The Team

Walter Scheirer Very Small


Walter Scheirer (

Walter Scheirer is the Dennis O. Doughty Associate Professor in the Department of Computer Science and Engineering at the University of Notre Dame. His research is currently concentrated in several socially relevant areas, including artificial intelligence, media forensics, and information security. As an interdisciplinary scholar, his work is not exclusively technical, and takes a serious and critical look at the human element of various technologies within these spaces. He has published over one hundred technical articles and two scholarly books, and periodically writes for a public audience in the Bulletin of the Atomic Scientists. As a teacher, he emphasizes thought beyond the classroom, bringing students and technologists together in dialogue.

Graduate Teaching Assistant

Abby Swenor (

I am a first-year PhD student in computer science interested in NLP, digital humanities, and how computer science can play a larger role in interdisciplinary fields. I grew up in Pennsylvania, but spent a lot of time in Michigan, where my family is from, as a kid. I got my Bachelor’s degree in Computer Science at The University of Colorado - Colorado Springs where I did research in mitigating adversarial attacks on NLP deep learning models before starting my graduate work here at Notre Dame. I like to read and cook in my free time, and I look forward to attending ND football games this fall!

Ian Havenaar (

Hey everyone, my name is Ian Havenaar, and I'm a senior Computer Science major living in Siegfried Hall. I also have a minor in Engineering Corporate Practice. On campus, I am involved in undergraduate research through the Center for Research Computing and volunteer with CS for Good. In my spare time, I spend way too much time watching Chicago sports and, of course, the Irish. I am thrilled to be a TA for Ethics and Professional Issues this semester. Please reach out with any questions or concerns or comments. Thank you and Go Irish.

Coleen Valencia (

Hi! My name is CJ and I am pursuing degrees in Computational Math and Computer Science. I enjoy playing games (not League) with my friends whenever I get the chance. I am chronically online and excited to be a TA this semester after Professor Scheirer roasted me for being one of the two people last year who were on their phones more than six hours a day. Feel free to contact me regarding any questions you might have :)
