As a senior MLE, I have* Helped develop the core embeddings algorithm for musical tracks that remains predominantly stable* Reduced training time of the core embeddings algorithm by 30%* Roadmapped and helped build an instruction fine-tuned multimodal model for recommendations that understands internal catalog vectors* Developed the in-house multitask, instruction fine-tuned language embeddings and masking model that extends bge-m3's capabilities to inferface with the multimodal model and is adapted to the Spotify corpus* Created a novel unsupervised compositing algorithm that represents collections of embeddings much more effectively than averaging -- relative improvements between 2% and 100% on various recommendation metrics.

I lead the deep learning, algorithm, and general AI R&D efforts at ResoluteAI. My R&D efforts thus far comprise:* Developed prototype neural network, Green gauge network (GGN), that outperforms Transformers on autoencoding and autoregression tasks* Developed approximate nearest neighbors search with O(1) complexity that outperforms ANNOY, SCANN (before SCANN was published)* Developed novel locality preserving hashing algorithm for mapping vectors in Euclidean space to bit vectors in Hamming space. This is used as an intermediate step in the nearest neighbor search algorithm.* Used GGN-based language model and ANN search to create a semantic search engine using NLUGeneral duties include:* Stay abreast of SotA research; implement as necessary. Solve ML problems as the need arises.* Consult with customers to lead sales-driven product creation.* Collaborate with marketing.

As the "Xpert" in deep learning and natural language processing for the data science specialty area at Excella, I cultivated our team's capabilities, engage with the DC data science community, and help define the cutting edge in the field. I leveraged my extensive background in mathematical modeling to:* Architect and build a machine learning-driven QA engine for USCIS, dubbed 'DALE' internally.* Discover the emergent Lie group structure of RNNs and word embeddings trained end-to-end on NLP tasks. • Develop a novel word embedding scheme, termed LieGr (Lie Group Embeddings), utilizing the results of the above mentioned exploration. Words are embedded as elements of a Lie group. Benchmarks vs other models in preparation.* Develop the state-of-the-art text generation network using a novel GAN architecture (YukawaGAN) and novel RNN (GaugeNN).

Broadly, NLS Analytics develops extremely general metrology techniques and apparati for perturbatively nonlinear systems. Nonlinear dynamical processes and interactions influence a wide variety of physical systems of fundamental and applied signifi cance, and understanding the properties of the systems subject to these dynamical processes is critical to everything from the advancement of MEMS technology to personal health monitoring.NLS Analytics focused on applications of the broader approach to atomic force microscopy (AFM) and has nearly completed a prototype of a quantitative technique and delivery vector that retrofits existing AFM systems via their signal access module and enables high-throughput, dynamic quantitative imaging of materials, particularly viscoelastic and biological materials, in a manner that circumvents the need to characterize the cantilever tip geometry.

PhD student in particle theory studying aspects of AdS/CFT with focus on the AdS side.For my thesis, I proved the Goldstone equivalence theorem and an arbitrary-order tensor generalization of it in AdS. I additionally created a lift formalism that extended the smearing technique for large-N conformal theories.Beyond the scope of my thesis work, I worked on composite Higgs and exotic physics models. As a humorous point of pride, by a day I was "successfully scooped" by Nobel laureate Glashow on proving superluminal neutrinos could not have been observed at Opera.
