Current Lab Members

Brian Feeley, MD

 Brian Feeley, MD is the Chief of the Sports Medicine and Shoulder Service, and is currently a Professor in Residence. Dr. Feeley performs research on common shoulder and knee problems. In the shoulder, he is studying the molecular mechanisms that are responsible for the development of muscle atrophy after rotator cuff tears. His lab studies how muscle stem cells result in changes to the muscle tissue, and how to stimulate these cells to differentiate in ways to improve muscle function. In the knee, he is evaluating techniques to use low cost motion analysis to improve lower extremity kinematics and decrease injury and re-injury risk after injuries and surgical procedures. 

Xuhui Liu, MD

Xuhui Liu, MD is a research scientist in the field of orthopedic surgery. He obtained his MD degree from Peking Union Medical College in China in 2001. After that, he moved to USA and received his postdoctoral research training in Orthopedic Biochemistry and Biomechanics in Baylor College of Medicine in Houston, Texas. Dr. Liu joined the Department of Orthopedic Surgery at UCSF in
2006 as a Research Biologist. He was promoted to Assistant Professor in 2008 and Associate Professor in 2015. Majority of his research focuses on the molecular and cellular mechanism of degenerative musculoskeletal diseases. The cellular and molecular mechanism of muscle atrophy and fatty degeneration is within his central research interests. He is also interested in the role of central and peripheral nerve system in regulating musculoskeletal pathophysiology. His work has been supported by NIH, VA and private charities. 

Obiajulu Agha

Obiajulu Agha  was born and raised in Sacramento, Calif. I attended Harvard University where I studied Human Evolutionary Biology as well as the required pre medical courses. Playing college soccer and shadowing orthopedic surgeons raised my interest in a career as an orthopedic surgeon, and my two years of experience working as a research technician in a microbiology lab at Massachusetts General Hospital after college pushed me to participate in orthopedic basic science research while at UCSF School of Medicine. I enjoy basic science/translation research because it allows me the opportunity to investigate and discover molecular and cellular mechanisms in an effort to expand scientific knowledge more generally while also pursuing the next generation of novel treatments for a variety of diseases.

Michael Davies, MD

Michael Davies, MD, is currently in the residency program at the UCSF Department of Orthopaedic Surgery. Originally from San Diego, he majored in Biology at Stanford University and graduated with distinction and departmental honors before attending medical school. In between his 3rd and 4th clinical years of medical school, he completed a yearlong fellowship in the VA Orthopaedic Translational Research Laboratory at UCSF studying the molecular mechanisms and cellular progenitors involved in rotator cuff tears. He is particularly interested in therapeutic approaches to reduce muscle atrophy, fibrosis, and fatty infiltration following rotator cuff injury with a focus on characterizing the resident muscle stem cell populations that play a role in the response to injury. He plans to continue his basic-translational research focus as a clinician-scientist in the field. In his free time, he enjoys running, hiking, and cooking. He has also played piano for more than 20 years and enjoys jamming with other musicians.

He Zhang

He Zhang is a PhD candidate in Beijing Sport University, China, majoring in exercise physiology. She has been working on the prevention and treatment of skeletal muscle atrophy induced by weightlessness. Years of research experience has given her a strong interest and passion in skeletal muscle, especially the therapeutic approaches to reduce muscle atrophy and fibrosis. She is now studying the molecular mechanisms after massive rotator cuff tears in the Department of Orthopaedic Surgery at UCSF. She hopes to expand the knowledge of stem cell populations following rotator cuff injury and seek clinically relevant treatment strategies for improving RC muscle function via stem cell transplantation.


Summer Students

The Feeley-Liu lab offers a competitive summer research program for high school, college, and medical students who would like to gain experience in sports medicine and translational stem cell research. Students are paired with senior investigators and lab personnel and are responsible for learning basic techniques in molecular and cell biology, including histologic sample preparation and analysis, gene expression (e.g RT-PCR), protein expression, and assessment of stem cell function and fate. A majority of the students who participate in the lab also gain exposure to clinical research and have the opportunity to shadow in the UCSF Sports Medicine Clinic. Many students are able to present their research at local, national, and international meetings and gain authorship on abstracts for conferences as well as scientific papers.

Khalid Al-Rayess

Khalid Al-Rayess, BA, was born and raised in San Francisco, Calif. I attended the University of California Berkeley, at which I majored in Molecular Cell Biology with an emphasis in human physiology. My first exposure to research came as an undergraduate in the Eisen Lab at Cal, where I spent my time observing the effect of temperature on the early development of Drosopihlia melanogaster. From this experience, I grew a passion for finding answers to important questions in science. I sought out other projects particularly related to the medical field. I worked for a couple years at the UCSF Spine Center, where I was exposed to many spinal injuries, especially the complications that plagued patients in regards to motion and stability. As a member of the Feeley lab, I hope to contribute to limiting the complications that patients face by developing better repair models in different muscle injuries such as torn rotator cuffs. I am driven each day to continue to make this kind of impact as a doctor in the medical field.
