This team is comprised of Lu Chen (one of Bal's PhD students), Nathan Cruz, Lori Harper, Michael Mathison, Balgobin Nandram, Jennifer Rhorer, Luca Sartore, and Tenopra Shepphard. This award was for terrific teamwork and technical expertise in implementing new Cash Rents statistics with an updated outlier identification process and a new modeling process. The second award, solely to Bal Nandram, was a Cooperator of the Year Award for his outstanding contributions in service to the Research and Development Division. These Awards for Excellence are for research that Bal Nandram has been doing for his prestigious grant award titled "Bayesian Models for Cash Rents of U.S. Counties".  


Congratulations to Jessica Wang and Ben Gobler for their excellent performance in this year's Kryptos competition

Ben and Jessica were among just nine of 77 teams who solved all three cryptography challenges.  (See here for the three puzzles, the first of which is included below.) Based on their solution to all the problems in the contest, Wang & Gobler achieved the TURING level of achievement and now should be referred to as “Master Codebreakers”.

The Kryptos competition is hosted annually by Central Washington University (coordinated by Professor Stuart Boersma); in their words "κρυπτοσ or kryptos, is a contest open to any and all undergraduate students. The theme of the contest is centered around the breaking, or cryptanalysis, of ciphers (secret writing)”.  This is not WPI’s first strong showing in the competition: last year, Forrest Miller and Avery Smith achieved BABBAGE level.

Guanying Peng awarded 3-year Grant from the National Science Foundation's Applied Mathematics Program

Assistant Professor Guanying Peng has been awarded a new 3-year grant from the National Science Foundation's Applied Mathematics Program. The project is titled From Differential Inclusions to Variational Problems: Theory and Applications.

In Guanying Peng's own words: Singularities are ubiquitous in nature. Examples include turbulence in fluid dynamics, folds in thin films, and defects in liquid crystals. The physical behavior around singularities is generally highly complex, posing great challenges to the efforts of understanding their formation, structure, and influence on neighboring regions. The knowledge of the nature of singularities is fundamental to predict a system’s behavior or to develop effective applications for a material. This project considers systems in continuum mechanics and materials science that can be described directly or indirectly by a class of partial differential equations (PDE). The main goals include developing novel mathematical methods for analyzing this class of PDE and applying such new methods to better understand the nature of their singularities.

Min Wu awarded 5 year, $450,000 NSF CAREER Award

The 5-year, $450,000 NSF CAREER Award is titled CAREER: Probing Multiscale Growth Dynamics in Filamentous Cell Walls. The Faculty Early Career Development (CAREER) Program offers the National Science Foundation's most prestigious awards in support of early-career faculty who have the potential to serve as academic role models in research and education and to lead advances in the mission of their department or organization. From Professor Min Wu's description of the proposed research: Various plants and fungi rely on filamentous growth to develop, reproduce, or survive under environmental stress. For example, the growth of root hairs with one-cell width effectively increases the surface area of the plant roots to absorb water and nutrients. Although experimental approaches have been able to track cell wall morphology and kinematics on the expanding cell wall surface for more than a century, the regulation of cell wall growth needs further elucidation. This project will develop mathematical models and computational methods to simulate the cell wall expansion due to the spatial patterning of new cell wall materials and mechanical interaction with the cell interior. Further, inference methods will be devised to predict the spatial patterning of wall-material trafficking from the cell wall geometry and quantify how volume growth inside the cell wall is distributed and rearranged to sustain the cell wall geometry during expansion and under mechanical constraints. The methods developed in this research can be applied to filamentous growth systems such as pollen tubes, root hairs, fungus hyphae, thus having significant implications in advancing agriculture and improving public health. Complementary to the research, the investigator will engage students, including K-12, undergraduate, and graduate students, in research mentorship, journal clubs, and a new interactive learning platform "Filaform”, to promote interest and transdisciplinary understanding of this biological process by leveraging geometry and other mathematics in conjunction with modern and emerging experimental techniques.

Zheyang Wu awarded $200,000 NSF Grant

The 3-year award is titled New Techniques to Combine Measures of Statistical Significance from Heterogeneous Data Sources with Application to Analysis of Genomic Data. Professor Wu is the PI on this award from the Statistics Program at the National Science Foundation.
In Professor Wu's own words:
This project is motivated by integrative analysis of large-scale genomic data, where an important question is how to effectively combine statistical significances, or p-values, from heterogeneous data sources. Despite recent advances in theoretical and applied studies, statistical and computational challenges remain in addressing critical data features, such as complex correlations, discreteness of data, and high availability of prior knowledge that could have been utilized to boost signal detection. This project will develop novel statistical methods to address the challenges and increase the statistical power for detecting valid signals. The research will facilitate innovations in statistical theory and methodology as well as in broad applications.

Joseph Fehribach Multivariable and Vector Calculus

Joseph Fehribach authors new textbook "Multivariable and Vector Calculus"

This carefully-designed book covers multivariable and vector calculus, and is appropriate either as a text of a one-semester course, or for self-study. It includes many worked-through exercises, with answers to all the basic computational ones and hints to those that are more involved, as well as lots of diagrams which illustrate the various theoretical concepts.  It is written at the level of the WPI courses MA 1024 Y and MA 1034, and we hope that it is followed in a couple of years by a second book on sequences and series in calculus, based on the material in MA 1033.

Bal Nandram receives USDA NASS grant to get reliable estimates of cash rental rates

In Professor Nandram's own words: This work at NASS is to develop Bayesian small area models to get reliable estimates of cash rental rates. I also advise researchers at NASS on the use of these small area models, which use Markov chain Monte Carlo methods extensively and routinely. NASS informs many crop insurance and agricultural support programs administered by other agencies.. Many farmers rent their lands to other farmers, and it is useful to know annually what a fair price is by practice (irrigated, non-irrigated, and pasture land) for each of 49 states consisting of nearly 3000 counties with nearly two million operations. Models must be operationalized to provide fast analysis and precise positive estimates of cash rental rates with standard errors. This is a very important on-going activity at NASS because NASS is responsible to the US government to perform this research activity.

Adam Sales receives Grant to Use Modern Measurement Models to Summarize Complex Implementation Data

In Adam's own words: Randomized field trials of interventions in education, health, and other areas often gather complex, rich data on how the intervention is carried out. For instance, in interventions involving educational technology, researchers gather computer log data of students' actions within the program. There is broad agreement that implementation data is important, but little guidance on how best to use it to understand treatment effects. This project develops a framework for using modern measurement models to summarize complex implementation data, and then to estimate different average treatment effects for groups of subjects who implement (or would implement) the intervention in different ways.

Adam is also a Co-PI on two other recent grants "Improving the Power of Education Experiments with Auxiliary Data" and "Direct adjustment in combination with robust or nonlinear regression: software and methods for RDDs, RCTs and matched observational studies"

Professor Oren Mangoubi Receives NSF/CCF Grant

The grant is titled “CRII: AF: Optimization and sampling algorithms with provable generalization and runtime guarantees, with applications to deep learning”. 

In Professor Mangoubi’s own words "The aim of this project is to design novel optimization and sampling algorithms for training deep learning and other machine learning models, and to prove guarantees on the running time, generalization error, and related robustness properties of these algorithms. Training algorithms with good generalization properties can lead to machine learning models which are more robust to changes in the dataset, allow for robust predictions, and help mitigate algorithmic bias when the training dataset may not be fully representative of the diversity of the population dataset."
