LAMMPS Authors

The core group of LAMMPS developers is at Sandia National Labs and Temple University:

If you have a question about or suggestion for LAMMPS, the best place to start is by posting it to the LAMMPS mail list, so anyone can respond and the answer is archived. You may be referred to one of the individuals listed on this page if they are the best person to answer your question.


The following folks are responsible for significant contributions to the code, or other aspects of the LAMMPS development effort. Many of the packages they have written are somewhat unique to LAMMPS and the code would not be as general-purpose as it is without their expertise and efforts.


As discussed on the history page, LAMMPS originated as a cooperative project between DOE labs and industrial partners. Folks involved in the design and testing of the original version of LAMMPS were the following:
