Dr Golnaz Badkobeh
Staff details
Golnaz is a Senior Lecturer in Computing and the Director of the Postgraduate Research. She is also the gender equality lead of Computing.
Prior to joining Goldsmiths, Golnaz was a Leverhulme Fellow at the University of Warwick. Her project titled " Scalable Indexing and Compression: Algorithms and Combinatorics".
Golnaz held a postdoctoral fellowship in Evolutionary Algorithms at the University of Sheffield in 2014/15, where her work focused on aspects of random search and structured population search.
Golnaz's research has two main themes: combinatorial aspects of repetition in sequential data, and algorithmic and data structural problems in string processing. Her most significant research contribution to date is a series of intricate combinatorial results concerning pattern avoidance and strong constraints on strings. This is of crucial importance in data science in particular for designing efficient pattern matching methods and text compression techniques.
