Gabriel F. Perez Pagan

RIDR Intern

Gabriel F. Pérez Pagán is a second-year medical student at Universidad Central del Caribe in Puerto Rico. He completed his undergraduate studies at the University of Puerto Rico. Gabriel has a strong passion for radiology and medicine, and is currently conducting research at UCSF focused on interstitial lung disease (ILD), specifically interstitial lung abnormalities (ILA) and the clinical delays between their radiographic detection and subsequent diagnosis or management.

kang

Kang Qi, MD

Visiting Faculty

 is a dedicated thoracic surgeon specializing in minimally invasive approaches to treat lung cancer, esophageal cancer, and mediastinal tumors. With advanced training in video-assisted thoracoscopic surgery (VATS) and robotic-assisted techniques, he performs complex oncologic resections with precision and efficiency. His clinical practice emphasizes a multidisciplinary approach to advanced-stage thoracic malignancies, integrating surgery with chemotherapy, radiation, and emerging systemic therapies to optimize patient outcomes.

tician

Tician Schnitzler, MD

Post Doc

Tician Schnitzler, MD is a postdoctoral research fellow at the University of California, San Francisco (UCSF) and an assistant physician in radiology at the Cantonal Hospital Aarau in Switzerland. Dr. Schnitzler’s work focuses on artificial intelligence in thoracic imaging, particularly on the development of clinical and imaging biomarkers for early lung cancer detection in interstitial lung disease (ILD), prediction of interstitial lung abnormality (ILA) progression to idiopathic pulmonary fibrosis (IPF), and clustering of IPF phenotypes to improve outcome prediction.

brandon

Brandon Schonour, BS

Medical Student

Brandon Schonour is a 4th year medical student at the University of South Alabama in Mobile, Alabama, with a research interest in image quality optimization. His current research work focuses on identifying predictors of image degradation in respiratory-triggered pulmonary MRI at 0.55T, with the goal of improving diagnostic reliability in low-field imaging. Through this research, he aims to advance the clinical utility of low-field MRI overall.
