Lab Members

Juan M. Melero-Martin, Ph.D.

Principal Investigator
Associate Professor of Surgery

Dr. Melero-Martin holds a degree in Chemical Engineering from the University of Seville, Spain, and completed his Ph.D. in Tissue Engineering at the University of Birmingham, UK. Following a postdoctoral fellowship in the Vascular Biology Program at Boston Children’s Hospital, he was appointed to the Department of Cardiac Surgery at the same institution in 2008. In 2018, Dr. Melero-Martin was honored with the inaugural Chair in Cardiac Surgery, named after John Mayer, Jr., MD.

Umji Lee, Ph.D.

Postdoctoral Research Fellow

Dr. Umji Lee earned her B.Eng from Seoul National University of Science and Technology and obtained her M.S in life sciences at Swiss Federal Institute of Technology in Lausanne (EPFL) in 2016. After she earned her Ph.D. at EPFL under the supervision of Dr. Jerome Feige and Dr. Benjamin Cosgrove at Cornell University, she joined the Melero-Martin Lab as a postdoctoral fellow in 2021. Her current research focuses on developing effective ex-vivo gene therapy for hemophilia patients with a tissue engineering approach.

Liyan Gong, Ph.D.

Postdoctoral Research Fellow

Dr. Liyan Gong earned her B.S. degree in Biotechnology from Jilin University and obtained her Ph.D. degree in Biochemistry and Molecular Biology from the Center for Excellence in Molecular Cell Sciences, Chinese Academy of Sciences, China. She then conducted a short postdoctoral training at Tongji University to study important signaling transducers’ basic regulatory mechanisms and post-translational modifications. In 2022, she joined the Melero-Martin Lab as a postdoctoral fellow. She is currently involved in several projects in vascular biology and regenerative medicine.

Xiang (Grace) Li, Ph.D.

Postdoctoral Research Fellow

Dr. Xiang (Grace) Li earned her B.S. in China Agricultural University and M.S. in The Ohio State University in Animal Sciences. She then worked on stem cell therapy for diabetes in Dr. Jon Odorico’s lab at the University of Wisconsin-Madison. In 2021, Grace obtained her Ph.D. degree with studies on cellular senescence, aging, and liver diseases, mentored by Dr. Scott Lowe in Memorial Sloan Kettering Cancer Center/Weill Cornell Graduate School of Medical Sciences. She joined the Melero-Martin Lab in 2022 and focuses on the studies of vascular biology in bone regeneration and tissue engineering.

Yonglin Zhu, Ph.D.

Postdoctoral Research Fellow

Dr. Yonglin Zhu earned his B.S. in Biology and Pharmacology from Jilin University, China. He then joined Dr. Jie Na’s lab at the School of Medicine, Tsinghua University, to study the genetic and epigenetic regulation of vascular cell differentiation from human pluripotent stem cells (hPSCs). After he obtained his Ph.D. in Cell Biology, Dr. Zhu joined the Melero-Martin Lab in 2022 as a postdoctoral fellow and continues to pursue his interest in vascular biology and regenerative medicine using hPSCs.

Daniel Tremmel, Ph.D.

Postdoctoral Research Fellow

Dr. Daniel Tremmel received his B.S. in Chemistry, Biochemistry, and Genetics from the University of Wisconsin (UW) and worked for several years as a research assistant in the Bacteriology and Genetics departments at UW. Dan continued on to do his graduate studies at UW in the Department of Surgery, studying the extracellular matrix of pancreatic islets under the supervision of Dr. Jon Odorico and Dr. Sara Sackett. He received his Ph.D. in Cellular and Molecular Biology in 2022, and joined the Melero-Martin lab shortly afterward as a postdoctoral research fellow working to engineer the vasculature of stem cell-derived islets.
