Thesis Title: ‘A Study of Shell Stars’ with R.F. Garrison
The spectroscopic variations of 13 shell stars were examined throughout their known histories. With archival plates from other observatories and present epoch material, the histories of shell stars which had been forgotten in recent years were updated. Through extensive photographic spectrophotometry, a quantitative basis was provided for comparison with published models of shell stars. In particular, such data on a complete shell episode of the shell star, Pleione, were amassed for the first time and shown to be in good agreement with the predictions of the stellar wind model. Data collected for other shell stars, however, showed equally good agreement with the elliptical ring and binary models.

Thesis Title: ‘A Search for New Peculiar A Stars’ with D.A. MacRae
The plate file of the David Dunlap Observatory was searched for new Ap stars. A total of 19 previously unidentified Ap stars was found of which several have since proven to be especially interesting. A number of new metallic-line A stars were also discovered as part of this work.
