How to pronounce Jacek Gwizdka?  How to pronounce my names? Jacek: [ˈyat͡sɛk] WAV MP3 Gwizdka: WAV MP3


I am an applied natural scientist, with a PhD and two masters’ degrees in engineering (industrial and electrical) and a postdoc in cognitive psychology. I study human information interaction and retrieval (a.k.a. interactive information retrieval, information search and retrieval) and apply methods from experimental cognitive psychology and neuro-physiology to understand information searchers and improve search experience. I am particularly interested in inferring and quantifying cognitive and affective phenomena in human information interaction from neuro-physiological signals and subsequently in creating models that relate and predict these phenomena. My recent projects investigate information relevance and quantifying the search process. I employ eye-tracking, pupillometry, neuro-physiological signals in assessment of search as learning, reading, mind-wandering and in inferring information relevance. I have a keen interest in neuroscience, philosophy, and philosophy of science.  Full_CV  |  Short Bio PDF


I believe in science and scientific evidence as a basis for rational human decision making at all levels of society. I am post-positivist and a critical realist and believe that there is a reality independent of us and an objective truth. Even if uncovering the truth may be unattainable, we can (and should) triangulate across multiple error-prone data sources to get closer to the objective reality. I engage mainly in quantitative research, but also mix it with qualitative. My readings in philosophy of science on my list of readings can shed further light on my approach to science and research.
