Short Biography

Dale received a B.S. in Microbiology in 1990 from the Department of Biology, University of South Florida (USF). In December of 1994 he received a Master of Science in Public Health, with a research focus on methods development (IMS-multiplex-PCR, dot blot) for the detection of two pathogenic protozoa (Cryptosporidium parvum and Giardia lamblia) in environmental samples, from the College of Public Health, USF.  In December of 1999 he received a Doctorate of Philosophy with a research focus on the use of molecular methods for detection of water quality indicator microorganisms and pathogenic viruses in fresh and marine waters from the Department of Marine Sciences, USF, St. Petersburg, Florida (major advisor, Dr. Joan B. Rose). In his first Post Doctoral position at USF’s College of Marine Science, he worked with Dr. John H. Paul III on human enterovirus detection assays, marine lysogeny and isolation of viruses lytic to the red-tide agent Karenia brevis. In his second Post Doctoral position at the United States Geological Survey in St. Petersburg Florida, he worked with Dr. Eugene A. Shinn on a NASA funded grant to study microbiology and public health issues associated with atmospheric transatlantic transport of African dust to the Caribbean and Americas. He has been awarded Master Certificates in Six Sigma and Lean Enterprise Solutions by Villanova University. Dale is currently employed by the U.S. Geological Survey as an environmental public health microbiologist and is working on microbial water quality issues and long range dust storm associated dispersion of microorganisms around the globe.

Global transport of microorganisms and toxic compounds in clouds of desert dust

Image of Current Focus for Global transport of microorganisms and toxic compounds in clouds of desert dust

One of the most surprising bits of trivia about this field of science is how few scientists are actively involved in research. Long range dispersion of microorganisms, nutrients, and toxic compounds via our atmosphere may impact the health of downwind native ecosystems, crops, livestock, and humans (and there is the benefits of dust transport - many terrestrial and marine plants in downwind environments derive nutrients from dust). At the microbial scale it is not hard to imagine how this mechanism may influence the presence of species and genetic elements in any potential downwind environment no matter the distance.........this is a wide-open and lightly explored field....are you interested?
