The Student Conference in Science and Technology 2019

The Student Conference in Science and Technology was held on Wednesday October 9 13.15 - 15 at EBC in Ekmansalen and Friessalen. Two invited speakers from the faculty of Science and Technology together with students gave talks. The students also received feedback on their presentations.

Sveva Castello, master student i physics, won one of the prizes for best presentation 2019.

Toivo Tuma Niemi, master student i physics, won the other prize for best presentation 2019.

The speakers from the faculty were:

Joseph Nordgren, Senior Professor in X-ray physics
Title: X-ray Color Vision Reveals Secrets of Materials

Abstract: Spectroscopy can be seen as an augmented form of our senses, notably our vision. We can observe light in colors from deep violet to far red, and a great deal of our knowledge of our environment has been learned by observing form and color of objects around us. We cannot see shorter wavelengths than violet, so UV and X-rays are invisible by the naked eye. However, by using certain instruments, spectrometers, we can study these wavelengths and disclose secrets of matter in order to understand various phenomena that seem magic. 

I will discuss how X-ray spectroscopy can be used to reveal the electronic structure of materials and molecules that is responsible for physical and chemical properties, and which forms the basis for the function of devices and the chemical reactions that makes materials synthesis possible. In doing so I will describe the advanced scientific tools, which are the “energy and momentum microscopes” that allow us to peek into the molecules and crystals with a sharp eye. One such example is the super brilliant Swedish MAX IV X-ray light source, which I will present, that makes sunlight seem like a faint flare in the distance and which is presently becoming available for Swedish and international scientists working in a broad spectrum of scientific fields.

Markus Sjöblom, Senior lecturer in Neuroscience
Title: Melatonin – a magic hormone for a great gut feeling

Abstract: For many years, melatonin was thought to be exclusively synthesized by the pineal gland in the central nervous system, but was later shown to be released also from extrapineal sources. Pineal gland secretion of melatonin is inhibited by light and triggered by darkness, while the extrapineal derived melatonin has been shown to be secreted in a steadily fashion, or in response to acute stimulation. From a physiological point of view, the effects of melatonin are interesting to study since this hormone influence and regulate a large number of functions, such as circadian rhythms, sleep and mood patterns, scavenging of free radicals, alleviation of jet-lag, immune mechanisms, carcinogenic processes, and also digestive functions. Disorders and diseases of the gastrointestinal system, such as gastric and duodenal ulcer disease, irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD) are common in both humans and in animals, and presently there is a great need to find new therapeutic strategies.

In this lecture, I will discuss mainly the role of extrapineal derived melatonin in the regulation of normal intestinal physiological functions and its possible role as a magic hormone against potentially harmful agents in the small intestine.

The Science Conference

The student conference is a part of the communications training at the faculty. Apart from the opportunity to participate in an exciting conference you get a chance to give a presentation in front of a larger audience. As a participant the conference offers you a broadend perspective of science and the chance for networking and contacts between disciplines. 

Give a presentation

After the keynote speaker the students will take the floor and give presentations on different scientific subjects. All students are welcome to give a 15 min presentation and the conference is one of the best opportunities you can find to practice talking in front of a large audience. Take the opportunity to practice the skill that employers value as one of the most important one an employee can have. If you want to give a presentation, read more under "To give a presentation" below.

Give feedback

You can also contribute by being a feedback provider to one or several of the speakers. By giving valuable positive and constructive comments on their presentations you help them improve and at the same time practice your own skill to give and reflect on feedback.

Should you participate by both giving a presentation and giving feedback (not necessarily during the same year) you will be given a certificate of your participation which can be a valuable addition to your CV.

Naturally, all are most welcome to listen regardless if you are a speaker or not.

Register to the conference

All participants must register for the conference. You can register here.

To give a presentation

Giving a presentation at the Student Conference is to give a 15 minute presentation in front of a larger audience of about 100 persons. The presentation may be about any scientific subject of your choice and the only limitation is that everybody in the audience should be able to understand, which means giving the presentation at a level which is common for all science students, regardless of if it is biology or physics.

Presentations may be held in Swedish or English, whichever you prefer. You usually have a bigger toolbox of techniques when giving a presentation in the language you have the most experience with but depending on your goals whichever language may be suitable.

When giving an oral presentation there are a lot of things that you may want to consider to make the presentation as good as possible. Click on "Oral presentations" in the menu to the left to get som basic help.

You may also contact us who work with the communication training via e-mail ( to get coaching before and after your presentation.

Giving feedback

As a feedback provider at the Student Conference you have a responsibility to give constructive as well as positive feedback to the speaker you have been assigned. Because it probably is the first time the speaker gives a presentation in front of such a large audience the person giving feedback need to help the speaker develop in this rather special context. Regardless of level of expertise giving presentations you can always become better. And it is here you as a feedback provider comes in.

To be able to give focused and well balanced feedback to help someone improve is a skill all in its own. You can use the forms provided in DiaNa to get points of reference when giving feedback. The most important thing though, is to give feedback from your own perspective.
