Graduate Students & Postdoctoral Scholars

Carolyn LaschCarolyn Lasch 

Carolyn is a National Science Foundation Graduate Research Fellow and third year graduate student in the DPCS program at UMN. She is interested in the role of caregivers and family in the development of social attention and cognition, especially in families at risk for anxiety and living in high-adversity contexts. 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.

ZeynepZeynep Basgoze

Zeynep is a postdoctoral associate, working under the supervision of Dr. Kathryn Cullen & Dr. Bonnie Klimes-Dougan in the Psychiatry and Behavioral Sciences Department at the University of Minnesota Medical School. She received her BA degree from the Philosophy Department at the Boğaziçi University, Istanbul, Turkey. She completed her MSc and PhD in the Cognitive Sciences Department at the Middle East Technical University, Ankara, Turkey. She worked as a postdoctoral fellow under the supervision of Dr. Emily Cooper in the Psychological and Brain Sciences Department at Dartmouth College, NH, USA and in the Optometry School at the University of California, Berkeley, CA, USA. Dr. Başgöze’s research focuses on the changes in the emotional and attentional mechanisms in the brain related to Major Depression Disorder, brain plasticity, visual adaptation, and binocular vision. She is specialized in designing and analyzing both fMRI and psychophysical experiments.

WiglesworthAndrea Wiglesworth

Andrea is a graduate student in the Clinical Science and Psychopathology Research Doctoral Program. She is interested in the relationship between forms of stress (e.g. minority stress in Native American populations, chronic stressors such as poverty, and childhood maltreatment) and suicidal thoughts and behaviors in childhood and adolescence. She examines neurobiological and psychophysiological mechanisms that may be related to these constructs. 

ConnerConner Falke

I am a graduate student in the UMN School of Public Health Biostatistics Division. I received my BA in Mathematics from the University of Kansas in 2019. I joined the RAD Lab because of my interest in finding both indicators and treatments for mood and anxiety disorders in adolescents. My work currently focuses on identifying clinically significant patterns of brain activity using fMRI data. I am also interested in developing new statistical methods that address the challenges of collecting and analyzing psychiatric data.

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.

Nathan began working in the RAD Lab as a research coordinator in September of 2016, focusing on two biological studies: Mitochondrial Dysfunction, Inflammation and White Matter Integrity in Youth with Mood Disorders and High-Field Imaging in Adolescents with MDD.  Nathan's primary research interests lie in the biological mechanisms of mental health, especially the convergence of the immune, endocrine and nervous systems. Previous to working in the amazing RAD Lab, Nathan practiced as a Naturopathic Doctor in Minnesota and Oregon and hopes to also explore research in integrative medicine in the future. His daughter loves rainbows, unicorns, her cousins and treats.  


Poojah SilamongkolPoojah Silamongkol

Hi! I am the study coordinator for the N-acetylcysteine Study. Prior to joining the RAD lab, I conducted research on child development and maltreatment as a senior research assistant at Child Trends. I have also worked closely with adolescents with high suicidal tendencies and self-harming behaviors while working in a DBT-focused residential treatment center. I am passionate about research on the neurobiology of depression, suicide, self-harm, and attachment in adolescents. 

Nikita TaveresNikita Tavares

Hello! I am the study coordinator for the Mindful Breathing and Transcranial Direct Current Stimulation (tDCS) Study for adolescents with depression. I graduated from the U of M in Spring 2019 with a degree in Child Psychology. My goal is to complete a master’s program to be a Licensed Professional Clinical Counselor. I am interested in working with teens and young adults. 

Undergraduate Students

EmersynEmersyn Goetz

Hello! I am a senior at the U majoring in Psychology with a strong interest in mental health and holistic well-being. I joined the RAD Lab to learn more about research and clinical psychology, especially the process of working with patients. I appreciate the lack of judgement and stigma among members of the RAD Lab, as well as feeling like a valued part of the team.

SalahSalah Mirza

Hi!  I’m Salah and I am a sophomore at the U studying Developmental Psychology in the Institute of Child Development.  My big interests are in developmental psychopathology, resilience science, and the mind-brain-body connection, especially in the context of family risk and intergenerational transmission of mood disorders.  I believe that the best interventions for children and adolescents are based on scientific research, so I’m really excited to participate in discovery which has the potential to directly improve the circumstances of youth experiencing or at risk for behavioral and/or emotional disturbances.  I plan on going into medicine in a specialty where I can continue to study and guide the development of children and adolescents.

HannahHannah Wehrman

Hi, my name is Hannah and I am a junior majoring in Psychology with a minor in neuroscience here at the U. I originally became interested in RAD Lab due to my interests in wanting to understand more about anxiety and depression and their underlying brain mechanisms. I have become further interested in self harm and suicidal behaviors.The lab has a great atmosphere and everyone is friendly and I enjoy the time I spend in the lab. My future plans are to go on to graduate school and hopefully the lab will help me find what it is I want to do with my degree. 

Matthew HildebrandMatthew Hildebrand

Hi, my name is Matthew and I am a sophomore majoring in neuroscience here at the U. I joined RAD Lab due to my profound interest in the neurobiological processes associated with depression in youth and adolescents. Additionally, I am interested in the impact early-life trauma has on the development of psychiatric disorders. After my undergraduate degree, my goal is to earn a Ph.D. and work in a clinical setting with children and adolescents. 

Dawson Hill's Photo Dawson Hill

Hi my name is Dawson Hill and I’m a junior studying Psychology here at the U. I became interested in the RAD Lab initially because of the research related to MRI imaging and how we look for indicators and signs of disorders based on brain structure. Additionally, I like being a part of the RAD Lab because of the team atmosphere involved and how everything comes together with many different contributions. As of right now, my goal is to become an adolescent psychiatrist working in a residential mental health treatment facility.

My name is Shalini and I am a freshman majoring in Neuroscience on the Pre-Medicine track. I joined the RAD Lab so that I could be immersed in research and see what it truly entails. As someone who has always been interested in psychology and how the brain functions the way it does, the RAD Lab has allowed me to gain a greater understanding of research as a whole and realize what areas I am most interested in. I am planning on attending medical school once I graduate from the U. 


Tori PapkeTori Papke

I am currently a junior at the University of Minnesota pursuing a B.S. in psychology and a minor in neuroscience. Since joining the RAD Lab, I have become particularly interested in treatment interventions for depression, and am thrilled to be part of the lab’s research helping adolescents who are struggling with depression and other disorders. My favorite quality of the RAD Lab is the teamwork and trust among the members, which gives undergraduate students the ability to be truly immersed in the research world and learn what it is like in great depth.
