Profile Summary

I am a PhD mathematician with expertise in fractional calculus, inverse problems, partial differential equations, numerical analysis, and mathematical modeling. I completed my PhD in Mathematics from COMSATS University, Islamabad, Pakistan, in 2023 and have several years of teaching and research experience at the university level. My research focuses on fractional differential equations, generalized diffusion models, inverse source problems, regularization techniques, existence and uniqueness analysis, and the numerical approximation of complex mathematical models. I have published multiple research articles in reputable international journals, including Physica Scripta, ZAMP, and Mathematical Methods in the Applied Sciences. I have extensive experience with MATLAB, LaTeX, mathematical modeling, scientific computing, and technical writing. My expertise includes developing analytical and numerical solutions for differential equations, implementing computational algorithms, preparing research manuscripts, and assisting with data analysis and visualization. I am available for projects involving mathematical modeling, numerical simulations, MATLAB programming, LaTeX typesetting, scientific writing, research consulting, and academic collaboration in applied mathematics and related disciplines. I am committed to delivering accurate, high-quality, and timely solutions tailored to clients' research and technical requirements.
