About

I am a Staff Research Scientist at Visa Research. I'm interested in Representation Learning for Natural Language Processing and Computer Vision. My research aims to understand the geometry of embedded representations to enhance their interpretability and downstream task utility within the context of Multi-lingual Natural Language Processing, Computer Vision, Ethical and Responsible AI.

Bio

I obtained my Ph.D. in Computer Science from the School of Computing at the University of Utah, where I was advised by Jeff M. Phillips. Before coming to the University of Utah, I obtained an MS in Mathematics from the University of Texas at El Paso, where I worked on Stochastic Optimal Control Theory with Applications to Financial Mathematics under the supervision of Michael Pokojovy. I also hold a BA in Economics and Mathematics from the University of Ghana, where I worked under Mrs. Lilian Frempomaa Kyei.

Misc

Outside of research, I enjoy reading the word of God, praying and playing guitar. Here are a few of my favorite scriptures:

I can do all things through Christ who strengthens me. Philippians 4:13 NKJV

Now the Lord is the Spirit; and where the Spirit of the Lord is, there is liberty. 2 Corinthians 3:17 NKJV
