The Department of Computer Science is dedicated to advancing and improving the knowledge, understanding, and practice of computer science through basic research and education.

## Research

We have a broad view of Computer Science, that includes the whole spectrum of computing, from relevant mathematics and statistics to building hardware devices, networks, data science, machine learning, human computer interaction, and Computer Science education. The list is not exhaustive, but an attempt to convey some of the research interests of current faculty. We investigate computation, information, communication and data as fundamental phenomena to be studied in Computer Science. We also investigate the many interdisciplinary ways the study of computation interacts with other disciplines like the sciences, society, and learning.

There is an ongoing major thrust to expand the role of Computer Science and computation at the University, with considerable expansion of the faculty, and expanded support to explore new research areas. These include the new Center for Data Science, a joint effort of the Statistics and Computer Science Departments, that is also experiencing rapid growth. Accordingly, the descriptions below, a snapshot of our current active research, are likely to expand.

Current active research areas include computing systems, computer architecture, computer security and privacy, error-tolerant computing and error recovery in computing systems, databases and data intensive computing, theoretical computer science, discrete mathematics, quantum computing, programming languages, machine learning, computational linguistics, computer vision, cloud computing, sustainable computing, scientific computing and visualization, high performance computing, human-computer interaction, computer science education, and interdisciplinary research in computing in the physical, biological, and social sciences.

Current major research areas include:

Theoretical Computer Science

Programming Languages

Data Science

Machine Learning and AI

HCI

Scientific and High Performance Computing

Computer Science Education

For more information about current research groups and active research areas, refer to the Research section of the departmental webpage.

Our research efforts are enhanced by the interdisciplinary nature of the University, and, specifically, by strong connections to the Center for Data and Computing (CDAC), the Center for Translational Data Science, the James Frank Institute, the Institute for Biophysical Dynamics, with the Pritzker School of Molecular Engineering, and with the Booth School of Business. Our research collaborations involve faculty from many different departments, including Mathematics, Statistics, Physics, Linguistics, Psychology, and Sociology. We have very strong research ties with ANL, the Argonne National Laboratory, operated by the University for the US DOE. We also have almost seamless collaborations with the Toyota Technological Institute Chicago, on campus: many TTIC faculty have part-time appointments in the Department.

## Graduate Programs

We offer two graduate curricula in computer science.

- A graduate professional curriculum leading to the Master of Science (MS) degree, for students who wish to enter or advance themselves in computer science practice.
- A graduate research curriculum leading to the PhD degree that prepares students to perform advanced basic research in computer science either in industry or academia. Teaching experience is available for students preparing for academic careers.

General information about our department is available from the departmental website.

## The PhD Program

The PhD program is done in three phases:

### Qualifying Phase

The objective of the Qualifying Phase is to provide the scientific foundations in their area, a breadth of knowledge within Computer Science, and the ability to write up research results. Students without a previous MS should satisfy course requirements, and write and defend an MS paper.

The course requirement consists of five core courses (two in Theory, two in Systems, and one in ML), three electives, and a seminar. In order to ensure breadth, no more than four of these courses should be in the student's main research area.

After the public defense of the paper, the student may be eligible to receive an MS in Computer Science from the University. Please refer to the departmental webpage for details.

Students with a previous MS may receive credit for their previous work: up to waiving the core course requirement. The details of the mechanism to do so can be found on our website.

The minimum formal requirements for the core courses (”Ph.D. Pass”) are the following: Students are required to complete the five core courses with a grade point average (GPA) of at least 3.25 in the five core courses. In computing the GPA, A=4, B=3, and a + or a - counts as .3 of a point. Note that for the core courses, students who significantly outperform even the typical ”A” students may receive a grade of ”A+” (recorded internally by the CS Department Student Representative since the University does not officially grant the grade of A+.) So, for instance a student with grades A+, B+, B+, B-, B- in the five core courses has a GPA of 3.26 and thus satisfies the minimum GPA requirement, as does a student with grades of A+, A, B+, B, and C-. In the graduate program grades below C- are not passing grades.

Students must complete their electives with a grade of B or better in each course.

### Candidacy Exam

After the Qualifying Phase, students must pass an exam for Admission to Candidacy, that is a plan for their dissertation research.

### Dissertation and Dissertation Defense

Finally, they must write and defend their dissertation.

## Teaching Opportunities for Students in the PhD Program

The department takes its undergraduate teaching responsibilities very seriously, and offers supervised teaching opportunities, including lecturing, acting as teaching assistants, and working as lab assistants to its best graduate students.

## Computing Facilities

In addition to the general University computing facilities including the Research Computing Center (https://rcc.uchicago.edu/resources) and access to high performance computers at ANL, and our Computer Science Instructional Laboratory (which contains about 50 Macintosh computers and 40 desktops running Linux), our department provides the faculty, students, and postdoctoral associates in computer science with computing resources. We have the flexibility to adapt quickly to new research needs.

The resources include: 24 hour 7 day interactive computing on a number of shared computing servers as well as individually assigned desktops. These servers and desktops run the Linux operating system and are interconnected via high speed Ethernet. These systems are supported by substantial amounts of both local and networked disk storage for individual group use and are backed up regularly. Linux servers are available for general instructional and research purposes as well as hardware and virtual machines which are adapted to specialized needs.

Individual research groups operate additional computing facilities, often with considerable computing and storage resources. Some have specialized hardware, and fabrication tools (for example, GPU arrays, 3-D printers, etc.). Information about these resources is available from the research group's webpage.

## Joint Math/CS PhD program

The Department of Computer Science and the Department of Mathematics offer a joint PhD program. For more details see https://mathematics.uchicago.edu/graduate/joint-math-cs-phd-program/

**CMSC 30370. Inclusive Technology: Designing for Underserved and Marginalized Populations. 100 Units.**

Creating technologies that are inclusive of people in marginalized communities involves more than having technically sophisticated algorithms, systems, and infrastructure. It involves deeply understanding various community needs and using this understanding coupled with our knowledge of how people think and behave to design user-facing interfaces that can enhance and augment human capabilities. When dealing with under-served and marginalized communities, achieving these goals requires us to think through how different constraints such as costs, access to resources, and various cognitive and physical capabilities shape what socio-technical systems can best address a particular issue. This course leverages human-computer interaction and the tools, techniques, and principles that guide research on people to introduce you to the concepts of inclusive technology design. You will learn about different underserved and marginalized communities such as children, the elderly, those needing assistive technology, and users in developing countries, and their particular needs. In addition, you will learn how to be mindful of working with populations that can easily be exploited and how to think creatively of inclusive technology solutions. You will also put your skills into practice in a semester long group project involving the creation of an interactive system for one of the user populations we study.

**CMSC 33218. Surveillance Aesthetics: Provocations About Privacy and Security in the Digital Age. 100 Units.**

In the modern world, individuals' activities are tracked, surveilled, and computationally modeled to both beneficial and problematic ends. Jointly with the School of the Art Institute of Chicago (SAIC), this course will examine privacy and security issues at the intersection of the physical and digital worlds. Through both computer science and studio art, students will design algorithms, implement systems, and create interactive artworks that communicate, provoke, and reframe pervasive issues in modern privacy and security. The course will unpack and re-entangle computational connections and data-driven interactions between people, built space, sensors, structures, devices, and data. Synthesizing technology and aesthetics, we will communicate our findings to the broader public not only through academic avenues, but also via public art and media. The first phase of the course will involve prompts in which students design and program small-scale artworks in various contexts, including (1) data collected from web browsing; (2) mobility data; (3) data collected about consumers by major companies; and (4) raw sensor data. Students will receive detailed feedback on their work from computer scientists, artists, and curators at the Museum of Science & Industry (MSI). The course culminates in the production and presentation of a capstone interactive artwork by teams of computer scientists and artists; successful products may be considered for prototyping at the MSI.

**CMSC 33580. The Value of Data. 100 Units.**

While data and artificial intelligence are driving many changes to our economic, social, political, financial, and legal systems, we know little about their foundations and governing dynamics. While the recombination and integration of diverse data creates vast new value, we currently have neither theory for how data can be combined nor an industrial policy for how to protect against the personal exposures and abuses that grow in proportion. Many of these issues call for treating data as a first-class citizen and thinking of it as an asset. What is the value of data, and how do we measure it? This course explores these questions from a multidisciplinary perspective that includes computer science, economy, social science, among others. The sessions are organized around broad themes related to the value of data. A typical session will consist of a short introduction by the instructor, followed by a paper discussion (students are expected to read the assigned papers ahead of the class), and finishing with a discussion about individual projects. The course can be taken pass-fail or for a letter grade. For a letter grade, you need to complete an individual, quarter-long project. You also need to attend classes, participate in discussions, and scribe for two/three classes. For pass-fail, you do not need to complete the individual project but all other requirements apply.

**CMSC 35490. Special Topics in Machine Learning. 100 Units.**

Learned emulators leverage neural networks to increase the speed of physics simulations in climate models, astrophysics, high-energy physics, and more. Recent empirical results have illustrated that these emulators can speed up traditional simulations by up to eight orders of magnitude. However, little is understood about these emulators. While it is possible that recent results are representative of what is possible in most settings, a more likely scenario is that these approaches are more effective for some simulators than others, and that learned emulators achieve strong average-case performance but fail to capture rare but important phenomena. In this graduate seminar course we will provide an overview and investigate recent literature on this topic, focusing on the following questions: 1. Introduction to learned emulators: how do they work, where have they been successful so far and what are the goals in this field? 2. Two different paradigms of learned emulation: physics vs. data driven. What are the advantages and pitfalls of each? 3. Robustness of emulation to noise: what is known so far? 4. Parameter estimation: how to handle parameter uncertainty? We will provide a list of papers covering the above topics and students will be evaluated on in-class presentations.

Topics covered: basic matrix decompositions LU, QR, SVD; Gaussian elimination and LU/LDU decompositions; backward error analysis, Gram-Schmidt orthogonalization and QR/complete orthogonal decompositions; solving linear systems, least squares, and total least squares problem; low-rank matrix approximations and matrix completion. We shall also include a brief overview of stationary and Krylov subspace iterative methods; eigenvalue and singular value problems; and sparse linear algebra.
