Bias Detection Tool Cohort Member

I joined a cohort working remotely on Algorithm Audit's bias detection tool. Specifically, I'm contributing to the NGO's Github repository and the tool's functionality on the Dutch NGO's website. We are applying the tool to a Dutch public sector use case and will write up our findings in a paper.

Graduate Teaching Assistant

As a Graduate Teaching Assistant (GTA) for Machine Learning, I ran weekly labs and marked the coursework. I also led four labs and a couple of tutorials for Data Structures every few weeks and I marked for this course too.

As a GTA for Machine Learning, I ran two weekly labs tutorials. In addition, I was the GTA for the AI Impact Accelerator module. I also led two tutorials and two labs for Data Structures every three weeks.

As a GTA for Artificial Intelligence, I ran two weekly online live tutorials where I made sure the students were confident with the material and the tutorial sheet answers. I also ran four virtual live labs each week where students worked on developing a successful pacman agent during the Autumn 2021 term.

As a GTA for Machine Learning, I ran two small group live sessions weekly for undergraduates covering the tutorial sheet for that week. I also was a GTA for the Big Data Technologies course. I ran three online live lab sessions weekly for masters students, helped answer any questions they had, and marked coursework.

PhD Mentor for DAAD Rise Worldwide Recipient

I hosted a German undergraduate student researcher over 8 weeks while she worked alongside me on my PhD research project. She was funded by the DAAD RISE Worldwide program. We collaborated with one another and wrote papers on the work we completed.

PhD Intern

I completed a 5 month (~two days a week) PhD Placement at RTA (prev. CDEI)--a part of the UK's Civil Service, enabling the trustworthy use of data and AI. I worked on two different projects: the Responsible Demographic Data and the Bias Review projects. I collaborated with colleagues on both projects, reached out to stakeholders and contributed to those discussions, and lead work in the Bias Review project. For London Tech Week 2022, I co-authored a blog post about demographic data collection and bias detection. I learned a great deal about the intersection of the technology, policy, and data ethics fields and am eager to stay involved with the tech policy space.

AI Robustness Researcher/Developer

Alongside three other PhD Student colleagues, I completed a literature review of AI Robustness methods, zoning in on NLP, weight-poisoning attacks, and poisoning detection methods. We developed a project combining state of the art AI Robustness and NLP research. I was the lead point person for communicating with our stakeholder, EY, every week over the 10 week project. To learn more about what we developed, check out our GitHub repository here: RobuSTAI.

Machine Learning Engineer Intern

While at HURIDOCS, I used state of the art ML explainability techniques to learn about a topic classification model. I improved the topic classification model performance for the Office of the UN High Commissioner for Human Rights. In addition, I documented software and processes for future ML Engineers and I was mentored by the Software Engineer, Gabriel Piles and I worked remotely from Seattle, USA.

Undergraduate Researcher on ML and Natural Language Processing (NLP)

While in Münster, I developed a successful ML/NLP framework to detect abusive language in English and German on Twitter at the the European Research Center for Information Systems with another undergraduate researcher. We implemented the steps of the ML pipeline alongside H2O Auto-Machine Learning in Python. I was mentored by PhD student Marco Niemann.

Undergraduate Researcher on Artificial Intelligence (AI)

I worked in the Distributed Systems Laboratory and collaborated with PhD Candidate Marie Ossenkopf who does great research on multi-agents. We built a deep learning framework that learned communication and coordination for a lever game. More specifically, we implemented a hierarchical deep reinforcement learning framework for a multi-agent system in Lua.
