Quickly evolving know-how might sooner or later mean you can skip an invasive medical process in favor of sending your labs to the physician by importing a screenshot out of your cellphone.
Due to pioneering analysis, that is the way forward for customized medication and illness diagnostics, in line with Regents’ Professor of Physics Unil Perera.
“In 10 to 15 years, I hope to see this technology in your smartphone, and in your everyday life,” Perera says. “Imagine being able to take your own health readings from the comfort of your home. The potential for early detection and personalized medicine is enormous.”
For Perera, the fact of non-invasive, accessible medical diagnostics is advancing due to progressive know-how often called ATR-FTIR spectroscopy—quick for attenuated complete reflectance-Fourier remodel infrared. It is a technique of investigating the molecular composition of supplies utilizing infrared mild to disclose tiny particulars often hidden from view. By making use of it to medical diagnostics, illnesses like melanoma will be detected early from an infrared scan.
Perera’s analysis strategies have already proven the potential for advancing diagnostics for a number of circumstances, and his work has garnered patents for detection of melanoma, lymphoma, colitis, and different sorts of cell activation.
The subsequent step? Tracing illness development. His newest analysis focuses on exactly gauging how a illness advances over the course of days and dealing to outline benchmarks which might then be utilized in real-world, scientific settings. This sort of diagnostic might ultimately be used to determine, for instance, the remedy efficacy of a selected drug, giving the doctor the prospect to reply as shortly as wanted.

“The beauty of ATR-FTIR spectroscopy lies in its ability to provide detailed molecular data and identify disease progression without needing invasive procedures,” Perera explains. “The hope is to develop technology that can be embedded in everyday devices, allowing individuals to monitor their health without stepping into a clinic.”
With this strategy, he believes the developments might revolutionize the way in which we diagnose all the things from the widespread chilly to colon most cancers.
Perera additionally has a deep ardour for instructing and mentoring the subsequent technology of scientists. He has been inspiring college students at Georgia State for greater than 30 years along with his fundamental instructing philosophy of “Don’t be afraid of physics.” Perera’s lab is at the moment house to 5 graduate college students, every contributing to the collaborative analysis underway.
“Physics is all about curiosity,” he says. “It’s about asking, ‘Why and How?’ and then pushing boundaries to find the answers.”
Perera’s instructing philosophy is rooted in creating an surroundings the place college students really feel empowered to ask large questions and discover potentialities with out the worry of failure. “In science, failure isn’t the end. It’s often the beginning of something new,” he says.
As well as, Perera’s work exemplifies the multidisciplinary nature of recent scientific discovery. To unravel advanced issues, Perera brings collectively specialists from quite a lot of fields, together with engineering, chemistry, biology and arithmetic—in addition to physics. He’s a fellow with the engineering and know-how society IEEE, the American Bodily Society (APS) and the Society of Photograph-Optical Instrumentation Engineers (SPIE) and he encourages this multifaceted strategy along with his college students.
“Studying physics opens doors to more than just one field. It’s the key to data science, semiconductors and even the companies shaping the future like Nvidia,” Perera says. “With curiosity and a willingness to ask questions, physics can take you anywhere, from computer programming to cutting-edge engineering. It’s not just about what you learn, but what you can create.”
