Pharmaceutical drug delivery devices generally involve clever little mechanisms made of plastic in large numbers. Making these work properly can be very challenging. Let me help you with this: 1. Conceiving mechanisms that will be reliable. 2. Analysing and predicting the reliability issues the mechanism will face. 3. Investigating and solving issues found during prototyping. My unique approach brings together modeling the sources of variation, and measuring the performance in real life - combining theory and empirical data leads to insights and solutions
