He attended the Faculty of Industrial Chemistry within the Gheorghe Asachi Technical University of Iași, graduating as a chemical engineer.
Negoiță organized several Romanian expeditions in the Arctic: in Greenland, the northern areas of Canada, and Spitsbergen island in the (Svalbard) archipelago.
He also did some exploration on his own in Greenland and the Spitsbergen (Svalbard) archipelago, travelling approximately 300 kilometres (190 mi) on skis.
He obtained funding for the institute's research projects from private sponsors, the Romanian government and European sources.
This training improved his physical condition to the point that he was able to ski for hundreds of kilometers, resist the cold and pull a sled that weighed 50–100 kilograms (110–220 lb).
Over Antarctics lies the largest ozone hole, research regarding pollution can be made at this place, from here we can sample a lot of meteorites, find new minerals, some with special qualities that can become source for new technology.
In 2000 Negoiță gave the opening speech at the Antarctic Treaty meeting in London, before representatives of 43 countries.
The goal of the meeting was to regulate naval rules in the Antarctic Seas, and the main arguments centred on the Romanian, American and British essays.
In addition to reopening the station, the expedition's purpose was to obtain ground samples, sediments and microorganisms.
It is much easier for a country with a global position like Romania to reopen an older base than building a new one," Negoiță said at the opening of the station.
The Romanian research team intended to do bioprospecting, ecological and weather forecasting, measurement of seismic and geomagnetic activity and gathering of data regarding radio communication interference.
[6] Of the 13 polar expeditions he participated in, eight were led and organized by Negoiță.He expressed desires to do research on the Larsemann Hills by gathering samples from the soil and lakes and carrying out medical tests, pollution studies and climate change surveys.
He said, "I started to cry on my own in the middle of the frozen ice land – thinking of the luck the Chinese and Russian researchers were having.
For this reason, the Romanian Academy refused to fund the institute, although Negoiţă claimed that there were twenty researchers available in the country.
In December 2000, Romanian President Emil Constantinescu awarded Negoiță the Order of the Star of Romania, officer rank.
