Kathy Ensor
{{Short description|American statistician}}
Katherine Bennett Ensor is an American statistician specializing in numerous methods in computational and statistical analysis of time series data, stochastic process modeling, and estimation to forecast issues in public health, community informatics, computational finance, and environmental statistics.
Ensor is the Noah G. Harding Professor of Statistics and Director of the Center for Computational Finance and Economic Systems at Rice University. From 2016–2022, she was Director of the Kinder Institute Urban Data Platform, a data resource initiative for the Greater Houston area that includes the Texas Flood and COVID-19 registries. She is an Executive Team Member for Houston Wastewater Epidemiology, a SARS-CoV-2 wastewater monitoring initiative between Rice University, the Houston Health Department, Houston Public Works, and the City of Houston. {{Cite web|title=curriculum vitae|url=http://ensor.rice.edu/curriculum-vitae/}} In August 2022, Houston Wastewater Epidemiology was named a National Wastewater Surveillance System (NWSS) Center of Excellence by the U.S. Centers for Disease Control and Prevention.{{Cite web|title=news and information/top-stories|url=https://hou-wastewater-epi.org/news-and-information/top-stories/}}
Career and Research
Ensor's statistical and computational methods for the development of modeling frameworks pinpoint, track and forecast issues across a wide variety of fields.
Since the start of her academic career, a focus of her research has sought a deeper understanding of problems in energy,{{Cite journal|last1=Raath|first1=Kim|last2=Ensor|first2=Katherine|date=23 June 2020|title=Time-varying wavelet-based applications for evaluating the water-energy nexus|journal=Frontiers in Energy Research|volume=8|pages=118|doi= 10.3389/fenrg.2020.00118|doi-access=free}} quantitative finance{{Cite journal|last1=Ensor|first1=Katherine|last2=Koev|first2=Ginger|date=25 July 2014|title=Computational finance: correlation, volatility, and markets|journal=WIREs Computational Statistics|volume=6|issue=5|pages=326–340|doi=10.1002/wics.1323|doi-access=free}}{{Cite conference|last1=Kyj|first1=Lada|last2=Ostdiek|first2=Barbara|last3=Ensor|first3=Katherine|date=22 March 2009|title=Covariance estimation in dynamic portfolio optimization: a realized single factor model|journal=American Finance Association Annual Meeting|doi=10.2139/ssrn.1364642|ssrn=1364642 |doi-access=free}} and risk management.{{Cite journal|last1=Ensor|first1=Katherine|last2=Glynn|first2=Peter|date=1 April 2000|title=Simulating the maximum of a random walk|journal=Journal of Statistical Planning and Inference|volume=85|issue=1–2|pages=127–135 |doi=10.1016/S0378-3758(99)00075-0|doi-access=free}} In 2002, she collaborated with university and industry partners to establish the Center for Computational Finance and Economic Systems (CoFES). She has since continued to serve as the center’s director and has developed numerous programs in graduate and undergraduate research and education.{{Cite web|title=cofes.rice.edu|url=https://cofes.rice.edu/}}
Ensor is widely known for her expertise in community analytics, which has grown through her career-long commitment to environmental and health-based research. Through collaborations with cross-disciplinary groups of educators, scientists, engineers, and city and public health professionals, she has quantitatively assessed air quality and human exposure to environmental contaminants. The work has also included the discovery of a correlation between ozone and heart attacks, and of geographic patterns in severe asthma attacks in schoolchildren.{{Cite journal|last1=Ensor|first1=Katherine|last2=Raun|first2=Loren|last3=Persse|first3=David|date=2013-02-13|title=A case-crossover analysis of out-of-hospital cardiac arrest and air pollution|journal=Circulation|volume=127|issue=11|pages=1192–1199|doi=10.1161/CIRCULATIONAHA.113.000027|pmid=23406673|s2cid=173692|doi-access=free}}{{Cite journal|last1=Raun|first1=Loren|last2=Ensor|first2=Katherine|last3=Persse|first3=David|date=2014|title=Using community level strategies to reduce asthma attacks triggered by outdoor air pollution: a case crossover analysis|journal=Environmental Health|volume=13|issue=1|page=58 |doi=10.1186/1476-069X-13-58|pmid=25012280|pmc=4108967 |s2cid= |doi-access=free|bibcode=2014EnvHe..13...58R }}{{Cite journal|last1=Raun|first1=Loren|last2=Jefferson|first2=Larry|last3=Persse|first3=David|last4=Ensor|first4=Katherine|date=August 2013|title=Geospatial analysis for targeting out-of-hospital cardiac arrest intervention|url=https://www.sciencedirect.com/science/article/abs/pii/S0749379713002729|journal=American Journal of Preventive Medicine|volume=45|issue=2|pages=137–142|doi=10.1016/j.amepre.2013.03.013|pmid=23867019}}
In May 2020, Ensor and collaborators at Rice University, the Houston Health Department, Houston Public Works, and the City of Houston, began conducting ongoing testing of the city’s wastewater treatment system for the presence of SARS-CoV-2, the virus that causes COVID-19.{{Cite medRxiv|last1=Stadler|first1=L.|last2=Ensor|first2=K.B.|last3=Clark|first3=J.R.|last4=Kalvapalle|first4=P.|last5=LaTurner|first5=Z.W.|last6=Mojica|first6=L.|last7=Terwilliger|first7=A.|last8=Zhuo|first8=Y.|last9=Ali|first9=P.|last10=Avadhanula|first10=V.|last11=Bertolusso|first11=R.|last12=Crosby|first12=T.|last13=Hernandez|first13=H.|last14=Hollstein|first14=M.|last15=Weesner|first15=K.|last16=Zong|first16=D.M.|last17=Persse|first17=D.|last18=Piedra|first18=P.A.|last19=Maresso|first19=A.W.|last20=Hopkins|first20=L.|date=2020-11-06|title=Wastewater Analysis of SARS-CoV-2 as a Predictive Metric of Positivity Rate for a Major Metropolis|medrxiv=10.1101/2020.11.04.20226191}}
The wastewater monitoring system has also been adapted to provide public health information on seasonal influenza, the respiratory syncytial virus (RSV), mpox and other human pathogens.{{Cite web|title=news and information/manuscripts|url=https://hou-wastewater-epi.org/news-and-information/manuscripts/}}{{Cite journal|last1=Hopkins|first1=Loren|last2=Persse|first2=David|last3=Caton|first3=Kelsey|last4=Ensor|first4=Katherine|last5=Schneider|first5=Rebecca|last6=McCall|first6=Camille|last7=Stadler|first7=Lauren |date=10 January 2023|title=Citywide wastewater SARS-CoV-2 levels strongly correlated with multiple disease surveillance indicators and outcomes over three COVID-19 waves|journal=Science of the Total Environment|volume=855|pages=158967|doi=10.1016/j.scitotenv.2022.158967|pmid=36162580|pmc=9507781 |bibcode=2023ScTEn.85558967H |doi-access=free}}
