Cryptography
I mainly work on code-based cryptosystems that are designed to provide security against attacks from both classical and quantum computers.
I have been involved in several cryptosystems submitted to the NIST's Post-Quantum Cryptography Standardization Project.

Automated Planning and Multi-Criteria Decision Analysis
I studied preference-based planning in the case where preferences are represented using the Multi-Attribute Utility Theory along with a Choquet integral.
This led to the creation of ChoPlan, a planner that was deployed in an information system for planning in crisis management context.
