Anthony G. Christodoulou, PhD
Research Scientist

Anthony G. Christodoulou, PhD, earned his doctorate in electrical and computer engineering from the University of Illinois at Urbana-Champaign before joining the Cedars-Sinai Biomedical Imaging Research Institute in 2015. Christodoulou's primary research interests are in multidimensional quantitative MRI methods and techniques, particularly the development of MR multitasking.

Zixin Deng, PhD
Postdoctoral Scientist

Zixin Deng, PhD, received her bachelor of science in biomedical engineering from the University of California, Irvine, with a specialization in biophotonics. In November 2017, she completed her doctoral studies in bioengineering at UCLA under the supervision of Debiao Li, PhD. Her current research interest is in the development of novel MRI techniques. She has been working specifically in applications such as cardiovascular disease and radiotherapy planning for abdominal cancer. She began as a graduate student and is remaining in the Li Laboratory as a postdoctoral scientist continuing her work on developing novel MRI techniques.

David Gultekin, PhD
Project Scientist

David Gultekin, PhD, joined Cedars-Sinai Medical Center from Memorial Sloan-Kettering Cancer Center and Cornell Medical College, where he had joint appointments as assistant professor. He provided a broad range of physics and engineering expertise for cancer imaging and participated in multi-institutional clinical trials for the assessment of response to radiation, chemical cytotoxic and targeted therapies such as monoclonal antibodies and anti-angiogenic therapies. He developed methods and algorithms for processing large radiological datasets to enhance clinical practice and research. He investigated MRI techniques to measure mass and energy transport processes with high spatial and temporal resolutions and developed methods for measuring thermal diffusivity, thermal conductivity, heat transfer coefficients, specific heat, specific absorption rate, thermal power and heat of reaction in substances noninvasively. He received a BS degree at ITU-Istanbul, an MS degree at Stevens, completed a graduate program at MIT and then received MS, MPhil and PhD degrees at Yale University. He held postdoctoral and fellowship positions at Duke, Caltech and Johns Hopkins. Dr. Gultekin joined Dr. Debiao Li to advance cancer imaging programs.

Touseef Ahmad Qureshi, PhD
Project Scientist

Touseef Ahmad Qureshi, PhD, earned his doctorate in medical image computing from the University of Lincoln, England, in 2016. Afterward, he worked as postdoctoral research fellow at the Department of Medical Physics and the Department of Epidemiology and Biostatistics in Memorial Sloan Kettering Cancer Center in New York. In the Li Laboratory, Qureshi works on multiple projects developing cancer detection and risk prediction models, as well as teaching activities for students of BIRI and UCLA. Qureshi has extensive research experience in retinal image computing and analysis. He has performed studies for quantifying retinal vascular behavior with association to several diseases including diabetic retinopathy, macular degeneration and cardiovascular complications. His main focus is on analyzing MR/CT images and genetic data for early detection and prediction of breast cancer and pancreatic cancer. Qureshi has technical expertise in machine learning, deep learning, deep data analysis, Bayesian probability and graph based approaches to solve low-level vision problems.
