Portfolio

I am a senior at Yale University double majoring in Mechanical Engineering and Visual Art.

I love understanding how things work and finding ways to improve existing devices and create new ones. I want to innovate and create things that are beautiful and can help our everyday lives.

Outside of design and engineering, I illustrate for different Yale publications, write articles, and am the president of the Bulgarian Society.

My favourite animal is the hippo.

Measuring Ejection Force
Summer 2022


Daye 

Sofia, Bulgaria 
London, UK
Daye is a British-Bulgarian start-up that innovates within the gynae health field. They produce CBD-infused tampons for women, launching the first virtual female health clinic in the UK, developed the first flushable tampon applicator, and more. 

During my time at Daye, I engineered an experimental method to measure the ejection force of CBD-coated and uncoated tampons. Due to a number of complaints from customers, they needed a quantified report as to why and how often this was occurring. 

To address the problem, I engineered a device that measured the ejection force of tampons and tested over 600 tampons from different batches. In the end of my experiment, I wrote a report addressing trends, possible reasons, and possible solutions. My report was added to Daye’s official documentation and was used to create a pamphlet for customers addressing any difficulty with tampon ejection.
