Elisabeth Oswald

Elisabeth was born in Wolfsberg, a small town in Carinthia, Austria.  After finishing school (BORG Wolfsberg) in 1993, she studied Technical Mathematics with an emphasis on information processing at Graz University of Technology. She finished her studies 1999 with a master thesis on cryptanalysis of DES. During her master thesis she started working for the Institute for Applied Information Processing and Communications (short but not easier to pronounce: IAIK). She continued working at IAIK and enganged in teaching and research. As a PhD student, she spent several months with the COSIC research group in Leuven where she "re-established" their DPA setup and DPA research.

She finished her doctoral studies in 2003 with Reinhard Posch and Bart Preneel as her assessors. Since then, you may officially address her as "Frau Diplom-Ingenieur Doktor Oswald". She decided to stay with Graz University of Technology and became employed as assistant professor. Hence, since that time you may even address her as "Frau Universitätsassistentin Diplom-Ingenieur Doktor Oswald". Before things got too worse (in Austria you can only accumulate titles), she decided to take a leave of absence from Graz and she joined the cryptography group at University of Bristol as a lecturer. Since then, you may simply call her "Elisabeth". Note that Elisabeth is actually not her first name.

Elisabeth's main scientific interest is side-channel cryptanalysis, but she is also likes all other kinds of cryptanalysis and she has a preference for elliptic curve cryptography. If you want to make her happy then bring her chocolate or Belgian beer (preferably Hoegaarden). Elisabeth is also interested in all kinds of stories, no matter whether they are real (ancient history, preferably Egyptian) or fiction (the universerse is full of stars), and she tries to understand human behaviour (psychology and social history).

Elisabeth was and is involved in the organization of different major events. This year, she is the general chair of CHES.
