Luca Giancardo, PhD, assistant professor at UTHealth School of Biomedical Informatics, has been awarded one of six grants from Baylor College of Medicine’s Translational Research Institute for Space Health. Each recipient’s project focuses on advancing biomedical and health research in deep space.
The projects aim to develop novel solutions to some of NASA’s highest priority risks to human health and performance during deep space exploration missions.
An untreated stroke event would be destructive for an astronaut during a deep space exploration mission. Increased cerebrovascular disease risk has been documented after prolonged exposures to ionizing radiations on Earth. Astronauts on deep space missions will be exposed to galactic cosmic rays and solar particles for 30 months, which can lead to accelerated vascular injury, likely increasing their risk of stroke.
Giancardo’s project aims to develop new technological approaches to detect and differentiate various stroke types, which can be very difficult in space. On Earth, these strokes are quickly identified by CT or MRI scan. However, these brain imaging capabilities are not available in deep space, and alternative, robust means of diagnosing and classifying strokes are needed. Giancardo noted that “while attending a seminar, I learned that strokes were one of the issues astronauts face during deep space missions so I decided to further explore this matter.”
“Our ultimate objective is to develop a machine learning-based algorithm to detect ongoing acute stroke and the stroke type using noninvasive retinal imaging devices, which will be available in deep space missions,” Giancardo said.
The project is interdisciplinary in nature. Giancardo is serving as the principal investigator for the team project, along with two co-investigators: Sunil Sheth, MD, vascular and interventional neurologist and assistant professor at McGovern Medical School at UTHealth, and Roomasa Channa, MD, ophthalmologist and assistant professor at Baylor College of Medicine. Channa, who is familiar with Giancardo’s previous algorithm-centric research as it relates to developing retina image analysis, introduced him to the grant opportunity.
Giancardo noted that “while attending a seminar, I learned that strokes were one of the issues astronauts face during deep space missions so I decided to further explore this matter.”
This research team is uniquely positioned to pursue this type of research. Beyond expertise in machine learning algorithm development for stroke brain imaging and retina imaging, the team has the support of the Institute for Stroke and Cerebrovascular Diseases at UTHealth. The institute is at the forefront of stroke research and has access to data from a large population. Furthermore, it was one of the first stroke centers established in the world and the first stroke center established in Houston. Giancardo is a faculty member in the School of Biomedical Informatics’ Center for Precision Health.
“If successful, we would be able to create a system that will not only impact the deep space mission, but it will be extremely useful for stroke management when brain imaging is not available,” said Giancardo.
The grant is worth just under $800,000 and includes additional support from UTHealth. Giancardo received two years of funding support.
