Computationally proficient research mathematician with expertise in Python, supervised deep learning, unsupervised deep learning for dimensionality reduction and latent space discovery, PyTorch machine learning frameworks, bash scripting, topology-informed regularization, and high performance computing. Highly adept at clustering and classification. I focus on synthesizing machine learning tools to find intimate trends in real-world phenomena, including biological and x-ray scattering images. My work is readily integrated with other fields, as evidenced by my collaborations with biologists, physicists, theorists, and experimentalists in other domains. Current work: leveraging sparsity to alleviate big-data problems. I augment existing convolutional neural network (CNN) ideas to create new architectures with many fewer (stochastically-connected) nodes/layers. This allows for the training of multiple leaner networks in parallel, which may then be aggregated or used for uncertainty quantification.Products: lead developer of DLSIA (Deep Learning for Scientific Image Analysis, formerly pyMSDtorch), a comprehensive PyTorch-based deep learning library for image analysis tasks, such as pixel-by-pixel segmentation, denoising, inpainting, and fast outlier detection (sub 1 ms for 64^ pixels). With a focus on user-customizability and a friendly API, DLSIA offers fast instantiation of Autoencoders, Tunable U-Nets, Mixed-Scale Dense Nets, and more.More generally: I work with many teams building end-to-end frameworks and solutions for a variety of machine learning tasks for image data, including x-ray scattering data (FXS, SAXS/WAXS, etc.) and biological image data from a variety of microscopy modalities (lattice light-sheet, FIB-SEM, cryo).Research interests include: - neutral collapse in applications to Security and machine UNlearning,- self-supervised ML for automated labeling, - CNN-derived latent/feature space exploration,- sparse deep learning architectures, - vision transformers, - sparse-sampling quadrature design.

Computer Vision Lead ScientistBerkeley Lab Nov 2022 - Jan 2024I build end-to-end machine/deep learning frameworks and solutions for large-scale image analysis tasks in many collaborations across an array of biological and x-ray scattering sciences. In my total time at Lawrence Berkeley National Lab, I have authored eight peer-reviewed deep learning-focused manuscripts (four as first author), with an additional two in preparation. In total, the following is a selected list of projects, findings, and general responsibilities:• Lead developer of DLSIA, or Deep Learning for Scientific Image Analysis, a comprehensive Python-based library focused on building deep learning workflows with user-defined architectures for scientific image analysis tasks, such as pixel-by-pixel, segmentation, denoising, inpainting, and automated out-of-distribution (OOD) detection.◦ In addition to coding development, I built and currently maintain all Git and ReadTheDocs web development (via Git/Sphinx sychronization) for showcasing and disseminating DLSIA tuto-rials and use-cases.• Employed sparsity techniques to augment existing CNN architectures, resulting in up to a 90% reduction in model size and inference speed from standard U-Net architectures.◦ Multi sparse network ensembling for semantically segmenting popular STAREdataset resulted in .83 F1 evaluation score, within 1.1% of current state-of-the-art,• Project lead in expanding automated label curation pipelines and applying super-vised deep learning techniques for sparse-label, pixel-by-pixel segmentation of sub-cellular structures on the sub-nanometer scale.◦ First to apply deep learning for structure discovery in highly resolved (two micrometer sized voxels) FIB-SEM imaging of C. Elegans eggs.◦ Responsible for all machine learning design and remote parallel training across 4+ GPUs.• Project co-lead, in collaboration with Lawrence Berkeley Lab’s Advanced LightSource, in developing self-supervised deep learning of tomographic reconstructionoperators. -

Graduate Student ResearcherUniversity Of California, Merced Sep 2014 - Nov 2019Merced, CaliforniaMy research fields included nonlinear dynamical systems, topological fluid dynamics, and mixing in viscous fluids. More specifically, by re-framing existing techniques in a computational geometric lens, I developed and implemented algorithms for extracting meaningful topological information and quantifying chaotic mixing in highly dynamic and nonlinear fluid systems from limited amounts of data.In a landmark for the chaotic dynamics community, I introduced the first algorithm for computing topological entropy in 3D flows that requires no detailed knowledge of the velocity field. -
Project Lead -- Descartes MentoringUniversity Of California, Merced May 2017 - Aug 2018Responsibilities include the design and implementation of a three-week 2017 Summer course in numerical analysis for second-year undergraduate students and a three-week 2018 Summer course serving as an introduction to data science and machine learning for third-year undergraduate students. Students from both years have taken inspiration from our summer work and have presented original research posters under my tutelage at the University of California, Merced Annual Summer Undergrad Research Symposium.Funding through NSF-sponsored Data-Enabled Science and Computational Analysis Research, Training and Education for Students (DESCARTES) Program. -

Math-To-Industry Bootcamp Iii -- Participating ScholarUniversity Of Minnesota Jun 2018 - Aug 2018University Of MinnesotaSix week session designed to provide graduate students in Mathematics with training that is valuable outside of academia. Daily technical skill building modules on machine learning techniques, statistical modeling, and optimization methods for decision-making processes culminated in two group capstone projects involving open-ended problems posed by industrial scientists.--Project 1: Sequence-to-sequence Modeling for the Business of BaseballApplied standard recurrent and convolutional neural network architectures on intimate Milwaukee Brewers baseball club fan and game data to dynamically forecast ticket sale on the most granular level possible. (Mentor: Keith Rush, Senior Manager of Data Science with the Milwaukee Brewers)--Project 2: Logistical Improvement for Minneapolis Bike-Share Using publicly available 2017 Nice-Ride data (detailing ~440,000 bike sharing trips) and augmenting with government weather records, my team is able to predict in real-time, using real-time 2018 data, the short-term (within 3 hours ahead) supply and demand for empty docks at each of the 100+ docking stations around Minnesota. By implementing basic linear regression, K-means clustering, and solving for shortest paths using optimization software AMPL, city workers can now predict the time and location in which docking stations will not meet customer demand (dock too full or empty) and have access to the optimal routes for bike reconfiguration that minimizes the number of problematic stations. -
