Expertise

Dr. Liseth Tjin-Kam-Jet – Siemons is epidemiologist and post-doc researcher at the Persuasive Health Technology Lab, Center for eHealth, University of Twente, Enschede, the Netherlands. She studied organizational as well as health psychology and graduated with honors from the research master “Social Systems Evaluation and Survey Research”, within the track “Evaluation and Assessment in Health and Safety Psychology’”. She obtained her PhD in the measurement, modelling and monitoring of disease activity in patients with rheumatoid arthritis.

During her PhD Liseth followed a 3-month internship at the group of Prof. Dr. E. Krishnan from the School of Medicine at Stanford University (CA, USA), with whom she is still collaborating. She has been and is involved in several research projects as well as the supervision of PhD, master, and bachelor students. Also, Liseth was the main organizer of the 2nd Item Response Theory in Health Measurement conference in 2013 (Amsterdam, the Netherlands) and of the Summerschool “Big data in clinical medicine” in 2014 (Enschede, the Netherlands).

Her overall research interests and expertise lay in behavioral science, organizational psychology, health psychology, epidemiology, methodology and statistics, disease outcomes, quality of life, healthcare, eHealth, public health, health technology, and Big Data.

Currently, her research focusses on two projects:

1.

The use of Big Data for Personalized, Persuasive, and Safe Healthcare

What factors that are crucial for using and managing big data to support the growing needs for personalized and cost-effective healthcare? We want to better understand how to use data from large and complex datasets in an effective, efficient, secure and safe way to design real-time, accurate, persuasive and personalized feedback systems.

2.

ePublic Health: Developing an interactive platform for tailored risk communication to prevent non-alimentary zoonotic diseases

Developing a web-based communication dashboard (i.e. the eZoon dashboard) to reduce uncertainties and to foster individual and collective protective actions against zoonotic hazards and disasters. An adaptive Question and Answer system and e-learning game for professionals and the general public will be part of the eZoon dashboard to increase awareness, self-management via self-learning, and user-adaptive communication.
