Asif Khan

Asif Khan has been named as a recipient of the NSF CAREER Award. He is an assistant professor in the Georgia Tech School of Electrical and Computer Engineering (ECE) and also holds a courtesy appointment in the School of Materials Science and Engineering.

The title of Khan’s award is “Antiferroelectric Negative Capacitance Transistors for Ultra-low Power Computing,” and it will start on March 15, 2021 and end on February 28, 2026. 

Today's society is experiencing an unprecedented growth of its digital footprint – be it in the form of uploading a photo on Facebook, live-streaming a teaching module to a massive global audience on YouTube, or commandeering a revolution via Twitter. This convenience of modern computing, however, comes with a steep cost in terms of energy use and environmental impact. Today, the global information infrastructure, such as data centers, emit as much greenhouse gases as that of the state of Nevada or a country, such as The Netherlands or Malaysia, and constitute around 1 percent of world-wide electricity demand. According to scientific estimates, this fraction may increase to a double digit percentage in the next 15-20 years. 

At the core of this predicament lies the fact that the fundamental building blocks of digital hardware – the transistors – have long been overdue for a prime upgrade in terms of their energy efficiencies. The proposed research aims to explore an energy-efficient transistor concept – known as a negative capacitance field-effect transistor, using a new class of materials called antiferroelectric oxides. 

Khan joined the ECE faculty in 2017. His research is on advanced semiconductor devices—devices that will shape the future of computing in the post-scaling era. His research group currently focuses on ferroelectric devices, in all aspects ranging from materials physics, growth, and electron microscopy to device fabrication, all the way to ferroelectric circuits and systems for artificial intelligence/machine learning/data-centric applications. Khan’s Ph.D. work led to the proof-of-concept demonstration of the negative capacitance phenomenon in ferroelectric materials, which can reduce the power dissipation in electronic devices below the ‘fundamental’ thermodynamic limit. This culminated in the initial development of the field of negative capacitance.

Khan has published 2 book chapters and 70 journal and peer-reviewed conference publications, and he has given 20 invited talks and tutorials at premier microelectronics and ferroelectric conferences. Khan currently has one patent pending at Intel. 

Khan’s awards include the NSF CAREER award (2021), Intel Rising Star Award (2020), Qualcomm Innovation Fellowship (2012), TSMC Outstanding Student Research Award (2011), and the University Gold Medal from Bangladesh University of Engineering and Technology (2011). His group at Georgia Tech consists of six Ph.D. students and three research engineers, many of whom won Institute-level and international awards, including an IEEE Electron Devices Society (EDS) Masters Student Fellowship (2020). Khan’s research is supported by the National Science Foundation, the Defense Advanced Research Projects Agency, the Semiconductor Research Corporation, and Intel Corporation. 

Khan has also developed a graduate course, ECE 8863A Quantum Computing Devices and Hardware, as a part of the campus wide response to the national prioritization of quantum computing, known as the National Quantum Initiative Act (NQIA) that was signed by the U.S. president in 2018. Khan recently received the Class of 1934 CIOS Honor Roll award for excellence in teaching this course in Fall 2020.

Sam Coogan

Sam Coogan has received a National Science Foundation CAREER Award for his research project entitled “Correct-By-Design Control of Traffic Flow Networks.”

Coogan is an assistant professor in the Georgia Tech School of Electrical and Computer Engineering and holds a joint appointment in the School of Civil and Environmental Engineering. He joined Georgia Tech in August 2017 after serving as an assistant professor in the Department of Electrical Engineering at the University of California, Los Angeles.

Today's cities accommodate more people than ever before, leading to transportation networks that operate at or near capacity. In addition, the next generation of transportation systems will include connected vehicles, connected infrastructure, and increased automation, and these advances must coexist with legacy technology into the foreseeable future. Accommodating these rapidly developing advancements requires smarter and more efficient use of existing infrastructure with guarantees of performance, safety, and interoperability.

The goal of Coogan’s project is to develop fundamental theory and domain-driven techniques for controlling traffic flow in large-scale transportation networks. Recent advances in inexpensive sensors, wireless technology, and the Internet of Things (IoT) enable real-time connectivity of vehicles and infrastructure that offers abundant data and unprecedented opportunities for efficient and optimized transportation systems.

The main technical goal of the project is to develop techniques and algorithms that are correct-by-design, ensuring that these transportation systems satisfy required operating specifications. In pursuit of this goal, the project will first develop models of traffic flow from rich data streams and then will leverage these models to enable scalable control approaches.

In addition, this project will integrate a forward-looking education plan that will introduce a Control Grand Challenge design competition in the introductory course in control theory for undergraduates. For this competition, students will design a controller for an autonomous, scale-model car and then compete with their design.

Omer Inan

Omer Inan has received a National Science Foundation CAREER Award for his research project entitled “Wearable Joint Sounds Sensing for Children with Juvenile Idiopathic Arthritis.” Inan is an assistant professor in the Georgia Tech School of Electrical and Computer Engineering (ECE).

Juvenile idiopathic arthritis (JIA) is the most common form of childhood arthritis and is a disability affecting more than 50,000 children in the United States. JIA’s presentation and progression can vary greatly from person to person, and a multitude of new treatment options are available for the various stages of the disease. Diagnosing, tracking, and treating JIA on a patient-by-patient basis is difficult because of a lack of tools for assessing the condition.

This project will focus on researching wearable joint health sensing systems for persons with JIA that will allow for continuous assessment both in and out of the clinic. The project will also include several educational objectives which are closely integrated with the research:

  • a team of undergraduate researchers, particularly from underrepresented groups, will be formed to work closely with a graduate student on the sensing brace design;
  • authentic learning modules will be developed based on the collected data for the PI’s courses; and
  • through an existing program at Georgia Tech, K-12 teachers will be hosted over the summer in Inan’s lab to develop science and engineering curriculum modules for their courses that are infused with art.

Inan is a member of the Parker H. Petit Institute for Bioengineering and Bioscience and a program faculty member for the Interdisciplinary Bioengineering Graduate Program. His most recent honors include the ECE Outstanding Junior Faculty Member Award (2018), the Georgia Tech Sigma Xi Young Faculty Award (2017), and the Lockheed Dean’s Excellence in Teaching Award in (2016). He is also a senior member of IEEE.
