About me

I am an experienced neuroscientist with a strong publication record and a background in molecular, cellular and systems neuroscience. I am versatile in a wide variety of traditional and cutting edge neuroscience techniques, including molecular biology, microscopy, animal behaviour, electrophysiology and optogenetics (10+years wet lab experience).

In my spare time, I tinker with data and am proficient in statistics, coding, data science and machine learning (4+years experience with Python/Pandas/Scikit-learn/etc). Check out the other tabs to take a look at some of my past projects!
