I am an experienced Ecological Modeller and R Programmer, with a passion for creating data-driven insights for conservation and biodiversity. My expertise in Spatial Ecology and Ecological Niche Modelling allows me to effectively model and analyze complex ecological systems using R programming. Over the past two and a half years, I have developed a strong understanding of spatial analyses and modelling in R, and have become well-versed in acquiring, cleaning, and georeferencing both species and climatic data. I have worked with multiple models, including eight different algorithms of three families: Tree-based, Regression-based, and Machine-Learning. I am also proficient in most spatial related R packages (raster, sp, terra, sf, tmap, leaflet, rayshader) syntax and the back and forth between them. In my recent work, I have extended my expertise beyond Ecological Niche Modelling to a wide range of quantitative modelling approaches, including quantitative population genetics, epidemiology, and network ecology. I have experience using various approaches such as game theory, differential, and markov processes. I have a strong research background in Macroecology, Biogeography, Evolution, and Ecological Niche Modelling. My work has led me to take an interest in computational and spatial ecology. Modelling ecological systems is what delights me, and I am fascinated by what can be achieved through math and code alone, and how much we can explore of the natural world through this lens. In addition to my research experience, I have also developed my own R package, sdmLit, which allows users to apply tools that analyze model performance, check environmental consistency, and build ensemble models by frequency to Ecological Niche Models. This package automates the data manipulation process and makes it easier to use literature methods, which previously required several thousand lines of code. My dedication to ecological modelling and R programming has helped me to become a skilled and detail-oriented professional. I am always eager to learn and take on new challenges, such as implementing individual-based models in spatial settings. I am confident that my skills and expertise can bring value to any project related to ecological modelling, data analysis, and conservation.
