I am 𝗜𝘀𝘀𝗶𝗳𝗼𝘂 𝗕𝗜𝗬𝗔𝗚𝗨𝗜, from 𝗧𝗼𝗴𝗼 . I am a 𝗗𝗔𝗔𝗗 scholarship holder and PhD candidate in Biometry at the 𝗨𝗻𝗶𝘃𝗲𝗿𝘀𝗶𝘁𝘆 𝗼𝗳 𝗔𝗯𝗼𝗺𝗲𝘆-𝗖𝗮𝗹𝗮𝘃𝗶. My doctoral thesis, funded by the 𝗗𝗔𝗔𝗗, is entitled :

''𝗙𝗿𝗮𝗰𝘁𝗶𝗼𝗻𝗮𝗹-𝗼𝗿𝗱𝗲𝗿 𝗮𝗽𝗽𝗿𝗼𝗮𝗰𝗵𝗲𝘀 𝘁𝗼 𝗽𝗮𝗻𝗱𝗲𝗺𝗶𝗰 𝗺𝗼𝗱𝗲𝗹𝗶𝗻𝗴: 𝗶𝗻𝘀𝗶𝗴𝗵𝘁𝘀 𝗳𝗿𝗼𝗺 𝗖𝗢𝗩𝗜𝗗-𝟭𝟵 𝗱𝘆𝗻𝗮𝗺𝗶𝗰𝘀.''

In my research, I focus on fractional-order approaches to pandemic modeling, particularly coinfection dynamics. The aim of my project is to develop and analyze fractional-order coinfection models that incorporate delayed transmission and lockdown strategies, using 𝗖𝗢𝗩𝗜𝗗-𝟭𝟵 𝗱𝘆𝗻𝗮𝗺𝗶𝗰𝘀 as a case study.

This work combines systematic review, mathematical modeling, and real-data validation with secondary data from Benin and Togo.

My contributions include:

• Producing a systematic review of fractional-order models in infectious disease dynamics, following PRISMA guidelines and identifying research gaps in Africa;

• Developing a fractional-order COVID-19 model with asymptomatic transmission, solved using the Homotopy Perturbation Method (HPM);

• Formulating an integro-differential coinfection model with time-delayed transmission and lockdown strategies;

• Validating an Atangana–Baleanu fractional-order coinfection model with real data from Benin and Togo.

Through this work, I aim to provide reliable forecasting tools for epidemic response, offering deeper insights into memory effects and transmission dynamics, and supporting public health authorities and policymakers in West Africa.

I am sincerely grateful to the 𝗗𝗔𝗔𝗗, (German Academic Exchange Service) for funding my doctoral scholarship and research project. I also extend my gratitude to my main supervisor, Prof. Dr. Ir.𝗥𝗼𝗺𝗮𝗶𝗻 𝗟𝘂𝗰𝗮𝘀 𝗚𝗹𝗲̀𝗹𝗲̀ 𝗞𝗮𝗸𝗮𝗶̈, for his rigorous guidance and encouragement, and to my co-supervisors, Dr (MC).

𝗕𝗿𝗶𝗮𝗻 𝗢𝗧𝗜𝗘𝗡𝗢, from 𝗞𝗲𝗻𝘆𝗮.

I am a recent Master’s graduate in 𝗦𝘁𝗮𝘁𝗶𝘀𝘁𝗶𝗰𝘀 (Biostatistics specialization) at 𝘁𝗵𝗲 𝗟𝗔𝗕𝗘𝗙 , 𝗨𝗻𝗶𝘃𝗲𝗿𝘀𝗶𝘁𝘆 𝗼𝗳 𝗔𝗯𝗼𝗺𝗲𝘆-𝗖𝗮𝗹𝗮𝘃𝗶.

I successfully defended my thesis entitled:

“𝗠𝗼𝗱𝗲𝗹𝗶𝗻𝗴 𝘁𝗵𝗲 𝗦𝗽𝗿𝗲𝗮𝗱 𝗼𝗳 𝗔𝗻𝘁𝗶𝗺𝗮𝗹𝗮𝗿𝗶𝗮𝗹 𝗗𝗿𝘂𝗴 𝗥𝗲𝘀𝗶𝘀𝘁𝗮𝗻𝗰𝗲 𝗶𝗻 𝗦𝘂𝗯-𝗦𝗮𝗵𝗮𝗿𝗮𝗻 𝗔𝗳𝗿𝗶𝗰𝗮: 𝗧𝗿𝗮𝗷𝗲𝗰𝘁𝗼𝗿𝗶𝗲𝘀 𝗮𝗻𝗱 𝗠𝗶𝘁𝗶𝗴𝗮𝘁𝗶𝗼𝗻 𝗦𝘁𝗿𝗮𝘁𝗲𝗴𝗶𝗲𝘀.”

My journey at 𝘁𝗵𝗲 𝗟𝗔𝗕𝗘𝗙 was marked by a deeply enriching academic and personal experience, which I describe as being part of a supportive and inspiring family.

I extend my sincere gratitude to the Director of 𝘁𝗵𝗲 𝗟𝗔𝗕𝗘𝗙, Professor 𝗥𝗼𝗺𝗮𝗶𝗻 𝗚𝗹𝗲̀𝗹𝗲̀ 𝗞𝗮𝗸𝗮𝗶̈, and the entire team for their outstanding leadership and continuous support throughout my studies.

I also express my heartfelt appreciation to 𝗗𝗔𝗔𝗗 Institute for their invaluable financial support, which played a pivotal role in making my academic aspirations a reality.

I now look forward to advancing my academic journey through PhD studies, contributing further to impactful research in biostatistics and public health.

𝗞𝗲𝗻𝗲𝗻𝗶𝘀𝗮 𝗔𝗯𝗱𝗶𝘀𝗮, from Ethiopia. I am a 𝗗𝗔𝗔𝗗 scholarship holder and PhD candidate in Biometry at LABEF, University of Abomey-Calavi, with a solid academic foundation in Statistics (BSc and MSc. My PhD thesis Project is :

“𝗔 𝗰𝗼𝗺𝗽𝗮𝗿𝗮𝘁𝗶𝘃𝗲 𝘀𝘁𝘂𝗱𝘆 𝗼𝗳 𝗵𝗶𝗴𝗵-𝗮𝗰𝗰𝘂𝗿𝗮𝗰𝘆 𝘀𝘂𝗿𝗳𝗮𝗰𝗲 𝗺𝗼𝗱𝗲𝗹𝗶𝗻𝗴, 𝗲𝘂𝗱𝗹𝗶𝗱𝗲𝗮𝗻 𝗯𝗮𝘀𝗲𝗱 𝗺𝗮𝗰𝗵𝗶𝗻𝗲 𝗹𝗲𝗮𝗿𝗻𝗶𝗻𝗴, 𝗯𝗮𝘆𝗲𝘀𝗶𝗮𝗻 𝗺𝗮𝘅𝗶𝗺𝘂𝗺 𝗲𝗻𝘁𝗿𝗼𝗽𝘆, 𝗮𝗻𝗱 𝘁𝗵𝗲𝗶𝗿 𝗵𝘆𝗯𝗿𝗶𝗱𝘀 𝗶𝗻 𝘀𝗼𝗶𝗹 𝘀𝗰𝗶𝗲𝗻𝗰𝗲: 𝗲𝗳𝗳𝗲𝗰𝘁 𝗼𝗳 𝗱𝗮𝘁𝗮 𝗰𝗵𝗮𝗿𝗮𝗰𝘁𝗲𝗿𝗶𝘀𝘁𝗶𝗰𝘀 𝗼𝗻 𝗽𝗿𝗲𝗱𝗶𝗰𝘁𝗶𝘃𝗲 𝗽𝗲𝗿𝗳𝗼𝗿𝗺𝗮𝗻𝗰𝗲𝘀”.

My doctoral thesis, fully funded by the 𝗗𝗔𝗔𝗗, investigates advanced modeling techniques for soil nutrient prediction and spatial data analysis. The project compares Machine Learning (ML), High Accuracy Surface Modeling (HASM), Bayesian Maximum Entropy (BME), and Hybrid approaches under varying spatial conditions and uncertainties. By integrating simulation and real-world soil data, his research aims to evaluate model efficiency, robustness, and predictive accuracy.

My contributions include large-scale simulations across diverse sample sizes and variogram models, assessment of skewness and data distribution effects, integration of multiple soil attributes (pH, SOC, Nitrogen, Bulk Density, Sand, Silt, Clay, CEC) into unified frameworks, and comparative evaluation of ML, HASM, BME, and Hybrid methods.

The outcomes of his work are designed to support researchers, agronomists, and policymakers by providing accurate, data-driven methods for soil nutrient assessment, thereby contributing to sustainable land management and food security.

I express my deep gratitude to my supervisor, Dr (MC). 𝗜𝗿. 𝗖𝗼𝗱𝗷𝗼 𝗘𝗺𝗶𝗹𝗲 𝗔𝗴𝗯𝗮𝗻𝗴𝗯𝗮, for their continuous guidance and mentorship.

I am also grateful for Labef 's Management for the high quality of their follow-up.
