About The Position

Lawrence Berkeley National Laboratory is hiring a Theoretical Atomic, Molecular and Optical Sciences (AMOS) Postdoctoral Fellow within the Chemical Sciences division. This position will develop theoretical and computational methods for the sophisticated treatment of the interaction of femtosecond and attosecond pulses of UV and X-ray radiation with atoms and molecules. A principal focus of this research is the application and development of ab initio methods for treating the molecular electronic ionization continuum. The holder of this position will apply theoretical methods already developed by the Atomic, Molecular and Optical Sciences (AMOS) theory group to such problems and extend those methods to treat new problems in ultrafast AMO physics. An essential goal of this position is to develop theoretical models and interpretations of attosecond time delays, transient absorption, time-resolved molecular photoionization and other multipulse ultrafast experiments. We’re here for the same mission, to bring science solutions to the world. Join our team and YOU will play a supporting role in our goal to address global challenges! Have a high level of impact and work for an organization associated with 17 Nobel Prizes!

Requirements

Ph.D. in Physics or Chemistry with a thesis in the area of the theory of the interaction of ultrashort radiation pulses with atoms and molecules including molecular photoionization -- or in a closely related area of theoretical chemistry, theoretical chemical physics, or physics.
Strong background in collision theory relevant to molecular photoionization and electron-molecule interactions.
Ability to program in modern Fortran and Python (and occasionally in C++) and use AI tools to create and modify code in those languages.
Mastery of modern numerical methods used in chemical physics and atomic and molecular physics.
Ability to communicate effectively in English with colleagues and coworkers.
Good scientific writing skills.

Nice To Haves

Preparation of presentations, both oral and written, on the research.
Communicate results in group meetings and participate in professional activities, as appropriate.
Ability to program modern massively parallel computers using Message Passing Interface (MPI) and OpenMP, or sufficient computational background to acquire parallel computing skills quickly.
Experience in large-scale computer code development.
Experience with computational electronic structure methods in Chemistry.

Responsibilities

Conduct research in the area of the interaction of femtosecond and attosecond light pulses with molecules.
Develop new theoretical approaches to these problems, including the ab initio description of the molecular ionization continuum.
Write programs implementing new theoretical methods on massively parallel supercomputers.
Collaborate actively with members of the AMOS theory and experimental groups.
Prepare manuscripts describing scientific results for publication in scientific journals.
