I am a Ph.D. student at Purdue University, and I am currently supervised by professor Aniket Kate and professor Mikhail Atallah. My research focuses on the study of cryptographic primitives that offer a real-time trade-off between security and performance, and the other research direction is to combine the use of trusted execution environments (TEE) with existing privacy-enhancing techniques to design a database system that offers efficient private access to resource-constrained clients.

"My gratitude goes to Pedro Moreno-Sanchez for introducing me to this great program. Under his patient supervision and his technical insights, I was able to learn a lot more about blockchain areas. More importantly, the program allows me to meet lots of wonderful people at the TU Wien security and privacy (S&P) group. The team had shown me that it is important to have fun while doing research. Finally, I would describe my internship experience as an "awesome situation", and I would strongly suggest others to apply for this internship because of the city and the people there in TU Wien S&P group.

Since October 2016, I am a PhD student in the CryptoLUX group in the University of Luxembourg with Alex Biryukov as my advisor. I've been working on vulnerability detection in Ethereum smart contracts and on network-level privacy attacks on Bitcoin and related cryprocurrencies. Prior to my PhD studies, I worked in an information security company, helping develop a code analysis tool. I'm also hosting a popular podcast about blockchain technologies in Russian.

"At TU Vienna, I had an incredible opportunity to dive deep into the internals of the Lightning Network. This payment channel network for Bitcoin is one of the most developed projects of this kind, yet many security and privacy questions remain unanswered. Building upon the expertise of SecPriv group in this field, we came up with novel ideas regarding certain aspects of Lightning network, which hopefully would help it become more robust and privacy-preserving. I enjoyed my time in Vienna! This beautiful city, apart from a stimulating research environment, has plenty of cultural and natural landmarks to explore."

Since November 2016, I am a PhD student in the Applied Cryptography Group at FAU Erlangen-Nuremberg where Dominique Schroeder is my advisor. Prior to my PhD studies I have published in the area of System Software Engineering (SOSP'11), Coalgebraic Modal Logic (CONCUR'16) and Anonymous Communications (RAID'13). I have been an intern researcher at UC Santa Barbara with Chris Krugel and Giovani Vigna in 2012 and at TU Vienna with Pedro Moreno Sanchez and Matteo Maffei in 2018. Outside academia, I am a Debian Developer and have contributed to free software projects including the git version control system and the linux kernel.

"The time in Vienna gave me the opportunity to venture into the field of payment channel networks. Working with Pedro and Matteo provided a fresh perspective on the field and allowed to build on the experience of the team at TU Vienna. It was fascinating to see the group grow around me in the only three months I spend there. Finally I can really recommend living in Vienna, at least for some time. They even have hammocks in public parks there! Perfect for reading a paper (or a book)."
