The Microscopy group in X-ray Science Division of Advanced Photon Source at Argonne National Laboratory is seeking a postdoctoral researcher to work on cutting-edge ptychography technique development for dynamics imaging. The primary goal of this project is to develop single-frame ptychography methods that eliminate the need for scanning, enabling fast imaging and the visualization of dynamic processes in samples with significantly higher temporal resolution than traditional scanning methods. The selected candidate will simulate and design the experimental setup, and then perform single-frame ptychography experiments and corresponding data analysis. Following the successful demonstration of the technique, the candidate will collaborate with team members from material science to apply these methods to scientific samples and characterize dynamic behaviors. The candidate will be part of a highly collaborative team and actively interact with other groups, including optics, computation, and time-resolved research.

Position Requirements

• This level of knowledge is typically achieved through a formal education in Physics, or a related field at the PhD level with zero to five years of employment experience.

• Strong knowledge of coherent imaging, light modulation, Fourier-domain signal processing, X-ray physics, etc.

• Proficiency in Python or other scientific programming languages.

• Programming skills in numerical methods for image processing and AI/ML methods for quality improvement are advantageous.

• Experience with experimental physics and/or engineering is a plus.

• Presentation and documentation skills for describing research and clearly communicating results and data.

• Excellent collaboration skills and ability to work effectively in a team environment with people of diverse backgrounds.

• Ability to model Argonne’s core values of impact, safety, respect, integrity, and teamwork.
