Kristin Luttik, PhD Student

Kristin earned a bachelor’s degree in Aerospace Engineering at Delft University of Technology in 2010. After a year of travelling and gaining work experience as an engineering intern, she moved to Scotland to study for her Master’s degree in Sustainable Energy Systems at the University of Edinburgh; which she was awarded with distinction in 2012.

In October 2017, he started his PhD project within VOILAb on gust alleviation by morphing blades for wind and tidal turbines. The aim of the project is to develop a novel intelligent blade that through a high-frequency morphing will cancel fatigue loads and enhance energy harvested. His specialist expertise includes impulse method and low order models.

 

Geethanjali Pavar, PhD Student

Anjali earned a masters in Computer Science from Imperial College London, followed by a masters in Environmental Change and Management from the University of Oxford. She later converted to engineering through a masters in Advanced Mechanical Engineering from Cranfield University, before joining the CDT in Wind and Marine Energy Systems, led jointly by the University of Strathclyde and the University of Edinburgh. In 2019, she started her PhD with VOILAb and is studying the interaction between vortex gusts and wings. The aim of her project is to improve understanding of the underlying physics through a combination of analytical modelling and experimental work.
