Dr Cătălina Cangea

Quantitative Researcher

Biography

I am a Quantitative Researcher at Qube Research & Technologies, previously co-lead of Generative Music at Google DeepMind. I have 9 years of ML experience and an extensive background in computer science and competitive programming.

I like to solve problems in the real world using my ML expertise and thrive in collaborative environments where everyone works towards a shared agenda. Music is my lifelong passion - I’ve brought essential contributions to AI tools that support the creative process of making music. I was part of the core Lyria and Music AI Sandbox teams and GDM tech lead for the YouTube Dream Track quality workstream.

My PhD at King’s College, University of Cambridge was awarded with no thesis corrections. I also earned a First Class BA and an MPhil with Distinction from Cambridge. During my studies, I interned at Big Tech and startup companies, top research labs in academia and industry. Since graduate years, I’ve mentored and taught for 100s of hours. I love giving demos, talks or lectures and always get positive energy from a room full of people!

Outside work, I love rowing, travelling, playing rock/jazz guitar and chasing bands on tour. 🎼 I sometimes write poetry and lyrics for (ever-)future songs :)

News

Miles beyond thrilled to announce our work on music generative models - Lyria, Dream Track and Music AI tools. Happy to have contributed to both fan engagement and creative exploration avenues, as (1) GDM tech lead for the model quality workstream leading up to the Dream Track launch and (2) core contributor to Lyria and Music AI tools, via identifying useful data signals, adding model capabilities and assessing them via human evaluation studies. Humbled by the fantastic artists who are supporting the Dream Track experiment in YouTube Shorts - check out what shorts they and the 100 creators have uploaded here - and immensely grateful for the Artist Incubator participants, who have been giving us plenty of insights and feedback for developing the Music AI tools!

Launch Nov 2023

Our intern’s project got published in TMLR - congratulations Jannik Kossen for leading this and for a successful internship in summer 2022 at DeepMind!

Publication Jun 2023

After 1 year and 7 months at DeepMind, I am now a Senior Research Scientist! Grateful for the support of my manager and for all my bright collaborators!
