I'm working on channel coding, i.e., I'm designing algorithms that encode and decode data such that errors occuring during transmission of the encoded data can be corrected. In particular, my research interest encompasses

• Coding for Optical Communications: In fibre optical communications, data rates are extremely high, limiting the computational complexity per transmitted bit severely. Codes must therefore be efficiently decodable in a parallel, while still correcting many errors. I'm designing decoders suited for optical transmissions, that aim to trade off between complexity and performance.
• Asynchronous Communication Systems: When transmitter and receiver are not synchronized, the channel coding problem grows more complex and strategies are needed to deal with both transmission errors and the asynchronicity simultaneously.
• Bounds in the Short Blocklength Regime: For asymptotic (infinite) blocklengths, the capacity of the channel limits the achievable rate. When the blocklength is short (e.g. 100s of symbols), a closed form term for the achievable rate is not possible. Still, bounds on the achievability and non-achievability of transmission rates can be found.

If you are a student interested in the aforementioned topics, feel free to contact me for a thesis.
