Before that, I was a postdoc at the <a href="https://www.iis.sinica.edu.tw/">Institute of Information Science</a> of <a href="https://www.sinica.edu.tw/">Academia Sinica</a>, Taipei, Taiwan. Before that, I was at the <a href="https://www.mpi-sp.org/">Max Planck Institute for Security and Privacy</a>, Bochum, Germany. Before that, I was at the <a href="http://www.ru.nl/dis/" >Digital Security group</a> at <a href="http://www.ru.nl">Radboud University</a>, Nijmegen, The Netherlands. Before that, I was at the <a href="https://surrey.ac.uk">University of Surrey</a>, Guildford, United Kingdom. In 2022, I obtained my PhD from <a href="http://www.ru.nl">Radboud University</a>, Nijmegen, The Netherlands under the supervision of <a href="https://cryptojedi.org">Peter Schwabe</a> and <a href="https://www.iis.sinica.edu.tw/pages/byyang/">Bo-Yin Yang</a>. My dissertation on Polynomial Multiplication for Post-Quantum Cryptography is available <a href="thesis/">here</a>.
