Gray Matters Fellowship
Gray Matters at Columbia
Gray Matters at Columbia is a research fellowship fund within Columbia University Medical Center's Department of Psychiatry that provides support for outstanding scientists dedicated to searching for the causes and cures of brain disorders. I received the award for my work using fMRI to examine the neural underpinnings of emotion processing in individuals with autism spectrum disorders
Differences in neural activity when processing emotional arousal and valence in autism spectrum disorders.

Individuals with autism spectrum disorders (ASD) often have difficulty recognizing and interpreting facial expressions of emotion, which may impair their ability to navigate and communicate successfully in their social, interpersonal environments. Characterizing specific differences between individuals with ASD and their typically developing (TD) counterparts in the neural activity subserving their experience of emotional faces may provide distinct targets for ASD interventions. Thus we used functional magnetic resonance imaging (fMRI) and a parametric experimental design to identify brain regions in which neural activity correlated with ratings of arousal and valence for a broad range of emotional faces. Participants (51 ASD, 84 TD) were group-matched by age, sex, IQ, race, and socioeconomic status. Using task-related change in blood-oxygen-level-dependent (BOLD) fMRI signal as a measure, and covarying for age, sex, FSIQ, and ADOS scores, we detected significant differences across diagnostic groups in the neural activity subserving the dimension of arousal but not valence. BOLD-signal in TD participants correlated inversely with ratings of arousal in regions associated primarily with attentional functions, whereas BOLD-signal in ASD participants correlated positively with arousal ratings in regions commonly associated with impulse control and default-mode activity. Only minor differences were detected between groups in the BOLD signal correlates of valence ratings. Our findings provide unique insight into the emotional experiences of individuals with ASD. Although behavioral responses to face-stimuli were comparable across diagnostic groups, the corresponding neural activity for our ASD and TD groups differed dramatically. The near absence of group differences for valence correlates and the presence of strong group differences for arousal correlates suggest that individuals with ASD are not atypical in all aspects of emotion-processing. Studying these similarities and differences may help us to understand the origins of divergent interpersonal emotional experience in persons with ASD.
Using the circumplex model of affect to study valence and arousal ratings of emotional faces by children and adults with autism spectrum disorders.

The affective circumplex model holds that emotions can be described as linear combinations of two underlying, independent neurophysiological systems (arousal, valence). Given research suggesting individuals with autism spectrum disorders (ASD) have difficulty processing emotions, we used the circumplex model to compare how individuals with ASD and typically-developing (TD) individuals respond to facial emotions. Participants (51 ASD, 80 TD) rated facial expressions along arousal and valence dimensions; we fitted closed, smooth, 2-dimensional curves to their ratings to examine overall circumplex contours. We modeled individual and group influences on parameters describing curve contours to identify differences in dimensional effects across groups. Significant main effects of diagnosis indicated the ASD-group’s ratings were constricted for the entire circumplex, suggesting range constriction across all emotions. Findings did not change when covarying for overall intelligence.

This is actually the third time I invited Angela as my supervisor, and every time I was impressed by her kindness, professionality, and responsibility for the document. I especially liked the comments she gave on my drafts of SOP for PhD application this time, from which I can feel she was really putting herself into the admission committee's shoes when digging valuable details from my questionnaire and CV and sorting out the logic of the write-up. Besides, she gave sufficient edits to every version of the manuscript. I could say the finalised essay has elaborated every critical point and has successfully conveyed my passion in the research topic such that it has played an important role in impressing my targeted PhD supervisor. I strongly recommend Angela as your supervisor!
FYI I've got the offer from my dream institute with the help of Angela!’

She is really nice, patient and even willing to help me modify my SOP at Christmas vacation! She asked my CV for a complete insight into my past research experience and incorporated a lot of details which makes my SOP far more attractive!
