In 2017, together with Sanjay Jain, Bakhadyr Khoussainov, Wei Li, and Frank Stephan, he announced an algorithm for deciding parity games in quasipolynomial time.[8] Their result was presented at the Symposium on Theory of Computing 2017[9] and won a Best Paper Award.[10]

He was awarded the National Order of Faithful Service in the degree of Knight[11] by the President of Romania, Mr. Klaus Iohannis, in June 2019.

gollark: You're wrong and you still don't understand what lossy compression means.
gollark: This seems unlikely also, since rerecording it discards information.
gollark: If your WAV file is the original one from whoever made the song, it might sound better. If your WAV file is just generated from the MP3, it will be identical to playing back the MP3 normally.
gollark: Converting to JPEG has dropped information, information which the design of JPEG treats as relatively unimportant to human perception, and if you convert back to lossless you'll just store the same information as the JPEG retains less efficiently.
gollark: JPEGs are lossy too. What happens if you take a poor-quality JPEG of a meme and convert it back to PNG (which is lossless)? Does it look better? No.
