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

Louisa Conwill (

I am a first-year PhD student in computer science interested in ethical problems in technology and how Catholic Social Teaching can inform our response to these issues. I’m from Oregon (but also spent a lot of my childhood in Japan), got my Bachelor’s in computer science at Brown University, worked as a software engineer for Amazon Alexa in Boston for two years, and then served as a campus missionary with the Fellowship of Catholic University Students (FOCUS) at Carnegie Mellon for two years before coming to Notre Dame. In my free time I enjoy running and playing the ukulele (mediocrely), and I’m the most lactose tolerant person you’ll ever meet.

Undergraduate Teaching Assistant

Zachary Kreft (

Hi, my name is Zach Kreft, and I'm a senior computer engineering major. I'm excited to use my degree to work for Vertiv, a company that specializes in data center devices, post-graduation. Aside from engineering, I run cross country and track for the university. I'm from the great state of Ohio and live just north of Columbus. Nothing beats the buckeye state, but I may be a little biased... I took this course last semester with Professor Scheirer, and I'm looking forward to helping you all where I can! 

Office Hours: By appointment.

Undergraduate Teaching Assistant

Nicholas Zullo (

Hi, I'm Nick Zullo, a transfer senior, CPEG major at Notre Dame! I studied Computer Science at Stonehill College in Easton, MA for three years to receive a B.A. in that (weird right?). I also played football over there at the D2 level and now Semi-Pro back home for the Mill City Eagles out of Lowell, MA (I wouldn't dare try here!). I am finishing up my second year here at ND and am super excited to spend the semester helping you all!

Zakiya George

Undergraduate Teaching Assistant

Zakiya George (

Hi, my is Zakiya George, and I’m a senior studying Computer Science. I’m from Atlanta, Georgia and my family is originally from Guyana, South America (which is where you’ll likely find during any given holiday break). When I’m not studying computer science, I enjoy working out in Duncan and swimming at the Rock. In addition to Computer Science, I have a particular interest in finance and will be pursuing a career in the financial services industry post-grad. I took this course with Professor Scheirer last semester and was immensely interested in the ethical problems in technology we covered. I’m looking forward to helping you guys wherever I can as you go through a similar journey this semester!
