"Academic Careers in Statistics" vs "Statistics Careers in Academia"
Academic Careers in Statistics points to academic careers within (in the sense of restricted to) the study of statistics, statistical careers of an academic nature, a description that ignores the possibility of a non-statistical part to the career - such as statistician's rising to the position of university principal, where their statistical skills are no longer explicitly required.
Statistics Careers in Academia points to statistical careers within (in the sense of as part of) academia, the careers being placed within a wider academic context. As above, wider academic roles are ignored.
Academic Careers for Statisticians points to an academic career suitable for statisticians. It leaves open all possibilities: that the academic career will involve the study of statistics; and that academia also offers other opportunities for statisticians.
From this analysis I prefer the last as the most flexible title.
