Computer Engineering

The biggest companies in the world—Apple, Amazon, Google, Facebook, Microsoft—are built on the technologies developed by computer engineers and computer scientists. But computer engineers are vital not only to those giant tech companies. No modern company can survive without the software and the hardware you will learn to design and to build in Computer Engineering at Purdue.  As a computer engineer you will master technologies that can address critical societal needs in domains such as health care, national security, space research, technology for special needs children, and more. Computer Engineers learn about the full computing stack. They learn about hardware—from circuits to microcontrollers to general-purpose microprocessors. They learn about systems software—the operating systems, programming languages, compilers, and networking software that no modern computer can be without. They learn about algorithms that transform concepts to actions. And they learn about the grand challenges that drive modern computing: security, artificial intelligence, the Internet of Things, and beyond. Computer Engineering faculty are at the forefront of tackling these challenges through their path-breaking research which leads to high-impact inventions and which are translated to what they teach in the classrooms. Unlock your potential to shape the future of computing with Computer Engineering at Purdue.

Dependable Computing Systems Lab (DCSL)

We design reliable and secure systems. In our lab, big data techniques are applied to systems at large scales. Our work is motivated by the fact that systems are increasing in scale, both in terms of the number of executing elements and the amount of data that they need to process and existing dependability techniques are increasingly failing to meet the demands of such scaling. Further, systems are heterogeneous, both in terms of hardware (GPU, DSP, FPGA, etc. coupled with traditional CPUs) and software (software from multiple parties being integrated to provide end-user functionality). Our application contexts come from various domains, many from our industrial colleagues. These include: security-critical enterprise systems, mobile and wearable systems, cloud platforms, and cyber physical systems. Our solutions win awards at the top conferences and show up in industrial prototypes and products.

Haptic Interface Research Lab (HIRL)

HIRL is devoted to the investigation of the underlying principles for the design, development and evaluation of human-machine interfaces, with an emphasis on haptic interfaces. It is equipped with several unique equipment, including a real-time pressure-distribution measurement system, two force feedback devices, and several vibrotactile displays developed in-house.

High-Efficiency, Low-Power Systems Group (HELPS)

HELPS develops the technology to improve the efficiency and performance of computing systems. Our research includes cloud and mobile computing, image/video processing, resource management. Energy efficiency is one of the "enablers" in computing and longer battery lifetime has been consistently ranked as at the top of mobile users' most-wanted improvement. HELPS integrates the convenience of mobile computing and the abundant resources in cloud computing for providing better performance at lower energy consumption. HELPS is constructing a platform using globally deployed network cameras for mobile users to obtain real-time views of the world.

Internet Systems Lab (ISL)

Our focus is on research related to the Internet and Distributed Systems. Our current research focuses on Cloud Computing. Specifically, we are looking at how best to architect interactive web-applications over geographically distributed data-centers, and how to partition functionality between smart-phones and the cloud. We are also looking at Software Defined Networking and Enterprise Network Configuration Management. In the past, we have conducted research in the areas of Peer to Peer Systems, and Internet video Content Distribution architectures. Our research has benefited by support from NSF, Cisco, AT&T, and Microsoft. Many of the challenges we address are motivated by real-world experience, require insights into operations of distributed systems at Internet scales, and can have substantial real world impact.

Machine Learning, Planning, and Reasoning

We study new methods for automating fundamental cognitive processes such as learning, planning, and reasoning. Our focus is on challenge problems for which previous artificial intelligence research has dramatically failed to produce human-level performance---for example, learning the meaning of words by seeing them used in context, or learning to play a new game better by playing it repeatedly. We actively examine the relationship between the machine's representation of the problem and its solution success. Our applied projects include work in the areas of branch prediction in computer architecture, control of computer networks, and anomaly detection in computer security.

Purdue Programming Languages Research Group

PurPL is the cross-departmental umbrella group for programming languages research at Purdue University. PurPL research groups push the boundaries of every area in programming languages, software engineering, formal methods, and systems: PL theory, design, and implementation, language-based security, compiler optimizations, verification, program synthesis, and more. But we do more than fundamental research: we bring PL ideas to bear on a wide range of areas, including big data, security, education, and computational science.

System Software

System software, including operating systems, distributed systems, and runtime, constitutes the core of modern computer systems. With diverse perspectives, we are building the next-generation system software for a wide spectrum of computers – from mobile devices in your pocket to “big iron” in data centers – towards making them performant, efficient, and reliable.
