  • • Statistical Modeling and Geostatistics
    • Forest Ecology
    • Agroforestry

Background

I am an Agronomist and Forester (Engineer, MSc and PhD). I followed complementary courses in Biometry (Master) and in Economics and Management (Bachelor). In Forest field, my research deals with Population Ecology, Forest Estimation and Spatial Modeling. I also teach Biostatistics and Forest Estimation lessons at Bachelor and Master Degree level at the National Universities of Benin. I play the role of Biostatistician in several national or regional research projects (IFWA, YAM Project for Africa, etc….). As a data analyst, my research is very collaborative and includes several institutions/labs and research axes.

Research project

PhD research project

My PhD research focused on the simulation of ethnobotanical indices and modeling of production dynamics of the physic nut (Jatropha curcas L. – a biofuel plant) in Benin (West Africa). Research activities established the empirical sampling distribution of bootstrap ethnobotanical indices to better analyze the diversity of endogenous knowledge and uses of J. curcas and modeled yield, germination dynamics, and stock of biomass and carbon of J. curcas. The results showed that the indices of Informant diversity and equitability value of J. curcas vary little according to the size of the respondents. According to the predictive model of seed yield, only the number of tertiary branches and total height could account for half of the variation in seed yield. The germination rate of J. curcas seeds is logarithmic. One hectare of J. curcas plantation of 1111 feet aged 3 years sequestered on average 10787.81 kg C.

Postdoc research project

My postdoctoral studies are focused on the (i) Bootstrapping knowledge and use indices for reliable estimation and inference in quantitative ethnobotany (ii) the theory of meta-analysis and its application in forestry and (iii) the Spatially explicit assessment of the suitable areas for the threatened Iroko’s (Milicia excelsa Welw. C.C. Berg) conservation in Benin : a combination of geostatistics and ecological niche modeling
