Freelancer Overview

As a neuroscientist with over six years of experience in experimental design, behavioral data analysis, and signal interpretation, I have extensive practice in labeling, categorizing, and validating complex datasets. During my PhD, I developed and annotated large-scale behavioral and optogenetic datasets in MATLAB and GraphPad Prism, applying precise tagging and classification of events for statistical and computational analysis. My work involved manual and automated labeling of behavioral sequences, event detection, and validation of neuronal activity traces, which directly aligns with the core skills required for data labeling and AI training. I am proficient in identifying patterns, ensuring data quality, and maintaining consistency across large data collections. In addition, I have experience mentoring students in scientific data analysis and using structured annotation workflows — skills that translate well into high-quality data labeling for AI models. My attention to detail, strong scientific background, and bilingual proficiency (English–Spanish) allow me to contribute effectively to diverse AI training projects.

Behavioral Event Annotation in Neuroscience Experiments

OtherVideoClassificationAction Recognition
During my PhD, I designed and annotated large-scale behavioral datasets from transgenic mice performing reward-related tasks. I manually labeled licking events, behavioral sequences, optogenetic stimulation periods, and artifact-free signal segments. I also validated time-series data from fiber photometry recordings, ensuring accuracy, consistency, and high-quality event tagging. My work required strict adherence to predefined criteria, inter-trial consistency checks, and verification of data quality before statistical analysis. I developed structured annotation workflows and collaborated with students to maintain unified labeling criteria across long-term experiments.
