meriSTEM is an ANU initiative providing online learning resources and support to Australian senior secondary science teachers and students. We cater to senior physics, chemistry, biology, and Earth and environmental science.

The program is free and is made up of the video, worksheet, quiz and other contributions from many academics and students. We welcome everyone to be involved.

Undergrad research and internship projects offer students a chance to be a member of the meriSTEM team.

Some nuclei, like stable ^6,7Li and ⁹Be or radioactive ⁸Li and ⁶He, are weakly-bound, which gives them a cluster structure which can be broken apart with very little input of energy. These nuclei show a huge variety of behaviors which challenge our understanding of nuclear reactions, requiring experimental measurements. 

This project aims to use a machine learning algorithm to perform beam alignment in an optics experiment. It would involve mode-matching two optical beams using motorised mirror mounts. Additional degrees of freedom like lens positions and beam polarisation can be added later.
