Dr. Aaron Schimmer officially steps into his role as President and Scientific Director of the Ontario Institute for Cancer Research (OICR) today, marking a new chapter for cancer research in the province.
Schimmer brings a wealth of scientific, clinical, strategic and operational expertise to lead OICR. An internationally recognized hematologist, blood cancer scientist and research leader, he most recently served as Director of Research at University Health Network’s (UHN) Princess Margaret Cancer Centre, where he is also a longtime clinician-scientist.
As President and Scientific Director of OICR, Schimmer will lead the Institute and deliver on OICR’s provincial mandate to accelerate cancer research in Ontario for better health and a stronger economy.
Researchers have developed realistic skin-mimicking models that could help improve the accuracy of optical medical devices and wearable sensors across a wider range of skin tones. The multilayer silicone phantoms incorporate artificial blood vessels and simulated blood flow, enabling controlled testing of technologies such as pulse oximeters. The team found that coffee more closely replicated the optical properties of skin pigmentation than commercial skin-tone pigments, producing reflectance spectra of multi-layered phantoms that better matched human skin. Imaging experiments showed that darker pigmented layers increasingly masked signals from underlying blood vessels, reflecting a known challenge for light-based health measurements. The durable phantoms may provide a valuable tool for reducing skin-tone-related bias in the development and evaluation of optical healthcare technologies.
Dr. Jeffrey Keller, Hibernia National Bank/Edward G. Schleider Endowed Chair at LSU's Pennington Biomedical Research Center, and Sara Seifert, president of Minnesota HealthSolutions, have received a new National Institutes of Health Small Business Innovation Research (SBIR) award to develop an innovative digital health platform that will help parents support teenagers with attention-deficit/hyperactivity disorder (ADHD) as they learn to drive. Teen drivers with ADHD represent one of the highest risk groups for motor vehicle crashes.
The Phase I SBIR award of $353,306, funded by the National Institute of Mental Health, supports the collaboration between Pennington Biomedical and Minnesota HealthSolutions.
