I started studying psychology at the Free University of Amsterdam. My bachelor studies (supervised by Dr. Karen Mortier) were conducted within the theoretical framework of embodied cognition. In our experiments, we utilized different mood induction techniques in order to empirically investigate their influence on selective attention in a series of computerized visual search tasks. Our theorizing was significantly influenced by considerations regarding conceptual metaphor theory and the neuropsychological valence model of hemispheric processing of emotion perception.
Subsequent to my bachelor studies, I successfully completed a M.Sc. in psychological research methods at the University of Plymouth. During my master's project, I collaborated with Prof. Simon Handley and the resulting dissertation focused primarily on the role executive functions play in syllogistic vs. belief-based reasoning (i.e., syntax vs. semantics in belief bias). Much of the motivation for our experimentation was derived from prior work on ego depletion and contemporary dual process theories of cognition. Based on this background, I acquired substantial knowledge in cognitive psychology, particularly in the domain of reasoning and decision making (e.g., in the Kahneman and Tversky research tradition).
I am intrinsically very interested in the 5-hydroxytryptamine system and its role in perception and cognition (for instance, creativity, neuroplasticity and neurogenesis). Furthermore, philosophy of science and mind capture my deepest curiosity.
Personally, I love to exchange ideas with scholars who adhere to different scientific paradigms because interdisciplinary discourse offers great intellectual stimulation and provides impetus for the development of novel unconventional ideas.

Contemporary materialistic reductionist neuroscience emanates from the working hypothesis that the underpinnings of human perception and cognition are based on electrochemical transduction. That is, electrical action potentials and chemical neurotransmission are postulated to undergird all mental processes. Interestingly, especially from a neurochemistry/biology point of view, several secondary (possibly semiotic) plant compounds have close structural relationships with various human neurotransmitters and consequently can reliably change a variety of cognitive processes (both quantitatively and qualitatively). N,N-Dimethyltryptamine (often acronymised as DMT) is a paradigmatic exemplar. Its molecular structural geometry (see Appendix) is very closely related to 5-hydroxytryptamin (Serotonin). DMT is a phylogenetically ancient molecule which is ubiquitous in the plant and animal kingdom (Smith, 1977). In its pure synthesized form, it is a white, pungent-smelling, crystalline solid. Accumulating converging evidence suggests that DMT is an endogenous neurotransmitter in the human brain (e.g., Cozzi, et al., 2009; Fontanilla, et al., 2009).
A defining criterion of DMTs psychological activity is that it affects visual perception in the most spectacular ways possibly imaginable. Its profound experiential/phenomenological effects are described as consciousness expanding, transformative, and essentially ineffable. DMT has been used in shamanistic rituals for millennia by several cultural traditions. For example, it constitutes the active chemical principle in Ayahuasca, a plant based, drinkable concoction, which is utilized by indigenous tribes in the Amazonian rainforest for divinatory and healing purposes (Metzner, 2014). Typically, the main ingredients of the Ayahuasca brew are two plants, Psychotria Viridis (which contains the DMT) and Banisteriopsis Caapi (which contains the harmala alkaloid harmine, a slective and reversible monoamine oxidase inhibitor that prevents the breakdown of DMT in the gastro-intestinal tract). Western science has just recently learned about DMT and its psychoactive effects from ethnobotanists who were able to conserve this ancient knowledge literally in the last minute because old shamanic traditions are being extinguished at a fast pace by the modern industrial world.
Compounds such as psilocin (which is a precursor of psilocybin) and DMT have chemical structures that resemble the neurotransmitter serotonin. This structural similarity allows them to stimulate serotonin-sensitive neurons. Note that the intermolecular serotonin motif is embedded in both analogous structures.
Christopher Germann and Prof. Roger Malina discuss Chris’ current work in the Cognovo PhD program, on quantum cognition which applies the mathematical formalisms of quantum theory to understanding cognitive processes. Chris is currently working on non-commutativity in decision theory, with laboratory experiments in visual decision making. He is also studying the role of the endogenous neurotransmitter DMT (N,N-Dimethyltryptamine) in perception and cognition.
Chris presented the empirical results of his psychophysics experiments at the “Science and Nonduality” conference which took place in California’s Silicon Valley.
Science and Nonduality (acronymised as SAND) provides a forum where preeminent physicist, neuroscientists, psychologists, philosophers, artists and a large, international community gather to explore and advance the new emerging paradigm that is both grounded in cutting-edge science and consistent with the ancient philosophical wisdom of nondual schools of thought (e.g., Advaita Vedanta, Mahayana Buddhism) — the deep understanding of the interconnectedness of all life.
"Imagine a multidimensional spider's web in the early morning covered with dew drops. And every dew drop contains the reflection of all the other dew drops. And, in each reflected dew drop, the reflections of all the other dew drops in that reflection. And so ad infinitum. That is the Buddhist conception of the universe in an image."
~ Alan Watts
"It really boils down to this: that all life is interrelated. We are all caught in an inescapable network of mutuality, tied into a single garment of destiny. Whatever affects one destiny, affects all indirectly."
~ Martin Luther King Jr.
Indra's net is a visual metaphor that illustrates the ontological concepts of dependent origination and interpenetration (see Cook, 1977).
SAND explores the edge where knowledge meets the unknown. SAND is inspired to develop a vibrant community of individuals who share this vision, believing the time is right for the fragmentation of knowledge that has occurred over the last centuries to give way to a new integrative paradigm in which science and spirituality reenter into meaningful dialogue – bridging an empirically responsible and non-dogmatic spirituality with a humanistic science willing to consider questions of context, perception, meaning and purpose.
„Was ich in der Natur sehe, ist eine großartige Struktur, die wir nur sehr unvollkommen zu erfassen vermögen und die einen denkenden Menschen mit einem Gefühl der Demut erfüllen muss. Dies ist ein echt religiöses Gefühl das mit Mystizismus nichts zu schaffen hat.“
Translation: “What I see in Nature is a magnificent structure that we can comprehend only very imperfectly, and that must fill a thinking person with a feeling of humility. This is a genuinely religious feeling that has nothing to do with mysticism”.
~ Albert Einstein (1979, p.132)
Chris finished his secondment at Manipal University Jaipur where he conducted emprical research under the supervision of Professor Geetika Tankha on psychophysical noncommutativity effects in cross-modal perceptual processes. In addition, the investigation focused on the concept of ego-extension from a cross-culural perspective.
Professor Geetika Tankha is Head of the Psychology department at Manipal University Jaipur, India. She holds a doctorate in psychology from the University of Rajasthan. Her major areas of research interest are individual differences, human cognition, environmental and cross-cultural psychology.
