Overview
Sierra Medical Ltd. is a United Kingdom-based medical diagnostics company headquartered in Oakham, Rutland. The company operates commercially under the trading name AIRA Sciences, through which it develops and markets non-invasive cancer screening technologies. Its stated mission is to make multi-cancer screening and detection accurate, non-invasive, simple, accessible, and affordable so that people can live life fully. The company's flagship offering is AIR-DS, a clinically available test that uses a 10-second cheek swab combined with basic medical history to detect signs of lung cancer, including at Stage I. According to the company, AIR-DS is 77% accurate in finding cancer and 94% accurate in ruling it out, and is equally accurate for Stage I and Stage IV cases. The test is positioned as an alternative to current lung cancer detection methods, which the company describes as facing challenges including low compliance rates and high false positive rates due to benign nodules. The AIR-DS process involves a buccal cell swab sent to an AIRA Sciences laboratory partner, where infrared spectra are generated and processed through signal processing, quality control, and inference to produce a personalized decision support report. Sierra Medical Ltd. was founded by Dr. Liberty Foreman, who serves as Chief Innovation Officer. Foreman's motivation for founding the company stemmed from her PhD work in the clinical application of infrared spectroscopy, where she observed that a standardized technique already used in aerospace and the oil and gas industry had not been adopted into routine clinical use due to the deep specialism and complex analytics required. The leadership team also includes Dr. Scott Tackett as CEO, Robert Denton as CFO, and Josh Sephton as CTO. In June 2026, AIRA Sciences announced its launch in the United States, expanding the company's commercial footprint beyond the United Kingdom. The company is privately held and is registered at Ketton Suite, The King Centre, Main Road, Barleythorpe, Rutland, LE15 7WD.
History
Sierra Medical Ltd. is a United Kingdom-based medical diagnostics company registered in Oakham, Rutland. The company operates under the trading name AIRA Sciences. Its founding is closely tied to the work of Dr. Liberty Foreman, who pursued a PhD in the clinical application of infrared (IR) spectroscopy. During her doctoral research, Foreman observed that IR spectroscopy — a standardized technique already widely used in aerospace and the oil and gas industry — had not been adopted into routine clinical use. She attributed this gap to the deep specialism required to bring together physics, biology, descriptive statistics, artificial intelligence, and medicine, as well as the bespoke and complex analytics involved and the high costs that limited such technology to larger, well-funded organizations. Foreman founded Sierra Medical Ltd. with the mission of creating a generalized model to streamline laboratories in producing fast, affordable, and accurate screening tests. The company developed AIR-DS, a clinically available test that uses a 10-second cheek swab and basic medical history to detect signs of lung cancer, including at Stage I. According to the company, AIR-DS is 77% accurate in finding cancer and 94% accurate in ruling it out, and is equally accurate for Stage I and Stage IV cases. The test is designed to address challenges in current lung cancer detection, such as low compliance rates and high false positive rates due to benign nodules. The AIR-DS process involves a buccal cell swab sent to an AIRA Sciences laboratory partner, where infrared spectra are generated and processed through signal processing, quality control, and inference to produce a personalized decision support report. On June 1, 2026, AIRA Sciences announced its launch in the United States, marking the company's expansion beyond the United Kingdom. The company is privately held and headquartered at Ketton Suite, The King Centre, Main Road, Barleythorpe, Rutland, LE15 7WD. Its leadership team includes Dr. Scott Tackett as CEO, Dr. Liberty Foreman as Chief Innovation Officer and Founder, Robert Denton as CFO, and Josh Sephton as CTO.
