Aprilia, PhD

Hi, my name is Aprilia :)

I am a researcher working on the processing and characterization of metal alloys. I am interested in advanced manufacturing technologies and I am currently working as a research fellow in Assoc Prof Zhou Wei's group in Rolls-Royce@NTU Corporate Laboratory, Singapore. I received my PhD in 2021 under the supervision of Assoc Prof Tor Shu Beng and Assoc Prof Seet Gim Lee, Gerald in Singapore Centre for 3D Printing, Nanyang Technological University (NTU), Singapore.
