Current Research Activities

Chemical Sciences

Dr Akens Hamilton-Amachree has undertaken several research projects in the extraction, analyses and industrial application of bioactive compounds. Her current research is on Extraction Optimisation of phytochemicals from by-products of selected plants growing abundantly in the low land rain forests of the Niger Delta Region of Nigeria. Green extraction Technologies are being explored. Her research also involves the use of hyphenated analytical techniques such as UPLC-MS, GC-MS and UV-Vis Spectroscopy in the analyses of the resultant complex plant matrices.

Current profession

Current professional activities type: 
I am currently involved in lecturing undergraduate chemistry courses as well as offering supervision to research projects. My relatively young university is yet to commence post graduate programs. I am also actively involved in collaborative researches which has led to the publication of articles in referred journals. I also have some important administrative duties namely: member, University Management Committee, member, University Senate, Director, Academic Planning.
