Anna Poryvai

A large white rectangular sheet of silica has a blotchy, dark-purple streak running along the bottom. From that streak emanate a series of bands of pastel pinks and oranges that have traveled up the sheet.

After @annaporyvai.bsky.social tried purifying her reaction product using preparative thin-layer chromatography (prep-TLC), her silica plate ended up looking like an impressionist’s attempt at painting daybreak. Read more: cen.acs.org/analytical-c...

Also and read her recent book Labwork to Leadership — warm, practical, and very real. I related to it many times. Highly recommend!

I heard Prof. Jen Heemstra speak at EPFL, and her honesty about the real challenges of academia stayed with me.

It pushed me to grow beyond technical skills. Since then, I’ve taken courses on self-leadership, management, conflict mitigation, etc.

Love prep-TLCs

This is how I want to be awarded the Nobel Prize.

It’s so empowering to learn with and from people around the world 🌍
Different cultures, same love for knowledge & science.
Makes me wish we could live in such a world everywhere — united by curiosity, not borders. ✨📚

Picture of a smiling person holding up a copy of a book.

First copies of my book are here!! As a new faculty member, I realized that in addition to my research job, I also had a leadership job…and I wasn’t prepared for that.

This book is the guide I wish I’d had then, with the goal of helping others now.

Tento týden jsme v nadaci přivítali milou návštěvu – naši stipendistku Annu Poryvai.

Do Česka zavítala až ze švýcarské École Polytechnique Fédérale de Lausanne, kam v roce 2022 vyjela na zahraniční stáž s podporou Nadace Experientia a kde nyní působí. 🇨🇭

Děkujeme za příjemné letní setkání! 🍀
