Dr. Land received his Ph.D. in microbiology from the Tulane University Medical Center in New Orleans, Louisiana in 1973. He then completed an NIH-sponsored research fellowship in microbiology at the Duke University Medical Center in Durham, North Carolina before joining the faculty at the Wadley Institutes of Molecular Medicine (now Carter Blood Care) in Dallas, Texas for five years, followed by the University of Cincinnati Medical Center as an Assistant Professor of Pathology. Dr. Land later held the appointment of Clinical Professor of Pathology at The University of Texas Southwestern Medical Center and Director of Microbiology and Immunology at Methodist Medical Center in Dallas, Texas before becoming a full professor in the Department of Pathology at the Baylor College of Medicine in Houston in 2002. Dr. Land has held numerous leadership positions throughout his career, and is actively involved in quality assurance and the standardization of histocompatibility laboratory procedures and practices. He is an active laboratory inspector, serving on the American Society for Histocompatibility and Immunogenetics (ASHI) Accreditation Review Board as commissioner (2 terms), co-chair, and program director. He has also served as a co-editor of the ASHI laboratory manual and as president of ASHI. Dr. Land received his faculty appointment at the Weill Cornell Medical College in 2005.

Dr. Land is both an immunologist and microbiologist with special interests in the human major histocompatibility antigens and alleles, transplant Immunology, opportunistic Infections, mycobacteria, medical mycology, and the actinomycetes. His research interests are both clinical and translational in nature and include developing rapid methods for human histocompatibility crossmatching, transplantation of highly sensitized patients, and direct rapid phenotypic or molecular methods for species identification of mycobacteria and fungi and for human histocompatibility typing. These projects utilize SSP-PCR, RT-PCR, DNA sequencing, flow cytometry, and solid phase multi-channel arrays.
