Ondrej L. Krivanek is a Czech-British physicist who has helped change the way we see the world. He is a top expert in creating and improving tools for electron microscopy. These are super-powerful microscopes that can see things as small as a single atom.
For his amazing work, he won the famous Kavli Prize for Nanoscience in 2020. This award recognized his incredible inventions that let scientists see the building blocks of matter with amazing clarity.

Early Life and Education
Ondrej Krivanek was born in Prague, the capital of the Czech Republic. He went to primary and high school there. As a teenager, he was very good at physics. He even won second place at the International Physics Olympiad in 1968, competing for his home country.
In 1968, he moved to the United Kingdom. He studied at the University of Leeds and later earned his Ph.D. in Physics from the University of Cambridge. He became a British citizen in 1975.
A Career Seeing the Unseen
After finishing his studies, Dr. Krivanek worked at universities and labs in Japan and the United States. He quickly became known for his skill with high-resolution electron microscopes. He was one of the first scientists to take pictures showing individual atoms where different materials meet in semiconductors, which are used in computer chips.
Building Better Microscopes
In the late 1970s, Dr. Krivanek began designing special parts for electron microscopes. These parts, called spectrometers, helped scientists figure out what materials were made of by analyzing how electrons passed through them. His designs were very successful, and over 500 of them were installed in labs around the world.
He also helped create important software called DigitalMicrograph. This software became the main tool for scientists to capture and study images from electron microscopes.
Fixing the Blur: Aberration Correction
One of the biggest challenges in electron microscopy was that the images were often a little blurry. This "blur" is called an aberration. Dr. Krivanek decided to solve this problem. He took a break from his job to work on a new invention: an aberration corrector.
Think of it like getting a perfect pair of glasses for a microscope. The corrector would fix the blur and make the images incredibly sharp.
In 1997, he and his team built the first successful corrector for a special type of microscope called a STEM (scanning transmission electron microscope). The improvement was amazing.
The Nion Company
That same year, Dr. Krivanek co-founded the Nion Co. to build and sell these powerful correctors. In 2000, they delivered the world's first commercial aberration corrector. It allowed scientists to see images with "sub-Ångström resolution." This means they could clearly see objects smaller than a single atom for the first time.
Nion's microscopes have led to many scientific breakthroughs. For example, scientists have used them to:
- Create maps showing where every single atom is in a material.
- Identify individual atoms inside a solid object.
- Detect the tiny "wiggles" or vibrations of a single atom.
In 2024, Nion was bought by a larger company called Bruker. Dr. Krivanek now works as a top scientific advisor there.
Major Awards and Honors
Dr. Krivanek has received many awards for his groundbreaking work. Here are some of the most important ones:
- Kavli Prize for Nanoscience (2020) - One of the biggest prizes in science.
- Fellow of the Royal Society (2010) - A high honor for scientists in the U.K.
- Honorary Doctorate from Masaryk University (2022) and the University of Leeds (2023).
- Cosslett Medal (2014) - From the International Federation of Microscopy Societies.
- Duddell Medal and Prize (2000) - From the British Institute of Physics.
- 2nd place at the International Physics Olympiad (1968).
