As the Texan climate experiences increasingly extreme weather conditions like drought and flooding, cases of infectious diseases – once believed to be found only in the tropics – are now on the rise. One Texan researcher, who spent most of her career studying infectious diseases in every other corner of the globe, has found herself uniquely positioned to apply her global expertise in her home state…with a little help from her interdisciplinary friends at UT Austin.
A Molecular Bioscientist, Applied Mathematician and GIS Mapping Analyst Walk Into A Bar…
Katy Brown is a Senior Research Fellow in the Oden Institute for Computational Engineering and Sciences and she, along with other UT researchers – Professor Clint Dawson the Department Chair of Aerospace Engineering and Engineering Mechanics, Suzanne Pierce, a Research Scientist at Texas Advanced Computing Center (TACC), and Michael Shensky, Head of Data Services (and GIS mapping wizard) for UT Libraries – are key participants in a highly prestigious grant from the UK’s Wellcome Trust to analyze how flood modeling might help inform disease spread.
Born in Cambridge, England, Brown is one of those Texans with dual identities – both Austinite and Citizen of the World.
“My research has brought me across Asia, Australia, the Americas and Europe,” Brown said. Brown’s expertise has principally been focused on malaises– melioidosis and Chagas disease – infections most Texans would not be losing much sleep over.
But the Texan climate is now exhibiting many of the attributes found in subtropical regions such as South East Asia, Australia and South America, where such diseases thrive. Cases of patients contracting emerging “tropical” diseases are increasing in the US. Chagas disease, in particular, is being spread throughout Texas principally by kissing bugs.
Local medics aren’t always trained to diagnose, let alone treat, Chagas disease and information on how it spreads, like through contact with the seemingly harmless kissing bug, is still not widely available to the general public. “Left untreated it can be fatal,” said Brown.
Having spent most of her career focused on infectious disease, Brown is an expert in her field. But to accurately model the spread of Chagas disease in Texas required other skills sets, not to mention some unique thinking.
Clint Dawson has been modeling storm surge and flooding in the gulf coast region for decades – simulating every major hurricane from Katrina to Harvey. “My group is doing flood modeling in support of the disease modeling to understand how flooding impacts the spread of disease in coastal areas during and after heavy storm events,” said Dawson.
