About me

Hi, my name is The-Anh Ta (Tạ Thế Anh in Vietnamese). Since 2023, I have been working as a Research Scientist at Data61, The Commonwealth Scientific and Industrial Research Organisation (CSIRO), Marsfield, NSW, Australia. I do research in Applied Cryptography (Digital Signature, Zero-Knowledge Proof) and Machine Learning (Neural Network Pruning, Robustness). Here is the link to my GoogleScholar page. Before moving to Australia, I was at KDDI Research, Japan; and AI Center, FPT Software, Vietnam. I obtained my PhD in Mathematics from the Paris-Saclay University, Orsay, France (Link to my thesis). Before that, I did my undergraduate studies (BSc and MSc) in Mathematics at the Eotvos Lorand University in Budapest, Hungary. I grew up in Vinh Phuc (renamed to Phu Tho since 2025), Viet Nam.
