Brendan Lee, M.D., Chair, Department of Molecular and Human Genetics
Dr. Brendan Lee took on responsibilities as department chair in December 2014 after serving as interim chair since June 2014.
Lee, a member of the Institute of Medicine, also serves as a professor in the genetics department, as well as co-director of the Rolanette and Berdon Lawrence Bone Disease Program of Texas, a collaboration of Baylor and The University of Texas MD Anderson Cancer Center and as director of the Center for Skeletal Medicine and Biology at Baylor.
He holds the Robert and Janice McNair Endowed Chair in Molecular and Human Genetics and is the founder and director of the Skeletal Dysplasia Clinic at Texas Children’s Hospital.
Lee is an internationally recognized geneticist. His research centers on understanding how gene mutations affect skeletal development and combines laboratory studies with clinical research involving patients with skeletal problems. Another important area of research for Lee is metabolic disorders or energy regulation.
Lee and colleagues were recently awarded two large NIH grants which Lee will serve as principal investigator. They include a $7.3 million, four-year grant on a study at Baylor to join a national network of clinicians and scientists joining forces to address prolonged undiagnosed medical conditions and a $6.25 million, five-year grant to lead a multi-center initiative that will focus on understanding and providing better therapeutic options for brittle bone disorder.
As an M.D./Ph.D. student at State University of New York, Downstate Medical Center in the late 1980s, he was first to clone two genes for connective tissue diseases – Marfan syndrome and spondyloepiphyseal dysplasia. He completed both his medical and doctorate degrees at SUNY and then his pediatric residency and two genetics fellowships at Baylor.
As an educator, Lee is a mentor to medical and graduate students, and directs the Medical Research Pathway at Baylor. The pathway gives medical students who do not want to pursue a Ph.D. the chance to do research in the laboratory.
Along with genetics, he is a professor in the Program in Integrative Molecular and Biomedical Sciences, Program in Developmental Biology and Program in Translational Biology and Molecular Medicine.
Lee is the recipient of many awards and honors, and was recently named as one of the 2014 Fellows of the American Association for the Advancement of Science.
Martin Matzuk, M.D., Ph.D., Interim Chair, Department of Pathology and Immunology
Dr. Martin Matzuk, who holds the Stuart A. Wallace Chair in the Department of Pathology and Immunology, was named interim chair in March 2019. He joined the Baylor faculty in 1993 after completing his postdoctoral work at the College. He earned his undergraduate degree from the University of Chicago followed by his M.D. and Ph.D. from Washington University School of Medicine.
Matzuk’s research identifies the critical proteins and mechanisms involved in both normal and abnormal reproductive development and physiology. His lab focuses on discovering small molecules that would block sperm formation or function. His work also has uncovered important physiologic and pathophysiologic signaling pathways. This research has set the groundwork for the development of a reversible male contraceptive, and creating drugs for curing ovarian cancer and for treating muscle wasting diseases.
In addition, Matzuk is a professor of molecular and human genetics, molecular and cellular biology, and pharmacology, director of the Center for Drug Discovery, a member of the NCI-designated Dan L Duncan Comprehensive Cancer Center, director of Clinical Chemistry at Harris Health’s Ben Taub Hospital, and a member of the National Academy of Sciences. He has been awarded the distinction of Fellow in the National Academy of Inventors for his contributions to reproductive medicine and therapeutics. He is the first Baylor faculty member to be elected into the National Academy of Inventors.
Jeff Rosen, Ph.D., Interim Chair, Department of Microbiology and Molecular Virology
Dr. Jeff Rosen was named interim chair of the department on July 1, 2018. He is a professor and holds the title of Charles C. Bell Professor in the department and is a leader in the Dan L Duncan Comprehensive Cancer Center.
He received his BA from Williams College in Williamstown, Mass., and his Ph.D. from State University of New York at Buffalo. He completed his post-doctoral fellowship at Vanderbilt University School of Medicine in Nashville.
He was named a Fellow of the American Association for the Advancement of Science (AAAS) in 2015 and was awarded the American Association for Cancer Research (AACR) Distinguished Lecture in Breast Cancer Research at the San Antonio Breast Cancer Symposium in 2017.
His research interest focuses on the developmental and hormonal regulation of mammary gland gene expression and breast cancer.
Timothy Palzkill, Ph.D., Chair, Department of Pharmacology and Chemical Biology
Dr. Timothy Palzkill is a professor and chair of the Department of Pharmacology and Chemical Biology. He also serves as the academic chair for the Cullen Trust for Higher Education. Palzkill earned his undergraduate degree from Creighton University and received his Ph.D. from the University Of Iowa. He completed his post-doctoral fellowship at Stanford University.
Palzkill is interested in protein structure/function and functional genomics. Currently, his lab is focused on the following fields: Molecular basis of serine and metallo β-lactamase-mediated antibiotic resistance, development of Norovirus diagnostic tools and therapeutics, and molecular recognition in protein-protein interactions. To investigate these and other diverse projects currently underway in the lab, various tools such as phage display, ELISAs, surface plasmon resonance, peptide synthesis, protein purification, enzyme kinetics, and X-Ray crystallography are used.
Joseph Petrosino, Ph.D., Interim Chair, Department of Microbiology and Molecular Virology
Joseph Petrosino is a professor in the Department of Molecular Virology and Microbiology and is the director of the Alkek Center for Metagenomics and Microbiome Research.
He is a nationally recognized leader in metagenomics research with extensive research funding. The center is an international hub for the development and implementation of advanced technologies for the understanding of how the microbiome impacts health and disease, and for the translation of this knowledge into microbiome-based therapeutics and diagnostics.
A graduate of University of Rochester, Petrosino received a Ph.D. and advance training from Baylor.
Paul Pfaffinger, Ph.D., Interim Chair, Department of Neuroscience
Dr. Paul Pfaffinger, a professor of Neuroscience and a member of the Baylor faculty for 25 years, serves as interim chair of the department. He received his Ph.D. from the University of Washington with advanced training in Molecular Neuroscience from Columbia University. He holds secondary appointments in the Graduate Program in Quantitative and Computational Biosciences and the Molecular Physiology Department and membership in the Intellectual and Developmental Disabilities Research Center and the Center for Drug Discovery. He is the author of over 50 peer reviewed journal articles. Pfaffinger also has a long standing commitment to education, and teaches and is course director for both the Graduate School and Medical school. He has won numerous teaching awards for both didactic teaching and mentoring.
Pfaffinger’s lab focuses on understanding the regulation of ion channels and their roles in native neurons. He has made important contributions to our understanding of ion channel regulation by G-protein coupled receptors, the assembly and trafficking of ion channels, and the mechanisms by which auxiliary subunit proteins are involved in driving diverse functional expression of ion channels from a relatively small number of genes. Currently, research in his lab is focusing on understanding the roles of channel diversity in information processing as well as the biophysical mechanisms underlying ion channel regulation by small peptide modulators and the role of this regulation in the brain.
