Sandra Guasch Castelló


Dr. Sandra Guasch joined Scytl in 2009 as a key contributor to the Research Team. As a researcher specialized in cryptography, she has participated actively in electronic voting projects in Europe, United States and Asia Pacific. Her main focus areas include analysis at a mathematical and implementation level of public key cryptography algorithms, design and evaluation of security protocols for electronic voting projects and participation in risk analysis of electronic voting solutions. She also participates in the collaboration between Scytl and several Spanish universities in research projects and in the diffusion of electronic voting and security knowledge among the student community.
Before joining Scytl, Sandra worked in the Universitat Politècnica de Catalunya performing research support tasks, some of them for the public administration (Generalitat de Catalunya).
Sandra has a Bachelor Degree in Telecommunication specialized in Audiovisuals and a Master Degree in Telecommunication from the Universitat Politècnica de Catalunya. She recently obtained her PhD degree on voter verifiability in electronic voting in the same university, with a thesis called “Individual Verifiability in Electronic Voting”. She is co-author of 4 patents and 12 publications on electronic voting and security-related topics.
