Personal profile

Research profile

Llewellyn (Lew) van Zyl is an Assistant Professor in work and organisational psychology with the Department of Human Performance Management at the Eindhoven University of Technology (TU/e). His research aims to enable people to feel good, function well, and perform better at work. It is concerned with understanding the factors that enhance mental health and performance and how they can be developed through online enabling interventions (OEIs). At its core, his research aims to understand if, how and why online enabling interventions could optimize human processes. In practical terms, his work employs a strengths-based approach to diagnose, optimize, and develop individuals' mental health and performance through online platforms. Building on the empirical and theoretical foundations generated within the Human Performance Management (HPM) group, his work aims to (a) assess and model the psychological mechanisms underpinning employees’ mental health, wellbeing and performance (assessment: c.f. Van Zyl, Olckers & Roll, 2020; Van Zyl, van Oort, Olckers & Rispens, 2019), (b) how these states can be developed in a scientifically sound, sustainable and cost-effective manner through digital channels (OEI content: c.f. Stander & Van Zyl, 2019; Van Zyl, et al., 2020) and (c) aims to understand the elements underpinning effective OEI design (online intervention methodology: c.f. Kelders, Van Zyl & Ludden, 2020).
