My name is Ira Globus-Harris, and I am a fifth year PhD student in the computer and information sciences department at the University of Pennsylvania, co-advised by Aaron Roth and Michael Kearns. My work, which is grounded in the algorithmic foundations of responsible computing, broadly looks at mechanisms to resolve potential harms incurred by AI-driven decision-making. In particular, my work focuses on using algorithmic techniques which are scalable for real-world use, holistically consider an algorithm in its broader context, and which flexibly incorporate human input. I am particularly interested in methods which provide flexibility to adjust models after deployment in scalable and efficient ways.
Prior to Penn, I worked at Boston University as a software engineer with SAIL and with the Harvard Privacy Tools Project. I got my bachelors degree from Reed College in Portland, OR.

I was the president of the Penn school of engineering and applied sciences' group for LGBTQ+ graduate students from 2020-22, and am a diversity council representative for the school of engineering and applied sciences. While at Penn, I have led and advocated for several changes for trans inclusion within the school and the university more broadly. While in undergrad, I co-led the group for gender minorities in STEM fields. I also designed curriculum and taught a computer science outreach program to a local elementary school while at Reed, and painted some fun murals which have now inspired some other fun murals.
