Our staff
Hello Everyone,
My name is Servando Lopez Leon. I am from Oaxaca, Mexico. I hold a PhD and Masters degree in Electrochemistry, additionally, I am a chemical engineer.
I worked before as a scientist, engineer and professor in different countries.
Right now in SWWS, I want to share with the students my passion for science and help them at the same time to reach their daily goals.
