Between school and work you can find me getting lost in a journal paper, sharing an evening fire with friends, creating data-driven art, or riding my bike through the city.
I combine art with data to translate unseeable systems into accurate, accessible visual narratives. By bridging data from researchers worldwide I make the field of structural biology intelligible without compromising scientific fidelity.

Casting shadows of life's nanometer toolkit with an electron beam, a technique known as **cryo-electron microscopy ([cryo-EM](https://youtu.be/qc2PbmI5qMw?si=HOvVoLZL2QZKv-PD))**, allows the reconstruction of the internal machinery of entire cells as they appear in real life. Ultimately, cryo-EM helps link a cell's nanoscale architecture to its macroscopic function across three core pillars

By creating visualizations that get to the point without rolling up your sleeves I create results that anyone can reproduce in the natural sciences.^[Wilkinson MD, Dumontier M, Aalbersberg IJ, Appleton G, Axton M, Baak A, Blomberg N, Boiten JW, da Silva Santos LB, Bourne PE, Bouwman J.

Much of my work focuses on how proteins form incredible shapes and scaffolds by banding together to sustain processes that underlie all life.^[Bustamante C. Molecular machines one molecule at a time.

# Insulin and Insulin Hexagons
Insulin's a great example.
![[lemasterdj_insulin_storage_figure.png]]
**Insulin**, a vital substance of two chains binded as one regulates our blood sugar.
Light passes through it.
Pancreatic beta-cells do the assembling.
**Insulin A-chain** unites with **B-chain.**
This is possible from a **sulfur bridge**.
This is the insulin we're familiar with.
But what about leftover insulin?
Our bodies turn to symmetry.
First it's two insulins back to back.
Called a insulin **dimer**.
Then with help from Calcium and Zinc
Band three such dimers in a circle.
Because a hexagon is an efficient packing pattern like honeycombs in a beehive, they can be rapidly disassembled by splitting into 3 dimers and further into 6 separate active insulin molecules on-the-spot.
Obtaining data from the RCSB Protein Data Bank^[Berman HM, Burley SK. Protein Data Bank (PDB): Fifty-three years young and having a transformative impact on science and society. Quarterly reviews of biophysics. 2025 Jan;58:e9. doi: 10.1017/S0033583525000034] I shared this example to visualize how cells organize what's on the inside to derive roles for parts smaller than itself. Sharing a deeper context to data by eye that's valuable for both basic and translatioal science has singlehandedly been the source of my vocation in this field.^[Ayan E, Engilberge S, Yokoi S, Orlans J, de Sanctis D, Basu S, Rive‐Mathieu E, Kepceoglu A, Mitsutake A, Demirci H.
