Dr. Melby joined UTMB in 2010 as Professor of Internal Medicine in the Division of Infectious Diseases and Director of the UTMB Center for Tropical Diseases. His research program is related to the immunopathogenesis of parasitic diseases, with a particular focus on leishmaniasis. His laboratory has been involved in vaccine development, studies to determine immunopathological mechanisms of disease, studies to define the impact of malnutrition on innate immunity and visceral leishmaniasis, and drug discovery. His interest in tropical diseases and the neglected diseases of resource-poor developing countries started thirty years ago when he first worked overseas in a hospital laboratory in rural Egypt. He subsequently returned to the U.S. to attend medical school at the University of Colorado and then went on to complete my residency in Internal Medicine at the University of Missouri, a research fellowship in the Laboratory of Parasitic Diseases at the National Institutes of Health, and a clinical infectious diseases fellowship at the University of Texas Health Science Center, San Antonio. He is active in the clinical practice of infectious diseases and in the teaching of medical and graduate students, as well as clinical residents and fellows.

Dr. Khadija Tayabali
Dr. Tayabali's T32 Experience
- What inspired you to join the T32 program?
I was drawn to the T32 program for its unique ability to combine a mentored research career with the flexibility to explore a research topic that truly piques my interest. The opportunity to build a project from the ground up, while also gaining hands-on experience in clinical service, made the program particularly appealing. The two-year structure allows for the perfect balance between research and clinical exposure, offering the best of both worlds in an environment that fosters growth and development.
- How has the program supported your research and career development?
The T32 program has been instrumental in shaping my career path. Dr. Melby has played a pivotal role in guiding me, offering valuable mentorship by helping me identify key mentors and shaping ideas into viable research projects. His insights, drawn from years of experience, have been crucial in understanding how to make a pilot project successful. The program also offers a variety of training opportunities, such as tropical medicine courses, grant writing workshops, and specialized biosafety lab training, which have enhanced both my research skills and my overall career development.
- What do you consider the greatest benefit of being a T32 fellow?
The greatest benefit of being a T32 fellow is the ability to seamlessly integrate clinical practice with research in a respected institution like UTMB. This unique combination has allowed me to expand my clinical expertise while also growing as a researcher. Being part of a program that values both aspects of my career has been incredibly rewarding and essential for my professional growth.
Biography
Dr. Khadija Tayabali is a dedicated physician and researcher with a passion for global health, infectious diseases, and antimicrobial resistance. Originally from Kenya, she earned her medical degree at the University of Nairobi, where she began her career working in Bungoma District Hospital. There, she focused on the care of patients with HIV/AIDS and tuberculosis, collaborating with the PEPFAR initiative to address dual challenge of these co-infections.
After relocating to the United States in 2012, Dr. Tayabali completed her Internal Medicine residency, followed by Chief Residency, at Greater Baltimore Medical Center in Baltimore, Maryland. She then pursued a fellowship in Infectious Diseases at the University of Maryland Medical Center, graduating in August 2024.
In October 2024, Dr. Tayabali joined the University of Texas Medical Branch as a T32 Research Fellow. Her research interest are focused on antimicrobial resistance and its profound impact on global health and addressing global health disparities in a resource rich hospital in Kenya

Dr. Francisco Guerra, Jr
Dr. Guerra's T32 Experience
There are truly very few places in the USA where physicians and scientists collaborate to detect emerging infections arising from anywhere in the world using a One Health approach, are able to study such diseases in secure and highly advanced labs, and can then create new technologies ranging from diagnostics to therapeutics (such as monoclonal antibodies and antiviral drugs). UTMB and the Galveston National Laboratory situated on the UTMB campus is one place where such pivotal research takes place. For physician scientists looking to start their careers, this is an ideal place to start, learn, and collaborate. For example, a typical day of clinic (seeing patients with AIDS, MDR TB, or murine Typhus) could be followed by a lecture from a researcher about their work surveilling an outbreak of Ebola or Oropouche viruses.
Biography
Dr. Francisco Guerra, Jr. is committed to bridging biomedical research with the practice of medicine, bringing scientific advances closer to practical medical applications that address important public health priorities. He draws on a broad and interdisciplinary background in drug discovery, bioengineering, biophysics, computational biology, physical chemistry, structural biology, spectroscopy, computational modeling, enzyme kinetics, thermodynamics, quantum mechanics, molecular and cellular biology, organic synthesis, global health, and the social determinants of health to develop pioneering therapeutics against emerging infectious diseases.
Dr. Guerra has collaborated with researchers using a One Health approach to detect zoonotic spillover events. His recent work has focused on developing antimalarials with novel mechanisms of action against proven essential Plasmodium spp. targets—an increasingly urgent need as artemisinin resistance spreads throughout Southeast Asia.
At the University of Texas Medical Branch (UTMB), Dr. Guerra has redirected his research to target respiratory viruses, recognizing their universal impact and the profound societal disruptions they can cause, as demonstrated by the COVID-19 pandemic. His current research focuses on two main areas: (1) developing therapeutics for Influenza and other respiratory viruses, and (2) detecting emerging respiratory virus spillover and spillback events—particularly Influenza—through a One Health approach.
