Research Interests: I am interested in understanding how brain networks facilitate cognition.
About me: I like hiking and most things that involve the outdoors.
Marshall Green
E-mail: marshall.l.green@outlook.com
Research Interests: I am interested in perceptual decision-making and metacognition. To study these topics, I combine psychophysics and computational modeling to test and develop theories of perception. My recent work has been focused on motion and orientation perception, summary statistics, and visual confidence.
About me: I earned my Ph.D. in Cognitive Science from Mississippi State University where I researched visual perception and visual working memory. I am married to a wonderful woman named Jenn, who is a talented graphic designer. My hobbies include playing violin, cooking, photography, and hiking.
Yi Gao
E-mail: yi.gao0525@outlook.com
Research Interests: I am interested in understanding human visual perception, including various visual effects such as adaptation, perceptual learning and ensemble coding. I am also interested in how other sensory modalities interact with vision.
About me: I like playing Werewolf games and Catan. I also love watching professional gamers playing PUBG Esports.

Sean Zheng
E-mail: seann0820@gmail.com
Research Interests: I am interested in how people become aware of themselves and the external environment. I am also interested in how people metacognitively monitor and control their own decision-making processes. I would like to use behavioural experiments, multimodal neuroimaging methods and computational models to answer these questions of interests.
About me: I love coffee, reading, Lego, stand-up comedy, Peanuts (comic), Japanese TV dramas, and Arsenal football club.
Samuel Goldstein
E-mail: sgoldstein41@gatech.edu
Research Interests: I am interested in understanding abnormalities in functional organization and neural circuitry in psychiatric disorders and how fMRI + TMS Neurofeedback can modify neural circuitry.
About me: I like to freestyle dance, design fashion, whitewater kayak, and go on spontaneous adventures!
Nadia Haddara
E-mail: nadiahaddara@gatech.edu
Research Interests: I am interested in the neural mechanisms underlying emotion-cognition interactions, specifically the influence of fear and threat-predictive environmental cues on how we perceive, attend to, and learn about meaningful associations. My current projects use functional neuroimaging (fMRI) to examine the impact of threat-related information on perceptual decision-making in the brain using a Pavlovian conditioning paradigm. I also have an interest in factors that modulate people’s basic visual perception and metacognition (i.e. the ability to reflect on and evaluate one’s behavior).
About me: I am an avid horseback rider who also enjoys running, reading any neuroscience book or fantasy trilogy I can get my hands on, and playing board games or just spending time with family and friends.
Kai Xue
E-mail: kxue33@gatech.edu
Research Interests: I am interested in how visual system is able to perceive information and make decisions. I want to integrate computational modeling, neuroimaging techniques, and behavioral experimentation to understand how visual system understands and reasons actions.
About me: I play the piano and the flute. For sports, I play table tennis.
