People

Adam Wang, PhD

Dr. Wang is an Assistant Professor of Radiology and (by courtesy) of Electrical Engineering at Stanford University. He completed his PhD in Electrical Engineering at Stanford on maximizing the information content of dual energy CT. He then completed a postdoctoral fellowship at Johns Hopkins University in the I-STAR Lab, developing reconstruction and registration methods for image-guided surgery. Dr. Wang then spent several years in industry as a Senior Scientist in the Applied Research division at Varian Medical Systems, working on a number of topics related to image-guided radiotherapy. Since returning to Stanford, Dr. Wang is leading a comprehensive research program in advanced x-ray and CT imaging systems and methods, applied to diagnostic imaging and image-guided interventions and therapies.

Dr. Wang enjoys spending time with his family. He also enjoys running, biking, hiking, and traveling.

Maria Jose Medrano-Hammon, PhD

Dr. Medrano-Hammon is a postdoctoral fellow in the Wang group from Tegucigalpa, Honduras. She obtained her bachelor’s degree at Harding University in Searcy, Arkansas, and her PhD in electrical engineering at Washington University in St. Louis. During her PhD work she assessed and implemented model-based image reconstruction techniques and spectral material decomposition methods in proton radiotherapy. This line of research encompassed the assessment of model-based artifact reduction techniques, development of novel experiments, and implementation of Monte Carlo simulations through clinical proton therapy planning systems and Geant4/TOPAS. At Stanford, she will focus on the development of novel image reconstruction and deep-learning techniques to optimize CT image quality and patient dose delivery for different clinical tasks.

In her spare time Maria enjoys learning about new cultures, playing violin, long-distance running, hiking, and CrossFit. 

Kian Shaker, PhD

Dr. Shaker is a Wallenberg postdoctoral fellow in the Wang group. He obtained his undergraduate and PhD degree from KTH Royal Institute of Technology in Sweden. In his PhD work, he explored non-conventional contrast mechanisms in X-ray imaging (X-ray fluorescence and phase contrast) for a variety of applications: early-stage tumor localization, mammography, and respiratory imaging. Here he developed instrumentation for proof-of-principle in vivo imaging on mice as well as computational modeling (e.g., Monte Carlo & wave-propagation methods). At Stanford he is interested in exploring intersections between clinical X-ray imaging and global health, particularly targeting the limited availability of chest radiography in many low- and middle-income countries (e.g., relevant for tuberculosis screening).

Outside research, Kian enjoys indoor climbing, cooking, learning about cultural and societal issues, and listening to experimental (mostly electronic) music.

Liyan Sun

Dr. Sun is a postdoctoral fellow in the Wang group. He obtained his PhD degree from Xiamen University in China. His main research interests were fast medical image reconstruction based on deep learning, medical image segmentation under data-limited conditions, and medical image synthesis specifically generating pseudo-healthy images during his PhD program. His research aim is focused on acquiring high-quality medical images with high time efficiency and low radiation exposure.  At Stanford, he will focus on developing acquisition and reconstruction methods for enhancing novel CT systems and applications, including photon-counting CT and time-resolved breast CT. Liyan enjoys swimming, hiking, and cooking.
