    Ukraine - Tests: 7

    I'm Alex from Ukraine. I finished National Metallurgical Academy of Ukraine where I obtained a Ph.D degree in mathematical modelling and computational methods. My research is related to using statistical models to improve making decisions about the state of the objects that are evaluated by non-destructive methods (NDT). Not only does this research involve math matters, but also it involves matters concerning with developing applications for handling data, signal processing and so on. I was educated at Dnipropetrovsk national university (radio-electronic automatic department) and obtained master degree there. My major was non-destructive testing (NDT). It includes different subjects related to developing ndt devices as well as handling data obtained as a result of testing. I'm working for Dnipropetrovsk national university as an assistant professor. I have a blog, which you can visit by the following link: http://www.alex-koshulyan.name/index.php/en/

    Paulo Cabrita

    PhD

    Germany - Tests: 8 - Portfolio: 1

    I started as a physics teacher after my graduation from university but I always had in mind to become a scientist and if possible to combine that with teaching. Also, as I like biology it was always my goal as a scientist to apply physics to the study of biology. During my MSc and PhD research projects, both on plant physiology, I extented further my knowledge on plant sciences, namely plant physiology & biochemistry, plant anatomy and the experimental methods used in these disciplines. Over the last 6 years I have especialized on mathematical modelling of plant transport systems (membrane transport, phloem and xylem transport) for which I used Mathcad as my main tool for solving differential equations. Also, on the experimental level I have experience on isotope labelling, electrophysiology and the standard methods and equipment used in those fields.
