Giselle Hsiang Loh is a PhD candidate in the Institute of Materials and Manufacturing at Brunel University under the supervision of Dr. Eujin Pei and Professor David Harrison. She has an honours degree in Product and Furniture Design and a Master’s degree in Fashion and Textiles. Her research focuses on 4D Printing (4DP), Functionally Graded Additive Manufacturing (FGAM) and Thermo-responsive Textiles.

Research Title:

The application of 4D Printing for thermo-responsive textiles.


This research investigates the differences between 4D Printing and Functionally Graded Additive Manufacturing (FGAM) and proposes a material selection framework for commercially available shape memory polymers to create shape-changing textiles when subjected to changes in temperature.

Giselle was a Teaching Assistant at Brunel University, responsible in Computer-Aided Design (SolidWorks) and Graphic Communication (Adobe Photoshop, Illustrator and InDesign). She currently works as a Research Assitant for funded projects.
