Entropy and Sampling
Published:
The adaptive entropy sampling algorithm is starting to converge to something useful. The idea is simple in principle — place your next measurement where the posterior uncertainty is highest — but implementing it efficiently on large fields with complex spatial dependencies is another story.

The Beginning
Published:
So this is it. I moved from Concepcion to Santiago to start the PhD in Electrical Engineering at Universidad de Chile, funded by the CONICYT scholarship. New city, new lab, new everything. Santiago feels enormous compared to what I’m used to – louder, faster, more of everything. The first meeting with my advisors was a mix of excitement and intimidation. They laid out what the next few years would look like, and honestly, the scope of it felt overwhelming. But there’s also this feeling that I’m exactly where I need to be. The lab is small but the people are sharp, and the problems they’re working on are genuinely interesting. I keep reminding myself that everyone who’s done this felt lost at the beginning. The CONICYT scholarship takes the financial pressure off, which is huge – I can actually focus on the research without worrying about rent. One step at a time.

First SOFI Results
Published:
After weeks of debugging MATLAB code and calibrating the microscope, we got the first SOFI super-resolution images working. Second-order cumulants on quantum dot samples. The resolution improvement is visible — structures that were blurred blobs in the widefield image become distinguishable points in the SOFI reconstruction.
