Like many innovators, Hagit Messer-Yaron had a life-changing concept whereas doing one thing mundane: Speaking with a colleague over a cup of espresso. The IEEE Life Fellow, who in 2006 was head of Tel Aviv College’s Porter College of Environmental Research, was on the faculty’s cafeteria with a meteorological researcher. He shared his struggles with discovering high-resolution climate knowledge for his local weather fashions, that are used to forecast and observe flash floods.
Predicting floods is essential for rapidly evacuating residents in affected areas and defending properties and companies towards harm.

Her colleague “stated researchers within the area had restricted measurements as a result of the gear meteorologists used to gather climate knowledge—together with radar satellites—is dear to buy and preserve, particularly in creating international locations,” Messer-Yaron says.
Due to that, she says, high-resolution knowledge about temperature, air high quality, wind pace, and precipitation ranges is usually inconsistent—which is an issue when making an attempt to supply correct fashions and predictions.
An knowledgeable in sign processing and mobile communication, Messer-Yaron got here up with the thought of utilizing present wi-fi communication indicators to gather climate knowledge, as communication networks are unfold throughout the globe.
In 2006 she and her analysis workforce developed algorithms that course of and analyze knowledge collected by communication networks to observe rainfall. They measure the distinction in amplitude of the indicators transmitted and acquired by the methods to extract knowledge wanted to foretell flash floods.
The strategy was first demonstrated in Israel. Messer-Yaron is working to combine it into communication networks worldwide.
For her work, she acquired this 12 months’s IEEE Medal for Environmental and Security Applied sciences for “contributions to sensing of the surroundings utilizing wi-fi communication networks.” The award is sponsored by Toyota.
“Receiving an IEEE medal, which is the highest-level award you will get inside the group, was actually a shock, and I used to be extraordinarily blissful to [receive] it,” she says. “I used to be proud that IEEE was capable of consider and see the potential in our expertise for public good and to reward it.”
A ardour for instructing
Rising up in Israel, Messer-Yaron was excited by artwork, literature, and science. When it got here time to decide on a profession, she discovered it tough to resolve, she says. Finally, she selected electrical engineering, figuring it might be simpler to take pleasure in artwork and literature as hobbies.
After finishing her obligatory service within the Israel Protection Forces in 1973, she started her undergraduate research at Tel Aviv College, the place she discovered her ardour: Sign processing.
“Electrical engineering is a really broad matter,” she says. “As an undergrad, you be taught all of the elements that make up electrical engineering, together with utilized physics and utilized arithmetic. I actually loved utilized arithmetic and shortly found sign processing. I discovered it fairly superb how, by utilizing algorithms, you may direct indicators to extract info.”
She graduated with a bachelor’s diploma in EE in 1977 and continued her training there, incomes grasp’s and doctoral levels in 1979 and 1984. She moved to the US for a postdoctoral place at Yale. There she labored with IEEE Life Fellow Peter Schultheiss, who was recognized for his analysis in utilizing sensor array methods in underwater acoustics.
Impressed by Schultheiss’s ardour for instructing, Messer-Yaron determined to pursue a profession in academia. She was employed by Tel Aviv College as {an electrical} engineering professor in 1986. She was the primary girl in Israel to change into a full professor within the topic.
“Being a school member at a public college is the very best job you are able to do. I didn’t make some huge cash, however on the finish of every day, I regarded again at what I did [with pride].”
For the subsequent 14 years, she carried out analysis in statistical sign processing, time-delay estimation, and sensor array processing.
Her ardour for instructing took her all over the world as a visiting professor at Yale, the New Jersey Institute of Know-how, the Institut Polytechnique de Paris, and different colleges. She collaborated with colleagues from the schools on analysis tasks.
In 1999 she was promoted to director of Tel Aviv College’s undergraduate electrical engineering program.
A 12 months later, she was supplied a possibility she couldn’t refuse: Serving as chief scientist for the Israeli Ministry of Science, Tradition, and Sports activities. She took a sabbatical from instructing and for the subsequent three years oversaw the nation’s science coverage.
“I imagine [working in the public sector] is a part of our obligation as college members, particularly in public universities, as a result of that makes you a public mental,” she says. “Working for the federal government gave me a broad view of many issues that you just don’t see as a professor, even in a big college.”
When she returned to the college in 2004, Messer-Yaron was appointed because the director of the brand new faculty of environmental research. She oversaw the allocation of analysis funding and spoke with researchers individually to raised perceive their wants. After having espresso with one researcher, she realized there was a have to develop higher weather-monitoring expertise.

Utilizing sign processing to observe climate
As a result of the planet is warming, the danger of flash floods is steadily growing. Hotter air holds extra water—which ends up in heavier-than-usual rainfall and ends in extra flooding, in keeping with the U.S. Environmental Safety Company.
Information about rainfall is usually collected by satellite tv for pc radar and ground-based rain gauges. Nevertheless, radar photos don’t present researchers with exact readings of what’s occurring on the bottom, in keeping with an Ensia article. Rain gauges are correct however present knowledge from small areas solely.
So Messer-Yaron set her sights on creating expertise that connects to mobile networks near the bottom to offer extra correct measurements, she says. Utilizing present infrastructure eliminates the necessity to construct new climate radars and climate stations.
Communication methods routinely report the transmitted sign stage and the acquired sign stage, however rain can alter in any other case easy wave patterns. By measuring the distinction within the amplitude, meteorologists might extract the information needed to trace rainfall utilizing the sign processing algorithms.
In 2005 Messer-Yaron and her group efficiently examined the expertise. The next 12 months, their “Environmental Monitoring by Wi-fi Communication Networks” paper was revealed in Science.
The algorithm is being utilized in Israel in partnership with all three of the nation’s main mobile service suppliers. Messer-Yaron acknowledges, nevertheless, that negotiating offers with mobile service corporations in different international locations has been tough.
To increase the expertise’s use worldwide, Messer-Yaron launched a analysis community by means of the European Cooperation in Science and Know-how (COST), known as an opportunistic precipitation sensing community generally known as OPENSENSE. The group connects researchers, meteorologists, and different specialists all over the world to collaborate on integrating the expertise in members’ communities.
Since creating the expertise, Messer-Yaron has held quite a lot of jobs together with president of the Open College of Israel and vice chair of the nation’s Council for Larger Training, which accredits tutorial establishments.
She is sustaining her hyperlink with Tel Aviv College right this moment as a professor emerita.
“Being a school member at a public college is the very best job you are able to do,” she says. “I didn’t make some huge cash, however on the finish of every day, I regarded again at what I did [with pride]. Due to the tutorial freedom and the autonomy I had, I used to be capable of do many issues along with instructing, together with analysis.”
To proceed her work in creating expertise to observe climate occasions, in 2016, she helped discovered ClimaCell, now Tomorrow.io, primarily based in Boston. The startup goals to make use of wi-fi communication infrastructure and IoT gadgets to gather real-time climate knowledge. Messer-Yaron served as its chief scientist till 2017.
She continues to replace the unique algorithms together with her college students, most lately with machine studying capabilities to extract knowledge from bodily measurements of the sign stage in communication networks.
A world engineering neighborhood
When Messer-Yaron was an undergraduate pupil, she joined IEEE on the suggestion of certainly one of her professors.
“I didn’t assume a lot about the advantages of being a member till I grew to become a graduate pupil,” she says. “I began attending conferences and publishing papers in IEEE journals, and the group grew to become my skilled neighborhood.”
She is an lively volunteer and a member of the IEEE Sign Processing Society. From 1994 to 2010 she served on the society’s Sign Processing Concept and Strategies technical committee. She was affiliate editor of IEEE Sign Processing Letters and IEEE Transactions on Sign Processing. She is a member of the editorial boards of the IEEE Journal of Chosen Matters in Sign Processing and IEEE Transactions on Sign Processing.
Previously 10 years, she’s been concerned with different IEEE committees together with the conduct evaluation, ethics and member conduct, and world public coverage our bodies.
“I don’t see my profession or my skilled life with out the IEEE,” she says
