Applications are invited for a postdoctoral position at Johns Hopkins University, with a designated visiting scholar position at Sandia National Laboratories (Albuquerque, NM). The position will focus on in-situ transmission electron microscopy (TEM) experiments and machine learning. Experiments will be performed under various combinations of extreme environments utilizing facilities at both the Johns Hopkins University Materials Characterization and Processing Center and the in-situ ion irradiation TEM (I3TEM) facility at Sandia National Laboratories (Albuquerque, NM). This work will involve in-situ ion irradiation coupled with other in-situ stimuli, such as mechanical strain, heating, and various environments and machine learning techniques.

The successful applicant will be part of a dynamic, multi-university team which includes both theoretical and experimental personnel. The focus of the applicant will be to investigate and characterize radiation damage processes in metallic materials, including pure metals and high entropy alloys.

Ideal candidates will have experience with in-situ and high resolution TEM, sample fabrication including focused-ion beam (FIB) lift-out methods, and defect and microstructural analysis of metallic systems

Basic Qualifications:

  • A Ph.D. in materials science, physics, mechanical engineering, or related disciplines is required.
  • Experience with in situ TEM imaging and diffraction of metallic materials.
  • Knowledge of crystalline defects and microstructure.
  • Experience image processing and image techniques.
  • Experience in scripting/programming (Python, Matlab, C++) for data processing.
  • Must be comfortable to travel to Sandia National Laboratories in Albuquerque, NM 87123


Preferred Qualifications:

  • Knowledge of aberration corrected high resolution TEM.
  • Experience with machine learning techniques.
  • Ability to disseminate research findings through peer-reviewed articles and presentations.
  • Knowledge of precession electron diffraction and/or electron backscattered diffraction.

During the Influenza ("the flu") season, as a condition of employment, The Johns Hopkins Institutions require all employees who provide ongoing services to patients or work in patient care or clinical care areas to have an annual influenza vaccination or possess an approved medical or religious exception. Failure to meet this requirement may result in termination of employment.

The pre-employment physical for positions in clinical areas, laboratories, working with research subjects, or involving community contact requires documentation of immune status against Rubella (German measles), Rubeola (Measles), Mumps, Varicella (chickenpox), Hepatitis B and documentation of having received the Tdap (Tetanus, diphtheria, pertussis) vaccination. This may include documentation of having two (2) MMR vaccines; two (2) Varicella vaccines; or antibody status to these diseases from laboratory testing. Blood tests for immunities to these diseases are ordinarily included in the pre-employment physical exam except for those employees who provide results of blood tests or immunization documentation from their own health care providers. Any vaccinations required for these diseases will be given at no cost in our Occupational Health office.
