I have BSc and MSc in engineering physics from TUT. I defended my PhD on 22nd of August, 2013. My PhD project was about cardiac energetics and intracellular diffusion restrictions. To investigate these problems I use a combination of mathematical modeling and experimental methods. My experimental work is done on rat cardiomyocytes, the models describing the ATP production and consumption processes in a cell, are also used to analyze data from trout and from both transgenic and wild type mice.
You can download PDF of my thesis “Estimation of Diffusion Restrictions in Cardiomyocytes Using Kinetic Measurements”. The defense presentation can be viewed .
