Yeasin Arafat Rafio

I am an undergraduate student in Biological Sciences at Carnegie Mellon University in Qatar and a research fellow with the Optima Research Group. My academic interests are centered on interdisciplinary research at the convergence of biology, optics, and computation, with a particular emphasis on developing computational frameworks that enhance experimental sensing and analytical platforms.

My research motivation lies in the translation of biological and physical systems into digital and computational models that enable efficient data acquisition, interpretation, and decision-making. I am especially interested in the application of machine learning and neural networks to optical and spectroscopic data, where data-driven approaches can complement and extend traditional analytical methods.

Within the Optima Research Group, I contribute as a research intern with a focus on computational and software-based support for ongoing research activities. This includes participation in the development and maintenance of the group’s digital research infrastructure, facilitating clear dissemination of research objectives, methodologies, and outcomes. Through this role, I aim to support collaborative research while gaining deeper exposure to experimental design, optical instrumentation, and data analysis workflows.

Through my work at Optima, I seek to further develop my interdisciplinary research skills and contribute to data-driven innovations in biological and optical sciences.
