Darya Melnyk

I am a postdoc in the Internet Network Architectures Group at TU Berlin, working with Stefan Schmid. Before joining TU Berlin, I was as a postdoc at Aalto University. There I worked in the Distributed Algorithms Group with Jukka Suomela. I received my PhD in Computer Science from ETH Zürich in August 2020 under the supervision of Roger Wattenhofer.

Research

In my research, I focus on various problems in theoretical computer science, in particular on distributed graph and communication algorithms. I am interested in developing fault-tolerant distributed algorithms that can withstand crash failures or Byzantine adversaries. I also like to investigate the limits of such systems, by trying to find lower bounds and derive impossibility results. Besides these topics, I enjoy working on online algorithms (with and without delays), voting theory as well as on finding possible connections between the different fields.
