Employment and Education
Data Scientist (2021 - current)
Applying data science and machine learning to turn data into deeper insights, better strategies and smarter decisions.
Head of Data Science (2019 - 2021)
Applying data science and machine learning to support individualized learning recommendations and workforce planning.
Visiting/Research Fellow (2012 - 2019)
Kidney Disease Branch, NIDDK, NIH
My work involves developing novel diagnostics and therapies for the detection, grading, and treatment of acute kidney injury and chronic kidney disease. I have taken discoveries from in vitro and in vivo models through to pilot studies in humans working with clinical collaborators.
Recent projects include automated quantification of fibrosis in histology sections and analysis of blood pressure and glomerular filtration rate time series data.
Instructor (2015 - 2017)
Foundation for Advanced Education in the Sciences at NIH
Co-taught the BIOF309 Introduction to Python course. Developed the syllabus and taught the BIOF509 Machine Learning and Object-Oriented Programming with Python course.
PhD Student (2007 - 2012)
Centre for Cardiovascular Science, University of Edinburgh
The exosomal proteome as a source of biomarkers for human disease.
Supervisor: Dr James Dear
- Validated and implemented an exosome purification strategy from human urine
- Systematically investigated factors mediating the release of exosomes from an in vitro murine cortical collecting duct cell model
- Identified exosomes as being present in adult human cerebrospinal fluid (CSF)
- Investigated the urinary and CSF exosomal proteomes using tryptic digest and whole protein LC-MS/MS
MSc Student (2006 - 2007)
Cardiovascular Science Program, University of Edinburgh
Dissertation project: Endothelial cell microparticles as biomarkers of cell activation and dysfunction in sepsis.
Spring project: The Gap Junction Potentiating Peptide Rotigaptide Does Not Augment the EDHF Response in Rat Mesenteric Arteries.
