Professor Sergei Braun was born in Latvia in 1941. He studied chemical engineering, and until the early 1970s managed projects in the chemical industry of the Soviet Union.
After he submitted an application for immigration to Israel, he was dismissed from his job as head of a laboratory and supported his family by hard labor.
Upon his immigration to Israel he studied for his doctorate at the Hebrew University. He was ordained in 1982 and, went on to post-doctoral training at Cornell University (USA) with Prof. Ephraim Raker, one of the greatest biochemists of the generation.

Among the dozens of impressive developments by Sergei we can note the bio-plastic, microbiological systems to produce diamine-oxidase and even the production of poisonous toxins from snakes venoms
