Associate Professor of Public Health Policy and Management

Biography: 

Michael Halpern is Associate Professor and Section Chair of Public Health Policy and Management at the Mel and Enid Zuckerman College of Public Health, University of Arizona.  His work focuses on health services and outcomes research, including evaluating patterns of medical care, quality of care, comparative effectiveness and cost-effectiveness, access to care, and disparities.  Research by Dr. Halpern includes evaluations of patient characteristics, risk factors, medical treatments, and health outcomes using large medical claims data bases and national health care surveys; assessments of government policies affecting receipt of health care services; systematic reviews, meta-analyses, and guideline development; modeling the health and economic impacts of medical care interventions; development and analysis of workplace-based smoking cessation; assessments of patient symptoms, satisfaction, and quality of life; and examinations of factors influencing decision making by physicians and patients.  Dr. Halpern received his M.D. and Ph.D. in the Medical Scientist Training Program and M.P.H. in epidemiology at The University of Michigan.  He serves on the Health Disparities Committee and Cancer Survivorship Committee of the American Society of Clinical Oncology and on the Scientific Review Committee of the American College of Preventive Medicine, and is the Section Editor for Health Disparities of the journal Cancer.

Biography: 

Joe G.N. "Skip" Garcia, MD, is the University of Arizona senior vice president for health sciences, an endowed UA professor of medicine and an elected member of the Institute of Medicine of the National Academies. An internationally noted physician-scientist, health administrator, scholar and educator, Dr. Garcia also is a leading authority on the genetic basis of lung disease and the prevention and treatment of inflammatory lung injury.

A key member of the UA’s senior executive team, Dr. Garcia provides academic leadership for the Arizona Health Sciences Center (AHSC) colleges: the UA College of Medicine – Tucson, the UA College of Medicine – Phoenix, the UA College of Pharmacy, the UA College of Nursing and the UA Mel and Enid Zuckerman College of Public Health. He also has direct leadership oversight of the UA Cancer Center.

Dr. Garcia also serves as the program director and principal investigator for the Arizona Pride-25 Advanced Health Disparities Training Program in Heart, Lung, Blood and Sleep Conditions grant, designed to assist AHSC junior faculty members and transition postdoctoral fellows by offering mentoring and leadership development activities, advanced disparities research training and project-based experiences.

Before joining the UA, Dr. Garcia served as vice president for health affairs at the University of Illinois and as the Earl M. Bane Professor of Medicine, Pharmacology and Bioengineering at the University of Illinois at Chicago (UIC).  As vice president for health affairs, Dr. Garcia oversaw the University of Illinois Hospital & Health Sciences System, a $1.2 billion health sciences and clinical enterprise. He also provided oversight of the University of Illinois Hospital and the University’s federally qualified community health centers.

His prior leadership positions include director of the Division of Pulmonary and Critical Care Medicine at Johns Hopkins University (1998-2005), chairman of the Department of Medicine at the University of Chicago (2005-2009), and vice chancellor for research at UIC (2010-2012).

Dr. Garcia is internationally recognized for his genetic-based research on lung disease and for development of novel therapies for critically ill patients with acute inflammatory lung disease. He has nearly 400 peer-reviewed publications. He has an expansive portfolio of NIH-sponsored research and continues to direct large federally funded programs.

Dr. Garcia is a passionate advocate for the training of physician-scientists and is an active supporter of minority medical and science students. He has nurtured many minority students at AHSC, UIC, Johns Hopkins University and the University of Chicago, guiding them into MD and PhD programs.

Dr. Garcia earned his Bachelor of Science in biology at the University of Dallas in 1976 and received his medical degree from the University of Texas Southwestern Medical School in 1980. He completed an internship and residency in internal medicine at the University of Iowa Hospitals and Clinics (1980-1983) and completed a fellowship in pulmonary and critical care medicine at Albany Medical College (1983-1985).

Research: 

Airway epithelial differentiation and mucous cell metaplasia in chronic airway diseases Mucous cell metaplasia and mucus over-production are hallmarks of almost all chronic airway diseases (e.g. asthma, chronic obstructive pulmonary diseases, cystic fibrosis, etc.) and significantly increase the morbidity and mortality. No therapy is available besides the mechanical suction. We are now investigating the function and regulation of mucin genes in asthma pathogenesis using both in vivo (gene targeting model, induced mouse model of asthma, as well as tissues and secretions from asthmatic patients) and in vitro (differentiated epithelial culture and cell line) models.

A new paradigm in virus-induced asthma exacerbation Airway rhinovirus (RV) infection is the major cause of asthma exacerbation, a severe precipitation of the symptom in otherwise stable asthmatics who are often still under the routine medication. Thus, asthma exacerbation may have a different pathogenic mechanism that is largely unknown at present. Among different asthma-inducing allergens, Alternaria (Alt) is a fungal species that causes asthma in arid and semi-arid areas. In collaboration with the researchers in Arizona Respiratory Center, we have found the shift of airway response to viral infection during Alt exposure, which promotes inflammation and depresses antiviral response. This shift causes further increase of viral production and inflammation, similar to what would happen in the airways of asthma exacerbation. We are currently investigating the potential underlying mechanisms using both in vivo and in vitro models.
