Research:

My Ph.D. thesis titled "Air Quality Evolution at the Local Scale, in the Absence of a Calibration Reference Point" addresses the critical issue of air pollution monitoring. The research proposes a collaborative initiative leveraging low-cost air quality sensors to comprehensively understand pollutant distribution and reliability across diverse geographical locations. Key methodologies include the integration of advanced machine learning techniques, satellite data, GIS, and remote sensing for calibration and monitoring. The study aims to enhance model performance through comparative analysis of retrospective data and real-time sensor deployment. Moreover, the research contributes valuable insights into air quality monitoring methodologies, aiming to develop effective mitigation strategies for environmental sustainability.

Background:

I hold both a Bachelor's and Master's degree in Civil and Environmental Engineering, specializing in environmental science and technology. Throughout my academic journey, I've gained valuable experience through involvement in key research projects and publications in internationally reputed environmental journals. My academic background has provided me with a strong foundation, propelling me towards the forefront of environmental research, where I explore the pressing need for robust air pollution monitoring methodologies especially focusing on low-cost air quality sensors. However, my focus lies not only in developing these methods but also in improving them and developing techniques so that the impact on human health can be reduced. My PhD thesis, titled 'Air Quality Evolution at the Local Scale, in the Absence of a Calibration Reference Point,' addresses this imperative by refining existing techniques and pioneering new approaches to ensure a healthier environment for all.

Madagascar Project

Madagascar Mobility Project

Mobility Sneak Peek

Culmination of an international project for my Ph.D. thesis, titled "Air Quality Evolution at the Local Scale in the Absence of a Calibration Reference Point." This ambitious endeavor was made possible through funding from the Department of GIE-GERS at Université Gustave Eiffel, the CLEAR-Doc COFUND, Université de Fianarantsoa, and Madatlas Madagascar.

At the outset, I wish to express my deepest gratitude to Dr. Hasina Rakotonirainy and Dr. Hajalalaina Aimé Richard, Director and President of Université de Fianarantsoa, respectively, for their motivation and unwavering support. My heartfelt thanks also go to my supervisors, Andry Rico Razakamanantsoa and Agnes Jullien, for their invaluable guidance and insights. Special thanks to Erwann Rayssac for his exceptional support throughout this project.

We are immensely grateful to Madatlas for facilitating the campaign, a crucial component of the emission inventory project. The primary data for this report was generated through a campaign involving approximately 40 teams of postgraduate students from Université de Fianarantsoa, who participated following comprehensive orientation training and detailed instructions on the methodology, quality assurance, and control protocols. We extend our sincere appreciation to all the student volunteers for their dedication and hard work in collecting primary data under challenging conditions.

Secondary data was obtained from reputable sources and government agencies and subsequently validated against sampled primary data bins in accordance with the project scope. We are grateful to all the agencies that provided us with this crucial secondary data. The inferences, analysis, and final product of this report are based on the primary data generated by us and secondary data collected as mentioned above.

The project could not have been completed without the active support in providing various information and secondary data from the Municipality Office Fianarantsoa (MOF), Public Hospital Fianarantsoa (PHF), and Regional Transport Office Fianarantsoa (RTOF). I extend my sincere thanks to all these agencies.

A novel gridded emission inventory for the city of Fianarantsoa has been developed using a Geographical Information System (GIS)-based statistical model, enhanced by the strategic allocation of active sensors for precise air quality monitoring.

InCITIES Program

Sharing the Journey of my InCITIES Program!

Reflecting on this incredible journey fills me with excitement!

Alongside a truly inspiring cohort, we delved deep into crucial topics such as sustainable mobility, urban planning, air quality, and transportation infrastructure resilience. Our experience was enriched by the wisdom shared by academic experts and industry leaders, including Kia Slovakia and @DPMZ, which broadened our perspectives and fostered a solution-oriented mind-set for the future.

One major highlight for me was our hands-on approach to tackling real-world issues, particularly in enhancing sustainable mobility around St. Gorazde Elementary School and Kindergarten. Collaborating with Žilina's esteemed architecture bureau, we not only collected valuable data but also brainstormed innovative approaches to address the challenges at hand.

I am profoundly grateful for the guidance and mentorship provided by Yannick Cornet, Tibor Petrov, Christina Georgouli, Lienka, Andry Rico RAZAKAMANANTSOA, Agnes JULLIEN, Virginie Etienne and GERS - Gustave Eiffel University, Laboratoire GIE (Univ Eiffel), Université Gustave Eiffel. Their support has been instrumental in shaping our journey.

Together, we are not merely envisioning the future of cities – we are actively shaping it.

Participating in the EU Horizon project seamlessly complements my ongoing PhD studies under MSCA-ClearDoc, allowing me to reinforce my dedication to advancing impactful solutions that resonate with the objectives of Horizon Europe. I'm truly grateful for the opportunity to engage in such meaningful research endeavors. Here's to a future marked by innovation, sustainability, and resilience!
