Olivia Losiewicz |
|
|
|
Olivia is interested in using intra-individual and temporal data (such as ecological momentary assessment) to better understand the mechanisms underlying anxiety and related disorders and treatment. She is also interested in how social interactions impact anxiety symptoms. |

Brett Davis |
|
|
|
Brett wants to develop more precise, adaptive, and valid measures of symptoms relevant to depression and anxiety disorders. He, in turn, is interested in how these measures can help to select and personalize treatments to better serve individual needs. |

Kristen Chu |
|
 |
Kristen is interested in examining how early experiences contribute to emotion regulation and processing across the lifespan, and how they can alter subsequent risk for depression and anxiety. She hopes to study mechanisms that underlie risk for and development of anxiety and depression as well as the translation of this work towards neuroscience-informed interventions addressing these disorders. |

Kaylee Null |
|
 |
Kaylee is interested in individual differences in the neural, cognitive, and affective mechanisms underlying internalizing disorders. She is further interested in the impact of stress on emotion regulation and reward processing in depression and anxiety. She hopes such work may be used to inform novel, personalized treatment approaches. |

Yuhan Cheng |
|
 |
Yuhan aspires to contribute to the studies of internalizing psychopathology, in particular anxiety and depressive disorders, and its treatment. He is specifically passionate about experimental research that provides translational models (e.g., fear conditioning and extinction) for understanding the fundamental features of emotional disorders and optimizing mechanistically-focused interventions. Adopting a multi-method approach, Yuhan aims to pursue his lines of scientific inquiry by assessing processes underlying both psychiatric health and disease across the self-report, behavioral, physiological, and neurobiological levels of analysis. |

Brooke Cullen |
|
 |
Brooke is interested in a) broadening our understanding of how reward functioning mechanistically contributes to depression and anxiety and b) leveraging this knowledge to develop and improve interventions. She is particularly interested in how individuals with depression reflexively respond to and devaluate positive stimuli and mod states and how this cognitive tendency may hinder engagement with reward-focused interventions |

Yannie Darin Lee |
|
 |
Yannie is interested in exploring the transdiagnostic role of reward processes and approach-avoidance conflict in anxiety and depression. She is also interested in how positive affect can buffer against stress and promote well-being. Ultimately, she hopes her work may help inform the development of novel, evidence-based interventions to optimize outcomes across the lifespan. |

Purnima Qamar |
|
 |
Purnima is interested in exploring how early-life adversity influences 1) neurobiological mechanisms involved in the development of anxiety among diverse youth and emerging adults, 2) individual differences in subjective and neurobiological responses to threat, and 3) how structural and functional aspects of the brain are shaped by treatment. |
