Ionescu receives NSF CAREER award to study ‘molecular mechanisms of skeletal growth’
“This Faculty Early Career Development (CAREER) award will focus on elucidating the molecular mechanisms of skeletal growth. … Estrogen plays a vital role in growth plate closure for both sexes [of mammals] by converting androgens to estrogens through aromatase in growth plate cartilage. Deficiency or resistance to estrogen leads to growth plate fusion failure and ongoing height increase in adulthood. However, the exact mechanism by which estrogen regulates growth plate closure is still unknown. Understanding this mechanism may clarify species-specific skeletal differences or variations between bones from different anatomical locations.”

‘Covalent Inhibition of Pro-Apoptotic BAX’
“BCL-2-associated X protein (BAX) is a promising therapeutic target for activating or restraining apoptosis in diseases of pathologic cell survival or cell death, respectively. In response to cellular stress, BAX transforms from a quiescent cytosolic monomer into a toxic oligomer. … In this study, we performed a disulfide tethering screen to discover C126-reactive molecules that modulate BAX activity. We identified covalent BAX inhibitor 1 (CBI1) as a compound that selectively derivatizes BAX at C126 and inhibits BAX activation by triggering ligands or point mutagenesis.” Find the paper and full list of authors at Nature Chemical Biology.

Vision paper: ‘Towards Mobility Data Science’
“Mobility data captures the locations of moving objects such as humans, animals and cars. With the availability of GPS-equipped mobile devices and other inexpensive location-tracking technologies, mobility data is collected ubiquitously. In recent years, the use of mobility data has demonstrated significant impact in various domains including traffic management, urban planning and health sciences. In this paper, we present the emerging domain of mobility data science. Towards a unified approach to mobility data science, we envision a pipeline having the following components: mobility data collection, cleaning, analysis, management and privacy.” Find the paper and full list of authors at ArXiv.

‘Distributed Cognition Approach to Understanding Compensatory Calendaring Cognitive Systems of Older Adults With Mild Cognitive Impairment’
“While consumer digital calendars are widely used for appointment reminders, they do not fulfill all of the compensatory functions that are supported by calendars designed for cognitive rehabilitation therapies. … We employed a Distributed Cognition framework to elucidate how older adults with mild cognitive impairment (MCI) and their care partners manage calendaring details when supported by a traditional rehabilitation calendar. … We used a Distributed Cognition framing to articulate information flows and breakdowns in participants’ calendaring systems.” Find the paper and full list of authors in the International Conference on Ubiquitous Computing and Ambient Intelligence proceedings.

‘An Efficient OFDM-Based Monostatic Radar Design for Multitarget Detection’
“In this paper, we propose a monostatic radar design for multitarget detection based on orthogonal-frequency division multiplexing, where the monostatic radar is co-located with the transmit antenna. The monostatic antenna has the perfect knowledge of the transmitted signal and listens to echoes coming from the reflection of fixed or moving targets. We estimate the target parameters, i.e., range and velocity, using a two-dimensional periodogram. By this setup we improve the periodogram estimation performance under the condition of low signal-to-noise ratio using Zadoff-Chu precoding and the discrete Fourier transform channel estimation.” Find the paper and authors list at IEEE Access.

‘DREiMac: Dimensionality Reduction With Eilenberg-MacLane Coordinates’
“DREiMac is a library for topological data coordinatization, visualization, and dimensionality reduction. Currently, DREiMac is able to find topology-preserving representations of point clouds taking values in the circle, in higher dimensional tori, in the real and complex projective spaces, and in lens spaces. In a few words, DREiMac takes as input a point cloud together with a topological feature of the point cloud (in the form of a persistent cohomology class), and returns a map from the point cloud to a well-understood topological space.” Find the paper and full list of authors at the Journal of Open Source Software.

Halacheva receives NSF grant for representation theory research
“This project delves into several research directions within representation theory, which is the mathematical framework for studying objects through their symmetries and the operations which preserve them. Such operations can carry a classical, or even more intriguingly a quantum algebraic structure. … Quantum groups and the theory surrounding them are now a thriving source of uncovering new mathematical principles. This project will develop a richer understanding of this theory by building a common ground for combining algebraic, combinatorial and higher-structural categorical techniques for the study of quantum groups and associated diagram algebras.”

Zhu receives NSF grant for ‘Microlocal Analysis and Singularities’
“Degenerations and singularity formations play important roles in the study of differential geometry and arise naturally in multiple other areas of mathematics, including, algebraic geometry, mathematical physics, number theory and representation theory. This project concerns the geometry of singularities and has interesting connections with an array of disciplines including modeling of electromagnetic systems, gauge theory and string theory. Building on her track record, the PI plans to use effective techniques to solve a wide variety of problems and discover new and sharper analytic results. Alongside her research, the PI will engage in various outreach activities.”

Laredo receives NSF grant to bridge ‘classical and quantum symmetries’
“This project stems from the recent discovery that quantum groups naturally arise from the Stokes data of differential equations associated to classical symmetries. The main goals are to further explore this bridge between classical and quantum symmetries. Of particular interest is the extension to difference equations, which are natural discretisations of differential equations, and whose Stokes data are not well-understood beyond the one-variable case. Another important direction will the study of the integrable systems, or constants of motion, corresponding to these differential and difference equations. The project will provide research training opportunities for graduate students.”

Bi receives NIH grant for ‘biophysical modeling for collective tissue mechanics’
“Organ surfaces, made of epithelial or endothelial cells, serve as physical barriers. These cells are generally static but can transition to a dynamic, migratory state during physiological processes like development and repair. … Key questions remain about how curvature affects cell collective movement and the mechanics of multilayered tissues like mammalian epidermis. … To address these gaps, I plan to develop computational models that go beyond the conventional 2D approach, incorporating curved and multilayered 3D surfaces. This will include new models exploring the biomechanical relationship between nuclear shapes and cell proliferation.”

Schultz receives NOAA grant to study carbon dioxide removal

We will do so by developing a new model for the ocean sediment and benthos that can be coupled to existing ocean models to simulate these strategies and quantify their effect on the carbon cycle as well as understand potential feedbacks that could impact the ocean ecosystem.”

Dong receives DOE grant for quantum algorithm research
“Simulating the electronic structure of molecular systems using noisy intermediate-scale quantum devices is one of the most promising applications of quantum computing. Large-scale electronic structure and dynamics simulations, such as excited-state simulations of large molecules or a large number of molecules, are instrumental to the development of next-generation technology for energy applications. In this project, we will develop a framework that efficiently translates quantum algorithms from a gate-based quantum computing model to one that can be efficiently run on a near-term quantum annealer to enable large-scale electronic structure theory simulations across different quantum computing architectures.”
