I started my professional career as a dilligent student of pure mathematics, doing
all kinds of horrible things (even differential equations - ugh!), but
progressively moved toward theoretical computer science resulting in my dissertation
Typed Lambda Calculi. Since I thought it was pretty good and definitely worth more
than one lousy degree, I submitted it twice
and consequently got two (M.Sc. from
University of Leeds and Mgr. from
Masaryk
University in Brno).
