Electrochemistry

My name is Sveta. I am from Russia. I have got a master’s degree in 2010. I worked in the General Chemistry Department of the University (which? -- you used "the") for 4 years. In March of this year I came to Singapore to prepare for PhD courses (plural?).
I worked in the field of electrochemistry for about 7 years. The investigations were connected with about titanic alloys and heat-resistant alloys on the base of iron chrome and nickel. I explored electrochemical processes, selected optimum electrolytes and modes for electrochemical machining and electropolishing and carried out some corrosion studies. Also I worked on environmental issues, particularly reduction of hexavalent chrome by electrolysis and electroflotation for titanic sludge removal. I liked this part of (better to be "area in") electrochemistry and I want to continue my research in this field.

(I'm not sure if "machining" or "chrome" is correct, as this is not my field. Also, I think you mean "titanium".)
