Luke Robinowitz (He/HIm/His)

My name is Luke Robinowitz, I am 29yrs old, and my preferred pronouns are He/Him/His. I am a second-year graduate student in the PhD program for Sociology currently finishing my master’s degree in the same field. In 2019, I graduated from Portland State University with a BA in Sociology; I loved the subject and this school/campus so much, I figured I may as well just keep it going until I’m finished. Beyond my work as a student, I am also a Graduate Teaching Assistant here at PSU and hope to gain valuable experience teaching coursework both online and in=person so that I may become a professor someday. I am originally from southern California but uprooted to Oregon when I was 7yrs old and lived in Estacada, OR until I graduated High School in 2008. I have lived, mostly, in the SE Portland area ever since.

Why am I pursuing a Master’s/PhD in Sociology?

I grew up the youngest of 4 children in a family whose parents were impoverished, under-educated, and suffered from drug addiction and undiagnosed mental illness. As someone who has experienced substance dependence, the criminal justice system, mental-illness, and the stigma that follows each -both personally and in witnessing each’s effects on my loved ones- I have made it my goal in life to help those who struggle with these (and similar) issues so that they never feel alone or abandoned traversing through the confusing and contradictory avenues of treatment, restitution, and remediation. I want to be a part of research that highlights and addresses the social/environmental conditions, the laws and public policies, and the stigma and perceptions inside our social stratosphere that are related to the onset of mental illness and substance dependency within certain populations.

My research focus, preferred methodology, and general interests?

I have always felt as if I’m probably best suited for quantitative methodology; numbers are uniform, predictable, and I used to love math (started college focused on Accounting.. yuck.. ) but what I love about qualitative methods is that it allows individuals who have been systematically marginalized and whose stories have been excluded from history and discourse to finally have a voice to share their experiences. Addiction and Mental Illness are still fairly new topics of discussion in society, and as such, there are, and have been, many models to use and mistakes to make in hopes of alleviating either their effects on the individual themself -or- arresting the effects of the individuals behavior on society. The crack epidemic was a personal, moral failing but the heroin epidemic was a medical mishap. I’m interested in understanding why this is and sharing my findings with those who share the same goals.  My theoretical framework that I frequently use can be summarized as a radical discourse analysis with focus on identity construction, negation, and contradictions. My most influential theorists in my work are Marx, Foucault, Goffman, and Butler. He can be reached at
