Spanning the Globe: Fall Updates from Education & Outreach

Suzanne Lenhart (center) and participants of the SAMSA-Masamu STEM Education Workshop.

NIMBioS Education & Outreach has been busy this fall with events that have spanned the globe.

  • Associate Director Suzanne Lenhart presented at the SAMSA-Masamu Program STEM Education Workshop in Tanzania in November. Held at Arusha Technical College in Arusha, the workshop included discussions with local teachers and college faculty about student STEM activities. Lenhart, who also represented UT where she is a Chancellor’s Professor in the Department of Mathematics, led a session on active learning activities. She co-presented with Jane White, a senior lecturer in math at the University of Bath in the UK and a short-term visitor to NIMBioS in November 2014. The SAMSA-Masamu Program is based at Auburn University. SAMSA is the Southern African Mathematical Sciences Association. The word “Masamu” translates to “mathematics” in the Southern African region, and so the SAMSA-Masamu program serves to promote U.S.-Africa collaboration in mathematics research. The workshop was a part of the SAMSA Annual Conference.
  • In October, Lenhart, NIMBioS Education & Outreach Coordinator Greg Wiggins, and former NIMBioS Postdoctoral Fellow Oyita Udiani represented NIMBioS at the Modern Math Workshop in Salt Lake City. Udiani gave a talk at the workshop, which is pre-conference to the annual SACNAS (Society for Advancing Chicanos/Hispanics and Native Americans in Science) Conference.
  • Lenhart helped establish a SACNAS Chapter at UT. Lenhart is serving as Chapter advisor.
  • NIMBioS was also represented at the annual Field of Dreams Conference in St. Louis in November where Christina Edholm, a postdoctoral teaching associate in UT’s math department, gave a talk.
  • More than 100 participants attended another successful Undergraduate Research Conference at the Interface of Biology and Mathematics. We have your photo album here!

The NIMBioS Education and Outreach program offers a diverse array of activities to meet the educational needs for learners of all ages including K-12 students and teachers, university and college student and faculty, professional industry audiences, and the general public. NIMBioS initiatives focus on the enhancement of education at the interface between mathematics and biology and promote cross-disciplinary approaches to science at all levels.

Enhancing STEM Diversity at Field of Dreams

Christina Edholm

Math students from diverse groups attended the Field of Dreams Conference in St. Louis this month to hear about graduate opportunities in the mathematical sciences, and NIMBioS was represented as a part of its commitment to enhance diversity in the STEM fields.

The annual conference is organized by the National Alliance for Doctoral Studies in the Mathematical Sciences (or “Math Alliance”) whose goal is to build a national community of scholars from underrepresented groups in the mathematical and statistical sciences.

Christina Edholm, a postdoctoral teaching associate in UT’s math department, attended on behalf of NIMBioS and gave a talk entitled, “What Is Infectious Disease Modeling?”

Edholm has been particularly active at NIMBioS, having served as a mentor last summer for undergraduates in our Summer Research Experiences program. She has also participated in various NIMBioS workshops, tutorials, and other programs.

Her research focuses on mathematical biology, specifically infectious disease modeling and pest management.

“I was able to expose my area of research to many different students, in addition to discussing my path to a post-doc and providing advice I had for navigating through academia,” Edholm said. “Overall, the conference provided a setting that provided students with opportunities and professional connections they might not otherwise have had access to. I feel the conference encouraged students from underrepresented backgrounds to see their futures in the mathematical sciences, through the examples of those who came before.”

Working Groups Tour SAL@NIMBioS

Working Group participants at NIMBioS this week tour the new Spatial Analysis Lab facilities. (L to R): Eric Carr, Christopher Remien, Karen Watanabe, Teresa Matthews, and Louis Gross

Synergy is the name of the game at NIMBioS, where visiting researchers from a variety of different backgrounds come together to learn from one another and produce great science. Hence, the combined effect is indeed greater than the sum of the individual parts. So was the case this week when Working Group participants visited the new Spatial Analysis Lab (SAL) at NIMBioS.

The Modeling Molecules-to-Organisms and Modeling Organisms-to-Ecosystems Working Groups were in residence this week at NIMBioS. Both groups coordinate closely with each other to achieve their goal to develop new modeling frameworks that link molecular responses through whole organism responses to ecosystem service delivery. This week’s meetings mark the fourth and final meetings for both groups, which have met three times at NIMBioS since 2015.

During a break in the proceedings, group members had a chance to tour the new SAL facilities. The lab offers state-of-the-art spatial analysis capabilities to researchers interested in understanding biological, geographic, and socio-economic processes. Services include large-scale data capture, collection, analysis, visualization, storage, training and outreach. The lab is directed by Mona Papes, an assistant professor of ecology and evolutionary biology at UT, along with Eric Carr as science coordinator. Carr is also NIMBioS’ computational data engineer. Read more about SAL.

NIMBioS Team Receives Best Publication Award

A paper on epidemic disease dynamics by a group of NIMBioS-associated researchers has won the prestigious Lord Robert May Best Paper Prize from the Journal of Biological Dynamics.

“The impact of spatial arrangements on epidemic disease dynamics and intervention strategies” was published in March 2016. Co-authors are Michael Kelly, a former NIMBioS graduate research assistant; Joseph H. Tien, who has been involved in several NIMBioS education and outreach events; Marisa C. Eisenberg, who has been an organizer of research and education and outreach events; and Suzanne Lenhart, NIMBioS Associate Director for Education and Outreach and a Chancellor’s Professor of Mathematics at UT.

Kelly is currently an assistant professor of mathematics at Transylvania University in Kentucky; Tien is an associate professor of mathematics at The Ohio State University; and Eisenberg is an assistant professor of epidemiology and mathematics at the University of Michigan.

The paper investigates the role of spatial arrangements on the spread and management of cholera, particularly the 2010 cholera outbreak in Haiti. The researchers examined the effect of human and pathogen movement on optimal vaccination strategies. They make vaccination recommendations based on the model. Among the findings are that more vaccinations can be administered when outbreaks occur downstream rather than upstream, as the directional flow of rivers affects pathogen movement.

The paper is available as open access at http://dx.doi.org/10.1080/17513758.2016.1156172

The prize is awarded at the biannual International Conference on Mathematical Modeling and Analysis of Populations in Biological Systems (ICMA), which will be held at the University of Arizona in October. The authors are invited to give a talk on the paper at the conference. They also receive a monetary award, free textbooks and a subscription to the Journal.

A Predator-Prey Model of Poverty Traps, New Paper from Ngonghala

Calistus Ngonghala (Mathematical Biology, Univ. of Florida) returned to NIMBioS last month for a short-term visit to collaborate with Olivia Prosper (Mathematics, Univ. of Kentucky). Ngonghala’s paper on poverty traps was recently published in Nature Ecology & Evolution.

Former NIMBioS postdoc Calistus Ngonghala has published a new paper that draws on economic, ecological and epidemiological models to examine the underlying drivers of rural poverty.

“General ecological models for human subsistence, heath and poverty,” published this month in Nature Ecology & Evolution, combine an economic model of growth accumulation with epidemiological and population ecological models. The authors show that the dynamics of poverty can be framed as predator-prey relationships, and that feedbacks between the biological and economic systems in this ecological-economic food web can lead to a state of persistent poverty.

The study finds that disease transmission and recovery rates are the most “consistently important” in determining long-term health and wealth dynamics. The findings are consistent with other studies that show improving health systems promotes economic growth and alleviates poverty.

The study was highlighted in the journal’s “News & Views” section in a commentary by Chris Desmond entitled, “The ecology of rural poverty.”

A NIMBioS postdoc from 2011-2013, Ngonghala is now an assistant professor of mathematical biology at the University of Florida.

In a press review for the paper, Ngonghala recounts his personal experiences of rural poverty growing up in Cameroon Africa that have inspired his research pursuits. “My family and friends had subsistence lifestyles, and my community suffered from a continuous burden of deadly diseases, such as malaria and HIV. These kinds of models are an essential step towards understanding persistent poverty and finding solutions for long-term sustainable development,” Ngonghala writes.

In a 2013 profile of Ngonghala in Scientific American, he elaborates on his childhood experiences and the reasons why he became a mathematician. The profile was one of series of profiles of mathematicians and computer scientists invited to participate in the 2013 Heidelberg Laureate Forum.

Ngonghala returned to NIMBioS last month on a short-term research visit to collaborate with Olivia Prosper, an assistant professor of mathematics at the University of Kentucky. The research evaluates the impact of human movement on the success of bednet programs for malaria control.

We always look forward to visits from former postdocs. Congratulations Calistus!
