About us Practical matters

Staff members with discipline Statistics & Probability

Academia develops at the interface of different fields. This is one reason why the University of Groningen is home to a wide range of fields, each with a great number of subject specialists. The overview below, which is based on a standard categorization of fields, will help you find the right expert for each field. If you cannot find the expert you are looking for in this list, try searching via a related field or faculty; you may find him or her there.

Overview of all disciplines

At the faculty BSS, I am employed on the chair Applied Statistics and Data Visualisation. 
My research focuses on the development of statistical models for applications in the social sciences. These models often contain dynamic or longitudinal components. Furthermore, I’m interested in science communication - for which data visualisation plays a key role - and the improvement of scientific practice in general.

Furthermore, I'm Director of Research of the Heymans Institute for Psychological Research.

One of my main research themes involves analyzing intensive longitudinal data. Particularly, I am interested in formulating statistical models that describe the between-individual differences that are present in such data. I often employ and develop clustering models for intensive longitudinal data to identify more homogeneous subgroups of people.

Another core interests lies in the implementation of novel statistical methodology into freely available software. The code to estimate the statistical models that are discussed in my research projects can be found on the Open Science Framework or GitHub (links can be found below).

I also research how statistical models are used and interpreted by empirical researchers.

NWO-VENI laureate Prof. Hak and his multidisciplinary team have supervised >30 PhD theses on the validity of scientific statistical and epidemiological causal design methods to assess (side-) effects of drugs and vaccines using Real-World Big Health Care and Biobank Data. Scientific methods consider a variety of designs such as case-control, cohort, case-only, sibling designs, instrumental variable analysis, propensity score analysis often in combination with RCTs, meta-analyses and Individual Patient Data designs. His scientific work led to >400 peer-reviewed publications till 2021 (Web of Science H-index 44, >8,000 citations). As leader of the PharmLines Initiative,  a public-private collaboration between Lifelines BV-UMCG-RUG, he initiates and co-supervises research in the area of Precision Medicine with linked biobank, genetic, clinical, pharmacological and health care data of >80,000 persons from the Northern region. Topics mainly concern the pharmaco-epidemiology of preventive medications as well as vaccinations. In addition, his team supports the societal impact by studying the optimal methods to implement innovations in the area of sustainable drug applications and  vaccination strategies (e.g. drug repurposing, data science technologies to support optimal drug use, development of infection risk profiles and vaccination passport).

Prof. Hak is program director of the two-year Groningen Research Master Medical Pharmaceutical Sciences. As a director he implemented innovations regarding the extension of research tracks including Pharmaceutical Design & Engineering, Drug Toxicology &Translational Technologies and Pharmacoepidemiology & -Economics. With these tracks the complete drug development cycle can be studied within MPS. He further introduced a strong mentorate for students, monitoring of research projects, clear selection criteria for examiners and committee evaluations of research projects, which resulted in a Top-label in 2017 and 2019 by the influential Dutch Keuzegids (MPS belongs to the top-10% best master educations in the Netherlands). As educational director Pharmacy (>100 faculty) he applies his broad expertise to lead the cluster Pharmacy, also in close collaboration with sister Faculties.

My main research theme involves explaining observed data, typically resulting from psychological research, with a meaningful and concise model. This task becomes really challenging when multivariate and/or longitudinal measurements are to be modeled jointly. Specific methods of interests concern the development and evaluation of 1. data reduction modeling (e.g., principal component analysis); 2. latent variable modeling (e.g., exploratory factor analysis); 3. cluster modeling (e.g., mixture analysis); 4. modeling for test construction (e.g., GAMLSS model for test norming).

Postdoctoral researcher
My main research interests lie in the development of patient-centered diagnostic and risk-prediction models for use in psychiatric practice. More specifically, my research focuses on the methodological and statistical approaches that are needed to develop such models in evidence-based research. My methodological/statistical interests lie in (1) Modern Psychometrics, (2) Modeling of (intensive) longitudinal data, (3) Prediction Modeling and (4) Machine Learning.
As part of my job, I work as a statistical advisor for researchers in the UMCG Department of Psychiatry and in affiliated mental healthcare institutions.
