Isabella Kahhalé
Clinical & Developmental
Psychology
I'm a fourth-year Clinical-Developmental PhD student at the University of Pittsburgh studying early life adversity, neuroscience, antisociality, & prosociality.
I work with Professor Jamie Hanson to understand how adverse childhood experiences influence the development of a) the brain, b) antisocial behavior (e.g., aggression, criminality) and c) prosocial behavior (e.g., empathy, helping behaviors).
After graduating with a B.S. in Cognitive & Brain Sciences from Tufts University, I joined the Stanford Social Neuroscience Lab led by Professor Jamil Zaki to study the neural foundations of empathy.
I am also passionate about service work with under-resourced members of my community and incorporating a culturally-humble lens in my research and clinical work.

Check out some of the projects that I'm currently working on below! Stay tuned for updates on the work below and the other fun topics in the pipeline.
Structural Brain Connectivity, Childhood Maltreament, & Antisocial Behavior
My Master's Thesis probes the associations between structural brain connectivity, childhood maltreatment, and later antisocial behavior.
Many of the neural structures implicated in childhood maltreatment are crucial components of emotional regulatory brain networks, connected through pathways including the uncinate fasciculus, the cingulum bundle, and the fornix.
Poorer emotion regulation has been pointed to as an underlying factor contributing to antisocial behavior; therefore, we are exploring if alterations in neural emotion-regulatory pathways significantly account for a portion of the established link between childhood maltreatment and adult antisocial behavior.
Early Life Adversity & Empathy
Research has established childhood maltreatment as a powerful antecedent to an array of socioemotional problems, but it is less clear how experiences of early life adversity, such as childhood maltreatment, impact empathy. Empathy is a fundamental skill linked to social development and resilience and underpins critical processes such as successful interpersonal interactions, bond formation, and prosocial behavior.
I am currently investigating the associations between early life adversity and empathic accuracy in an online study.
Perspective Taking & Sentencing Outcomes
Empathy can influence our understanding of others and bias our decision making. While at the Stanford Social Neuroscience Lab, I investigated how taking the perspective of a victim or a perpetrator of a crime might impact the extent to which we punish and dehumanize the perpetrator.
We have conducted a) an exploratory experiment, b) a second replication study pre-registered on the Open Science Foundation, and c) an analysis of restricted-access archival data on over 12 million national incarceration records.
We found that hearing the perpetrator’s perspective led to a shorter recommended sentence, and more importantly, less dehumanization. These results highlight the impactful nature of someone’s story in influencing perceptions of their behavior. This work has been presented at two national conferences and is currently in preparation for submission.

Biography
I am a Lebanese-American from Boston, MA now in Pittsburgh for graduate school, seeking to understand how early adverse experiences shape developmental trajectories. My parents survived the Lebanese Civil War and worked tirelessly to provide a better life for my brother, my sister, and me; I have them to thank for instilling in me a) a curiosity to understand how trauma and adversity impact behavior and well-being, b) a passion for service work within my community, and c) an undying love of food.
I am a doting mother to two adopted cats, Momo (pictured left, named after Maury the hormone monster on the Netflix show Big Mouth) and Mimi (pictured right, named after the NPR host Lakshmi Signh). Ask me for more pictures and I promise the content will never stop.
Hobbies
Staying active is the main tool in my self-care arsenal. I "enjoy" (i.e., suffer through) crossfit workouts, rowing, snowboarding, cycling, and poorly playing tennis.
I also love reading (particularly audiobooks, and particularly ones read by the author), traveling during non-pandemic times, and eating. If you find yourself in Pittsburgh one of these days, please reach out for food recommendations; I'd get a lot more research done if I spent as much time reading papers as I do menu-prowling.
