About Me


My full Korean name is Eunjin Lee - you can also call me Ellie. Currently, I work in IBM Emerging Technologies as a Researcher & Engineer, bridging the gap between research and industry. I explore how machine learning models can be best explained to humans in critical situations.

Outside my core role I am an IBM Senior Inventor - I have 20 patent files and 15 publishes, ranging from biometric authentication methods to smart restaurant analytics. My main interest is in applying technology to health and humanitarian causes, actively collaborating on projects in this area.



I design and develop user-centered solutions. I work on projects from the initial concept, through to the UX, prototyping and development of the product - working closely with stakeholders and end-users everystep of the way.


I specialise in the design and development of Proof of Technology projects - rapidly iterating through designs to accelerate the initial development cycle. I work with mixed fidelity design tools and various Front-End frameworks to develop the MVP. To tie it all together, I write APIs and server-side scripts using Node.js and Java.


I am an IBM Master Inventor, holding 20+ patent files and 20+ publishes. I am the case manager for multiple IBM EMEA technology areas, supporting inventors to protect their IP. I organise, participate and judge at innovation events around the world. I focus my work on humanitarian and health challenges and have worked alongside the UN, WWF and WHO to create innovative technical solutions.
