The awards are designed to strengthen Stony Brook’s prominence by funding senior field-leading hires in AI and cybersecurity. In AI, Stony Brook will focus on applications in medicine, smart environments and infrastructures, as well as core AI and machine-learning technologies. In cybersecurity, the focus will be on hardware security, operating systems security, big data security, and mobile security and on the National Security Institute, the existing cybersecurity cluster in Stony Brook.

“Stony Brook has consistently played a nationally prominent role in AI and cybersecurity research,” said Samuel L. Stanley Jr., President of Stony Brook University. “We have recently undertaken a bold, strategic initiative in engineering-driven medicine for which AI technology and cybersecurity of medical data are significant drivers. This grant will enable us to recruit leading faculty researchers, and invest added resources with our current researchers as they together pursue excellence in advancing these fields.”

The envisioned Institute will serve as a hub for all AI related research on campus and position Stony Brook as a leader in AI research. In addition to carrying out funded research, the Institute will catalyze new educational programs generating professionals for the AI-driven economy of the future. This will range from core technical programs (e.g., interdisciplinary data science and engineering or machine learning) to science communication, technology policy and entrepreneurship programs. The Institute will also stimulate regional economy by providing local industry and entrepreneurs with new technology training and new graduates to hire.

Space for the new hires will be allocated in the new Computer Science building commissioned in 2015, the upcoming MART (Medicine and Research Translation) building. Contingent upon AI cluster hire needs, additional space will be available in existing centers, including the Center of Excellence in Wireless & Information Technology (CEWIT), the Institute for Advanced Computational Science (IACS) and I-DIME, the new building focused on discovery and innovation in medicine and engineering to be located in the Stony Brook University Research and Development Park.

PhD student wins Social Policy Research Grant

Jamie Sommer, a PhD candidate in the Department of Sociology at Stony Brook University, has received a research grant from the Horowitz Foundation for Social Policy for her work, “Is Bilateral Environmental Aid Effective? A Cross-National Analysis of Forest Loss.” Sommer is one of 20 award winners chosen by the board of trustees from 535 applications.

“I am honored to receive the Horowitz Foundation research grant to continue my work on analyzing the effectiveness of bilateral aid at reducing environmental harms cross-nationally,” said Sommer. “This project is part of my larger research narrative, which aims to understand the role of the state in reducing forest loss. In particular, this grant will help me theoretically and empirically test what types of foreign bilateral environmental aid are most effective, considering the internal political and economic characteristics of receiving nations. The findings will help donors implement policies to ensure the delivery of their funds and that projects are improving the environment and reducing forest loss. I hope my research will help inform the U.S. and other high-income nations in how to increase the effectiveness of their aid to limit the loss of our world’s forests.”

“This year the foundation saw a marked increase in not just the number of applications, but also the number of applicants holding citizenship in other countries, although surprisingly all recipients attend U.S. institutions,” said Horowitz Foundation Chair Mary E. Curtis. “The winners were chosen by the trustees for their potential to contribute to social policy on both a global and local level. As we look forward to celebrating our 20th year in 2018, we hope to continue aiding international scholars at home and abroad.”

SBU Research Helps SUNY Rank Among Top 100 Worldwide for Patents

SUNY ranked 38th in the “Top 100 Worldwide Universities Granted U.S. Utility Patents for 2016,” according to the National Academy of Inventors and Intellectual Property Owners Association, which publishes the ranking annually based on U.S. Patent and Trademark Office data.

SUNY campuses overall were awarded 57 U.S. utility patents. Among those from Stony Brook University is a redesigned a catheter developed by a multidisciplinary team led by Annie Rohan from the School of Nursing. The catheter incorporates LED lights to reduce the likelihood of infection after the device is inserted into a patient’s body.

“Catheter-related infections are a multibillion-dollar-a-year problem,” says Rohan. “Healthcare providers have addressed it with prophylactic antibiotics, handwashing, and techniques to maintain sterility, but up until now there hasn’t been a product that can successfully reduce infection risk once the device is in the body.”

“Across SUNY, our faculty and students partner to make groundbreaking discoveries in a broad spectrum of areas,” said SUNY Chancellor Nancy L. Zimpher. “Through more than 1,300 U.S. patents earned to date, SUNY research has led to hundreds of new technologies and advances that address society’s greatest challenges and have a positive impact on quality of life in New York and beyond. Congratulations to all those at SUNY whose important work has elevated us to this prominent world ranking.”

Study links late-night tweeting by NBA players to worse game performance

When pro ballers indulge in late-night tweetstorms, they aren’t just courting controversy: they could also be impacting their performance on-court.

A new study led by Stony Brook researchers suggests that NBA players had worse personal statistics in games that followed a late-night tweet.

Players scored on average about 1 point less in games following late-night tweets, and their shooting accuracy dropped 2.5 percentage points compared with their performance in games that did not follow late-night tweeting. After a late-night tweet, players also took fewer shots and had fewer rebounds, steals and blocks. “Using late-night tweeting activity as a proxy for being up late, we interpret these data to show that basketball skills are impaired after getting less sleep,” said lead investigator Jason J. Jones, PhD, Assistant Professor of Sociology at Stony Brook University in New York.

“While experimental studies have shown the impact of sleep deprivation on performance, this study uses big data to provide interpretable results on real-world performance of basketball players.”

According to the authors, most of the statistical changes following late-night tweets can be explained by fewer minutes played. Players had an average of 2 minutes less playing time following late-night tweeting.

“Our findings are relevant beyond just sports science research,” said study co-author Lauren Hale, PhD, Professor of Family, Population and Preventive Medicine in the Program in Public Health at Stony Brook University. “Our results demonstrate a broader phenomenon: to perform at your personal best, you should get a full night of sleep.”

The research team led by Jones and Hale merged two public sources of data for the study, analyzing Twitter account activity from 112 verified NBA players as well as basketball statistics from Yahoo Sports. The data, which included more than 30,000 tweets, were compiled across 7 basketball seasons from 2009 to 2016. To reduce the potential performance effects of changing time zones, the analysis included only games within the same time zone as the player’s home.

“Twitter is currently an untapped resource for late-night behavior data that can be used as a proxy for not sleeping,” said Jones. “We hope this will encourage further studies making use of time-stamped online behavior to study the effects of sleep deprivation on real-world performance.”

An Ancient Lake on Mars Was Able to Harbor a Variety of Lifeforms, Says SBU-Led Study

A Martian crater is providing more proof that the Red Planet may once have supported life, a Stony Brook geochemist and planetary scientist says in a recently published NASA study.

Sedimentary rocks from three locations on lower Mount Sharp on Mars examined by NASA’s Curiosity rover provide examples of different textures interpreted as sediments deposited at different depths within a long lived lake. This example exhibits thicker layers which occur at the edge of a lake where sediment-bearing water enters the lake, slows down and drops much of its sediment. Credit: NASA/JPL-Caltech/MSSS
The study led by Assistant Professor Joel Hurowitz offers perhaps the most significant evidence to date that an ancient lake on Mars had all the ingredients of a life-sustaining body of water.

Building on the 2013 discovery that Mars’ Gale crater contained a freshwater lake more than 3 billion years ago, Assistant Professor Joel Hurowitz led a team of 22 international scientists using findings beamed to Earth from NASA’s Curiosity rover to determine that the lake was stratified, meaning that depending on the depth, its water created several co-existing environments where life could flourish, much like the lakes on Earth.

“The diversity of environments in this Martian lake would have provided multiple opportunities for different types of microbes to survive, including those that thrive in oxidant-rich conditions, those that thrive in oxidant-poor conditions, and those that inhabit the interface between those settings,” Hurowitz said. “This type of oxidant stratification is a common feature of lakes on Earth, and now we’ve found it on Mars.”

Hurowitz is an assistant professor in Stony Brook’s Department of Geosciences, as well as the head of one of three laboratories inside the University’s Center for Planetary Exploration (CPEx), which brings students and faculty together to pave the way for future human exploration of our solar system through interdisciplinary study and hands-on science.

The study, titled Redox stratification of an ancient lake in Gale crater, Mars and published in the June 2 edition of Science, uses evidence retrieved by the Curiosity rover from the base of a mountain inside Gale crater. After examining the physical, chemical and mineral characteristics of the mountain’s rock layers, the team was able to not only determine that the ancient lake was stratified, but that ancient Mars itself experienced distinct climate change.

During the time Gale crater held lake water, climate conditions changed from colder and drier to warmer and wetter. This relatively short-term climate change took place within a longer climate evolution, during which Mars transitioned from warm, wet conditions that supported lakes, to the cold, arid planet we see through our telescopes today.

“These results give us unprecedented detail in answering questions about ancient environmental conditions on Mars,” said Curiosity Project Scientist Ashwin Vasavada of NASA’s Jet Propulsion Laboratory. “I’m struck by how these fascinating conclusions on habitability and climate took everything the mission had to offer: a set of sophisticated science instruments, multiple years and miles of exploration, a landing site that retained a record of the ancient environment, and a lot of hard work by the mission team.”

While evidence of life on Mars is still unknown, seeking signs of life there starts with studying the environment and its ability, in present or ancient times, to sustain life. Developments such as these achieved by Hurowitz and all co-authors on the study reinforce NASA’s strategy to use rovers to further investigate Mars.

Hurowitz’s involvement with NASA’s missions to Mars continues as he is also deputy principal investigator for the Planetary Instrument for X-ray Lithochemistry (PIXL), an instrument being developed within Stony Brook’s CPEx that will be part of the upcoming Mars 2020 Rover Mission, which will further explore Mars in search of possible signs of ancient life.
