Favourite thing to do in science: Build simple stuff which do amazing things.
I build new and very fast electrical circuits using tiny transistors (which are invisible to human eyes) to increase the speed of internet (a very small part of it anyways).
A little bit about Fiber optic communication can be found in the video below. . At 2:56 it talks about optical receiver. When anybody uploads data from their home it is received by this optical receiver. To increase the capacity/efficiency so that more people can use the same fiber something called TDMA (Time division multiple access – we call them protocols) is implemented. A brief description of TDMA can be found in the video below ( the context is mobile network but the same principle applies in fiber optical communication).. So an optical receiver which can work with TDMA protocol is called Burst Mode receivers which is my area of focus (sorry couldnt find any link there). The goal of my research is to increase the data speed for each user (so you dont have to wait for long while you share your photos/videos) and have more user per fiber ( so that you spend as little as possible by sharing the cost).
The receiver is an electrical circuit made using transistors. Below is a very interesting video on how a circuits is made. https://www.youtube.com/watch?v=qm67wbB5GmI
Another very cool video about one of the fundamental properties of light and how its used in fiber communication can be found.
My Typical Day
check emails, use software to design circuit, meetings to exchange ideas and enjoy a cup of coffee with friends
Most of the time we spend is with software (called schematic editor) coming up with new circuit ideas and checking if they work. once we are satisfied, we draw them out again using software (called layout editor). From now on lets call them circuit chip. Then we send the circuit chip out to be manufactured by a company and wait till it comes back (typically it takes 5 months to manufacture a chip). once it comes back, they are checked if they perform as intended. Then we write a conference of journal paper to share our idea with the whole wide world.
What I'd do with the money
I will donate it to Tyndall Makerspace (where people try to materialize there ideas) or to outreach at Tyndall outreach (where they reach out to future scientist)

Were you ever in trouble at school?
off course plenty of times. wont go into details. :)
What was your favourite subject at school?
What's the best thing you've done as a scientist?
Increased the speed and reduce the size of (a class of) optical receiver using a simple trick.
What or who inspired you to become a scientist?
If you weren't a scientist, what would you be?
I dont know
Tell us a joke.
Three engineers and three accountants are traveling by train to a conference. At the station, the three accountants each buy tickets and watch as the three engineers buy only a single ticket. “How are three people going to travel on only one ticket?” asks an accountant. “Watch and you’ll see,” answers an engineer. They all board the train. The accountants take their respective seats but all three engineers cram into a restroom and close the door behind them. Shortly after the train has departed, the conductor comes around collecting tickets. He knocks on the restroom door and says, “Ticket, please.” The door opens just a crack and a single arm emerges with a ticket in hand. The conductor takes it and moves on. The accountants saw this and agreed it was quite a clever idea. So after the conference, the accountants decide to copy the engineers on the return trip and save some money (being clever with money, and all). When they get to the station they buy a single ticket for the return trip. To their astonishment, the engineers don’t buy a ticket at all. “How are you going to travel without a ticket?” asked one perplexed accountant. “Watch and you’ll see,” answered an engineer. When they board the train the three accountants cram into a restroom and the three engineers cram into another one nearby. The train departs. Shortly afterward, one of the engineers leaves his restroom and walks over to the restroom where the accountants are hiding. He knocks on the door and says, “Ticket, please.”
