PhD Biophysics\Quantitative Genetics ·Statistical Analysis, Data Mining, Artificial intelligence, 10 years of experience

Profile Summary

I am a researcher at the Institute of Plant Physiology and Genetics, Bulgarian Academy of Sciences, with over 10 years of experience at the intersection of biophysics, quantitative genetics, and computational data science. My work spans chlorophyll fluorescence analysis (OJIP transients, JIP-test parameters), thermoluminescence, delayed fluorescence, and MR820 signal processing — applied to drought stress, micronutrient deficiency, and crop performance in wheat and maize. On the quantitative genetics side, I design and execute full GWAS pipelines including SNP filtering, LD-based haploblock construction, heritability estimation, and mixed model analysis across multi-environment trials. I implement custom Python solutions using NumPy, SciPy, scikit-learn, and matplotlib for everything from raw signal processing to publication-ready figures. My data science toolkit covers multivariate statistics (PCA, LDA/CDA, MANOVA, cluster analysis), machine learning classification, independent component analysis (ICA), functional data analysis (FDA), and Kalman filtering. I have delivered complete statistical pipelines and manuscript-ready results for pharmacological studies, plant stress research, and agronomic trait analysis. I work fully remotely, communicate clearly in English, and deliver well-documented, reproducible analyses. Whether you need a consultant for a single analytical challenge or a long-term research collaborator, I bring both deep domain expertise and hands-on computational skills to every project.
