Post Doctoral Research Scientist - Low Voltage Ptychography

View Full Job Details

The Rosalind Franklin Institute (the Franklin) is a new national Research Centre, funded by the UK government through UK Research and Innovation, dedicated to bringing about transformative changes in life science through interdisciplinary research and technology.

As a postdoctoral scientist within the correlated imaging theme of the Franklin, you will develop electron Ptychography for imaging of biological samples. It has been shown by Henderson and Rousseau that for conventional phase contrast TEM imaging lower voltages have advantages in many instances. You will explore the merits of Ptychography at different voltages for both small molecules and also for large scale cellular structures. State of the art ptychographic reconstruction algorithms will be employed and extended to optimise the reconstruction process to minimise radiation damage. You may also explore the use of non-standard (sparse) acquisition modes working with other staff at the Rosalind Franklin Institute. A key part of the role will be to collaborate with staff at the electron Physical Sciences Imaging Centre (ePSIC) who are also developing optimised Ptychographic methods applied to materials science.

The post holder will report to Dr E Liberti, Staff Scientist at the Franklin, and ultimately to Dr Judy Kim Deputy Science Director at the Franklin and Professor Angus Kirkland, Science Director at the Franklin. Work at ePSIC will be in collaboration with Dr Chris Allen, Principal Staff Scientist.

Responsibilities

You will:

• Participate in all aspects of the methodology development and its application.

• Develop the scientific scope of individual projects, formulate relevant research questions, conduct individual independent research, analysing detailed and quantitative data, and generate original ideas by building on existing concepts.

• Design and perform experiments on microscopes at the Franklin and at ePSIC.

• Develop a workflow for Ptychographic reconstruction of biological systems.

• Present findings at national and international meetings/conferences and keep up to date with developments in the field.

• Publish research articles in leading academic journals.

• Participate in and support the public engagement and widening access activities of the Franklin.

• Foster collaborations with staff at ePSIC

• Work with others in a safe and timely manner considering all those who will be affected by your work.

• Any other duties that arise in the normal running of the Franklin and that can be reasonably requested of the post holder.

The above job description reflects the present requirements of the post, and as duties and responsibilities change/develop, the job description will be reviewed and be subject to amendment in consultation with the post-holder.
