Anam Ahmed, MSc

Junior Consultant/ Researcher

Anam Ahmed, MSc, studied Biomedical Sciences at the Vrije Universiteit in Amsterdam. A strong interest in creating and facilitating bridges between commercial business and the life sciences/healthcare field led her to the Master’s program Science and Business Management at the University of Utrecht. During her graduation project, she focused on analysing growth opportunities driven by the strategic objectives of a fast-growing consumer healthcare company. Furthermore, she conducted a feasibility study on the implementation of a medical device in the Dutch market, which included extensive qualitative and quantitative analyses and designing a valuation model. After graduating, she started working as a consultant focused on strategy, finance and analytics. Her passion for health economics and market access made her switch to a career with a stronger focus on life sciences and healthcare innovation. At Panaxea, Anam uses her scientific background and experience in consultancy to support innovative projects.

Anne Voermans, MSc (ir.)

Junior Consultant/Researcher

Anne Voermans, MSc (ir.), graduated as a Medical Engineer from the Eindhoven University of Technology, which relates to her interest in medical research – especially when innovations are involved. During her Master’s program, Anne worked on (clinical) studies initiated by clinicians throughout different hospitals in the Netherlands. Her research was mostly aimed at orthopaedic biomechanics. Besides academic skills and practice, Anne has experience working and collaborating with professionals of both different scientific and medical backgrounds. Her most extensive research project concerned bone stiffness calculations during fracture healing. A novel high-resolution CT technology was feasible to capture longitudinal changes in bone stiffness. However, it remained unclear whether more widely available conventional CT scanners are applicable to this end as well. In general terms: is the novel technique more feasible than the current golden standard? As an HTA consultant and researcher at Panaxea Anne is still focused on this question from a cost-effectiveness perspective in each project.
