Research scientist @ Robust Incentives Group, Ethereum Foundation.
Research in algorithmic game theory, large systems and cryptoeconomics with a data-driven approach.
04/02/2020: I joined SUTD’s Master in Urban Science and Planning Policy as Adjunct Lecturer, to teach the course of Computational Urban Analytics for a semester.
01/01/2020: I joined the Ethereum Foundation as a research scientist in the newly-formed Robust Incentives Group. The team will explore mechanism design and protocol security from the standpoint of algorithmic game theory and economics, in the context of blockchains (in particular, Ethereum…)
07/12/2019: On November 16th, I joined a team at Yale-NUS in the Open Climate Collabathon, held in various places around the world over two weeks. We worked out an incentive system to motivate accurate data reporting, with modules providing a secure environment for whistleblowers to report corrupted data, analysing actor commitments and checking commitment fulfillment on private, encrypted data. See more details here! We went on to share the most innovative approach award with another team, who worked on consumer disclosure and sustainable supply chains. Our work was presented during the UNFCCC COP25 by Ying Tong and Angel.
04/07/2019: I attended the 20PoA conference, celebrating 20 years of Price of Anarchy since E. Koutsoupias and C. Papadimitriou’s paper, Worst-Case Equilibria. It was held in TU Creta, near the beautiful city of Chania. I presented a poster on our work linking inequality and Price of Anarchy, which was also discussed during Christos’s keynote.
04/06/2019: I defended my PhD thesis today, Efficiency, regret and inequality in decentralised systems! It takes a look at the behaviour of a large real system, Singapore’s mobility network, and provides models, experiments and data about the impact of decentralisation on effiency and inequality. Find a Twitter thread here where I expand on my oral presentation and my final thesis submission.
11/04/2019: hackingresear.ch, a website featuring visual explorations of economics and computer science for blockchains, is now live! It is a joint work with Sacha Yves Saint-Léger.
15/03/2019: I attended the STACS 2019 conference where I presented our paper, Wealth inequality and the price of anarchy.
10/03/2019: I participated in ETHParis where my team produced a finality inspector for CBC Casper, with a visual essay explaining the theory behind it.
09/12/2018: My team was one of 6 finalists at ETHSingapore, one of Ethereum’s global hackathons. We worked on an extension to the popular Py-EVM, a Python implementation/client to the Ethereum Virtual Machine. Our extension allows for cross-shard communication and transactions, an important piece of infrastructure for Ethereum’s planned sharding design. Our design follows the specifications of CBC Casper, for which I gave an intro here.
02/11/2018: I attended Devcon iv., Ethereum’s fourth developer convention, in Prague. The conference itself had some great talks (I am hoping to share the videos once they appear online), but the best part was the giddy excitement everyone has for the project and meeting up with fascinating people.
21/09/2018: With other SUTD ESD graduate students, I co-organised our first SummerCon, where first and second year graduate students present results from their summer projects. We had a poster session including my latest work and a great talk on the surprising uses of regret in Operations Research.
08/09/2018: I attended RCon3 in Berlin, RChain’s crypto conference during the Berlin Blockchain Week. Great meeting a lot of teams working on cool projects.
02/06/2018: I spent a fun afternoon at Golden Mile Tower, attending John’s workshop on his experiences working and designing with bamboo. We made a bamboo-based bus stop (with a few load-balancing issues…)
24/02/2018: I am attending the Ethereum meetup in Bangkok tomorrow. My advisor Georgios is giving a talk on formal foundations of cryptoeconomics.
26/09/2017: Our paper Routing Games in the Wild: Efficiency, Equilibration and Regret (Large-Scale Field Experiments in Singapore) was selected for WINE 2017 in Bangalore.
17/07/2017: This week I am participating in the Fairness, Accountability and Transparency in AI at NUS. I gave a talk on our latest work in progress, How bad is selfish routing in practice?
11/07/2017: I called in to Tehran for a Machine Learning introduction, as part of the Global Summer School (GSS) of the Institute for Advanced Architecture of Catalonia. You can find my slides for the talk here. Lots of questions on how to apply the methods to architecture!
10/07/2017: This week I am participating in the Science, Technology and Policy workshop at NUS, in the Smart Mobility team. We suggested Singapore should add more dedicated cycling lanes (or tunnels), thought about policy implications of the upcoming ERP2 system and designed a chairlift system to be built on top of existing HDBs to connect to MRT stations.
25/05/2017: Opened my new website!
