Thank you for an amazing session of very exciting scientific questions. I can't wait for the next chat. I wish I could've answer all the questions. Please send the unanswered questions to the website so we can answer there later!

Favourite Thing: I love observing the little things that mother nature keeps in secret like where the birds go to sleep at night, the tiny creatures that live under the rocks or the beauty of a snow flake under the microscope.

About Me

I am scientist who wants to share his wisdom with the rest of the world

I have been working as scientist for quite a few years and my job has been focused on the most tinny things that bare eyes can’t see. During 5 years I studied a type of bacteria (a really small creature only visible with a microscope) that lives on the ground and eats another bacteria. This bacteria is very tiny but fierce and no other being in the microscopic world can fight it. It is like the lion in the jungle. Simply invincible. However, we don’t have anything to fear, since it doesn’t like eating humans…luckily

After working with this bacteria I started to learn for 3 years how our body fights against other tiny creatures (or microbes) that do like attaching humans. When some of these evil microbes break into our bodies, we get sick. However, the reason why we are not always sick is because, inside us, we have a tiny squadron of superheroes that patrol 24/7 searching for evil microbes to catch and immediately destroy with their amazing superpowers.

My Work

I wake up very early and have a very energetic breakfast. I never leave out the fruits since I know they have lots of vitamins which are very important to help the squadron of tiny superheroes that live inside me destroying the malevolous microbes that will surely attach me.

I have a shower and get ready to go to work in the laboratory. When I come in every day I say Good morning to all my friends that are scientists like me, put on my lab coat and gloves and go to the microscope where I observe if the tiny superheroes I grow in the lab are strong enough to be part of my experiments. If they are I will check how they respond to evil infections and extract what they have inside to fight against the evil tiny creatures.

If any exciting result comes up, I will tell my colleagues and my supervisor to find a possible explanation.

My Typical Day

What I'd do with the money

A tour through different schools

I would spend it in travelling to different schools and show the children through a self-designed card game and puzzle how immune system works.  I would make a competition among the children to see who is the best player and I would award the winner with a deck of cards of the game to him/herself. I would also get some cute teddy microbes and immune cells.

I would also show to the students how to make their own Petri dishes at home to isolate bacteria by using jelly, water, sugar and chicken stocks!!!! so they will learn the importance of our immune system to defeated the constant attacks of these invaders .
