Sparrow BioAcoustics Appoints Two Scientists to Lead AI Research and Clinical Trials

The additions to Sparrow’s team come as Sparrow makes Stethophone™ available to medical professionals in the U.S.

ST. JOHN’S, Newfoundland--()--Sparrow BioAcoustics, the company making it possible to capture heart and lung symptoms anywhere for review by medical personnel, today announced the addition of two prominent scientists to its leadership team. These promotions will accelerate the team’s work in developing Stethophone’s capabilities and making it available for people whenever they need to capture symptoms.

  • Yulia Chaikin, Ph.D., PMP, is appointed Head of Clinical Trials. Dr. Chaikin began at Sparrow BioAcoustics two years ago, most recently serving as Head of Clinical Affairs and Head of QR/RA.
  • Nick Pogrebnyakov, Ph.D., joins Sparrow as Head of AI and Data Science.

“Yulia and Nick bring important skills to Sparrow as we work to make the Stethophone the cardiac and pulmonary monitor that is always with you,” said Mark Opauszky, CEO of Sparrow BioAcoustics. “We’re excited to have them on our growing team.”

Dr. Pogrebnyakov said, “I’m excited by Sparrow’s mission, saving lives and helping improve people’s health. We’re working to improve the quality of life with the help of AI.”

Stethophone is the world’s only Software as a Medical Device (SaaMD) app that enables a smartphone to be used as a clinical-grade stethoscope to monitor the sounds of the heart and lungs. It records these sounds, allowing them to be shared securely with care team members. Stethophone needs no add-ons to plug in, connect, or charge up. Clinical tests conducted by Sparrow concluded that Stethophone performs better than industry-standard stethoscopes in cardiac and pulmonary auscultation.

Earlier this year, Sparrow BioAcoustics received clearance from the U.S. Food and Drug Administration to make the Stethophone application available to medical professionals and emergency medical technicians.

More recently, Sparrow received approval from the State Service of Ukraine for Medicines and Drugs Control to make the Stethophone app available to medical professionals, patients, and their families.
