Just done my Masters degree in Control and Industrial Electronics, I also have one licenciates degree in Electrical Engineering and Computer Science.
I love to use MATLAB and to help others using it, everyday I learn something new.
Currently teaching and supporting students with several projects that use MATLAB for Biomedical Imaging.
Please don't send me emails asking for code or help, I will only help the best I can here at MATLAB Answers.
Professional Interests: Control engineering, biking, growing organic food, permaculture student (nature is my teacher)
