Elmer Gethin Rees

Welsh Mathematician (1941–2019)

Projective Spaces and Associated Maps served as the foundational PhD thesis for Elmer Gethin Rees, completed in 1967 at the University of Warwick under the supervision of David B. A. Epstein. This early academic milestone initiated a prolific career that saw him traverse various international institutions before establishing a long-term professional base within the Scottish capital.

Academic Trajectory and Research

Born in Llandybie in 1941, Rees pursued his undergraduate studies at St Catharine's College, Cambridge. His intellectual focus spanned a diverse spectrum of mathematical disciplines, specifically topology, differential geometry, algebraic geometry, linear algebra, and Morse theory. His expertise eventually extended into the practical applications of robotics. Throughout his tenure at the University of Oxford and the University of Edinburgh, he fostered the development of emerging scholars, supervising at least 15 doctoral candidates, including Anthony Bahri, John D. S. Jones, Gregory Lupton, Jacob Mostovoy, Simon Willerton, and Richard Hepworth.
