Creating engaging stories and roleplaying experiences by combining human storytelling and the latest in AI

• Designs and builds large language model (LLM) applications for natural language interactions, retrieval augmented generation (RAG), and other generative text and image applications.• Programs computer vision applications for real-world unstructured data classification• Advises and directs projects in ML predictive modeling, feature extraction from text and image data, and classification on rich unstructured data.• Assesses and presents summarized potential value of applying latest AI/ML techniques to business use cases.

• Led the Recommendation Systems team of 5-7 ML scientists and engineers, responsible for algorithmically producing product recommendations and personalizing engagement with customers across the website and emails.• Coordinating extensively with product managers, owners, and business units to align development roadmaps and implement identified opportunities for increased user conversion.• Designed and built an embedding pipeline for product text data leveraging fastText and Faiss.• Designed and led development of a realtime ML recommendations pipeline that incorporates both same-session user site interaction signals and past-session historical data to personalize product recommendations.• Led development and implementation of product image embeddings leveraging deep CNNs to capture visual qualities of products.• Produced novel multi-input embeddings that simultaneously capture all available product data sets with varying catalog coverage in a single representation.

• Designed and implemented a model training, validation and selection pipeline for producing assessments of video interviews.• Selected, adapted, and trained a deep neural network architecture for transcribing English speech to text.• Designed and trained deep neural net demographics prediction models for monitoring algorithmic bias in hiring.• Developed and implemented algorithmic solutions for measuring and mitigating demographic biases in video interview assessment models.

• Designed and performed density functional theory (DFT) calculations to investigate problems in point defect energies, point defect diffusion barriers, molecular catalysis, and crystallographic phase transitions. Configured and managed computations on large supercomputing clusters. • Discovered a possible mechanism for room-temperature vacancy diffusion contributing to a specific device failure mode in AlGaN HEMT devices. Expected relevance for other high-field semiconductor devices with charged point defects.• Identified Fe-porphyrin as a potential self-cleaning catalyst for room-temperature reactions between DNT and atmospheric O2. Characterized reaction pathways and activation barriers for the reaction.• Configured and managed computations on large supercomputing clusters.• Regularly prepared and presented both oral and published reports of my work for a broad audience.

• Independently designed and implemented an iterative system identification algorithm that creates nonlinear differential equation models of time series data. Algorithm became basis of further work and development by other group members. • Wrote detailed notes on design and implementation of system identification algorithm for future reference and development. • Designed, implemented and documented a graphical user interface (GUI) for the system identification program.

• Analyzed theoretical data to assess behavior of computer models. Managed data collection, analysis and presentation.• Designed and programmed a model simulating the pressure, size and temperature dynamics of insonified gas bubbles patterned after the Galerkin spectral method. • Ran simulations using a multipole model of multiple scattering of acoustic and electromagnetic waves in media with dispersed spheroidal inclusions. Identified spectral trends useful for characterizing inclusions by ultrasonic probing. Performed data analysis and prepared visual presentations of relevant data features.

• Responsible for equipment and materials cleaning and maintenance. • Independently performed a wide variety of diagnostic tests on soil samples.
