I’m Derek Driggs, a researcher in machine learning and optimization.

I am currently pursuing a PhD in the Cambridge Centre for Analysis at the University of Cambridge under the supervision of Prof. Carola-Bibiane Schönlieb.

I am grateful to be a Gates Cambridge scholar and a member of the CCIMI.

If you would like to contact me, please use email.


About Me

I am interested in machine learning algorithms for imaging processing. Most of my research is in creating optimization algorithms to solve large-scale machine learning and imaging problems efficiently.

In my most recent projects, I have been developing machine learning algorithms to help clinicians interpret radiographs. I am particularly interested in bridging the gap between academic models and models that can be safely deployed in the clinic.

In March 2020, our research group helped found the AIX-COVNET collaboration, an international group of researchers developing machine learning models to aid clinicians during the COVID-19 pandemic.
