About Patrick
Patrick has a background in experimental psychology and cognitive neuroscience and completed his PhD at Melbourne Neuropsychiatry Centre at The University of Melbourne, under the mentorship of Professor Ben Harrison. Using lab-based behavioral studies and 7-Tesla fMRI, his doctoral research used novel iterations of the ‘Pavlovian conditioned inhibition’ paradigm to characterize safety learning, the process by which a stimulus comes to predict the absence of threat. He is interested in integrating principles of associative learning theory with contemporary behavioral neuroscience methods (e.g., neuroimaging), with the aim of producing richer brain-based characterizations of behavioral processes, including those implicated in the pathophysiology & treatment of psychiatric illness (e.g., PTSD, anxiety disorders, & others). Outside of research, his interests include music, film, books, travel, & meditation.
About Elizabeth
Elizabeth completed her PhD in Psychology at Texas A&M University under the mentorship of Dr. Annmarie MacNamara. Her doctoral research used EEG/ERPs and fMRI to examine cognitive and affective processes underlying anxiety and depression. Elizabeth is interested in leveraging computational neuroscience and neuroimaging to better understand how emotional learning and memory is implicated in PTSD and anxiety, with the aim of contributing to better brain-based characterizations of these disorders. In her spare time, Elizabeth enjoys spending time with her dog, fiber arts and paper crafts, and reading.
About Alyssa
Alyssa completed her PhD in Neuroscience at Emory University under the mentorship of Dr. Jennifer Stevens at the Grady Trauma Project. Her doctoral research focused on sex differences and longitudinal changes in emotion-related brain function following traumatic events, and utilized functional magnetic resonance imaging (fMRI) to investigate the effects of exogenous estradiol on fear extinction learning in women with PTSD. She is interested in the use of virtual reality and neuroimaging to understand emotional learning, with the goal of characterizing brain processes implicated in psychopathology (PTSD, anxiety). Alyssa’s hobbies include hiking, all sorts of art, playing the piano and ukulele badly, reading, video games, and hanging out with her dog, Mabel.

Nicole Keller
About Nicole
Nicole Keller, a Costa Rican native, received her Bachelor of Science in Neuroscience and a Business Foundations Certificate at the University of Texas at Austin. She recently received her PhD in Neuroscience from the Institute of Neuroscience. Nicole’s research interests include, but are not limited to, the opposing roles of reward and fear in human learning and memory–particularly, the effect of reward on fear extinction. Through the use of psychophysiology and neuroimaging methods, she is investigating how the presence of a reward during fear extinction can enhance the function and efficacy of a safe memory, and further prevent relapse of fearful behaviors. Outside of the science, she thoroughly enjoys being in the presence of her cat, Ivy, buying plants, and learning French.
About Carola
Carola received her Ph.D. in Experimental Psychology, Linguistics, and Cognitive Neuroscience at the University of Milano-Bicocca where she began studying the neural mechanisms underlying creativity. Carola worked as a postdoctoral fellow at Northwestern University and the Shirley Ryan AbilityLab in Chicago, where she narrowed her interest to studying idea generation, specifically insight problem-solving (the “Aha!” moment). Carola’s work aims to understand the following: the role played by reward (and the dopamine system) in creativity and insight problem-solving; the involvement of the vision system in idea generation; and the role of the right anterior temporal area when people have creative insights. Carola contributed to pioneering the “accuracy effect” associated with “Aha!” moments, demonstrating that the feeling of certainty that accompanies creative ideas is warranted by high accuracy. Her work counts the first Italian versions of the Compound Remote Associates problems and the Rebus Puzzles, enabling researchers to investigate the insight problem among Italian speakers. She has experience working with TBI, Parkinson’s and neglect patients, and has mastered several techniques of research such as eye-tracking, imaging, and brain stimulation.
