Bio

I graduated from University of Texas Southwestern Medical School in 1986 and completed Internal Medicine and Infectious Diseases training at University of Iowa Hospitals and Clinics in 1993. 

Since coming to LSU in 1993, I have participated in several research projects during my career from laboratory-based to hospital quality projects. Most recently, I have been heavily involved in the development, implementation, and evaluation of infection prevention and antibiotic stewardship strategies in community hospitals in the LCMC Health system. My close relationship with the clinical microbiology laboratory as clinical consultant has augmented the antibiotic stewardship efforts for LCMC hospitals. I have the presenter for the weekly clinical microbiology conference for the last 20 years.

I have been involved with mentoring post-doctoral trainees as fellowship program director for 20 years. As division director of the LSU infectious diseases section, I have been intimately involved in coordination of clinical infectious diseases and public health response to COVID-19 at LSU Health and for LCMC hospitals.

Research

Proteoglycans and Atherosclerosis:

Prior to Hurricane Katrina (2005), my collaborator, Dr. Parakat Vijayagopal, and I were primarily focused on the role of arterial wall proteoglycans in the pathogenesis of atherosclerosis. We demonstrated that number of conditions including angiotensin II, smooth muscle cell proliferation, cholesterol enrichment, and phorbol ester led to the production of proteoglycan species that enhanced LDL binding.

Nutriceutical agents that induce weight loss: Along with Drs. Prasad and Vijayagopal, we discovered that a combination of grapeseed extract, caffeine, genestein and capsaicin produced significant weight loss in an obese Zucker rat model. These studies flowed as an extension of our studies to understand azaftig mechanism.

 

Clinical and Quality Improvement Research:

Since 2008, I have played a leadership role in the development of antibiotic stewardship program for hospital systems in south Louisiana. As part of that work, we have focused on improvement of antibiotic utilization in the care of patient with presumed infectious diseases. Through these efforts, our program at University Medical Center New Orleans has been designated as a center of excellence for antibiotic stewardship by IDSA.d PMID: 12054548.
