Service  I'm a regular reviewer for conferences NeurIPS, ICML, ICLR, MICCAI, ICASSP and journals TNNLS.


Fun fact 1  I am the father of two cats.

Fun fact 2  My spirit animal is a fox.

Joker 🤡 story 1  I still haven't published at NeurIPS, ICML or ICLR despite having served as a reviewer for 3 years and having won an outstanding reviewer award.

Joker 🤡 story 2  I have applied for Ph.D. positions three times. I got rejected from all applications in the first two attempts, and only received 1 offer out of 16 applications in the third attempt.
