Our Lab Members

Principal Investigator

A/Prof Susanne Schweizer


I am a Scientia Associate Professor and Australian Research Council DECRA fellow at the UNSW School of Psychology. My lab studies the role of cognitive, social and affective processes in the development and maintenance of common mental health problems across the lifespan, with a particular focus on adolescence and the perinatal period.  

We are interested in finding out how these processes all work together. Does cognitive capacity influence other processes such as emotion regulation? And how? What does this look like in the brain and how does it change as we get older or during certain reproductive periods?  

We also know that peers and social information, such as who likes us and who doesn't, becomes very important during adolescence. More important in fact than at any other time in our lives. In our lab we are exploring how individual differences in the sensitivity to this social information is related to young people's mental well-being and their cognition – even their ability to learn new things.  

Adopting a translational perspective, I apply insights from this work in basic developmental cognitive neuroscience to design novel interventions for mental health problems including depression, anxiety and posttraumatic stress disorder. Before establishing the Developmental Affective Science Lab, I was a Sir Henry Wellcome Fellow at the University of Cambridge and the UCL Institute of Cognitive Neuroscience and I worked as research fellow at the MRC Cognition and Brain Sciences Unit. I completed my PhD in Cognitive Neuroscience as Gates Scholar at the University of Cambridge.

Postdoctoral Research Associate

Dr Jodie Pestana


I am a behavioural neuroscientist researching women’s mental health. In particular, my research investigates how female-specific experiences, such as hormonal fluctuations during pregnancy and the menstrual cycle, influence the brain’s ability to regulate mental health and respond to treatments. Investigating this is important given that many mental health conditions, including anxiety and depression are twice as common in women compared to men, yet the vast majority of studies are conducted on the male brain only. I completed my PhD in behavioural neuroscience in 2023, and I am currently a postdoctoral researcher at the School of Psychology at UNSW working with A/Prof Susanne Schweizer and Prof Bronwyn Graham. I am a proud advocate for women’s mental health, delivering award-winning talks and eagerly sharing science with the public. I was recently selected to be a Superstar in STEM for 2025-26.  As a lifelong soccer player inspired by the Matilda’s at the World cup, I am dedicated to encourage more women and young girls to break barriers and increase female representation in STEM and beyond.

Postdoctoral Research Fellow

Dr Lucy Zhang


I am a Postdoctoral Research Fellow in the DAS Lab at the School of Psychology, UNSW, working with A/Prof Susanne Schweizer. My research focuses on resilience—how individuals adapt following significant challenges. Specifically, I am interested in resilience to the negative mental health effects of childhood adversity and trauma. During my PhD at the University of Melbourne with Prof. Sarah Whittle, I explored resilience in the context of adolescent mental health. In the future, I hope to continue this line of research while also expanding into resilience in women during the perinatal period, with a focus on the underlying mechanisms and contributing factors that foster resilience during this major life transition. Outside of research, I am a big cat and dog lover and a proud owner of three cats and a dog!

PhD Students

Weike Wang


I am a PhD student interested in how adolescents deal with uncertainty. My PhD investigates cognitive factors, especially the role of episodic memory, in adolescents' response to uncertainty and mental health outcomes. I completed a Bachelor of Science (Psychology) (Honours) at the Australian National University and my Honours project explored the effects of hope and fear on people’s attitudes towards positive unknowns. I have also worked as a research intern assisting the development of digital mental health products at Institute of Psychology, Chinese Academy of Sciences. In my spare time, I enjoy playing ultimate frisbee with friends. 

Anna Bilston


I am a joint PhD and Masters student at the DAS Lab. I completed my Bachelor of Psychology (Honours) in 2024, investigating factors impacting the relationship between adolescent’s online social interactions and their mental health. I am particularly interested in child and adolescent development, parenting and education. I am studying psychology to be able to help young people, especially those with mental health or neurodiverse conditions, and their families, successfully navigate the challenges of life. After a career in business advisory and marketing (which I loved because of the psychology behind decision making and consumer brand adoration), my interest in clinical psychology came from my experiences with one neurodiverse and one neurotypical son, who keep me on my toes 24/7. My boys are now great at long haul flights and eating most things as my partner and I have shared with them our passion for travelling as often as possible, and seeking new food experiences here, there and everywhere, and if I ever get a moment to myself, I love art and drawing.

Napat (Keen) Burapath


I am a PhD student studying how people respond to uncertainty, and how exposure to unpredictability, such as social uncertainty, during sensitive periods like childhood and adolescence might contribute to depression and anxiety. Through my project, I hope to contribute to a mechanistic understanding of uncertainty intolerance that can be used to develop novel and scalable interventions for mental health. I completed my undergraduate studies in Psychological and Behavioural Sciences at the University of Cambridge, where I was a Jardine Scholar. My project explored the causal relations between loneliness and depression in adolescents with Professor Sarah-Jayne Blakemore. I also spent time at the MRC Cognition and Brain Sciences Unit assisting research into factors contributing to the amnesic shadow. In my spare time, I enjoy playing music and sailing when the weather is nice.

Florencia Canessa Zamora


I am a PhD student exploring women’s wellbeing during the perinatal period, amazed by how women (and their babies) navigate all the biological, psychological and social changes that they undergo during and after pregnancy. I hope with my research I can contribute to providing a framework that captures maternal resilience and change during the peripartum period. Before joining the lab, I worked as a clinical psychologist in Chile, and a research assistant at Leiden University in the Netherlands, in the fields of mental health, developmental psychology and neuroscience. I completed my undergraduate psychology studies at Pontificia Universidad Católica de Chile, and I hold a master's degree in Applied Neuroscience in Human Development from Leiden University.

Masters Students

Nita-Roya Roschanzamir


Honours Students

Yasmin Hasan


I am a student research assistant in the lab, and am currently completing my Bachelor of Psychology (Hons) at UNSW. I am fascinated by research on the intersection of cognition, neuroscience and child/adolescent mental health as well as health psychology and the science of learning and memory. I am particularly interested in utilising scalable interventions to support youth mental health and wellbeing. In my free time I enjoy playing piano and reading.

Jasmine Chan


I am an Honours student in Psychology at the University of New South Wales. My current research explores the motivations behind online social interactions and how they influence mood and mental health in adolescents. I am particularly interested in the development of mental health disorders across the lifespan, with a focus on key developmental stages such as early childhood and adolescence. My areas of interest include attachment and trauma and their contributions to mood, anxiety, trauma/stressor-related, dissociative, and personality disorders. In the future, I aspire to work in clinical or school settings, providing treatment for neurodivergent children and adolescents. In my free time, I enjoy spending time outdoors with friends.

Yan Lin


I am an Honours student in Psychology at the University of New South Wales, currently working on the Perinatal Pilot Study. My research investigates how mothers experience unwanted intrusive thoughts of infant-related harm, with a particular focus on how cognitive appraisal of these thoughts influences their persistence, associated distress, and broader maternal wellbeing. My earlier education was in International Finance, and I hold an MBA as well as a Graduate Diploma in Psychology. I have extensive professional experience in venture capital and startups. My interest in psychology grew both from my time in the business world and from my personal experience raising three children. I feel fortunate that, approaching the age of 50, I have the opportunity to study science and explore the human mind and behaviour in depth. In my spare time, I enjoy tennis, fitness training, and spending time with my family.

Research Assistants

Sarah Daniels


I am a research assistant here in the DAS Lab, and have recently completed my Bachelor of Psychology (Honours) degree in 2023. My honours thesis, supervised by A/Prof Schweizer, investigated the efficacy of our novel online intervention in improving the mental health of young people via increasing tolerance of uncertainty. I have previous research experience with the Black Dog Institute and the Refugee Trauma and Recovery Program. I am also passionate about clinical, health, and cross-cultural psychology, and have specific interests in adolescent psycho-oncology and transdiagnostic processes. Apart from this, I love to travel and spend time with friends.

Emily Morgan


I am a research assistant in the DAS Lab, working primarily on the Wellcome-funded perinatal mental health project. I am currently in my third year studying a Bachelor of Arts at the University of Sydney, with a double major in Philosophy and Psychology. In 2024 I was awarded the Denison Research Scholarship to undertake a literature review on conceptual and methodological issues in quality of life research. I also have experience conducting thematic analyses to inform strategic directions for the NSW Department of Education. I am particularly passionate about the intersection between the humanities and science, and using insights from philosophy to bring greater conceptual depth to psychological research.

Martín Miranda


I am a psychologist and data scientist, working as research assistant at the DAS Lab. I am currently analysing data for multiple projects, where I explore emotional regulation and the development of social networks across the lifespan. I am interested in how novel methods in computer science can help us in understanding people. In the future, I want to use computer vision methods to portray human behaviour in a meaningful and comprehensive way. 

Before joining the lab, I was a Research Master Intern at the BODIES Research Group in the Department of Biomechanical Engineering at Delft University of Technology in the Netherlands. I also collaborated with the Centre for Advanced Research in Education and the Centre for Early Childhood Studies in Chile, conducting research on educational policies. I hold a Master's degree in Statistics and Data Science from Leiden University and a Bachelor's degree in Psychology from the Pontificia Universidad Católica de Chile.
