Francis Clarke is recipient of 2015 W. T. and Idalia Reid Prize

Philadelphia, PA—Francis Clarke of Université Claude Bernard is the recipient of the 2015 W. T. and Idalia Reid Prize, awarded by the Society for Industrial and Applied Mathematics (SIAM).

Dr. Clarke has been awarded the Reid prize for his pioneering and influential work on the analysis of generalized derivatives and subdifferentials and for its applications in PDE optimization and control of nonsmooth systems.

Clarke received the award, a cash prize of $10,000 and an engraved medal, at the SIAM Conference on Control and Its Applications, held July 8-10 in Paris, France. His associated prize lecture, “Definitions and Hypotheses and All That Stuff,” also delivered at the conference, was very well received.

A faculty member at Université Claude Bernard in Lyon, France, Clarke also holds a chair in mathematical control theory at L’Institut universitaire de France. He received his Ph.D. from the University of Washington. Read the rest of this entry »

Jennifer Tour Chayes of Microsoft to deliver The John von Neumann Lecture

Philadelphia, PA— The Society for Industrial and Applied Mathematics (SIAM) is pleased to announce that Jennifer Tour Chayes of Microsoft is the 2015 John von Neumann Lecturer.

The flagship lecture, the highest honor awarded by SIAM, was established in 1959 in honor of the Hungarian-American mathematician after whom the prize is named. The lecture is awarded for outstanding and distinguished contributions to the field of applied mathematical sciences and for the effective communication of these ideas to the community.

The 2015 John von Neumann Lecture is awarded to Dr. Chayes for her leadership in the research community, as well as her seminal contributions to the study of phase transitions in both mathematical physics and the theory of computing.  As co-founder, Managing Director and Distinguished Scientist at Microsoft Research New England and Microsoft Research New York City, she has gone on to tackle network models and algorithms,  algorithmic game theory, and computational biology; through her multiple leadership roles, she continues to inspire and innovate.

Let policymakers know why STEM conferences are important!

Anyone who has ever been to a scientific or technical meeting knows the value of attending one: advancing research; learning about the latest in the field; networking with peers and other professionals; finding collaborators, students, and mentors; and participating in scientific discussions, to name just a few of the benefits.

While we know of the many and varied advantages of scientific meetings, it’s time to convince federal policymakers of the same. Since 2012, federal science agency employees and contractors have been subject to significant regulations and burdensome approval processes stipulated by government-wide policies. It has been shown by the Government Accountability Office and the White House Office of Science and Technology Policy that this has reduced overall conference participation by scientists and researchers at government agencies.

In order to help spotlight this issue, the American Association for the Advancement of Science (AAAS) has launched a campaign to elicit anecdotes that highlight the important role of STEM conferences from participants such as yourself. This is part of a larger community advocacy to loosen conference travel restrictions. Read the rest of this entry »

NSF Unsolicited Proposals for Quantitative Approaches to Biomedical Big Data (QuBBD)

From the NSF:

Dear Colleagues:

The explosion in the availability of health- and disease-related data from biological, biomedical, behavioral, social, environmental, and clinical studies is creating new opportunities for collaborative research. Innovative methodology for visualization, modeling, and analysis of biomedical big data is imperative to address the challenges posed by complex data structures such as images, networks, and graphs, missing and sparse data, and complex dependence structures and interaction effects.

One of the critical application areas at the interface of the biomedical and data sciences is precision (or personalized) medicine. The goal of precision medicine is to develop a targeted treatment (or prevention) regimen that takes into account unique characteristics of an individual such as genetic makeup, environmental factors, and lifestyle. Achieving the goal of precision medicine will require combining data across multiple formats and developing novel, sophisticated mathematical, statistical, and computational methods that facilitate high-confidence predictions for individuals.

Tristan van Leeuwen receives SIAM Activity Group on Geosciences Junior Scientist Prize

From the press office of Universiteit Utrecht: 

Tristan van Leeuwen of Utrecht University in the Netherlands received the SIAM Activity Group on Geosciences Junior Scientist Prize this year. The jury praised Van Leeuwen for his “exceptional contribution to the theory, algorithms and large scale computing of seismic inverse problems, and for his leadership in the field of mathematics based seismic imaging.” SIAM awards the prize to a young, promising researcher in the field of mathematics with an application in the geosciences every two years.

Van Leeuwen has been working as an assistant professor at Utrecht University’s Faculty of Science since 2014. He was pleasantly surprised to receive the prize: “I didn’t expect this. This international recognition has inspired me to remain active at the interface between mathematics and geoscience,” he said. Read the rest of this entry »

SIAM joins call to action for American Innovation Imperative

Philadelphia, PA–SIAM today joined scores of other organizations as well as leaders of American business, industry, higher education, science, and engineering in an urgent call to action for stronger federal policies and investment to drive domestic research and development. Ten CEOs and 252 organizations signed “Innovation: An American Imperative,” a document aimed at federal decision makers and legislators.  It underscores the findings—and warnings—contained in The American Academy of Arts & Sciences report, Restoring the Foundation: The Vital Role of Research in Preserving the American DreamRead the rest of this entry »

Mathematical models with complicated dynamics for disease study

nugget_iconPhiladelphia, PA – “The impact of human mobility on disease dynamics has been the focus of mathematical epidemiology for many years, especially since the 2002-03 SARS outbreak, which showed that an infectious agent can spread across the globe very rapidly via transportation networks,” says mathematician Gergely Röst. Röst is co-author of a paper published today in the SIAM Journal on Applied Dynamical Systems that presents a mathematical model to study the effects of individual movement on infectious disease spread.

“More recently, the risk of polio in Europe has been elevated by human migration, and many countries were concerned about the possibility of Ebola getting out of West-Africa,” continues Röst, who co-authored the paper with Diana Knipl and Paweł Pilarczyk.  “There are several mathematical tools that can help in assessing how mobility facilitates disease spread, including multipatch compartmental models which are suitable to describe local disease dynamics as well as travel patterns between distinct locations, such as major cities.” Read the rest of this entry »

Better fracking with computational models

The process of hydraulic fracturing , commonly known as “fracking”, involves injecting large volumes of water into impermeable rocks such as shale in an effort to create flow paths for fluids such as oil and gas. This process often generates tiny earthquakes (or microseismic events) which in turn can be used as passive seismic sources for imaging the subsurface. In this video, researchers Susan Minkoff and Rosalie Belanger-Rioux describe computational modeling techniques that can be used to estimate the location of these microseismic events and the uncertainty inherent in this process. They discuss microseismic event location in the context of hydraulic fracturing and modeling of methane hydrates. Watch the video!

Modeling coastal vegetation

Understanding the flow of water through complex coastal regions can be of interest for a number of applications, like wetland health and restoration, inland flooding due to tropical storms and hurricanes, and navigation through coastal waters. The existence of vegetation in coastal regions increases the flow resistance, which helps determine velocity and water level distribution in wetlands and inland. In this video, Steven Mattis of the University of Texas at Austin talks about computational modeling of flow and transport through idealized coastal vegetation in order to better understand it.
