Transplant Research Group
What we do:
Fundamental and translational research to learn how cells/tissues/organs maintain their unique and homeostatic gene expression signatures, and what we can do to return them to this state during degenerative or disease
conditions.
How we do it:
We use genomic, proteomic, molecular genetics, cell
biological, and biochemical approaches to learn about these systems, and have a particular interest in how regulation of RNA processing fits into the picture.
Active Projects: - Preventing and reversing liver (and other types of) fibrosis
- Determining how RNA binding proteins (RBPs) influence early cell fate decisions
- Testing how alternative splicing leads to changes in transcript abundance and localization
- Exploring embryonic-, amniotic-, and adult stem cell-based regenerative medicine options

Sam Fagg PhD, MS
John L. Hearn Endowed University Chair of Transplant Surgery
Faculty Member of Graduate School of Biomedical Services, Human Pathophysiology and Translational Medicine (HPTM)
My true passion in research lies at the intersection of discovery and “the next step.” When we make one significant finding the immediately emerging question is “what is the next step?” This can be as challenging as making
a discovery, but often is more important. I also thoroughly enjoy being engaged in training the next generation of scientists and physician-scientists, and so I like to discuss science with the folks in my lab and elsewhere. I am especially interested
in how competition between RBPs and regulatory or substrate RNAs influences the overall gene expression process and as a result, cell fate. I also enjoy spending time with my family, surfing, fishing, and traveling.
I got my Bachelor of Science degree at Lees McRae College in Banner Elk NC, then my Master’s at East Carolina University with Mary Farwell, unofficial embryonic stem cell and molecular genetics training at Cedars Sinai Medical Center in Los Angeles
CA with Seigo Hatada and Jeff Fair, and did my PhD and a brief postdoc with Manny Ares Jr at UC-Santa Cruz in Santa Cruz, CA.

Mike Kueht, MD (Transplant Surgeon)
As an active transplant surgeon and scientist, my research revolves around important factors contributing to pre- and post-transplant outcomes. Our studies range from epidemiological-scale projects
to ex-vivo studies of the human immune system. Importantly, with our collaborators, we have laid the groundwork for measuring phenomena within the transplant operation as a tool to help manage the post-transplant setting. We are focused on exploring
the interplay between donor and recipient factors, organ preservation, operative kinetics, and immunosuppression and its effects on graft function and recipient health.
Jose Abril, MS4
I am a second-year medical student with a deep interest in leveraging computational approaches to address complex biological challenges. My research is focused on developing and implementing computational solutions to understand and tackle various aspects of human health and disease. Currently, I am part of Dr. Sam Fagg's group, where I aim to contribute to the lab's projects through bioinformatic approaches, data pipelines, and dataset analyses.
Before joining UTMB, I completed my undergraduate studies in Biomedical Sciences at Sam Houston State University. Under the guidance of Dr. James Harper and Dr. Anne Gaillard, I gained a solid foundation in molecular biology and physiology. As an avid technology enthusiast, I am always excited to incorporate the latest technological advances into my medical training and research endeavors. I am grateful for the opportunity to blend my dual passions for biology and technology under Dr. Fagg's mentorship.
My ultimate goal is to become a physician who can seamlessly integrate the fast-paced technological advances into medical research and clinical practice. I aspire to instill in my two young children a love for medicine, research, and technology, nurturing a future generation that shares this enthusiasm.
Brian Amburn, MD/ PhD
"I have always been interested in the improvement of human medicine and the expansion of our reach. I’m a fourth-year MD-PhD student (second-year graduate student) at UTMB in Dr. Sam Fagg’s lab, currently studying how non-coding RNAs can interfere with RNA processing exacerbating disease states in the heart. Not only may this identify a new drug target for heart disease but may illuminate novel mechanisms through which non-coding RNAs disrupt RNA processing machinery.
As I grow in my training my goals develop and currently have landed on a long-time dream of mine. To medically treat and support people in the most extreme situations possible, particularly spaceflight. The training under Dr. Fagg will afford me the knowledge and skills necessary to perform research relevant to what happens in the extremes, in disease and space.
Maxsam Donta, MS
I am an MD-PhD student in Dr. Fagg’s lab. My work integrates computational analyses with mechanistic experiments to identify RNA-binding proteins and splicing programs that regulate hepatic stellate cell activation and liver fibrosis. This may identify therapeutic candidates to treat liver disease. Before UTMB, I completed my B.S. in chemical engineering at Iowa State University, and my M.S. in biomedical sciences at MD Anderson Cancer Center/UTHealth Houston. My long-term goal as a physician scientist is to bridge innovative research with patient care.
Naiyou Liu, PhD (Project Scientist)
Naiyou obtained his PhD from the Chinese Academy of Sciences in 2008. In his current role as Project Research Manager, he is interested in how RBPs and alternative splicing can influence stem cell
biology including plasticity between cell fates/lineages. He also has interests in determining how specific RBPs function mechanistically and is working to understand how splicing can influence additional steps in the RNA processing cascade. Naiyou
also supports other projects in the lab including those studying applied and fundamental regenerative medicine.
Marcus Luciano, BS
My research focuses on the RNA binding protein Quaking and how its specific isoform biogenesis is regulated by alternative splicing. I completed my Bachelor of Science degree in Forensic Science from Middle Tennessee State University and intend to pursue an advanced degree in the future.
Antwine W. McFarland Jr, PhD, MS
My current research is focused on the autoregulation of the RNA binding protein Quaking. We hope to understand the complex relationship between the elements that impact Quaking isoform biogenesis regulation in different cell types. My interests are in alternative splicing, cell and molecular biology, and regenerative medicine. My extracurricular interests are in powerlifting, fishing, and cooking.
I earned my Bachelor of Science degrees in Chemistry and Biological Sciences from Louisiana Tech University. I then worked in industry before returning to earn Master’s in Molecular Science and Nanotechnology, and PhD in Molecular Science and Nanotechnology with David Mills from Louisiana Tech University. I held a postdoc position with Liisa Kuhn at UConn Health.
Emmanuel Nyong, MD/ PhD
I'm currently a first-year Ph.D. student in the Human Pathophysiology and Translational Medicine program at the University of Texas Medical Branch (UTMB), where I'm part of Dr. Sam Fag's research group. My research focuses on understanding how posttranscriptional regulation of gene expression by RNA binding proteins (RBPs) influences early cell fate decisions. I aim to explore the role of the RBPs CELF2 and QKI in developmentally regulated splicing patterns using various molecular, cell biology, and biochemical approaches. Before embarking on my PhD journey at UTMB, I completed my undergraduate studies at the University of Texas at San Antonio, engaging in research under Dr. Mark Eppinger.
With a career vision as a physician-scientist, I am dedicated to forging a path that connects fundamental scientific research with its practical clinical applications.
