🧬 About Me 🧬

I love to solve problems.

Often the problem can be understanding a complex biological process, but it can also be as simple as fixing something that's broken (e.g. a door that jams, a bicycle, or even machine learning software). In particular, I like to apply my data science skills to better understand, or even solve, the problems we face.

I am always open to discuss possible roles 🔭 and whether my skill set can solve problems in your space!
