Graduate Students & Postdoctoral Scholars

Carolyn Lasch 

Carolyn Lasch

Carolyn (she/her/hers) is a Doctoral Dissertation fellow and graduate student in the Developmental Psychopathology and Clinical Science program at UMN. She is interested in the role of caregivers in the development of social attention and cognition, especially in families at risk for anxiety and living in high-adversity contexts. Her work also focused on how early anxiety is reflected in brain development, and how this may vary in different diagnostic groups (e.g., children with ASD). Prior to graduate school, she worked at UMN as a project coordinator primarily focused on neuroimaging, behavioral, and eye-tracking assessments. She received her B.A. in Psychology from Scripps College in 2015 and her M.A. in Child Development from UMN in 2019.

I am currently a graduate student in the Clinical Science and Psychopathology Research Program program. My interests focus on understanding the cognitive and neural mechanisms underlying mood and anxiety disorders. I am particularly interested in the use of neuromodulation as a tool to study and treat affective disorders.





Tori Papke


Tori (she/hers) a graduate student in the Clinical Science and Psychopathology Research Doctoral Program. She started in the lab as an undergraduate volunteer in 2019 and has since graduated from the University of Minnesota with a B.S. in 2021 and worked as a project coordinator for the NAC Study. She is particularly interested in studying stress in relation to development and psychopathological outcomes, such as suicidality and self-harm. 

Kate Carosella


Kate (she/her/hers) is a graduate student in the Clinical Science and Psychopathology Research Doctoral Program. She graduated with a Bachelors of Science from Johns Hopkins University. She is interested in understanding the neural basis of maladaptive responses to stress such as self-injury and suicide. She hopes to elucidate how evolutionarily adaptive processes such as threat processing can go awry on the system neuroscience level and result in psychopathology. She loves baking, swimming, and cuddling her dog, Mozzarella!

I am a PhD student in clinical and developmental psychology at the Institute for Child Development, after spending my BA and masters degree focusing on post-violence literature and collective resilience practices. In the long term, I hope to partner with communities of diverse cultural backgrounds to design more effective and culturally appropriate trauma treatments that rely on locally effective resilience mechanisms. In addition to conducting assessments in the RAD Lab, I am fortunate to receive mentorship from Dr. Gail Ferguson and Dr. Ann Masten.

Undergraduate Students

Zay Hayee


"I'm Zay (she/her), a third year undergrad in the Psychology program with a minor in Spanish. My main interest areas in Psychology are adolescent/developmental, mood and anxiety disorders (from a clinical and research perspective), and research procedures and ethics. I'm also interested in raising awareness about mental health conditions and struggles within the SouthAsian community. Down the line, I would like to go to grad school and work in research and academia. Outside of school, work, and lab, I enjoy reading, cooking, watching TV shows, and hiking.

Salah Mirza

Salah Mirza

Hi, I’m Salahudeen (Salah) Mirza, and I’m an undergraduate studying child development with a minor in cellular and molecular neuroscience.  My interest has been in understanding the developmental pathways to suicide and other self-injurious thoughts and behaviours.  This interest has spanned multiple levels of analysis including imaging of the brain’s structure and function, salivary cortisol assay, gene expression in animal models of mood disorder, and genetic and epigenetic variation in studies of post mortem brain tissue of suicide decedents.  I am especially interested in improving our ability to predict youth suicide attempt/death risk using multiple methods.  Another interest of mine is the transmission of suicidal behaviour and affective disorder across generations.  Within the lab, the main datasets I have worked with are BRIDGES and ABCD (NIH), both of which are longitudinal cohorts.  My hope is that some of the pathways and risk/protective factors that we identify prove helpful in identifying those at high risk for suicide, with the possibility of aiding in targeted interventions.  I’m really grateful to be working as part of such a caring and supportive team.

Jordan Frederiksen

In RAD lab, my current activities involve primarily data entry, organization, and triers. My data entry primarily involved physical into digital versions of the data collected over the years. Over the spring and early summer semester, I helped a grad student with her systematic review of early life stress. I'm interested in personality disorders as I feel as it's a neglected and stigmatized area in psychology/psychiatry. In my Intro to Abnormal Psychology class with Dr. Klimes-Dougan, the textbook Abnormal Psychology by Hooley, Nock & Butcher stated that many with borderline personality disorder are rejected by therapists and clinical psychologists due to their nature. This shouldn't be the case. Long-term, I intend to start with an MD and work towards a specialty in psychiatry. These plans may change as I want to do a mixture of clinical psychology and psychiatry, as I want to blend the fields in terms of their treatments.




Aly Hayashi


Hi, my name is Aly and I am a junior majoring in Neuroscience and Japanese on the pre-med track. I am very interested in anxiety and depression and want to learn more about their neurobiological processes. In addition, I'm interested in learning how to predict and use preventative measures in young children to lessen the probability of depression and anxiety. I intend on pursuing medical school and possibly an MD/PhD.

Hi! I'm Josie (she/her), a junior majoring in human physiology and psychology. I joined the RAD Lab due to my interest in improving mental health outcomes for adolescents. I look forward to learning more about neuroscience and its relation to anxiety and mood disorders. In the future, I hope to pursue a career that combines use of psychosocial skills with knowledge of health, illness, and healing. Outside of school and my work with the lab, I enjoy baking, thrifting, and trying new restaurants.

Hello, my name is Choolwe (he/him/his) and I’m a fourth year student studying psychology on a pre-med track. This will be my first semester working in the lab. As someone who is interested in being a psychiatrist one day, I couldn’t be more excited to further explore my interest in preventative strategies for adolescent depression through the work I’ll be doing in this lab. I also can’t wait for the RAD Lab to be an opportunity to dive deeper into the greater work done within research. In my free time, I enjoy spending time with friends and watching sports.

Hi, my name is Sam (he/him) and I'm a senior majoring in psychology with a minor in biology in the College of Liberal Arts. After taking Dr. Klimes-Dougan's abnormal psychology class as a junior and preparing for my research practicum, I joined the RAD Lab because of my interests in studying anxiety disorders in adolescents and the lab's focus on developmental psychology and role of brain structure and function in psychological disorders. In my time in the lab, I have become increasingly interested in studying the functions of non-suicidal self-injury in adolescents. My future plans involve graduate school in the health sciences.

Anya Pavlova

My name is Anya (she/her) and I am a volunteer in the lab, primarily working as the study coordinator for the Becoming Artists study. I am a junior majoring in biology and psychology, and I plan on going to medical school after college. I joined the RAD lab because I have an interest in improving mental health outcomes, and I am considering going into psychiatry in the future, so this is a great place to further explore neurobiological mechanisms in adolescents as well as treatment options for various mood disorders. Outside of school, I love to hike, cook and travel!

Olivia Costa


My name is Olivia (she/her) and I am a third year student majoring in Psychology and minoring in Neuroscience and Spanish. After graduation, I plan to pursue a PhD in Clinical Psychology, and my research interests center on identifying approaches to improve the mental health of adolescents with intersectional identities (e.g. LGBTQIA+ and Latine). As part of RADLab I worked on the Creativity Camp Study project, which was a great opportunity to learn how to run a research study and analyze data. The RADLab provided me with research experience relevant to my interests and fueled my curiosity in the study of human behavior.
