Georgia Tourassi

thumb Georgia Tourassi Georgia "Gina" D. Tourassi is a Greek-American physicist, biomedical engineer, professor of radiology, expert on computing in biomedicine, and director of the National Center for Computational Sciences at the Oak Ridge National Laboratory (ORNL). Born and educated at the undergraduate level in Greece, she holds 13 U.S. patents. Among her many honors, she was elected in 2017 a Fellow of the the International Society for Optics and Photonics (SPIE) and in 2020 a Fellow of the American Association for the Advancement of Science (AAAS). Quotes Unquestionably, the Radiology radiologists approach the diagnostic task with a level of intelligence, flexibility, and common sense that is difficult to duplicate with a computer. Thus far, research findings have demonstrated only that computers are the best savants when it comes to executing mathematically rigorous steps toward the solution of narrowly defined problems.Nonetheless, the radiologist's approach is not devoid of limitations. There are well-documented errors and variations in the human interpretation of Medical imaging clinical images ... Some study findings even indicate that the same errors are being made now, as they were in earlier decades ...

The United States Department of Energy Department of Energy’s Leadership Computing Facilities have a long history of enabling researchers to accelerate Discovery (observation)#Science scientific discovery and deliver practical breakthroughs for some of the most computationally challenging problems. These research and development advances happen across many disciplines such as materials science, earth science, nuclear science, astrophysics, biology, and engineering to name a few. In addition, supercomputing has proven to be an effective ally to our society by helping us address critical and pressing challenges, such as climate change, State of emergency national emergencies, and public health. For instance, supercomputers help researchers develop personalized medical treatments as well as better predict and manage the effects of natural disasters such as floods and earthquakes through the use of advanced computer simulations. ... These discoveries help shape our understanding of the universe, bolster US economic competitiveness, and contribute to a better future. ...

And both our laboratories are very proud to have delivered on that vision with these two systems that are dedicated to open science. We are already seeing how exascale computing is driving innovation and breakthroughs in many scientific domains, including medicine, from drug discovery all the way to clinical care. And this is a crucial milestone for science and technology because, now, we can tackle challenges that previously we could not. We can tackle them faster. We can analyze large scales of data with extreme efficiency. We can do simulations of very complex systems.
