44mSc, 72As isotopes arranged at various configurations and with various relative activities for validation of elaborated software procedures including 2γ MLEM and Time-of-Flight Filtered Back Projection, 3γ image reconstruction, and positronium imaging. Experimental tests for the evaluation of NEMA characteristics of the modular J-PET detector for the case of the separate and simultaneous 2γ and 3γ imaging,
    • data taking with linear, and NEMA phantoms filled with radiopharmaceuticals labeled with 22Na, 18F, 44Sc, 44mSc and 72As for testing of multi-photon and positronium imaging reconstruction procedures;
  • data selection, analysis and simulations:
    • tuning of analysis procedures for events identification and selection,
    • detailed calibration of the modular J-PET tomograph,
    • development of methods for identification of de-excitation gamma quanta (prompt photon) as well as annihilation gamma quanta from 2γ and 3γ decays for the modular J-PET. Optimization of the selection criteria for each isotope separately. Simulation of physical and instrumental background. Elaboration of background suppression method;
  • image reconstruction:
    • computer implementation of methods for the reconstruction of time and position of annihilation into 2γ and 3γ. Preparation and computer implementation of procedures for fitting of life-time spectra and extraction of contributions from para-positronium, direct annihilation and ortho-positronium. Conceptual elaboration and computer implementation for prompt+2γ, and prompt+3γ positronium imaging,
    • elaboration of the method for simultaneous imaging with beta+gamma isotopes (22Na, 44/44mSc, or 72As ) and 18F. Reconstruction of positronium and 2gamma images taken simultaneously for various configurations of simple phantoms. Tuning of the multi-isotop image reconstruction method. Optimization of the relative concentration of (44/44mSc, 72As ) and 18F for the most efficient simultaneous multi isotope imaging.

The candidates should submit applications containing the following documents:

  1. Short application including motivation letter (maximum three pages).
  2. Scientific CV including list of publications.
  3. At least two letters of recommendation (preferentially send directly to P. Moskal via e-mail).

All documents should be submitted in the PDF format to the address:

The positions will start on the 1st of March 2023 and will be available maximally for 3 years.

We offer contract with the remuneration of 10000 PLN per month brutto-brutto equivalent to about 6000 PLN netto plus social and health insurance.

The deadline for submission of applications is 15th of December 2022.
The candidates will be informed (by email) of the result of the selection before 4th of January 2023.
