Not like many budding engineers, Okay.J. Ray Liu wasn’t impressed to enter the sector by tinkering with electronics or following within the footsteps of a member of the family. Rising up in Taichung, Taiwan, he answered his authorities’s name for college kids to grow to be electrical engineers to assist manufacture semiconductors within the Nineteen Seventies, when the nation’s economic system was struggling.
“College students who had been good in math, science, and physics all wished to be {an electrical} engineer as a result of that was the highest precedence of the federal government,” Liu says. “That’s how I bought into engineering. Now Taiwan is a world chief in semiconductors.”

However by the point he graduated from college in 1983, semiconductor services had been nonetheless beneath building, so there have been no jobs obtainable.
As an alternative, he went on to have a profitable profession as an educator and entrepreneur within the United States.
For 31 years, he was a professor of info know-how and a digital sign processing researcher on the College of Maryland in Faculty Park till he retired in 2021.
Liu was the chairman, CEO, and CTO of Origin Wi-fi, a startup he based in Rockville, Md. Origin, which was acquired by ADT in February, pioneers synthetic intelligence for wi-fi sensing and indoor monitoring.
Liu, an IEEE Fellow, is an lively IEEE volunteer who served because the group’s president in 2022.
IEEE honored him with this 12 months’s Haraden Pratt Award for “transformative and impactful management.”
Liu is credited with growing the variety of nominees for IEEE’s Fellow program, which is the best degree of membership. He additionally led the hassle to realign the group’s areas geographically to make sure extra equitable international illustration on the IEEE Board of Administrators.
He obtained the Pratt honor on 24 April throughout a ceremony in New York Metropolis. The IEEE Basis sponsored the Board-level award.
“Greater than something, I share the consideration with the volunteers and workers I had the privilege to work alongside,” he says. “Our laborious work is fueled by our shared devotion to this skilled dwelling we love and take care of a lot.”
Within the Nineteen Seventies, Taiwan’s policymakers determined to enhance the nation’s economic system by pivoting from making merchandise resembling footwear and umbrellas to manufacturing electronics.
The business bought its begin in 1976 when RCA, a serious electronics firm on the time, agreed to switch licensed semiconductor processes to Taiwan’s Industrial Know-how Analysis Institute. ITRI spun off a number of semiconductor-related firms together with the Taiwan Semiconductor Manufacturing Co. TSMC, launched in 1987, is the world’s largest devoted semiconductor foundry.
Liu graduated in 1983 with a bachelor’s diploma in electrical engineering from Nationwide Taiwan College, in Taipei. On the time, there have been no semiconductor firms to work for, he says.
“These days, most of the nation’s college graduates go proper to TSMC to get a job,” he says. “However again then, there was no actual job market.
“Most of my classmates—together with me—got here to the U.S. for graduate research. Many people stayed and, over the past three to 4 a long time, contributed to the event of digital laptop communication know-how within the U.S.”
Liu left Taiwan after a two-year obligatory stint within the Republic of China Armed Forces to attend the College of Michigan, in Ann Arbor, the place in 1987 he earned a grasp’s diploma in electrical engineering.
“If I may also help make IEEE a greater skilled dwelling for future members, that’s one thing that I pays again to IEEE.”
He went on to earn a Ph.D. in electrical, electronics, and communications engineering in 1990 from the College of California, Los Angeles. His curiosity in digital sign processing and very-large-scale integration (VLSI) was sparked whereas at UCLA. Immediately VLSI powers all fashionable electronics.
“After I was a graduate pupil, there was no wi-fi communication. All people had a landline,” he explains.
VLSI was an essential, lively analysis discipline on the time.
“My analysis curiosity was digital sign processing,” he says. “Someday I noticed a e book on VLSI sign processing on my professor’s bookshelf. I instantly thought to myself: That’s the discipline I need to pursue.
“VLSI is one lane, digital sign processing is the opposite, and there’s a bridge linking the 2. I used to be keen on each areas, so I did my Ph.D. thesis on VLSI sign processing.”
After graduating, Liu joined the College of Maryland, the place he’s credited with establishing its sign processing analysis program.
Along with educating, he carried out analysis on a broad vary of sign processing and communication facets. The subjects embody bioinformatics, recreation concept, sign processing algorithms and architectures, and wi-fi sensing and communications.
He has authored greater than 10 books and 900 papers, and he holds 250 patents. Yow will discover his analysis papers within the IEEE Xplore Digital Library.
Ambient-sensing trailblazer
Liu is taken into account to be a pioneer within the discipline of ambient sensing. The know-how gathers environmental knowledge and is utilized in safety methods and health-monitoring gadgets.
He got here up with the thought, he says, whereas engaged on a mission in 2009 for the U.S. Navy. He was attempting to resolve an issue the Navy was having with the wi-fi communication methods utilized in its submarines. As a result of submarines are product of metallic, radio waves had been unable to penetrate the vessels’ compartments and as a substitute bounced round, creating interference, he says.
His answer was to make use of a comparatively unknown idea in physics: time-reversal sign processing. The method captures waves, resembling sound and electromagnetic alerts, and sends them again via the identical medium in reverse, flipping the sign from last-in to first-out, and re-emits them.
“Through the use of time-reversal feed, we may improve the signal-to-noise ratio by 4 instances,” he says. “That improved efficiency dramatically.”
He turned fascinated by the physics of time-reversal sign processing, he says, and puzzled how he may apply the idea to serve society. After three years of analysis, he got here up with the thought of utilizing wi-fi sensing purposes via ambient radio waves from surrounding Wi-Fi networks.
“I realized to show Wi-Fi networks into sensing networks that decipher our actions,” he says. “We may know the whole lot occurring round us—our motions, respiratory, heartbeat, even fall detection—with none wearables.”
By means of the college’s incubator, which inspires school to work on tasks with an influence on society, he launched Origin in 2013. The corporate’s Wi-FI and AI sensing know-how allows correct indoor monitoring, movement detection, and well being monitoring with out the necessity for wearable gadgets or cameras. Its merchandise, together with its distant affected person monitoring, obtained three innovation awards on the 2020 and 2021 Shopper Electronics exhibits, together with one for finest innovation.
Discovering his skilled dwelling
Liu joined IEEE in 1986 as a graduate pupil to entry its analysis papers, he says.
“Should you didn’t be a part of an IEEE society, you didn’t get its journal—which meant that you just couldn’t learn probably the most up-to-date analysis papers,” he says. “So, I joined the IEEE Sign Processing Society. After I attended my first sign processing convention, I knew I had discovered an expert dwelling. I met many like-minded folks, and collectively, we constructed an expert dwelling for our members worldwide.”
He turned an lively volunteer, holding prime management positions together with 2012–2013 president of the Sign Processing Society and 2016–2017 director of IEEE Division IX, which covers societies targeted on sign processing, knowledge transmission, navigation, and transportation. In 2019 he was vice chairman of the Technical Actions Board.
In 2022 he served as IEEE president and CEO. The three accomplishments throughout his time period he says he’s most happy with are growing the prize cash for the IEEE Medal of Honor, overseeing the realignment of IEEE areas, and establishing larger monetary transparency.
The rationale for growing the prize for IEEE’s highest award—from US $50,000 to $2 million—in 2025, he says, was to underscore the significance of the applied sciences the IEEE neighborhood develops. These improvements embody semiconductors, the Web, and the GPU. The cash for the Medal of Honor now exceeds that of the Nobel Prize, which carries an award of roughly $1 million.
“We’d like the entire world to know the IEEE neighborhood has made probably the most influence on society within the final century,” Liu says. “However, we didn’t obtain the eye and respect we deserved, so we wanted to assist ourselves. We wish the entire world to know what our contributions are.”
His subsequent achievement was realigning IEEE’s areas. Throughout the previous a number of years, membership in Area 10, which covers nations in Asia and the Pacific, has grown from 10 % of whole membership to almost 40 %, he says. It’s the largest and most populous of IEEE’s geographic areas, however its members weren’t equitably represented on the Board of Administrators. Every area had one consultant on the Board.
“The area has 40 % of the members however solely makes up 10 % of the Board,” Liu says. “That didn’t make sense to a variety of us.”
The IEEE Board in 2022 accredited area realignment. The whole variety of areas stays at 10, however their group is altering. Efficient 1 January 2028, the six U.S.-based areas can be consolidated into 5, and Area 10 can be break up into two. IEEE will now not use the Area 1 designation. The brand new Area 2 will signify the Northeastern and Japanese U.S. Area 10 will cowl North Asia, and the brand new Area 11 will signify South Asia and the Pacific.
Liu additionally succeeded in main a motion that persuaded the IEEE Board to spend money on a greater monetary reporting system to have a clearer understanding of the group’s funds. A extra fashionable system now tracks banking transactions, contracts, expense experiences, and different spending.
“Now we all know precisely the place the cash comes from and the place it’s spent,” he says, “in order that we will make extra knowledgeable selections.
“If I may also help make IEEE a greater skilled dwelling for future members, that’s one thing that I pays again to IEEE,” he provides. “I really admire what IEEE supplied me. From pupil to professor to a longtime chief, at each stage, it supplied me completely different alternatives to develop. That’s the reason I labored very laborious after I was president to ensure everyone realizes it’s a skilled dwelling for our total profession.”
