Clara Ferreira

Clara Ferreira, PhD

Dr. Ferreira graduated from the Federal University of Minas Gerais, Belo Horizonte, Brazil in 2005 and received an MS degree in Physics from the same institution in 2007. In 2013, she received her Ph.D. in biomedical physics and an M.S. in Medical Physics from East Carolina University, North Carolina. In 2016, she completed the CAMPEP accredited residency at The University of Oklahoma. Her residency experience included extensive clinical training including active participation in the clinical implementation of Proton Therapy. She became ABR board certified in May 2018. To date, Dr. Ferreira has published in prestigious journals such as Medical Physics, Brachytherapy, and Radiation Oncology. She joined the Department of Radiation Oncology at the University of Minnesota in 2016 as an assistant professor and continues to pursue active preclinical and clinical research. Her research interests include image-guided radiotherapy, small field dosimetry, film dosimetry, Monte Carlo simulation, new techniques in brachytherapy, and the development of novel medical device technology and 3D printing for use in radiation oncology.

Jessica Lawrence


Dr. Lawrence joined the College of Veterinary Medicine in 2016 as an Associate Professor of Veterinary Radiation Oncology. She regularly collaborates with colleagues in the Department of Radiation Oncology for subsequently joined the 3D Printing and Imaging Lab in 2017. She is a clinician researcher with a strong interest in comparative oncology, which aims to better understand the pathobiology, diagnosis, treatment and prevention of human and animal cancer. Dr. Lawrence is particularly interested in finding new ways to improve radiation killing of cancer cells while limiting radiation-induced injury to nearby normal tissue that may result in treatment-related complications, such as acute radiation inflammation and organ fibrosis. Prior to joining the College of Veterinary Medicine, Dr. Lawrence spent 3 years as an Assistant Professor of Medical Oncology at the University of Georgia and 3.5 years as the Head of Oncology at the Royal (Dick) School of Veterinary Studies at the University of Edinburgh.

Damien Mathew


Dr. Mathew earned his PhD In Biophysics and Computational Biology at the University of Illinois - Urbana Champaign in 2010. He worked for a few years as a healthcare industry analyst and software engineer, before going back to school to obtain an MSBS degree in medical physics at the University of Toledo in 2015. He completed his medical physics residency at the University of Minnesota, and is currently an assistant professor at the University of Minnesota Department of Radiation Oncology. His research interests in this group are in 3D printed molds for superficial brachytherapy applications.

David Sterling


David Sterling is an ABR-certified medical physicist. He earned his MS in Medical Physics from Duke University in 2008, and a BA in physics from Carleton College in 2006. He worked as a clinical medical physicist in Seattle and eastern Wisconsin before joining the University of Minnesota in 2012. He enjoys teaching residents and graduate students. His research interests include 3D printing in radiation therapy, and finding novel applications of Machine Learning for cancer therapy and treatments.

Christopher Wilke


Dr. Wilke is an assistant professor in the Department of Radiation Oncology. He earned his B.S.E. in biomedical engineering from the University of Iowa followed by a Ph.D. in biomedical engineering and M.D. both at the University of Minnesota.
