I am a machine
mainly interested in theoretical aspects of sequential decision making.
I mainly work on online optimization,
bandit problems, and reinforcement learning theory. My general research
to bring theory and practice closer together by proving theoretical
performance guarantees of practical algorithms and making principled
learning algorithms more accessible to practicioners.
I'm always looking for PhD students to work with me in Barcelona. Please get in touch if you're interested.
You might want to
out my CV to get
a better picture of what I've done professionally so
If you're not sure
about how to pronounce my first name, please check
out this page.
story is that you basically have to forget about pronouncing the "l"
(i.e., "ly" pronounces as "y"), and both G's are hard (as in the
English word "get").

- Busy summer: I'll be visiting Google Brain Zürich for 3 months starting in July! During the same period, I'll also be serving as an area chair at NIPS'18, so not much holidays for me this summer. 2018. 06. 05.
- Paper on iterate averaging accepted at COLT'18! You can also catch me talking about this work at this workshop at UPF/BGSE and at ISMP'18. 2018. 05. 02.
- Just back from an amazing learning thery workshop in Montreal! All talks including mine are now online. 2018. 04. 28.
- I'm a recipient of the “la Caixa” Junior Leader fellowship. In related news, I'm looking to hire a postdoc, so please get in touch if interested in doing some (reinforcement) learning theory in Barcelona! 2018. 03. 22.
- Together with Vicenç, I am co-organizing
on Lanzarote (Canary Islands), collocated with AISTATS'18. It's a wonderful
location and, as always, the conference has a fantastic PC, led by the
chairs Mehryar Mohri
Sridharan. Please consider submitting a paper and attending! 2017. 10. 18.
- One paper
accepted at NIPS'17,
thanks to my amazing coauthors: Nicolň, Claudio, and Gábor! 2017.
- Just back from COLT'17 where I
received an award
for my superbly shambolic talk! (Update: video
now online!!) I also gave another talk at the Learning
Theory workshop at FOCM'17.
- Two new papers out! One at COLT'17, another at ICML'17. I'm also set to give talks
at a Deep Learning
Workshop at Google Zürich
and an ICML workshop on Picky
I'm not going to ICML after all, Michal will
replace me at the workshop!). 2017.
- I just came back from a workshop on the "Theoretical
Foundations for Learning from Easy Data" organized at the Lorentz Center
of Leiden (Netherlands). I gave a tutorial on all the known ways of
going beyond worst-case performance guarantees in bandit problems.
Check out the slides here! 2016. 11. 13.
- We are organizing EWRL 2016 on the
weekend preceding NIPS 2016
in Barcelona with Vicenç and Csaba—please submit
your recent work on Reinforcement Learning! 2016.
- All these years of reviewing finally paying off! I
have received an "outstanding reviewer award" from ICML'16 and a "blue ribbon" for
outstanding reviewing from IJCAI'16.
- New year, new papers! One at AISTATS 2016, another in JMLR. In other news, I'm attending the DALI'16 meeting again,
this time invited to speak at the Reinforcement
Learning workshop organized by Csaba and Yasin. 2016.
- Going to NIPS
2015! I have one
paper in the main program and am also invited to give a talk at the
Faster from Easy Data II workshop organized by Tim van Erven and Wouter Koolen.2015.
- This Fall, I will be joining the AI
group at the Universitat Pompeu
Fabra (Barcelona) as a postdoc supported by the UPFellows grant. 2015.
- Two papers accepted! One at COLT 2015, another
at the IEEE
Transactions on Information Theory. Preprints here.
- I will be serving on the program committee for ALT 2015.
It's a very good conference at a beautiful location, so please consider
submitting your work—I'm looking forward to reviewing some good papers!
- I got invited to the DALI'15 workshop on Learning Theory,
organized by Nicolň
Cesa-Bianchi and Ulrike
von Luxburg. 2015.
- I'm spending a few days at the University of Alberta
with my former advisors Csaba
and Andris before going to
NIPS. Also giving a talk about one of my NIPS papers! 2014. 12. 03.
- I gave a talk at the AI
group at the Universitat Pompeu Fabra, Barcelona. Fun times, thanks
for inviting me, Vicenç!
- Talk at the LSOLDM
2014 workshop! I saw some cameras around so there's probably gonna
be a video released soon. 2014.
- Three papers
accepted to NIPS 2014!
