Freelancer Overview

As a Biomedicine graduate (2:1, Birkbeck University of London), I bring specialist knowledge across cell biology, molecular biology, physiology, pharmacology, and clinical content to data annotation work. I am currently contributing to three active biomedical annotation projects on Zooniverse - including mitochondrial mapping from SBF-SEM microscopy imagery in collaboration with Diamond Light Source and the Universities of Manchester and Southampton, blood cell classification from haematological smears, and reviewing and correcting AI-generated transcriptions produced by Amazon Textract. My biomedical background allows me to evaluate scientific and medical AI outputs at a level most general annotators cannot. I am experienced in following structured rubrics consistently across high volumes of tasks, producing accurate written assessments, and handling sensitive data to strict confidentiality standards.

Labeling Experience

ML Output Reviewer & Transcription Corrector | BHL Field Journal Project, Zooniverse

OtherTextTranscription
I reviewed and corrected AI-generated text transcriptions of digitized historical field journals. Using machine learning handwriting text recognition (HTR) outputs, I identified and resolved transcription errors. This process improved the accuracy and reliability of the final dataset. • Worked with outputs produced by Amazon Textract. • Mirrored standard professional workflows in AI model evaluation. • Provided corrected training data for future model improvements. • Supported biodiversity and scientific record-keeping projects.

Haematological Data Annotator | Rhesus Macaque Social Behaviour Study, Zooniverse

OtherImageClassification
I classified blood cell types from whole blood microscopy smears for a research study. This involved distinguishing cell types within a rhesus macaque population to support genetic and behavioral analysis. The work demanded accuracy and consistency across a large quantity of microscopy imagery. • Assisted in a study on the genetic basis for social behavior. • Applied haematological expertise to image classification tasks. • Consistently handled high data volumes. • Ensured reliability in cell type identification for research purposes.

Biomedical Image Annotator | Placenta Profiles – Mito Mapper, Zooniverse

OtherImagePoint Key Point
I performed annotation of high-magnification serial block face scanning electron microscopy (SBF-SEM) images. My task was to identify and map mitochondrial locations within syncytiotrophoblast cells of human placental tissue. Precise, consistent placement of annotation markers was required for each complex image. • Contributed to collaborative research on placental dysfunction related to pre-eclampsia. • Applied specialist biomedical knowledge to improve annotation accuracy. • Ensured strict consistency and attention to detail during labeling. • Worked as part of a multi-institutional academic team.
