Position Description:    

Computational Postdoctoral Fellow - 100105
Division: MB-Molecular Biophysics & Integrated Bioimaging

Berkeley Lab’s (LBNL) Molecular Biophysics and Integrated Bioimaging Division (MBIB) has an opening for a Postdoctoral Fellow to join the team.

In this role, as part of MBIB and the Center for Advanced Mathematics for Energy Research Applications (CAMERA), you will develop advanced computational algorithms for multi-conformational reconstruction from cellular X-ray and electron tomography. This work involves research and development in new hybrid methods that couple model-based methods, optimization, and deep-learning to solve inverse problems from noisy, incomplete, and heterogeneous data to obtain state-of-the-art reconstructions. You will work in a multi-disciplinary team including biophysicists, computational biologists, and mathematicians to implement and test these tools on simulated and experimental data.

This position has an anticipated start date of December 1, 2023.

What You Will Do:
  • Develop algorithms for automated marker-less alignment of X-ray and electron tomography data.
  • Develop theory and optimization techniques for tackling noise and missing data for improved subtomogram resolution.
  • Develop data-driven methods for non-rigid deformations and generative modeling of conformational heterogeneity in electron tomography.
  • Apply these new algorithms to enable high-resolution 3D reconstructions of biomolecules from cellular tomographic data.
  • Publish scientific papers in high-impact journals and present findings at seminars and conferences.
  • Maintain documentation of theory, derivations, and results.

What is Required:
  • A recent Ph.D. (within the last 1-2 years) in Biophysics/Physics, Applied Mathematics, Computational Biology, Computer Science, or a related discipline.
  • Experience developing algorithms for reconstruction and physics informed machine learning.
  • Strong background in scientific computing including coding experience in C++, Fortran, and Python.
  • Knowledge of physics and mathematics of X-ray and electron microscopy.
  • Knowledge of numerical linear algebra, optimization techniques, and Fourier analysis.
  • Strong oral and written communication skills including the ability to efficiently organize technical information for publication and presentation.
  • Demonstrated interpersonal skills including experience collaborating with a diverse interdisciplinary research team.

Desired Qualifications:
  • Experience with PyTorch or TensorFlow.
  • Experience with software development for high-performance computing (i.e., openMPI, openMP, and GPU).
  • Experience with version control tools.
  • Interest in extending scientific computing to new imaging problems.

  • For first consideration, please apply with a curriculum vitae (CV) or resume by October 31, 2023.
  • This is a full time, exempt from overtime pay (monthly paid), 2 year (benefits eligible), Postdoctoral Fellow appointment with the possibility of renewal based upon satisfactory job performance, continuing availability of funds, and ongoing operational needs. You must have less than 3 years of paid postdoctoral experience.
  • The monthly salary range for this position is $7,828-$8,742 and is expected to start at $7,828 or above. Postdoctoral positions are paid on a step schedule per union contract and salaries are predetermined based on postdoctoral step rates. Each step represents one full year of completed post-Ph.D. postdoctoral and/or related research experience.
  • This position is represented by a union for collective bargaining purposes.
  • This position may be subject to a background check. Any convictions will be evaluated to determine if they directly relate to the responsibilities and requirements of the position. Having a conviction history will not automatically disqualify an applicant from being considered for employment.
  • This position will be performed onsite at Lawrence Berkeley National Lab, 1 Cyclotron Road, Berkeley, CA 94720.
