I am a research associate supervised by Prof. Daniel Paulusma and Prof. Iain Stewart, funded by EPSRC grant EP/K025090/1
"Detecting Induced Graph Patterns".
I work
mostly on graph structure and graph algorithms in restricted graph classes (from both a
parameterized and non-parameterized point of view).

I completed my PhD
in 2012, supervised by Prof. Vadim Lozin.
After that, I worked for six months as a research associate supervised by Prof. Daniel Paulusma
and Dr.
George Mertzios, funded by EPSRC grant EP/G043434/1
"Algorithmic Aspects of Graph
Coloring".
I then worked for six months as a research associate supervised by Prof. M.
Demange, funded by ANR grant TODO ANR 09-EMER-010
"Time Versus Optimality in Discrete Optimization".

Academic Responsibilities

I teach the LSEPI (Legal, Social, Ethical and Professional Issues) sub-module, which forms part of the COMP2201 Group Project module.

I previosuly taught part of the Logic and Discrete Structures sub-module of COMP1021 Mathematics for Computer Science.

I organised the ACiD Research Seminars and the Computer Science Junior Seminars.
