This presentation will describe approaches to uncover correlations that are not<br />

easily discernable. We describe the application of Topological Data Analysis<br />

(TDA) to capture the “shape” of data in a multiscale manner to probe for hidden<br />

correlations. We demonstrate its application in both materials imaging and<br />

materials modeling. In the former case we show how such informatics methods<br />

can reveal nanoscale morphology atom probe tomography images. In the case<br />

of materials modeling it is shown that one can uncover nuances between<br />

crystallographic structure and electronic structure. Our work reveals new<br />

information on how chemical site occupancy within molecular nanocluster units<br />

defines new groupings of chemical homologues in complex structures.<br />
