Dr. Dalmaijer is a cognitive neuroscientist who revolutionized eye tracking with his PyGaze toolbox. This open source eye tracking software has made eye tracking affordable for nearly any research laboratory. Although Edwin's software can be used to interface with expensive (>$30k) eye trackers, it also wraps around the APIs of cheap, consumer-grade eye trackers intended for gamers. As Dr. Dalmaijer has shown in his careful testing, these cheap eye trackers are sufficient for many research applications. PyGaze has allowed the PEEP lab to send eye trackers all over the US to collaborating labs and even a psychiatric hospital.
Dr. Dalmaijer designed our gaze-contingent operant conditioning study and recently presented the work at the European Conference on Eye Movements. You can find his invaluable book on programming in Python for psychologists here, which is a must-read for any graduate student or advanced undergraduate in psychology.

Dr. Morris conducts transdiagnostic research on stress and pain
disorders, with a focus on racial disparities in mental health. He and
Dr. Armstrong are conducting eye-tracking research on the
nature of racial differences in disgust sensitivity and
contamination-based OCD. They are also conducting research on
attentional biases in PTSD and chronic pain disorders. In 2017, Mira
Engel, a PEEP lab member, spent a summer in Dr. Morris's lab
conducting research and learning pain assessment methodology.
Thröstur Björgvinsson & Courtney Beard
McLean Hospital / Harvard Medical School
Dr. Björgvinsson directs the Behavioral Health Partial Hospital Program at McLean Hospital and is a pioneer in the intensive treatment
of OCD. Dr. Beard directs the research program at the partial hospital
and develops novel cognitive interventions for anxiety disorders. In
2017, Dr. Armstrong and three PEEP lab members (Rachel Leiter, Hannah
Bouwman, & Trevor Press) visited McLean to set up an eye-tracking
system. In 2018, Dr. Armstrong and PEEP lab member Sara Federman are
returning to McLean for 9 weeks to complete an eye tracking project on
anhedonia in depression with Drs. Beard and Björgvinsson.
West Virginia University
Dr. Steinman is a clinical psychologist who studies anxiety-related
disorders and OCD. She and Dr. Armstrong recently began collaborating on eye tracking research that will explore the habituation of attentional biases for fear and disgust. Dr. Steinman also has some
interesting ideas for studies on conceptual reorientation that Dr. Armstrong is excited to run with her.
Dr. Stewart is a clinical psychologist who studies suicide and self-injurious behaviors in youth. He and Dr. Armstrong successfully applied for a small grant from Canada's Social Science and Humanities Research Council to create an eye tracking station in Dr. Stewart's lab. PEEP lab member Siri Danielson worked with Dr. Stewart during the summer of 2019 on a project using eye tracking to assess risk factors for suicide.
Dr. Armstrong completed his supervision under the excellent mentorship of Dr. Olatunji. He and Dr. Armstrong continue to collaborate and recently conducted a meta-analysis of over 100 studies examining the role of disgust in anxiety-related disorders.
Dr. Treadway is a clinical psychologist and neuroscientist studying
the roles of decision making and dopamine in depression. In 2016, PEEP lab member Anneka Soenstram spent a summer learning neuroimaging methods in Dr. Treadway's laboratory and then conducted her thesis research in the PEEP lab exploring spontaneous blink rate (measured by an eye tracker) as a proxy for striatal dopamine. PEEP lab members also used Dr. Treadway's EEfRT task, in conjunction with eye tracking, to parse components of reward processing.
