Emma Schymanski (née Craven) is an Australian chemist known for her work identifying unknown organic compounds, particularly pollutants, and is an advocate for open science.

[12] Identifying and tracking unknown organic compounds continues to be an avenue of research pursued by Schymanski[13] and she is a co-author on a 2014 textbook describing these methods.

[21] Within this field, Schymanski is working to automate the identification of a group of fluorinated compounds called ‘per- and poly-fluoroalkyl substances’ (PFASs) in order to increase the ability of researchers to find unknown PFAS in the environment.

[27] Schymanski's 2014 publication in Environmental Science & Technology[28] establishes a means to estimate confidence in the quality of unknown organic compound identifications and, as of 2021, has over 1000 citations.

In 2018, Schymanski considered this paper her greatest achievement because it established the standard for compound identification in metabolomics and encouraged community conversation about future of these tools.
