David W. Niesel

David W. Niesel serves as an Adjunct Professor in the Department of Microbiology & Immunology at the University of Texas Medical Branch at Galveston (UTMB), with over 30 years of research experience in bacterial pathogenesis and diagnostic innovation.

His educational background includes:

• BA from Quinnipiac College (1975)
• PhD from North Carolina State University (1980)

Dr. Niesel's laboratory focuses on pathogenesis mechanisms of Gram-positive pathogens (e.g., Streptococcus pneumoniae) and Gram-negative bacteria (e.g., Salmonella, Shigella). His research encompasses in vivo virulence gene expression, host immune responses to infection, and novel diagnostic development. A key achievement is his patented rapid antibiotic resistance detection method (10-90 minutes, sensitivity to 10^-18 M), with four patents held including one pending. His work extends to microgravity environments and pre-vaccine attenuation mechanisms.

He conducts high-containment research at the Galveston National Laboratory using tier one select agents. His contributions bridge fundamental pathogenesis studies with practical diagnostic applications for combating antibiotic-resistant infections.
