UC Davis distinguished professor Walter Soares Leal of the Department of Molecular and Cellular Biology and a former chair of the Department of Entomology, was inducted as a Fellow of the National Academy of Inventors (NAI) at a June ceremony in Phoenix, Ariz.
A leading global scientist and inventor in the field of insect olfaction and communication, Leal was elected an NAI Fellow in 2019 for his impact in the fields of molecular, cellular biology, and entomology, but due to the COVID pandemic, the organization cancelled the 2020 Phoenix ceremony. Travel restrictions prevented him from attending the 2021 ceremony in Tampa, Fla. Elected Fellows are required to attend the induction ceremony within two years of election in order to receive their award.
NAI singles out outstanding inventors for their “highly prolific spirit of innovation in creating or facilitating outstanding inventions that have made a tangible impact on the quality of life, economic development, and welfare of society.” Election to NAI Fellow is the highest professional distinction accorded solely to academic inventors. The NAI Fellow program has 1,403 Fellows worldwide representing more than 250 prestigious universities and governmental and non-profit research institutes.
“I attended with my wife, Beatriz, and daughter Helena and son Gabriel – both have co-authored papers in the lab, so they represent all visiting scholars, collaborators, postdocs, project scientists, graduate students, and undergraduate students in my lab,” Leal said.
UC Davis chancellor emerita Linda Katehi, an NAI fellow inducted in 2012, nominated Leal for the honor for his “novel, sustainable and continued contributions to the field of entomology and for their greater implications in molecular and cellular biology and the understanding of disease and prevention.” At the time, Leal held 28 Japanese and two U.S. patents.
Leal is the second faculty member affiliated with the Department of Entomology and Nematology to be selected an NAI fellow. Distinguished professor Bruce Hammock, who holds a joint appointment with the Department of Entomology and Nematology and the UC Davis Comprehensive Cancer Center, received the honor in 2014.
Leal, an expert in insect communication investigates how insects detect odors, connect and communicate within their species; and detect host and non-host plant matter. His research, spanning three decades, targets insects that carry mosquito-borne diseases as well as agricultural pests that damage and destroy crops. He and his lab drew international attention with their discovery of the mode of action of DEET, the gold standard of insect repellents.
Leal was recently elected chair of the International Congress of Entomology Council, which selects a country to host the congress every four years and which supports the continuity of the international congresses of entomology. Leal succeeds prominent entomologist May Berenbaum of the University of Illinois, Urbana-Champaign, editor-in-chief of the journal, Proceedings of the National Academy of Sciences and a 2014 recipient of the National Medal of Science.
“I have big shoes to fill,” he said.
Ironically, COVID derailed the 2020 NAI ceremony, and Leal–recipient of the Academic Senate’s 2022 Distinguished Scholarly Public Service Award for his series of four global webinars educating the public about COVID-19–contracted the disease while in Phoenix for the 2022 ceremony.
“I was treated with Paxlovid, rebounded, and am now fully recovered,” Leal said.
Leal’s name is currently on the ESA ballot to become an Honorary Member, the highest ESA honor. The Royal Entomological Society named him an Honorary Fellow in 2015.
A native of Brazil, educated in Brazil and Japan, and fluent in Portuguese, Japanese and English, Leal received his master’s degree and doctorate in Japan: his master’s degree at Mie University in 1987, and his doctorate in applied biochemistry at Tsukuba University in 1990. Leal then conducted research for 10 years at Japan’s National Institute of Sericultural and Entomological Science and the Japan Science and Technology Agency before joining the faculty of the UC Davis Department of Entomology in 2000. He chaired the department from July 2006 to February 2008.
Leal co-chaired the 2016 International Congress of Entomology meeting, “Entomology Without Borders,” in Orlando, Fla., that drew the largest delegation of scientists and experts in the history of the discipline: 6682 attendees from 102 countries.
Among his many other honors, Leal is a Fellow of ESA, the American Association for the Advancement of Sciences and the California Academy of Sciences. He is a past president of the International Society of Chemical Ecology and corresponding member of the Brazilian Academy of Sciences. In 2019, ESA selected him to present its annual Founders’ Memorial Lecture, the first UC Davis scientist selected to do so.
