About Me

I am a third-year PhD student in Computer Science working with Dr. Christo Wilson at Northeastern University's Cybersecurity and Privacy Institute. I am an organizer of the Khoury Women's PhD Group. My research focuses on consumer protection and AI ethics through a multidisciplinary approach. Depending on the project, this could range from qualitative coding to intercepting app traffic to analyzing network patterns.

Before Northeastern, I attended Smith College for undergrad, earning my BA in Quantitative Economics and Statistical and Data Science in 2022. I then worked at Sartorius Stedim Biotech in a Biosafety Level 2 laboratory as a metrology/quality engineer, including involvement in routine FDA audits.

I have two ongoing projects. One is *AI Social Robots*, which looks at safety analysis regarding consumer social robots' response content, self-harm, and privacy. The second is *Heterogeneity of Vehicle DSAR Responses*, which extends my prior network traffic vehicle analysis by also analyzing about 40 crowd-sourced DSAR responses from participant's vehicle companies. Once I get these two papers submitted, I aspire to look at medical devices privacy next.

I often have a volunteer (unpaid) spot in my projects for a smart, hardworking undergrad who wants research experience on the research topics I'm currently examining. Send an email if you're interested.
