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 financial system was struggling.
“College students who had been good in math, science, and physics all needed to be {an electrical} engineer as a result of that was the highest precedence of the federal government,” Liu says. “That’s how I obtained into engineering. Now Taiwan is a world chief in semiconductors.”

However by the point he graduated from college in 1983, semiconductor amenities had been nonetheless underneath building, so there have been no jobs obtainable.
As a substitute, 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 trouble to realign the group’s areas geographically to make sure extra equitable international illustration on the IEEE Board of Administrators.
He acquired 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 employees I had the privilege to work alongside,” he says. “Our exhausting 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 financial system by pivoting from making merchandise comparable to footwear and umbrellas to manufacturing electronics.
The business obtained 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, lots 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, during the last three to 4 a long time, contributed to the event of digital pc communication know-how within the U.S.”
Liu left Taiwan after a two-year necessary 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 help make IEEE a greater skilled dwelling for future members, that’s one thing that I will pay 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. Right this moment VLSI powers all fashionable electronics.
“Once I was a graduate pupil, there was no wi-fi communication. Everyone had a landline,” he explains.
VLSI was an vital, lively analysis subject on the time.
“My analysis curiosity was digital sign processing,” he says. “At some point I noticed a e book on VLSI sign processing on my professor’s bookshelf. I instantly thought to myself: That’s the subject I wish to pursue.
“VLSI is one lane, digital sign processing is the opposite, and there’s a bridge linking the 2. I used to be inquisitive about 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 instructing, he carried out analysis on a broad vary of sign processing and communication features. The matters embrace bioinformatics, sport principle, 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. You could find his analysis papers within the IEEE Xplore Digital Library.
Ambient-sensing trailblazer
Liu is taken into account to be a pioneer within the subject of ambient sensing. The know-how gathers environmental information and is utilized in safety techniques 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 unravel an issue the Navy was having with the wi-fi communication techniques utilized in its submarines. As a result of submarines are fabricated from steel, 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 approach captures waves, comparable to sound and electromagnetic indicators, and sends them again by 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 enhance 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 by 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 all the pieces occurring round us—our motions, respiration, heartbeat, even fall detection—with none wearables.”
By the college’s incubator, which inspires school to work on initiatives 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, acquired three innovation awards on the 2020 and 2021 Shopper Electronics reveals, together with one for greatest innovation.
Discovering his skilled dwelling
Liu joined IEEE in 1986 as a graduate pupil to entry its analysis papers, he says.
“If you happen to didn’t be 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. Once I attended my first sign processing convention, I knew I had discovered knowledgeable dwelling. I met many like-minded folks, and collectively, we constructed knowledgeable dwelling for our members worldwide.”
He turned an lively volunteer, holding high management positions together with 2012–2013 president of the Sign Processing Society and 2016–2017 director of IEEE Division IX, which covers societies centered on sign processing, information 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 pleased with are growing the prize cash for the IEEE Medal of Honor, overseeing the realignment of IEEE areas, and establishing higher 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 embrace 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 want the entire world to know the IEEE neighborhood has made probably the most influence on society within the final century,” Liu says. “Nonetheless, we didn’t obtain the eye and respect we deserved, so we would have liked to assist ourselves. We would like 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 international locations 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 numerous us.”
The IEEE Board in 2022 authorised area realignment. The entire 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 cut up into two. IEEE will not use the Area 1 designation. The brand new Area 2 will characterize the Northeastern and Jap U.S. Area 10 will cowl North Asia, and the brand new Area 11 will characterize South Asia and the Pacific.
Liu additionally succeeded in main a motion that persuaded the IEEE Board to put money into 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 stories, 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 are able to make extra knowledgeable choices.
“If I may help make IEEE a greater skilled dwelling for future members, that’s one thing that I will pay again to IEEE,” he provides. “I actually admire what IEEE provided me. From pupil to professor to a longtime chief, at each stage, it provided me totally different alternatives to develop. That’s the reason I labored very exhausting after I was president to verify all people realizes it’s a skilled dwelling for our total profession.”
