In October 2015, IORMS South South Headquarters was established in The Department of Mathematics (formerly known as Mathematics and Statistics Department), Akwa Ibom State University, Ikot AKpaden. This was done at the commissioning of the South South Chapter of the Institute during a visit by the Pioneer President, Professor Funso Akingbade, to the Management of The University then headed by the Professor Eno Ibanga, the serving Vice Chancellor at that time.
The visit made way for this to become the first Chapter to be established outside Lagos State, the Commercial Capital of Nigeria. It was on this breakthrough that the University gave her full support in hosting of the first ever International conference of the Institute in Akwa Ibom State in 2018 under the leadership of her able President, professor Rasheed Ojikutu.
IORMS has by the support of the national executive, registered many members from South South part of Nigeria as members of the chapter.
