Degree: Associate's Degree
Major:Brand Management
A diploma covering areas such as branding, marketing, management, new product development. How a brand can be developed and made a successful brand.
The University of Melbourne Parkville , Victoria, Australia
02/2016 - 12/2019
Degree: Doctoral Degree
Major:Food Science
Minor:Sensory Science, consumer behavior
During the PhD, I found that a joint application of both traditional and novel sensory techniques provide valuable inputs to understand consumer perceptions, which include self-reported and physiological responses. Furthermore, artificial neural networks can be used to analyze hidden nonlinear patterns which maybe disregarded in traditional parametric studies.
