Data Scientist (Math PhD) | Building NLP, RAG, and Mathematical Modeling for Human-Centered Research

Profile Summary

I am a PhD Mathematician and Data Scientist currently working on computational phenomenology and neuroimaging analysis. My work focuses on the technical integration of high-dimensional brain data with qualitative subjective reports. Focus Areas: Data Synchronization: I develop frameworks to align neuroimaging data (fMRI/EEG) with first-person narratives, identifying consistent neural markers for specific states. NLP & Narrative Clustering: I use NLP and semantic embeddings to categorize open-ended reports systematically. This approach identifies structures in qualitative data that standard assessments often overlook. Signal Extraction: I apply mathematical techniques to isolate signals within noisy, unstructured research datasets. I hold a Ph.D. in Mathematics from Purdue University. My experience as an Assistant Professor and Federal Data Scientist allows me to build the necessary infrastructure to turn interdisciplinary research into scalable, data-driven insights.
