About H.A.W.M. (Harm) Tiddens, Prof.

Introduction

What is driving me?

To identify innovative developments that can improve the life and care of patients and to implement these developments into the clinic.

Lead motto

Learn nothing, and the next world is the same as this one, all the same limitations and lead weights to overcome. (Richard Bach, Jonathan Livingston Seagull, 1972).

I started working in structure-function research in 1992 doing my PhD with Professor Paré (Vancouver Canada). Ever since, I have worked on integrating structure-function information for improved diagnosis and monitoring of lung diseases. For this reason, I have systematically worked since 1996 on research for the validation of chest CT as a sensitive outcome measure for CF and other lung diseases. My joint position at the departments of Pediatric Pulmonology and Radiology allows me to bring together the best of function and structure worlds. In addition, in my Erasmus MC Lung Imaging Group (ELIG) there is participation by the Bio Imaging Group Rotterdam (BIGR), allowing a strong research program focused on automated analysis of chest images. Furthermore, in 2014, I founded the Lung Analysis core laboratory, which is executing image analysis for multiple clinical studies. Finally, ELIG has been instrumental in standardizing chest CT acquisition in over 40 CF centers worldwide to allow the use of chest CT as an outcome measure in clinical studies. In addition to our CT-related research, we have a development program focused on the use of chest MRI for combined assessment of lung function and structure.

Field(s) of expertise

Research for the validation of chest CT and MRI as a sensitive outcome measure for CF and other lung diseases such as BPD, Asthma, PCD, CLA, etc.
