Oren Mangoubi receives Google Research Scholar Award Grant
Oren Mangoubi is the PI for this research project titled Matrix Diffusions for Differentially Private Linear Algebra. In Oren's own words: As the collection of big datasets and applications of machine learning algorithms to different areas of people's lives have proliferated in recent years, privacy breaches of individuals' data in medical, census, and other sensitive datasets has led to increasing concerns. Consequently, methods which add random noise to machine learning algorithms to preserve a given level of differential privacy have become increasingly sought-after in science and industry. This award studies the use of matrix-valued diffusions to add noise to machine learning algorithms, in order to preserve the privacy of sensitive datasets while minimizing the resulting loss in the utility of these algorithms to researchers.

MAC majors compete in MAPFRE case competition
MAC majors Ngoc (Emerald) Pham, Eric Murdza, Gianni Camileo, and Kevin McGonigle competed on September 27, 2022, in an all-day case competition put on by MAPFRE. They collaborated together to determine the best combination of rates, reinsurance, expenses, and investments in order to maximize their total business value in a simulation. This competition relied on actuarial insurance, finance, and business knowledge to arrive at a solution where key decisions were presented to the audience and judges. The WPI team came in third place and competed against teams from local universities, including students in graduate programs. The group felt the competition was a remarkable way to learn how an insurance company must manage risk in a competitive market.
Congratulations to Emerald Pham, Eric Murdza, Gianni Camileo, and Kevin McGonigle! And Congratulations to our Actuarial Advisors, Profs. Jon Abraham and Barry Posterro for their leadership in the program!
Francesca Bernardi awarded 5-year Simons Foundation Collaboration Grant for Mathematicians
Francesca Bernardi awarded new Simons Foundation Collaboration Grant for Mathematicians titled "Investigating diffusion and transport at the microscale." This 5-year grant is designed to enhance research through travel and inviting collaborators to WPI.
In Francesca's own words: "This funding will support my ongoing collaboration with the Harris Lab of PI Daniel M. Harris in the School of Engineering at Brown University. We developed a model based on the Fick-Jacobs equation suitable to describe diffusion in microchannels with dead-end pores of non-uniform cross-sections; experiments benchmarking this model are currently undergoing in my lab at WPI LEAP as part of an MQP project. Next, we are getting ready to consider the "reverse problem" to what we are currently working on, i.e. dislodging trapped particles from micropores, as well as diffusion in microchannels with wavy, absorbing, or superhydrophobic walls."
For more information on this program, please see the Simons Foundation webpage.
Sam Walcott receives 3-year NSF award
Sam Walcott received the award from the Integrative Research in Biology (IntBIO) Program within the Directorate for Biological Sciences. This 3-year NSF award is titled "IntBIO: Linking genome to phenome to understand function of an ancient muscle myosin". This award is joint with Nicolai Konow (UMass Lowell PI), Jeffrey R. Moore (UMass Lowell), and Matt Gage (UMass Lowell). Sam is the PI on the WPI portion of the award and this collaborative research builds on a previously awarded WPI and UMass Lowell seed grant for interdisciplinary research.
In Sam's own words: Many animals have unique muscle proteins that occur in their jaw muscles. This muscle appears to be both strong and fast, violating the usual trade-off between muscle strength and speed where strong muscles are slow and fast muscles are weak. Rodents provide a unique system to examine these muscles since, of the two common types of squirrels around here, gray squirrels have these muscle proteins while red squirrels do not. In this project, my collaborators at UMass Lowell will collect data from red and gray squirrels at the scale of whole animals, isolated muscles, isolated muscle cells, and purified and engineered proteins. I will develop and use mathematical models to tie the experimental results together. In this way, we will determine how this muscle protein works and the trade-offs that have driven squirrel jaw muscle evolution.
Francesca Bernardi receives 3-year NSF award
Assistant Professor Francesca Bernardi received a new award from the National Science Foundation's Division of Chemical, Bioengineering, Environmental, and Transport Systems Program.
The 3-year NSF award is titled "Collaborative Research: Prechlorination, aging, and backwashing effects on spatiotemporal ultrafiltration fouling: Optimizing productivity by combining experiments and theory". This award is joint with Nicholas Cogan (Florida State University) and Shankar Chellam (Texas A&M). Francesca is the PI on the WPI portion of the award.
In Francesca's own words: This project aims at improving hollow-fiber ultrafiltration processes for wastewater reclamation. Numerous municipal facilities in the United States (and worldwide) utilize this mechanism to purify water for potable reuse. Typically, as wastewater flows through these hollow-fiber membranes, impurities are captured and occlude the pores in a process called "fouling;" this reduces the filtration efficiency and water production. Our project takes a synergistic approach by combining experimental investigations (at Texas A&M) with modeling and optimization efforts (at WPI and at FSU) to build theoretical/computational models of these membrane operations, which includes the spatiotemporal dependence of fouling and the effects of fiber geometry and packing density.
For more information, please see this NSF page.
Professor Gu Wang awarded 3-year NSF Grant
This 3-year award is titled Optimal Contracts and Optimal Stopping. Gu Wang is the PI on this award from the Applied Mathematics Program at the National Science Foundation.
In Gu's own words: This project analyzes how contractual compensations are optimally designed and terminated in a principal-agent relationship, and the potential moral hazard due to the information asymmetry between the two parties. The goal is to develop new tools and strengthen existing ones in the optimal contract theory to incorporate optimal stopping, jump diffusions and agents who control the diffusion coefficient of the state variable. The expected results help us understand the agents' behavior under different contracts and have concrete applications in practice, for example, the risk exposure of portfolios chosen by asset managers for their investors, and the withdrawal behavior of insurance policy holders, which help regulate and design financial products, and improve welfare distribution among market participants.

Professor Chris Larsen receives 3-year National Science Foundation's Applied Mathematics Program award
Professor Chris Larsen receives 3-year award from the National Science Foundation's Applied Mathematics Program. The project is titled Variational Fracture with Loads.
In Professor Chris Larsen's own words: Until recently, variational models for static and quasi-static fracture have been limited to Dirichlet boundary conditions, since there do not exist solutions to the seemingly most natural formulation that includes Neumann boundary conditions, i.e., boundary loads. The aim of the project is to improve on a recently introduced static formulation for variational fracture with boundary loads which can have solutions, and to extend this static model to the quasi-static case.
For more information, please see the NSF Award Info.
Professor Sam Walcott awarded WPI and UMass Lowell Seed Grant for Interdisciplinary Research
Sam Walcott has been awarded a new WPI and UMass Lowell Seed Grant for Interdisciplinary Research. The research project is titled “Interdisciplinary understanding of muscle across scales: recovery after injury” and is a collaborative project with the following faculty from UMass Lowell: Nicolai Konow (Department of Biological Sciences), Jeffrey R. Moore (Department of Biological Sciences), and Matt Gage (Department of Chemistry).
In Sam's own words: To generate movement, humans and animals activate their muscles causing them to shorten. Muscles also sometimes act as brakes to dissipate energy, an eccentric contraction, where the muscle is forcibly lengthened after activation. Eccentric contraction damages muscle causing muscle soreness. Muscle then adapts to this damage, changing its molecular make-up and ultrastructure. In this project, we are examining this process across size scales. The Konow lab (UMass Lowell) will measure changes in whole muscle force generation for mice with and without damaging eccentric contraction; the Gage Lab (UMass Lowell) will measure changes in RNA and protein expression in those muscles; the Moore Lab (UMass Lowell) will use in vitro assays to measure changes in protein function in those muscles at the molecular and cellular scale. My role in the project is to use mathematical modeling to tie these experimental measurements together across the size scales -- roughly 7 orders of magnitude -- they span.

Professor Balgobin Nandram awarded Grant from the National Agricultural Statistics Service (NASS, USDA)
The grant is titled "Bayesian Models for Cash Rents and Planted Acres of U.S. Counties". This grant is for the period May 2022 to April 2023 and the award is $224,882.
In Balgobin 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 such as the Farm Service Agency (FSA) and the Risk Management Agency (RMA). 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. Data are collected in the annual Cash Rent Survey and other sources of information (e.g., the Census of Agriculture) are also used, particularly last year's data. It is also important to estimate planted acres ahead of time. 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 in the Research and Development Division at NASS because NASS is responsible to the US government to perform this research activity.
Balgobin Nandram receives two USDA National Agricultural Statistics Service (NASS) Awards for Excellence
Professor Balgobin Nandram receives two awards for excellence from the National Agricultural Statistics Service (NASS), part of the United States Department of Agriculture (USDA).

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.

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.
For further information on this award, please visit: https://ies.ed.gov/funding/grantsearch/details.asp?ID=4544
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."
