Biography

Timothy D. Ritchie, Ph.D., collaborates with scholars locally and internationally. He is a peer reviewer for 40+ scientific journals, publishing companies, and grant agencies and an author of 60+ peer-reviewed journal articles, encyclopedia entries, and book chapters.

In 2014, Ritchie was hired by SXU as an associate professor and was chair of the Psychology Department for seven consecutive years. He was tenured in 2017, promoted to full professor in 2020, and works full time with the Office of Institutional Research and Assessment.

Ritchie studied psychology and philosophy during undergrad. On weekends and during summers, for three years, Ritchie learned theory and research skills in immunology and neurobiology and participated in an additional fellowship in biological psychiatry and psychopharmacology.

Next, he earned a graduate clinical psychology degree (while also paying off loans) as a new hacker and apprentice of automation software engineering for a statistics company.

After more than three years in the analytic software business, Ritchie studied vision, sleep, and death as a visiting graduate student in Germany's Max Planck Institute for Neural and Behavioral Sciences.

Returning home, Ritchie worked as a psychometric analyst for an educational assessment publishing company near Chicago. The next year, he began doctoral research in social psychology, memory, and emotions with a minor in quantitative methodology.

After graduating, he began a post-doctoral fellowship in the UK. Two years later, he served as a lecturer in Ireland for five years.
