Activities
My research activities cut across the fields of biological oceanography, marine ecology, fisheries, aquaculture,
limnology, and pollution biology, providing me with a broad and
interconnected perspective on aquatic ecosystems. In the area of biological oceanography, I have applied stable isotope
techniques of carbon and nitrogen to study nutrient pathways, trophic
interactions, and energy flow in mangrove and seagrass ecosystems. I have also
investigated trace element cycling, nutrient dynamics, and the distribution of
rare earth elements in marine sediments, thereby contributing to the
understanding of biogeochemical processes that sustain productivity and
ecological balance in coastal systems such as the Red Sea.
In marine ecology, my focus has been on mangroves,
seagrasses, plankton, bivalves, and sponges, examining their ecological
interactions and roles in biodiversity conservation. I have worked on trophic
dynamics in mangrove food webs, the efficiency of seagrass in trace element
uptake, and the use of sponges as bioindicators of marine pollution. I have
also studied stress responses in mangroves, highlighting the threats posed by
environmental and anthropogenic pressures. Through these studies, I aim to
advance knowledge on the functioning and resilience of marine habitats that are
central to ecosystem services and coastal biodiversity.
My work also
extends to fisheries and aquaculture,
particularly in the areas of aquatic health and sustainability. I have studied
the biochemical and behavioral responses of freshwater bivalves to pesticide
exposure, providing insights relevant to aquaculture biosecurity. In addition,
I have explored alternative feed resources for aquaculture through the
proximate and amino acid profiling of insect larvae as potential catfish feed
ingredients, which supports innovation in sustainable aquafeed development.
These studies demonstrate the applied dimension of my research in supporting
fisheries and aquaculture under changing environmental conditions.
My background in limnology forms an important foundation of my research
career. I have investigated Nigerian reservoirs, focusing on macrobenthic
invertebrate diversity, heavy metal contamination, and the influence of water
quality on freshwater snails, particularly those serving as intermediate hosts
of Schistosoma. This work has deepened
my understanding of freshwater ecosystem structure and function while also addressing
issues of ecological health, biodiversity conservation, and public health.
A unifying theme
across my career has been pollution and
ecotoxicology. I have conducted extensive research on the
ecological risks associated with heavy metals, pesticides, and pharmaceuticals
in both marine and freshwater systems. By employing biochemical markers such as
oxidative stress, antioxidant enzyme activity, and allelopathic responses, I
have contributed to the development of biomonitoring tools for assessing aquatic
ecosystem health. This focus on pollution also extends to my work in
bioremediation, where I have explored the use of species such as Chlorella and Lemna in wastewater treatment and contaminant removal.
Overall, my
research reflects a continuum from freshwater systems to marine ecosystems,
with pollution serving as a central theme. By combining expertise in stable
isotope ecology, biodiversity monitoring, ecological risk assessment, and
aquatic toxicology, I am able to address both fundamental and applied questions
in aquatic sciences. My work contributes to advancing solutions for global
challenges in ocean health, fisheries sustainability,
aquaculture innovation, freshwater management, and pollution control,
while strengthening the link between ecological understanding and practical
conservation.
Skills
I
have expertise in stable isotope ecology, ecotoxicology, bioremediation, and
biodiversity monitoring across freshwater and marine systems. My skills include
ecological risk assessment, aquatic toxicology, pollution monitoring, and
ecosystem conservation. I am proficient in microscopy, spectrophotometry, water
quality analysis, and the use of YSI ProDSS. I have strong data analysis skills
using R, SPSS, SAS, Minitab, and GraphPad Prism, as well as experience with
ecological modeling and biomarkers for environmental monitoring. My background
also covers aquaculture nutrition, environmental biology, and restoration
ecology, supported by over 12 years of teaching, research, and international
collaboration.
Comment(s)
I have
successfully bridged limnology, marine
ecology, biological oceanography, and aquaculture, showing versatility
in working across freshwater and marine systems. This makes my expertise
valuable in multidisciplinary projects. Pollution and ecotoxicology emerge as
central themes throughout my career. By combining fieldwork, laboratory
analysis, and modeling, I have built a consistent narrative to understand and
mitigate human impacts on aquatic ecosystems. I used stable isotope analysis, biomarkers, and ecological risk assessment tools,
placing me at the cutting edge of ecosystem research. These methods are
globally relevant and highly transferable. My work also directly informs fisheries sustainability, aquaculture nutrition,
and ecosystem restoration, showing that I not only generated academic
knowledge but also provided solutions to pressing environmental and food
security challenges. In terms of collaboration, I have carried out research and
training across Nigeria, Saudi Arabia, South Africa, and Malaysia. This gives
me strong international exposure, positioning me for global collaborations and
leadership roles.
