I am an SNF BRIDGE fellow in the group of Srdjan Capkun at ETH Zürich and IC3.
Previously, I did research at Cornell Tech under the supervision of Ari Juels, and spent some time in industry at Google and Open Systems.
I am interested in security, applied cryptography, and blockchains / cryptocurrencies.

GasToken
GasToken is a new, cutting-edge Ethereum contract that allows users to tokenize gas on the Ethereum network, storing gas when it is cheap and using / deploying this gas when it is expensive. Using GasToken can subsidize high gas prices on transactions to do everything from arbitraging decentralized exchanges to buying into ICOs early. GasToken is also the first contract on the Ethereum network that allows users to buy and sell gas directly, enabling long-term "banking" of gas that can help shield users from rising gas prices.
LibSubmarine
LibSubmarine is an open-source smart contract library that makes it easy to protect your Ethereum smart contract against front-runners by temporarily hiding transactions on-chain.
proveth
The proveth open-source project consists of a smart contract library for verifying Merkle-Patricia-Proofs and an off-chain proof generator. This enables Ethereum smart contracts to trustlessly consume otherwise inaccessible data such as transaction history.
thehydra.io
The Hydra framework enables Ethereum smart contracts to administer their own decentralized bug-bounty programs encouraging the disclosure rather than the exploitation of vulnerabilities. To power the Hydra, a brand new technique called N-of-N version programming inverts the old fault tolerant software idea of N-Version programming (NVP). While NVP emphasizes availability, NNVP requires consensus among its implementations to emphasize integrity. Each Hydra contract is composed of several subcontracts, or heads. These heads can be written in different languages, compiled with different compilers, and/or created by independent developers. By making sure all these heads agree at every step of computation, Hydra can detect potentially security-critical bugs before exploitation. These include compiler errors, developer errors, and language specific flaws.
