2017-Pres | Visiting Postdoctoral Fellow, National Cancer Institute, NIH: I am currently in Jennifer Jones’ lab developing a high-throughput, scalable, clinical pipeline for characterizing extracellular vesicles for their use as clinical biomarkers. This work has required me to develop assays but also develop standalone software for the standardization of results as well as perform multidimensional data analyses.
2016-17 | Senior Research Assistant, University of Southampton: Following my PhD, I was funded in-kind by ThermoFisher Scientific to continue developing a high-sensitivity flow cytometry platform and standardization methods to characterize extracellular vesicles.
2014-15 | Tutor, The Brilliant Club: In this role I designed an 8-week course to teach to 2 classes of 14-15 year-old children at schools from underprivileged backgrounds. This initiative run by the Brilliant Club is to help increase the variety of students in STEM fields at the top universities in the UK by having PhD students and postdoctoral researchers teach their specialty. The course that I delivered was on basics of flow cytometry and extracellular vesicles. One of my students was selected by peer review for having done outstanding work and had their final project published in the organization journal.
2013-16 | Lab Demonstrator, BIOL2010: The Flow of Genetic Information, University of Southampton: In this position I taught groups of 30 students per week how to perform bacterial transformation and determine whether it was successful or not. I would then mark their subsequent write up of their lab results. I chose to take this position to gain experience in disseminating knowledge to students as well as to gain experience teaching large groups.
