Lab Members

Ting Liu, MD, PhD
Postdoctoral Scientist

Ting Liu, MD, PhD, received her medical degree and doctorate in radiology from China Medical University. Liu completed her postdoctoral research training in cardiac CT MRI PET program in Massachusetts General Hospital, Harvard Medical School between 2012-14. As a radiologist with 10 years' experience in cardiac imaging, she has been collaborating with Debiao Li, PhD, since 2015 and joined the Dr. Dharmakumar's laboratory as a visiting postdoctoral scientist in October 2018. Her current research interest is in the clinical application of myocardium infarction using novel magnetic resonance imaging modality.

Yinyin Chen, MD, PhD
Postdoctoral Scientist

Yinyin Chen, PhD, received both her bachelor’s and master’s degrees from Soochow University in China. She earned her doctorate in imaging and nuclear medicine at Shanghai Fudan University in June 2016. Chen joined the Dharmakumar Lab as a visiting postdoctoral scientist in April 2019. Her current research interests are in diagnostics and implications of intramyocardial hemorrhage based on novel non-contrast-enhanced magnetic resonance techniques.

Xingmin (Diane) Guan, MS
Graduate Student

Xingmin (Diane) Guan received both her bachelor's and master's degrees in materials science and engineering at Shanghai Jiao Tong University. She is currently a doctoral student at UCLA majoring in bioengineering. Guan joined the Dharmakumar Laboratory in 2016. Her research interest is in developing novel MRI-based methods to quantify iron and fat in the heart with a focus on novel data acquisition methods, image processing and validation in animal models of myocardial infarction. Her goal is to translate her research findings to human subjects with prior myocardial infarctions.

Project Scientist

Hsin-Jung (Randy) Yang, PhD, earned his doctorate in bioengineering from UCLA in August, 2016. He earned his master's degree at Northwestern University in electrical engineering and joined the Dharmakumar Laboratory in Cardiac MRI in 2011 and the Han Lab in 2016. His current research interests are novel MRI technologies and their applications.

Xinheng (James) Zhang, MS
Graduate Student

Xinheng (James) Zhang earned his bachelor’s degree in basic medical sciences at Zhejiang University and master’s degree in biomedical imaging at University of California, San Francisco. He started his postdoctoral studies in bioengineering at UCLA in 2017. In the same year, he joined the Dharmakumar Lab. His current research interests are novel techniques in MR image post-processing and pulse sequence programming.

Eric Johnson
Graduate Student

Eric Johnson earned his bachelor’s degree in bioengineering from the University of California, Berkeley in December 2011. After working as a biomedical engineer for a startup medical device company in San Diego, he came to UCLA as a PhD student in 2015. He joined the Dharmakumar Lab in March 2017 to work on cardiac MRI. His research interests are in the novel diagnostics and therapeutics applied to heart disease and myocardial infarction.

Anand Nair, PhD
Project Scientist

Anand Nair, PhD, received his doctorate in biomedical sciences from Louisiana State University in 2015. His doctoral work focused on the mechanisms by which Toll-like receptor-4 mediates the progression of acute and chronic renal disorders. Nair completed his postdoctoral training in cardiovascular pharmacology from the University of Iowa, concentrating his research on mechanisms of endothelial dysfunction in cardiovascular diseases. With a strong background in cell and molecular biology, Nair joined the Dharmakumar Laboratory in the Cedars-Sinai Biomedical Imaging Research Institute as a project scientist. He plans to expand his knowledge of cardiovascular pathophysiology by focusing on the molecular mechanisms driving hemorrhagic myocardial infarctions.

Richard Tang, MD
Senior Research Associate

Richard Tang, MD, earned his medical degree from Shanghai Medical College of Fudan University in China. After completing his resident training, Tang became an attending ophthalmologist in Shanghai Eye and ENT Hospital and completed his postdoctorate training in National Institutes of Health/National Eye Institute. Tang began working with Debiao Li, PhD, in 2000 and Rohan Dharmakumar, PhD, in 2005, in the field of myocardial ischemia and infarction. Tang also has many years of experience working with large animal cardiovascular research models, animal cardiac surgery and clinic trials in both human and animal models.

Khalid Youssef, PhD
Project Scientist

Khalid Youssef, PhD, received his doctorate in biomedical engineering from UCLA in 2015. He conducted his postdoctoral research at the Bouchard’s lab, where he developed new deep learning algorithms targeting problems that are intractable with existing deep learning methods. He joined the Dharmakumar Lab and the Sharif Lab at Cedars-Sinai in 2019. His current research involves the application of his deep learning methods and expertise to a variety of cardiac magnetic resonance imaging problems.

Andrew Howarth MD, PhD
Visiting Professor

Dr. Howarth is a Cardiologist and Cardiovascular Imaging Specialist currently on Sabbatical from the University of Calgary in Canada. Dr. Howarth obtained his PhD in Anatomy and Cell Biology from the University of Alberta and his MD from the University of British Columbia. He is a practicing clinician with research interests in Cardiac MR. While visiting Cedars Sinai, Dr. Howarth is collaborating on projects focused on the pathophysiology of acute MI and the role of intramyocardial hemorrhage. He also spends time with the clinical service in the CT angiography group.
