Hey! đź‘‹ I'm Lina Marieth

I'm a research scientist and data scientist who loves making complex things make sense. I spent years in quantum physics labs building and playing with lasers, cold atoms and plasmas, and now I also apply that same curiosity to data problems and AI.

How I work

Most of my projects start with a specific question I can't let go - like whether YouTube comments actually contain useful information (spoiler: sometimes), or what forbidden atomic transitions look like when you cool rubidium to nearly absolute zero.I care about making technical things accessible. Whether it's explaining quantum physics to 1.4M people on TED-Ed, talking about AI at the UNESCO HQs, or helping women get into data science, I believe the best work happens when more people can participate.When I'm not doing research or data work, I'm usually organizing workshops, mentoring women in tech, or trying to make French grammar make sense (still working on that one).

THINGS I've BUILT

Research that advanced physics

  • First observation of the forbidden dipole transition (5P -6P) in cold Rb atoms. Read the paper

  • Led experiments at labs in USA, Mexico and UK.

  • Published 15+ peer-reviewed papers.

  • Selected among Europe's top researchers as expert evaluator by the EU Research Executive Agency to help with €1M+ Horizon research funding decisions.

  • Invited to create science communication that reached millions with the TED-Ed lesson: "What is the coldest thing in the world?" with 1.4M+ views. Watch it →

  • Built a cold plasma system from scratch to study optogalvanic effect and applied super-resolution technique to optogalvanic spectra to resolve previously undetected spectral lines. Read the paper

TALKS & WORKSHOPS

I give talks on quantum physics, AI and science at the intersection of people's real lives. The goal is always the same: leave people with real understanding they can actually use.


The New AI Player: AI in the Home Space
UNESCO Headquarters, Paris - June 2026

Solo talk delivered at the launch of Growing Up in a Connected World, a UNESCO guide on digital literacy for children and families. An intervention making AI in the home space accessible and non-scary for a non-technical audience. Event page

How to Teach Yourself Natural Language Processing

Online workshop for the WiDS community on how to self-teach NLP from scratch. The real curriculum, the honest roadmap, and why you don't need a traditional academic path to get there.

Building a Personalized arXiv Research Assistant with Google Generative AI

I built a personalized arXiv search assistant called Arxivist AId that delivers the latest research tailored precisely to your interests and timeline needs. Arxivist AId leverages Google's Generative AI capabilities to transform how we interact with scientific literature in arXiv.

COMMUNITIES I'VE BEEN PART OF

PyLadies Mexico | Co-Director 2018-2019|
Women in Data Science | Organizing Committee 2022-2023
Finding Ada Network | Mentor for women in STEM 2020-2021
I've spoken at PyLadies Amsterdam, WiDS, and other international events because I believe tech gets better when more voices are in the room.


WHAT I'M LEARNING ATM

  • Right now I'm:

  • Exploring how to teach technical skills through official documentation instead of tutorials.

  • Learning French (currently at B1 and convinced the subjunctive exists just to confuse people).

  • Figuring out how to turn research skills into content that actually helps people switch careers.

Let's work on something interesting together.
