Undergraduate Students

ClaraClara Bils


My name is Clara and I use they/them pronouns. I currently volunteer as a study coordinator for our Sexual Minority study and I work as a mental health technician at a group home for adults with severe and persistent mental illness. I am interested in psychopathology prevalence, identity formation, and stress response within the LGBTQ+ community. I hope to pursue a PsyD in clinical psychology and eventually work in an acute mental health illness facility.

ZayZay Hayee

My name is Zay (she/her) and I am a second year Psychology major with a minor in Spanish at the U. I plan to pursue a PsyD and work clinically with adolescents and young adults. Disorders and treatments related to this age group are of particular interest to me along with the mental health effects that may be associated with identifying as a first/second/third generation American. I am also passionate about raising awareness of mental health disorders and treatment within the Southasian community because it is an often neglected discussion. The RAD lab is a great opportunity to launch my research journey and start exploring these interests in greater depth.

SalahSalah 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.

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.
