Sarika is a PhD student at Queensland University of Technology whose research interests involve the application of mathematical modelling techniques to ecological questions. Under the supervision of Professor Michael Bode and Dr Matthew Adams, she is working on the mathematical modelling of regime shifts in the Antarctic and sub-Antarctic regions. She aims to collect data on previous regime shifts in the area, develop new mathematical models, optimize them and use them to predict future regime shifts. It is expected to contribute to future decision-making for the management of Antarctica, stall further deterioration of its ecosystems and safeguard the same for future generations. Sarika has a background in both pure and applied mathematics with prior research experience in inverse and ill-posed problems.
