Research

Intelligent behavior is the result of multiple thought (or cognitive) processes. I study how the brain manages to coordinate these processes.

In the past, I have used a variety of neurophysiological and behavioral methods in humans and animals (with Professor Larry Snyder at Washington University in St.Louis). I consider the contributions to the characterization of monkey executive control as some of my most important work. Currently, I am applying the insights from this research in human cognitive psychology.

In my current work, I use mental chronometry to characterize how people coordinate cognitive processes. I use a variety of experimental tasks, including the task-switching paradigm. Some of my work focuses on a better understanding "executive dysfunction" in people with neurological problems and mental disorders; some of my work looks at response-time distributions in task-switching paradigms; and some of my work addresses individual differences in a variety of tasks requiring visuo-spatial attention.

Further, I am carrying out a number of studies into individual differences. The topic of "Individual differences" is one of the core areas of psychological research. It addresses the question of how people differ in a thought and behavior, and what causes these differences.

Knowledge Transfer

Knowledge transfer is a key element of university policies. It is mostly about transferring knowledge beyond the ivory tower of the university campus. I have contributed in various ways.

I contributed to a documentary on Ketamine, currenlty being rolled out throughout European cinemas. Click here to watch the trailer.

Further, I write for educational publications for British A-level students, as well as in sharing my open-source software project "PsyToolkit" via the Internet (see the software section below).

Below is a list of some of my educational publications:
