Meet the postdoctoral researchers, graduate, and undergraduate students carrying out research within
MCMEG, working on Monte Carlo modelling and simulation applied to radiation protection and dosimetry.
Asif Amin
PhD Student in Medical Physics, Nuclear Engineering Department, UFMG
PhD researcher in medical physics at UFMG, under the supervision of Prof. Adriano Sabino and
Prof. Telma Fonseca. Holds a master's degree in theoretical nuclear physics, specializing in
modelling nuclear reaction cross sections with the TALYS code. Current research applies Monte
Carlo simulations (TOPAS–nBio) to study dose enhancement effects of gold nanoparticles in
radiation dosimetry, with broader experience in radiation transport simulation, treatment
planning, and computational dosimetry.

Mateus de Souza Resende
Master's Student, Postgraduate Programme in Nuclear Sciences and Techniques (PCTN), UFMG
Graduated in Radiology from UFMG (2025) and a member of MCMEG specializing in Monte Carlo
simulations — MCNP and PHITS — applied to internal dosimetry. Worked as a volunteer researcher
on internal dose calculations using computational phantoms (2024–2025). Now pursuing a Master's
degree researching the dosimetry of new radiopharmaceuticals and calculating specific absorbed
fractions (SAF) for mesh computational phantoms based on ICRP reference geometry.

Sâmella de Andrade Brum
Master's Student, Postgraduate Programme in Nuclear Sciences and Techniques (PCTN), UFMG
Licentiate in Physics from UFMG (2022), with a background in Electronics (POLIMIG/Vital
Brasil, 2013) and a specialization in Science and Science Communication (UFABC, 2024). Spent
much of her career teaching physics in public basic education and pre-university prep courses.
Now a Master's student supervised by Prof. Telma Fonseca, researching the radioresistance of
BY4741 yeast cells — characterizing cell behaviour before and after irradiation and the uptake
of metal nanoparticles combined with ionizing radiation.
